Enamel is the hardest substance in the body, but it can break easily. So be careful:
– Don’t chew on ice or popcorn kernels.
– Avoid tongue or lip piercing; it has been noted that piercing in the mouth may cause significant oral deformities and may even lead to tooth loss.
– Don’t bite your nails.
– Don’t chew on pens or pencils.
– Avoid opening stuff, like bottle caps or plastic packaging, with your teeth; in other words, don’t use your teeth as tools.
