Dental Anxiety in Children: Signs, Causes & Treatment

What Is Dental Anxiety in Children?

Dental anxiety in children is an emotional response characterized by fear, worry, and distress related to dental visits and procedures. It ranges from mild nervousness to severe dental phobia that prevents children from receiving necessary dental care. Understanding the difference between normal nervousness and problematic anxiety helps parents and dentists provide appropriate support.

Many children feel some degree of nervousness or apprehension before visiting the dentist. This is a completely normal response to an unfamiliar environment with strange sounds, smells, and the prospect of having someone examine their mouth. Most children manage these feelings well when they receive a warm welcome and clear explanations of what will happen during their visit.

However, when this nervousness escalates to a level where it significantly interferes with the child's ability to cooperate during dental examinations and treatments, it becomes classified as dental anxiety. Children with dental anxiety may exhibit behaviors that make routine dental care challenging or impossible, such as crying uncontrollably, refusing to open their mouths, or becoming physically resistant to treatment.

At its most severe, dental anxiety becomes dental phobia (also known as odontophobia or dentophobia). Children with dental phobia experience intense, irrational fear that leads them to completely avoid dental care. This avoidance can have serious consequences for their oral health, as untreated dental problems often worsen over time, potentially leading to pain, infections, and more complex treatment needs.

The Impact of Dental Anxiety on Children's Health

Dental anxiety doesn't just affect a child's experience at the dentist—it can have far-reaching consequences for their overall health and wellbeing. Children who avoid dental care due to anxiety are more likely to develop cavities, gum disease, and other oral health problems. These conditions can cause pain, difficulty eating, and may affect their speech development and social confidence.

Research shows that dental anxiety in childhood often persists into adulthood if left untreated. Adults who were anxious children frequently continue to avoid dental care, leading to a cycle of poor oral health that becomes increasingly difficult to break. This is why early intervention and appropriate support for anxious children is so important—it sets the foundation for a lifetime of healthy dental habits.

The psychological impact of dental anxiety should not be underestimated either. Children may experience anticipatory anxiety for days or weeks before scheduled appointments, disrupting their sleep and daily activities. They may also develop generalized anxiety about medical procedures or healthcare settings if their dental fears are not addressed appropriately.

Prevalence and Risk Factors

Studies consistently show that dental anxiety affects a significant proportion of the pediatric population. Research indicates that approximately 9-20% of children worldwide experience notable dental anxiety, with about 3-6% suffering from severe dental phobia. These rates vary somewhat between countries and populations, influenced by factors such as access to pediatric dental care and cultural attitudes toward dentistry.

Dental anxiety typically first appears between ages 4-8, coinciding with children's developing cognitive abilities and increasing awareness of potential pain or discomfort. However, it can emerge at any age, particularly following a negative dental experience. Children who have their first dental visit at a young age, before any problems develop, are generally less likely to develop significant anxiety.

What Causes Dental Anxiety in Children?

Dental anxiety in children develops from multiple factors including previous painful dental experiences, fear of pain or the unknown, learning anxiety from parents, sensory sensitivities to dental clinic environments, and feeling a lack of control during procedures. Understanding these causes helps parents and dental professionals develop targeted strategies to address each child's specific fears.

The causes of dental anxiety in children are complex and multifaceted, often involving a combination of factors rather than a single cause. By understanding what contributes to a child's fear, parents and dental professionals can develop more effective strategies for helping them overcome their anxiety. Here we explore the most common causes in detail.

Previous Painful or Traumatic Experiences

One of the most significant contributors to dental anxiety is a previous negative experience during dental treatment. When a child experiences pain during a procedure—whether from inadequate anesthesia, a painful injection, or an unexpected sensation—they may develop a strong fear of similar experiences happening again. The memory of pain can be particularly powerful in young children, who may not fully understand that the pain was temporary or that measures can be taken to prevent it in the future.

Traumatic experiences don't necessarily have to involve significant pain to create lasting anxiety. A child who felt restrained against their will, who was scolded for not cooperating, or who was exposed to frightening sights or sounds may develop anxiety even if the actual procedure was relatively painless. The emotional experience of feeling scared, helpless, or out of control can be just as impactful as physical pain.

Fear of the Unknown

Children naturally fear what they don't understand. The dental clinic environment is full of unfamiliar elements that can seem threatening to a young child: the strange-looking equipment, the distinctive sounds of dental instruments, the bright overhead lights, and the unusual smells of dental materials. Without proper preparation, a child may imagine worst-case scenarios about what these unfamiliar things might do to them.

First dental visits are particularly challenging because the child has no frame of reference for what will happen. Even if parents try to prepare their children, the reality of sitting in the dental chair for the first time can be overwhelming. This is why many pediatric dental practices schedule introductory "happy visits" where children can explore the environment and meet the staff without any treatment being performed.

Learning from Parents and Others

Children are highly attuned to their parents' emotions and behaviors. If a parent expresses their own dental fears—whether through direct statements like "I hate going to the dentist" or subtle cues like visible nervousness before appointments—children often absorb and mirror these attitudes. Research has shown a clear correlation between parental dental anxiety and children's fear of dental treatment.

This learned anxiety can also come from siblings, peers, or media portrayals of dentistry. Children who hear frightening stories about dental visits from other children, or who see exaggerated depictions of painful dental procedures in movies or television, may develop anxiety before they've even had their first dental experience. Well-meaning but poorly phrased comments, such as telling a child "don't worry, it won't hurt," can inadvertently introduce the concept of pain.

Sensory Sensitivities

Many children are particularly sensitive to sensory stimuli, and the dental environment provides an intense sensory experience. The high-pitched sound of dental drills, the strong taste of dental materials, the feeling of instruments and gloved fingers in the mouth, and the bright lights shining into their eyes can all trigger anxiety in sensory-sensitive children.

Children with conditions such as autism spectrum disorder, sensory processing disorder, or ADHD may find the sensory aspects of dental visits particularly overwhelming. These children may need special accommodations, such as noise-canceling headphones, dimmed lights, or more gradual introduction to dental instruments, to manage their anxiety effectively.

Feeling Out of Control

The dental setting inherently places children in a vulnerable position. They must sit still with their mouth open while an adult they may not know well performs procedures on them. For many children, this lack of control is the core of their anxiety. They cannot see what is happening, cannot predict what sensation will come next, and may feel unable to communicate their needs.

This sense of helplessness is particularly distressing for children who are accustomed to having some autonomy in their daily lives. It can be intensified if they feel that adults are not listening to their concerns or are dismissing their fears. Conversely, children who are given appropriate choices and control—such as the ability to signal for a break—often cope much better with dental treatment.

Personality and Temperament

A child's inherent personality plays a role in their susceptibility to dental anxiety. Children with naturally anxious temperaments, those who are shy in new situations, or those who have difficulty adapting to change may be more prone to developing dental fears. Similarly, children who have general anxiety disorder or other anxiety-related conditions often experience heightened dental anxiety.

Understanding that temperament plays a role helps frame dental anxiety not as a behavioral problem to be corrected, but as a natural variation that requires patient, supportive management. These children may need more time to warm up, more frequent short visits, and more extensive use of anxiety-reduction techniques.

How Can I Tell If My Child Has Dental Anxiety?

Signs of dental anxiety in children include crying and distress before appointments, refusing to cooperate or open their mouth, excessive talking or questioning, physical symptoms like sweating and rapid breathing, anger or tantrums related to dental visits, and sleep disturbances before scheduled appointments. Severe dental phobia involves complete avoidance and panic responses.

Recognizing dental anxiety in children is essential for addressing it effectively. However, children express their anxiety in different ways depending on their age, personality, and the severity of their fear. Some signs are obvious, while others are more subtle and may be easily overlooked. Parents and caregivers who understand these signs can seek appropriate help earlier, preventing anxiety from escalating.

Behavioral Signs

The most common behavioral indicator of dental anxiety is visible distress related to dental appointments. Many anxious children cry, cling to their parents, or verbally express that they don't want to go to the dentist. This distress may begin days before the appointment or may only appear when arriving at the dental office.

Some children express their anxiety through excessive talking or questioning. They may ask the same questions repeatedly ("Will it hurt? What will they do? Do I have to go?"), often as a way of processing their anxiety or as a delaying tactic. Other children become uncharacteristically quiet and withdrawn, shutting down rather than expressing their fears verbally.

During dental appointments, anxious children may refuse to cooperate with the dental team. Common behaviors include:

• Refusing to open their mouth or keeping it tightly closed
• Covering their face or mouth with their hands
• Turning their head away from the dentist
• Crying or screaming during procedures
• Attempting to leave the dental chair or the room
• Pushing away dental instruments or the dentist's hands

Some children initially cooperate but become increasingly resistant as the appointment progresses, particularly when procedures become more involved. They may have been willing to have their teeth counted but refuse when it's time for cleaning or when they see unfamiliar instruments.

Physical Signs

Anxiety triggers the body's stress response, producing various physical symptoms that parents and dental staff can observe. These include:

• Rapid or shallow breathing
• Increased heart rate (visible as a pulsing neck or complaints of a racing heart)
• Sweating, particularly on the palms, forehead, or underarms
• Muscle tension, often visible as clenched fists, stiff body posture, or gripping the armrests
• Pale appearance or flushed face
• Feeling sick to the stomach or actual vomiting (in severe cases)

In more severe cases, children may experience symptoms similar to a panic attack, including trembling, difficulty breathing, dizziness, or a feeling of unreality. These symptoms indicate severe anxiety that requires specialized management.

Emotional and Psychological Signs

Beyond the observable behaviors, dental anxiety affects children emotionally in ways that may manifest in other areas of their lives. Parents may notice:

• Sleep disturbances in the days leading up to an appointment, including nightmares or difficulty falling asleep
• Changes in appetite or complaints of stomachaches on the day of the appointment
• Increased irritability or mood changes related to upcoming visits
• Avoidance behaviors, such as "forgetting" to mention appointment reminders or hiding appointment cards
• Regression in behavior, such as a previously toilet-trained child having accidents

When Normal Nervousness Becomes a Problem

The key distinction is whether the anxiety prevents the child from receiving necessary dental care. A child who is nervous but ultimately cooperates with examination and treatment has normal nervousness. A child whose fear significantly disrupts dental visits or leads to avoidance of care has dental anxiety that warrants intervention.

How Can Parents Help Prevent Dental Anxiety?

Parents can help prevent dental anxiety by scheduling early positive dental visits before problems develop, using positive language about dental care, avoiding sharing their own dental fears, preparing children with books and videos, choosing pediatric dentists experienced with children, and maintaining their own calm demeanor during visits.

Prevention is always preferable to treatment, and parents play a crucial role in shaping their children's attitudes toward dental care. By taking proactive steps from an early age, many cases of dental anxiety can be prevented entirely. The following strategies have been shown to be effective in establishing positive associations with dental care.

Start Dental Visits Early

One of the most effective preventive strategies is beginning dental visits at a young age, ideally around the child's first birthday or within six months of their first tooth appearing. These early visits serve multiple purposes: they allow the dentist to monitor dental development, provide parents with guidance on oral hygiene and diet, and—crucially—help the child become familiar with the dental environment before any treatment is needed.

When a child's first dental experiences are simple, non-threatening check-ups rather than treatment for problems, they are much more likely to develop a positive attitude toward dental care. These "well-child" visits establish the dental office as a normal, safe place and build a relationship with the dental team before any challenging procedures are necessary.

Be Mindful of Your Own Attitudes

Children are highly perceptive and pick up on parental anxiety even when it's not explicitly expressed. If you have dental anxiety yourself, try to:

• Avoid discussing your fears around your child or in ways they might overhear
• Model calm behavior when talking about dental visits
• Share positive experiences rather than focusing on negative ones
• Consider addressing your own anxiety so you can better support your child

If you cannot accompany your child to appointments without showing anxiety, consider having another trusted adult—a partner, grandparent, or family friend who is comfortable with dental care—take the child instead.

Use Positive, Accurate Language

The words you use to describe dental visits matter significantly. Avoid phrases that might inadvertently introduce fear, such as "It won't hurt" (which introduces the concept of pain) or "Don't be scared" (which suggests there's something to fear). Instead, use neutral or positive language:

• "The dentist will count your teeth and make sure they're healthy."
• "The special chair goes up and down like a ride."
• "You get to show the dentist how well you brush your teeth."

If your child asks whether something will hurt, be honest but reassuring. You might say, "Sometimes there's a little pinch, but it goes away quickly and the dentist will help you feel comfortable."

Prepare Your Child Appropriately

Age-appropriate preparation helps reduce fear of the unknown. For young children, this might include:

• Reading children's books about visiting the dentist
• Watching child-friendly videos about dental visits
• Playing dentist at home with dolls or stuffed animals
• Letting the child practice opening their mouth wide and having teeth counted

However, don't over-prepare. Talking about the visit constantly or rehearsing too much can increase anxiety rather than reduce it. A balanced approach—providing information when asked and casual preparation activities—works best.

Choose the Right Dental Practice

The dental environment and the approach of the dental team significantly impact children's experiences. Look for practices that:

• Specialize in or have significant experience with pediatric patients
• Have a child-friendly waiting area with age-appropriate activities
• Employ staff who are trained in child behavior management
• Take time to explain procedures in child-friendly terms
• Allow parents to be present during treatment if desired

How Is Dental Anxiety in Children Treated?

Dental anxiety in children is primarily treated through behavioral techniques including the Tell-Show-Do method, gradual exposure therapy, relaxation training, and positive reinforcement. For more severe cases, pharmacological options include nitrous oxide (laughing gas), oral sedation medications, and general anesthesia for extensive treatment or extreme phobia.

When a child develops dental anxiety, there are many effective strategies and treatments available to help them overcome their fears and receive necessary dental care. The approach used depends on the severity of the anxiety, the child's age and maturity, and the specific procedures needed. Treatment typically begins with behavioral techniques and progresses to pharmacological options only if necessary.

Behavioral Techniques

For most children with mild to moderate dental anxiety, behavioral techniques are highly effective and are the first-line approach recommended by pediatric dental organizations worldwide. These techniques require patience and consistency but lead to lasting improvement in the child's comfort with dental care.

Tell-Show-Do Technique

The Tell-Show-Do technique is a cornerstone of pediatric dentistry and is particularly valuable for anxious children. The dentist first tells the child what will happen using age-appropriate language, then shows them the instruments and demonstrates on a model or their finger, and finally does the procedure. This approach eliminates surprises and gives children a sense of what to expect.

For example, before using a dental mirror, the dentist might say: "I'm going to use this special mirror to look at your teeth. See how it's round and shiny? Let me show you how it looks in my hand. Now I'll put it in your mouth so I can see all your teeth like a superhero with x-ray vision."

Gradual Exposure

Systematic desensitization involves gradually exposing the child to increasingly challenging aspects of dental care, starting with the least threatening and progressively working up to more involved procedures. A typical progression might be:

1. Simply visiting the waiting room and meeting staff
2. Sitting in the dental chair without any treatment
3. Having the chair move up and down
4. Having the dentist count teeth with a mirror
5. Having teeth cleaned with a gentle brush
6. More advanced procedures as comfort increases

Each step is repeated until the child is comfortable before moving to the next. This approach may require multiple visits but leads to genuine comfort rather than just forced tolerance.

Relaxation Techniques

Teaching children simple relaxation techniques gives them tools to manage their anxiety. The dental team can teach children:

• Deep breathing exercises ("Blow up your belly like a balloon, then let it slowly go down")
• Progressive muscle relaxation (tensing and releasing muscle groups)
• Guided imagery (imagining a favorite place or activity)
• Counting or distraction techniques

When children practice these techniques at home and use them during dental visits, they develop a sense of control over their anxiety response.

Giving Control and Using Stop Signals

A significant source of dental anxiety is feeling powerless. Giving children appropriate control can dramatically reduce their fear. Common strategies include:

• Letting the child raise their hand to signal for a break
• Offering choices when possible ("Would you like the strawberry or grape-flavored toothpaste?")
• Allowing them to hold a mirror to watch what's happening
• Letting them hold the suction tube or other non-dangerous equipment

When children know they can stop the procedure if needed, they often feel less anxious and actually need fewer breaks than children who don't have this option.

Pharmacological Options

When behavioral techniques alone are insufficient, various pharmacological options can help anxious children receive dental care. The choice depends on the severity of anxiety, the extent of treatment needed, and the child's medical history.

Nitrous Oxide (Laughing Gas)

Nitrous oxide is a mild sedative inhaled through a small mask placed over the nose. It produces a relaxed, calm feeling while the child remains fully conscious and responsive. Benefits include:

• Quick onset and recovery (effects wear off within minutes)
• Adjustable level of sedation during the procedure
• No lingering effects—child can return to normal activities immediately
• Established safety record in pediatric dentistry

Nitrous oxide is most effective for mild to moderate anxiety and works best in children around age 6 and older who can understand and cooperate with breathing through their nose. It may not be sufficient for severely phobic children or extensive procedures.

Oral Sedation

For children with more significant anxiety, oral sedation involves giving medication by mouth before the dental appointment. Common medications include midazolam and other benzodiazepines. The child becomes drowsy and relaxed, though still conscious.

Key considerations for oral sedation:

• Medication is given at the dental office and takes effect over 20-30 minutes
• The child will be groggy and may not remember the procedure
• Monitoring of vital signs is required throughout treatment
• The child must be supervised for several hours after the procedure
• No school or childcare on the day of sedation

General Anesthesia

General anesthesia, where the child is completely asleep during treatment, is reserved for specific situations:

• Severe dental phobia that prevents all treatment with other methods
• Extensive treatment needs requiring lengthy procedures
• Very young children who cannot cooperate with treatment
• Children with special healthcare needs that affect cooperation

While general anesthesia allows necessary treatment to be completed, it does not address the underlying anxiety. Children treated under general anesthesia should still receive behavioral support to help them manage future dental visits without anesthesia.

Specialist Referral

Children with severe dental anxiety or phobia may benefit from referral to a pediatric dental specialist (pedodontist). These dentists have additional years of training specifically in treating children, including those with behavioral challenges, medical conditions, and severe anxiety. Specialist practices often have:

• More experience with anxious children
• Access to sedation options not available in general practices
• Environments specifically designed for children
• Connections with child psychologists and other specialists when needed

How Can Parents Help During Dental Visits?

Parents can help during dental visits by staying calm themselves, arriving early to allow settling time, being present in the treatment room if helpful, avoiding excessive reassurance, following the dental team's lead, using agreed-upon supportive phrases, and praising the child's effort afterward regardless of the outcome.

Your role as a parent during your child's dental visits is important but requires balance. You want to provide support without inadvertently reinforcing anxiety or interfering with the dental team's behavior management techniques. Here's how to be most helpful.

Before the Appointment

Preparation begins before you even leave home. On the day of the appointment:

• Don't mention the appointment too far in advance for very young children, as this gives them time to worry
• Keep the morning calm and follow normal routines
• Arrive early to allow time to settle rather than rushing in at the last minute
• Bring a comfort item if your child has one (though check if it's allowed in the treatment room)
• Avoid making promises you can't keep ("It won't hurt at all")

During Treatment

Whether you're in the treatment room or waiting outside depends on your child's preference, the dental team's recommendations, and what works best for your family. If you're present:

• Stay calm—your child will pick up on your anxiety
• Follow the dental team's lead—they have training in managing children's behavior
• Avoid excessive reassurance or constant talking, which can increase anxiety
• Use agreed-upon phrases ("You're doing great" rather than "It's almost over")
• Don't negotiate or bribe during procedures—this can be counterproductive
• Hold your child's hand if it helps them, but let them focus on the dental team

After the Appointment

How you respond after the appointment affects future visits:

• Praise your child's efforts regardless of how the appointment went ("I'm proud of you for trying")
• Don't criticize if they were uncooperative—they did their best with the skills they had
• Consider a small reward or special activity (established beforehand, not as a bribe)
• Talk about what went well to reinforce positive memories
• Don't dwell on difficulties—move forward positively

When Should You Consider a Specialist?

Consider referral to a pediatric dental specialist (pedodontist) if your child's anxiety prevents routine care, previous attempts at regular clinics have failed, your child has special healthcare needs, extensive dental work is needed, or the anxiety is significantly affecting oral health. Specialists have advanced training in child behavior management and access to sedation options.

While many children with dental anxiety can be successfully treated in a general dental practice, some situations warrant referral to a specialist. Pediatric dentists (pedodontists) complete an additional 2-3 years of training after dental school, focusing specifically on treating children from infancy through adolescence, including those with behavioral challenges, anxiety, and special needs.

Indications for Specialist Referral

Consider seeking specialist care if:

• Your child's anxiety is severe enough to prevent routine dental care
• Previous attempts at your regular dentist have been unsuccessful
• Your child has special healthcare needs (autism, developmental delays, medical conditions)
• Extensive dental work is needed that may overwhelm an anxious child
• The child's oral health is suffering due to avoided appointments
• Sedation or general anesthesia may be required

What to Expect from a Specialist

Pediatric dental specialists offer:

• Child-focused environments with age-appropriate decor and entertainment
• Staff trained specifically in working with children
• Advanced behavioral management techniques
• Access to nitrous oxide, oral sedation, and general anesthesia when needed
• Collaboration with other specialists such as child psychologists
• Experience with the full range of childhood dental conditions and behaviors
