Research indicates that thumb sucking increases the risk of crooked teeth in children. Most children stop sucking their thumbs by the time they are six years old.

Key takeaways:

•If the child sucks their thumb a lot and in the same position, the teeth can grow crooked.
•Thumb sucking can push the teeth forward, leading to protruding teeth.
•Your child could end up having an open bite. This is when the upper and lower teeth don’t align thus creating an open space.

Take your child to the dentist for regular checkups, and get advice about thumb-sucking.
