Habits like thumb and finger sucking are very common in children under the age of 4. Most children stop these habits on their own between the ages of 2-4. However, if this habit persists, it can damage the teeth and jaw, causing horizontal overlap of the front teeth, open bites, and crossbites. It also can also result in constant pressure from the tongue, forcing teeth out of alignment.
There are many oral appliances available to help break the habit of thumb sucking and tongue thrusting. Our dentists can also teach you exercises you and your child can do at home to break these habits.
