Should I be concerned about thumb sucking?

 

Thumb-sucking can cause problems for dental development. Most children stop sucking on thumbs, pacifiers or other objects on their own between two and four years of age. No harm is done to their teeth or jaws until permanent teeth start to erupt. Thumb sucking that persists beyond the eruption of the permanent teeth can cause problems with the proper growth of the mouth and tooth alignment. How intensely a child sucks on fingers or thumbs will determine whether or not dental problems may result. Children who rest their thumbs passively in their mouths are less likely to have difficulty than those who vigorously suck their thumbs.
