there are a set of things you can and shouldn t do with your teeth

Oral habits in children cause unbalanced pressures to the immature soft gums. As a result, these dislocate the position of teeth which in turn may become abnormal if these oral habits are continued for a long time. Some of the harmful oral habits that fall under this category are thumb sucking, lip sucking and tongue thrusting, and mouth breathing. Similarly, biting habits like nail-biting and lip biting have an adverse effect on the teeth and their supporting structure.
