Thumb-sucking is a common form of self-soothing for many small children, who will usually outgrow it between ages 2 to 4. While the habit is generally harmless, it can impact a child’s teeth if done persistently. Find out more about the effects of thumb-sucking and when to contact your pediatric dentist for assistance below.

What Are the Effects of Thumb-Sucking on Teeth?

Thumb-sucking occurs before the loss of baby teeth. If a child still sucks their thumb after permanent teeth start to come in, it may affect the alignment of the teeth and the roof of the mouth. The intensity of the activity will determine the effect; frequent, prolonged, or intense sucking is the most potentially damaging.

How Can You Get Your Child to Stop?

Breaking the child from this habit can be difficult. Try these options first:

• Address the Root of the Behavior: Anxiety, sleep issues, or insecurity in certain situations may cause thumb-sucking, so observe when your child is most likely to do it and offer comfort. They may respond well to another self-soothing method, like hugging a stuffed animal.

• Praise: Each thumb-free moment is a win, so praise your child when they stop the behavior.

• Give Them Agency: If you have an older child who still sucks their thumb, explain why they need to stop and help them choose the method.

• Deter the Habit: Ask your pediatric dentist for a bitter-tasting medicine with which you can coat your child’s thumb to break the habit. Or you can bandage the thumb or put a sock on their hand, especially at night when the behavior may be automatic.
