Can thumb sucking damage my child's teeth?

Thumb sucking is a normal, soothing reflex for babies and young children. However, as permanent teeth come in, continued thumb sucking may cause improper tooth alignment. Different factors determine if dental problems will occur resulting from thumb sucking, including how often your child sucks his or her thumb, how long they've been sucking their thumb, and how much force the child uses. Children should stop sucking their thumb by the time their permanent teeth come in -- usually around six or seven years of age.

Dr. Dantini recommends that positive feedback, such as praise or small rewards be given to encourage children to stop sucking their thumb. Negative reinforcement or constant nagging can have the opposite effect by making children more self-conscious and pushing them to suck their thumb more. As a last resort, Dr. Dantini can recommend an appliance be placed in the child's mouth, which serves as a reminder and a deterrent against thumb sucking. Parents should keep in mind that thumb sucking during childhood is normal and children will likely give up the habit when they are ready.
