If your child sucks their thumb, you’re most likely wondering if it can have an impact on their teeth. While thumb sucking is natural for young children, if they still do it consistently as they get older and grow teeth, it can begin to greatly impact their dental health.
Roof of the Mouth
Thumb sucking can greatly affect the palate, which is the roof of the mouth. The constant pressure from thumb sucking can cause great sensitivity and discomfort, and can also cause the roof of the mouth to curve more. This reduces the amount of space between the teeth on the left and right of the upper jaw. Excessively using cheek muscles also contributes to the narrowing of the roof of the mouth.
Risk of Illness
Children often don’t wash their hands as much as they should, which means more germs on their hands. When they put their thumb in their mouth, any germs then transfer, which then makes them extra susceptible to getting sick and developing infections. Even if they do wash their hands, constantly putting your fingers or hands in your mouth isn’t sanitary.
Bite Issues
Consistent thumb sucking often produces bite issues, such as overbites and underbites. It can also cause other bite issues such as the bottom teeth going inwards towards the back of the mouth, or an open bite where the top and bottom teeth don’t touch even when the mouth is closed. These bite issues can make chewing difficult or uncomfortable.
Changes in Jaw Shape
If a child sucks their thumb for long enough, it’s possible for them to experience changes in the shape of their jaw, which then leads to changing the shape of their teeth overall. This can cause lisps and speech impediments.
Breathing Issues
If your child suffers from jaw misalignment due to thumb sucking, it’s not uncommon for them to also experience breathing problems. Since thumb sucking can cause a higher, more narrow roof of the mouth, the sinus passages and overall nasal structure are then affected.
