Is thumb sucking a problem for dental health?

Thumb sucking is normal for infants and most negative effects on their dentition will be reversed as long as your child stops the habit before his/her third birthday. Thumb sucking if continued could lead to severe bite problems as your child gets older. If given the option we recommend giving your child the pacifier rather than allowing him/her to suck their thumb as this habit can be stopped much easier once the parent and child are ready.
