Introduction
The Tell-Show-Do technique represents a systematic communication methodology designed to reduce pediatric dental anxiety through structured explanation, sensory demonstration, and procedural execution. While the three-phase structure is conceptually straightforward, effective clinical implementation requires detailed attention to language selection, demonstration technique, timing, reinforcement patterns, and assessment of ongoing anxiety throughout the process. This article provides comprehensive guidance on executing each phase with maximum anxiety reduction and behavioral effectiveness.
The Tell Phase: Verbal Explanation Protocol
The tell phase creates accurate expectations through age-appropriate language emphasizing sensations rather than outcomes. The goal is not to eliminate all negative possibilities but to prepare the child for what will occur, reducing the anxiety created by unexpected sensations or sounds.
For very young children (ages 2-4 years), language should consist of simple, concrete sensory descriptions using 2-3 word phrases or short sentences. Example: "You will feel water. You will taste water. You will hear a sound. The sound is loud." Avoid complex sentence structures, technical vocabulary, or abstract concepts. Repeat key phrases to ensure comprehension. Do not introduce negative concepts such as "it won't hurt"—focus entirely on positive sensory descriptions.
For preschool children (ages 4-6 years), language becomes slightly more complex but remains concrete. Use familiar analogies and comparative language: "The tube that sucks is like a tiny straw, like the straw in a juice box you drink from. When you suck on your juice straw, the juice goes up the straw. Our straw pulls the water out of your mouth. The suction feels a little like when you sip from a straw." Provide multiple sensory descriptors: "You'll hear a gentle whirring sound. You'll feel water spray. You'll feel vibration like when you hold a toy that vibrates."
For early school-age children (ages 6-9 years), language can include cause-and-effect relationships and technical terms presented accessibly: "I'm using this mirror to look at your teeth. Mirrors reflect light so I can see areas that are hard to see otherwise. When I look, I'll also gently move the mirror around to see different teeth. You might feel the mirror is cold at first, then it warms up. You'll taste the water I use to rinse areas as I look."
For older children and adolescents (ages 9+ years), more sophisticated communication is appropriate: "I'm going to use a high-speed handpiece to remove the decayed portion of the tooth. The handpiece rotates at approximately 300,000 revolutions per minute, which is why you'll hear a high-pitched whining sound. You'll feel vibration and water spray. The carbide bur I'm using is designed to cut tooth structure while minimizing heat generation. The suction device will pull away water and debris throughout the procedure."
Critical principles for all age groups include using active, positive language; avoiding negating words ("won't," "don't," "no"); providing specific sensory descriptors (taste, touch, sound, sight); explaining the purpose of procedures ("This rinses away the decay we just removed"); and checking for understanding by asking the child to repeat or explain what they expect. "Can you tell me what you'll feel when I use the vibrating tool?" permits the provider to correct any misunderstandings before proceeding.
Voice Control and Non-Verbal Communication
Voice tone, pitch, rhythm, and volume substantially influence child anxiety during Tell-Show-Do. A calm, confident, slightly slower-than-normal speaking pace signals competence and control. Varying tone monotonously risks sounding robotic; varying pitch naturally while maintaining overall calmness improves engagement.
Volume should be moderate—loud voice startles anxious children; whispered voice creates conspiratorial anxiety. Pausing briefly between concepts permits comprehension and demonstrates that the provider is not rushed. Speaking with appropriate authority without harshness establishes that the provider is competent and in control, which reduces child anxiety.
Non-verbal communication including facial expression, body position, and gesture profoundly influences pediatric patient responses. Smiling naturally while explaining procedures creates approachability. Making direct eye contact signals attention and respect. Positioning yourself at the child's eye level rather than towering above reduces intimidation. Slow, deliberate movements project calmness; rapid movements suggest urgency or tension.
Removing sunglasses and fully exposing facial expressions during initial communication increases rapport. When performing the procedure, partially obscured facial expressions due to mask and protective eyewear are unavoidable, but during explanation and demonstration phases, maximum facial visibility supports communication.
The Show Phase: Sensory Demonstration Methodology
The show phase provides low-intensity exposure to anxiety-producing stimuli in a controlled, safe context where the child experiences that the stimuli are tolerable. Show phase intensity should be significantly reduced compared to actual procedural use. For example, the high-speed handpiece is activated outside the mouth so the child hears the sound and vibration without intraoral insertion. The suction device is activated to gentle suction on the child's finger so they experience the sensation at reduced intensity.
For dental mirror: Allow the child to hold the mirror, observe its reflective surface, note its cool temperature, and understand its purpose. Place the mirror in your own mouth so the child sees how it functions. Then gently introduce it to the child's mouth at the anterior region where it feels less threatening than posterior placement. Explain sensation: "This is cool. Now it will warm up as it sits in your mouth. You might taste a little water."
For high-speed handpiece: Activate it outside the mouth so the child hears the sound and can see it spinning. The child often experiences a marked fear reduction upon hearing the sound removed from their mouth. Permit the child to hold the handpiece (when turned off) and feel its weight and shape. Show the bur and its extremely small size, which often surprises children who imagined larger cutting instruments. Activate the handpiece again at a distance. Then, if the child permits, briefly place the non-rotating handpiece against a tooth with no rotation. This provides tactile familiarity without the sensory intensity of the rotating instrument.
For suction (high-volume evacuator): Activate at a distance so the child hears the sound. Place a finger near the suction tip so the child feels gentle air movement and mild suction without full suction force. Permit the child to control the suction intensity by moving their hand away or toward the tip. Allow the child to see the water/debris removal, which often demonstrates the purposefulness of the procedure and reduces anxiety about its function.
For air/water syringe: Activate outside the mouth so the child sees water spray and air stream. Place a finger near the spray so the child feels water and air. For spray-sensitive children, demonstrating the spray on your own hand or a tissue reduces fear. Explain: "This spray is water and air. It helps me rinse away the decay. It feels cool and wet."
The show phase duration varies with individual anxiety levels. Minimally anxious children may require 30-60 seconds of demonstration per instrument. Highly anxious children may require multiple minutes or multiple appointment phases of demonstration before the child feels ready to permit actual procedural use.
Desensitization Protocols and Graded Approach
Systematic desensitization involves progressive exposure to anxiety-producing stimuli with increasing intensity across sequential appointment phases. Initial appointments focus on extraoral examination, establishing rapport, and introducing basic instruments without active use. Subsequent appointments gradually introduce instruments and procedures.
For a highly anxious new child, the first appointment might consist entirely of exploration and Tell-Show-Do without any instrumentation. The second appointment might include gentle mirror examination without scaling or cutting instruments. The third appointment might introduce passive suction. The fourth appointment might introduce gentle hand instrumentation. This staged approach permits anxiety extinction over multiple exposures.
Graded procedures within a single appointment follow similar principles. Begin appointments with non-threatening procedures (mirror examination, suction placement) before advancing to anxiety-producing procedures (high-speed handpiece work). By the time the child reaches more anxiety-producing phases, they've experienced successful cooperation and positive reinforcement, which supports continued cooperation.
The provider should explicitly communicate the structure to the child: "Today we're going to look at your teeth and show you the tools we use. Next time we come, we'll use some of the tools gently. As you get comfortable, we'll use more tools." This transparency reduces anxiety created by uncertainty about what will happen.
Positive Reinforcement During Tell-Show-Do
Positive reinforcement should be delivered immediately and frequently during Tell-Show-Do procedures. Rather than waiting until the complete procedure concludes, reinforce successful completion of small steps. After the child permits mirror placement without resistance: "Great cooperation! You kept your mouth open perfectly. That helps me see your teeth really well." After suction is tolerated: "Excellent! You stayed so still while I removed the water. That made my job much easier."
Verbal praise should be specific and genuine. Generic praise ("good job") lacks the reinforcing power of specific praise ("You're doing such an excellent job keeping your mouth open"). Praise should focus on effort and cooperation rather than personality: "You're working so hard to sit still" rather than "You're such a good girl." This directs the child's attention to controllable behaviors (effort, cooperation) rather than fixed traits.
Tangible rewards provide additional reinforcement, particularly for younger children or highly anxious children. Small toys, stickers, or certificates delivered at the end of the appointment reinforce overall cooperation. Some practices use token economy systems where the child earns tokens for cooperative behaviors, exchanging accumulated tokens for larger rewards.
Parental praise and approval constitute powerful reinforcement. When parents visibly approve ("I'm so proud of how brave you were") or express surprise at the child's accomplishment ("I didn't think you would do so well"), the child experiences social validation that extends beyond the dental setting.
Anxiety Assessment and Dynamic Adjustment
Pre-appointment anxiety assessment informs Tell-Show-Do strategy modification. The Frankl scale categorizes behavior: definitely positive (friendly, interested, eager cooperation), positive (willing cooperation with hesitation), negative (defiant, uncooperative, negative attitude), and definitely negative (intense refusal, loss of control). Initial assessment determines whether standard Tell-Show-Do will be effective or whether modified approaches are necessary.
The Modified Child Dental Anxiety Scale (MCDAS) uses child self-report to quantify anxiety regarding specific dental situations. Scores above threshold values identify clinically significant anxiety. Some children with MCDAS scores above threshold benefit from modified approaches, longer show phases, or pharmacologic behavior guidance.
Continuous assessment during Tell-Show-Do procedures permits real-time strategy modification. Observable signs of increasing anxiety include muscle tension, jaw clenching, withdrawal from instruments, eye widening, increased breathing rate, or verbalized fear ("I'm scared," "Stop"). When these signs appear, the provider should pause and determine whether to continue with additional reassurance, repeat the show phase, implement distraction, or pause treatment temporarily.
Hand-raising signals (child raises hand to pause procedure) provide children with a sense of control and reduce anxiety created by helplessness. Explaining that a raised hand will immediately stop the procedure, combined with reinforcing hand raises that actually do pause the procedure, teaches the child that their concerns are respected and manageable. Children who raise hands rarely actually need to stop; the sense of control reduces panic response.
Voice Control Integration
Voice control—the use of tone, volume, pacing, and inflection—complements Tell-Show-Do telling and demonstration. Confidence in voice tone signals provider competence and control. Calm tone signals safety. Slight slowing of speech rate permits processing and demonstrates lack of urgency. Appropriate pause length before proceeding to procedures provides final opportunity for the child to process information.
Voice control during procedures should maintain calm confidence while avoiding monotone delivery. Brief, purposeful commands ("Open a bit wider," "Relax your jaw") delivered in calm, confident tone guide child behavior more effectively than lengthy explanation during active procedures. Periodic positive reinforcement ("You're doing great") maintains motivation and cooperation throughout.
Documentation of Tell-Show-Do Process
Clinical documentation should note which behavior guidance techniques were employed, the child's response to each phase, specific anxiety indicators observed, modifications made, and ultimate behavioral outcome. Example documentation: "Pt. exhibited moderate anxiety (Frankl positive). Used Tell-Show-Do with extended show phase. Permitted mirror exam without resistance after demonstration. Initial reluctance regarding suction resolved after demonstrating on finger. Permitted gentle hand instrumentation with positive reinforcement. Cooperative throughout appointment. Pt. education regarding home care provided."
This documentation creates a record that informs subsequent appointments and establishes the standard of care. If a child's cooperation is questioned, documentation demonstrates that systematic behavior guidance was employed.
Contraindications and Limitations
Tell-Show-Do proves less effective in several scenarios. Significant behavior disorders, autism spectrum disorder with sensory processing difficulties, or severe anxiety disorder may require alternative approaches. Acute pain often precludes adequate Tell-Show-Do implementation; emergency pain relief may be necessary before systematic behavior guidance.
Children with previous negative dental experiences may demonstrate conditioned fear responses requiring extended desensitization or possible pharmacologic behavior guidance. Certain medical conditions (severe cardiac anxiety, PTSD) may require modified approaches or referral to specialists experienced in anxiety management.
Conclusion
Effective Tell-Show-Do implementation requires detailed attention to verbal explanation quality, demonstration methodology, timing, reinforcement patterns, and continuous anxiety assessment. Providers who master the detailed techniques of Tell-Show-Do delivery—from precise language selection to non-verbal communication, from graded desensitization to immediate positive reinforcement—maximize anxiety reduction and behavioral cooperation. The technique remains the cornerstone of pediatric behavior guidance, supported by extensive evidence and refined through decades of clinical experience.
