Are thumbsucking and pacifier habits harmful for a child’s teeth?

Thumb sucking is perfectly normal for infants; most stop by age 2. If your child does not, discourage it after age 4. Prolonged thumb sucking can create crowded, crooked teeth, or bite problems. Thumb and pacifier sucking habits will generally only become a problem if they go on for a very long period of time. Most children stop these habits on their own, but if they are still sucking their thumbs or fingers when the permanent teeth arrive, a mouth appliance may be recommended by Our dental team.
