1. The simple difference
Tell-Show-Do and voice control are both behavior guidance techniques in pediatric dentistry, but they solve different problems. Tell-Show-Do helps a child understand what will happen. Voice control helps redirect attention or stop unsafe behavior when the child is not responding to normal communication.
Tell-Show-Do is usually preventive. You use it before the procedure so the child knows what to expect. Voice control is usually corrective. You use it briefly when behavior needs immediate direction, especially if sudden movement could make treatment unsafe.
This behavior topic connects to almost every pediatric article in this folder. A child must cooperate safely for stainless steel crown preparation, primary molar pulpotomy, trauma examination, extraction decisions, and space-maintainer appointments.
2. Tell-Show-Do
Tell-Show-Do means exactly what it says. First, tell the child what you are going to do using words that match the child’s age and development. Then show the child the sound, feeling, movement, or instrument in a safe, non-threatening way. Then do the procedure without suddenly changing the plan.
The technique works because many children fear the unknown more than the actual procedure. When the child understands the sequence, the appointment feels less unpredictable. The child is not being tricked. The child is being prepared.
In a trauma visit such as primary tooth intrusion management, Tell-Show-Do may be shortened because the child is already distressed. But the principle still helps: explain simply, show gently, then examine safely.
Exam phrase
“Tell-Show-Do involves explaining the procedure in child-friendly language, demonstrating it in a non-threatening way, and then carrying it out as explained to reduce anxiety and improve cooperation.”
3. Voice control
Voice control is not shouting. It is deliberate modulation of the voice: volume, tone, pace, or firmness. The aim is to gain the child’s attention, guide behavior, and prevent unsafe movement.
A simple example is a child suddenly reaching for the handpiece or moving during local anesthesia. A calm but firm “hands down” or “stay still” may be safer than continuing softly while the child moves into danger.
Voice control must stay professional. It should never become humiliation, anger, sarcasm, threat, or loss of control by the clinician. If the dentist sounds emotionally out of control, that is not voice control. That is poor behavior management.
Safe wording
“Voice control is a controlled change in voice tone, volume, or pace to gain attention and direct behavior. It should be brief, professional, and explained to parents when needed.”
4. Main comparison
The clean exam comparison is that Tell-Show-Do is explanatory and desensitizing, while voice control is directive. Tell-Show-Do builds cooperation before the procedure. Voice control redirects behavior during the procedure.
Neither technique replaces empathy. Tell-Show-Do can fail if the explanation is too long, too technical, or dishonest. Voice control can fail if it frightens the child or parent. The dentist must match the technique to the child, parent, and clinical risk.
| Point | Tell-Show-Do | Voice control |
|---|---|---|
| Main aim | Prepare and desensitize the child | Gain attention and direct behavior |
| Timing | Before and during procedure | Usually during unsafe or disruptive behavior |
| Style | Explanatory and reassuring | Firm, brief, controlled, and professional |
| Best use | New procedures, first visits, anxious children | Sudden movement, loss of attention, unsafe behavior |
| Common mistake | Over-explaining or using scary words | Confusing firmness with shouting |
5. When Tell-Show-Do is the better first step
Tell-Show-Do is usually the better first step for a child who is anxious, uncertain, visiting for the first time, or facing a new instrument. It helps the child build a mental picture of what will happen.
It is also useful before preventive care, examination, radiographs, local anesthesia, rubber dam placement, simple restorations, stainless steel crown preparation, and appliance checks. The technique can be adapted to the child’s age. A four-year-old and a twelve-year-old should not receive the same explanation.
For example, before managing rampant caries in a child, Tell-Show-Do may help the child tolerate examination, fluoride varnish, SDF application, or staged restorative care.
Many cavities, anxious child?
Start with disease control and behavior guidance. A long treatment plan fails if the child cannot tolerate the first safe steps.
6. When voice control may be appropriate
Voice control may be appropriate when the child is capable of understanding but is not attending, is moving suddenly, or is behaving in a way that makes the procedure unsafe. It can be useful during moments where a fast, clear instruction prevents injury.
The key phrase is “capable of understanding.” Voice control is not a good answer for a child who cannot process the instruction because of age, developmental delay, communication difficulty, extreme anxiety, pain, or sensory overload. In those cases, changing the voice may worsen the situation.
Voice control should be short. Once the child’s attention is regained, return to calm explanation, praise, and reassurance. Do not keep the appointment in a harsh tone.
7. Voice control and parent misunderstanding
Voice control is one of the techniques most likely to be misunderstood by parents. A parent who does not know the technique may think the dentist is angry or scolding the child. That can damage trust even if the dentist’s intention is safety.
This is why explanation matters. If a child is at risk of moving during a procedure, the parent can be told: “If I need your child to stop suddenly for safety, I may use a firmer voice for a moment. I am not shouting at them; I am helping them stay safe.”
That parent explanation is as important as the technique itself. A behavior guidance method that loses parent trust creates a new problem.
Parent-friendly explanation
“Most of the time I will speak gently and explain each step. If your child moves suddenly during something sharp or noisy, I may use a firm voice for a moment to keep them safe. It is not punishment.”
8. What Tell-Show-Do sounds like
Tell-Show-Do should use child-friendly language. Avoid words that create fear. Instead of “needle,” say “sleepy gel” or “sleepy drops” if that is consistent with your clinic style and honest enough for the child’s age. Instead of “drill,” say “tooth shower” or “tooth cleaner.”
The show step should be real but non-threatening. Let the child hear the suction, feel air on the finger, see the mirror, or watch water spray outside the mouth. Then do the same thing in the mouth without changing the plan unexpectedly.
This matters during procedures like space maintainer review after early primary molar loss. A child who understands the band, mirror, and cement-cleaning steps is less likely to panic during appliance checks.
9. What voice control should sound like
Voice control should sound controlled, not emotional. It may be slightly firmer, slower, lower, or more direct than normal speech. The message should be short: “Stop.” “Hands down.” “Open please.” “Look at me.”
Long lectures do not work during unsafe movement. The child needs a clear instruction, not a speech. After the child responds, praise the correct behavior and return to a calmer tone.
| Good voice control | Poor voice control | Why it matters |
|---|---|---|
| Brief, clear command | Long angry lecture | Children respond better to simple direction. |
| Professional tone | Humiliation or sarcasm | Respect and trust must be maintained. |
| Used for safety or redirection | Used to punish fear | Fear is not misbehavior. |
| Followed by praise when child cooperates | Continued harsh tone | The child needs a path back to success. |
| Explained to parent if needed | Parent shocked or confused | Parent trust protects the appointment. |
10. Consent and documentation
Behavior guidance is part of treatment planning. Parents should understand the general behavior approach, especially if the child is anxious or if more directive techniques may be needed.
For routine Tell-Show-Do, formal detailed documentation is usually simple: the child was managed with communication, demonstration, praise, and reassurance. For voice control, documentation should be clear if it was significant: why it was used, how the child responded, and whether the parent was informed.
Do not document defensively. Document clinically. The point is to show that the technique was used briefly, appropriately, and for the child’s safety or cooperation.
11. Special health care needs and communication limits
Children with special health care needs may need modified behavior guidance. Tell-Show-Do can still help, but the “tell” and “show” steps may need visual supports, shorter instructions, sensory adaptation, or caregiver input.
Voice control can be inappropriate or ineffective if the child has sensory sensitivity, communication difficulty, developmental delay, autism-related distress, hearing impairment, or trauma history. A firm voice may escalate rather than help.
In those cases, a better plan may include desensitization, visual scheduling, short visits, caregiver coaching, distraction, nitrous oxide, sedation assessment, or referral. The technique should fit the patient, not the dentist’s habit.
12. Pain control comes before behavior control
Do not use behavior guidance to push a child through pain. If the child is moving because anesthesia is inadequate, the answer is not stronger voice control. The answer is to stop, assess pain, and correct the anesthesia or treatment plan.
This is especially important in pulp therapy, where pain can be real and sudden. During primary molar pulpotomy, behavior guidance supports cooperation, but it does not replace adequate local anesthesia, isolation, and clinical judgment.
Do not miss this
If the child is reacting to pain, fix the pain. Do not label pain as bad behavior.
13. Tell-Show-Do during procedures
Tell-Show-Do is not only for the start of the appointment. It can be used in small cycles throughout treatment. Before suction, tell and show. Before air-water spray, tell and show. Before placing a rubber dam clamp, tell and show at a level the child can understand.
The child learns that your words predict what happens. This predictability builds trust. If you say “just a look” and then start treatment, the child learns not to trust the next explanation.
This is important in longer procedures such as stainless steel crown preparation, where there are many unfamiliar sounds and sensations.
14. Combining techniques
In real appointments, techniques are combined. Tell-Show-Do prepares the child. Positive reinforcement rewards the behavior you want. Distraction helps the child cope. Nonverbal communication guides attention. Voice control may briefly interrupt unsafe movement.
A strong answer does not present these techniques as isolated boxes. It describes a flexible behavior plan based on the child’s age, anxiety, treatment need, pain control, parent presence, and previous dental experience.
For example, a child receiving care for severe active caries may need several visits. The behavior plan should build trust across visits, not win one appointment by frightening the child.
15. When basic behavior guidance is not enough
Tell-Show-Do and voice control are basic techniques. Some children need more support. If the child has severe anxiety, very young age, extensive treatment needs, acute pain, special health care needs, or repeated failed visits, basic techniques may not be enough.
In those cases, consider staged care, desensitization, nitrous oxide, sedation assessment, general anesthesia planning, or specialist referral depending on the case and local standards. This is not failure. It is matching the treatment setting to the child’s needs.
This is similar to deciding whether a badly broken tooth needs pulp therapy or extraction. The correct plan is the one that is safe, realistic, and beneficial for that child.
Treatment plan failing because the child cannot cope?
Reassess the whole plan. The safest treatment may be a simpler procedure, staged care, referral, or advanced behavior guidance.
16. Common mistakes
| Mistake | Why it is risky | Better habit |
|---|---|---|
| Calling voice control “shouting” | Misrepresents the technique and sounds unprofessional. | Describe controlled voice modulation. |
| Using scary words in Tell-Show-Do | Increases anxiety before treatment starts. | Use honest, child-friendly language. |
| Using voice control for pain response | Pain is being mistaken for behavior. | Stop and reassess anesthesia or diagnosis. |
| Not explaining firm voice to parents | Parents may think the child is being scolded. | Explain safety-based redirection when appropriate. |
| Forcing basic techniques when they fail | Can traumatize the child and compromise care. | Escalate to suitable support or referral. |
17. OSCE answer
In an OSCE, do not list behavior techniques randomly. Compare the aim, timing, and safety of each technique.
Model answer
“Tell-Show-Do is a basic behavior guidance technique where I explain the procedure in developmentally appropriate language, demonstrate it in a non-threatening way, and then perform it as described. It reduces anxiety and builds cooperation. Voice control is different. It is a deliberate change in voice tone, volume, or pace to gain the child’s attention and direct behavior, especially when sudden movement could be unsafe. It should be brief, professional, and not confused with shouting or punishment. I would usually begin with Tell-Show-Do, positive reinforcement, and calm communication, then use voice control only if appropriate for the child and situation.”
18. FAQ
Is Tell-Show-Do suitable for every child?
It can be adapted for many children, but the explanation must match the child’s age, language, development, anxiety level, and communication ability.
Is voice control the same as yelling?
No. Voice control is controlled modulation of tone, volume, or pace. If the dentist is shouting in anger, that is not proper voice control.
Should parents be told about voice control?
Yes, especially if a firmer voice may be needed. Parent explanation prevents misunderstanding and protects trust.
What if the child is crying because of pain?
Stop and assess pain control. Behavior guidance should not be used to force treatment through inadequate anesthesia or untreated pain.
What comes after Tell-Show-Do fails?
Reassess why it failed. The child may need shorter visits, distraction, desensitization, nitrous oxide, sedation assessment, general anesthesia, or referral depending on the case.
