Thumb-sucking is a behavior almost every infant and toddler practices. If your child sucks their thumb, fingers, or a pacifier, you may be wondering about the dental repercussions. Here, the pediatric dentists at Pedodontic Associates on Oahu and Maui, HI, explain why kids suck their thumbs and what you should do about it. 

Why Do Children Suck Their Thumbs?

Sucking is a natural reflex that starts when an infant is in the womb. Children typically suck pacifiers or thumbs as a coping mechanism to calm them in times of insecurity or stress. Because it is relaxing, it can also help them go to sleep. Most children stop sucking on their own between the ages of two and four. When they enter preschool or kindergarten, other children may pressure them to stop if they have not already done so. 

What Are the Effects?

Sucking on a pacifier or thumb too vigorously or for a prolonged period can have detrimental effects on children over the age of three. The most prominent risk occurs for those who suck after the age of four. At that time, they can start to permanently damage the teeth, jaw, and roof of the mouth.

If your child is still sucking after age three, discourage the behavior gently. Don’t use negative reinforcement since this will only exacerbate their feelings of insecurity and trigger more thumb-sucking. Instead, use a reward system to encourage them to quit. You can also place a bandage, glove, or sock on the hand to remind them not to do it.
