Are thumb sucking or pacifier habits harmful for my childs teeth?
Generally, sucking thumbs, fingers, or pacifiers will only become a problem if they are continued for a prolonged period of time. Most children stop these habits on their own, but sucking habits should definitely be discouraged by 3 years of age. If your child continues to suck thumbs or fingers after this age, a mouth appliance may be recommended to help stop the habit.
