Thumb Sucking & Your Child’s Teeth: What to Know

Thumb sucking is a common habit among babies and young children. It can help them feel calm, comfortable, or secure, but if the habit continues as their permanent teeth begin to come in, it may affect their oral development.

Understanding how thumb sucking can impact your child's teeth can help you know when it's time to help them break the habit.

How Does Thumb Sucking Affect Your Child's Teeth?

The effects of thumb sucking can vary depending on how often your child sucks their thumb, how intensely they do it, and how long the habit continues. Some of the most common effects include:

1. Changes to Tooth Alignment

Frequent thumb sucking can put pressure on your child's developing teeth. Over time, this pressure may cause teeth to shift out of their proper positions, which can lead to alignment problems.

2. An Open Bite

One of the more common effects of prolonged thumb sucking is an open bite. This occurs when the upper and lower front teeth don't come together when your child's mouth is closed, which can affect their bite and how they chew.

3. Changes to the Roof of the Mouth

The pressure from a thumb or finger can affect the shape of the roof of your child's mouth. Prolonged thumb sucking may cause the palate to become narrower or more arched as your child's mouth develops.

4. Problems With the Bite

Thumb sucking can affect more than just the front teeth. It may contribute to other bite problems, including an overbite or crossbite, depending on the position and frequency of the habit.

5. Speech and Oral Development Concerns

Changes in tooth alignment and the shape of the mouth may sometimes affect the way a child speaks. In some cases, prolonged thumb sucking can contribute to difficulty producing certain sounds or other oral development concerns.

How to Help Your Child Stop Sucking Their Thumb

Helping your child stop sucking their thumb can take patience and encouragement. These strategies may help your child gradually break the habit:

• Offer positive encouragement. Praise your child when they go without sucking their thumb instead of scolding or punishing them when they do.

• Identify triggers. Pay attention to when your child tends to suck their thumb, such as when they're tired, bored, nervous, or falling asleep. Finding other ways to help them feel comfortable may make it easier to break the habit.

• Keep their hands busy. Give your child a toy, stuffed animal, activity, or another safe object to hold when they feel the urge to suck their thumb.

• Use gentle reminders. A simple, supportive reminder can help your child become more aware of the habit without making them feel embarrassed or upset.

• Create a reward system. Consider using a sticker chart or another small reward to celebrate periods when your child avoids thumb sucking.

• Talk with your child's dentist. If you're having trouble helping your child stop, our dental team can offer age-appropriate guidance and let you know if the habit is affecting their teeth or oral development.

• Be patient. Breaking a thumb sucking habit doesn't always happen overnight. Consistent support and encouragement can help your child make progress over time.
