Enamel

First off, what exactly is tooth enamel? Enamel is the thin outer covering of the tooth. Tooth enamel is a hard substance found in the shell of each of your teeth. Enamel is considered the hardest substance in the human body. It's even harder than your bones; however, it's also susceptible to acid and build-up of bacteria. It can dissolve or decay when exposed to these substances. Enamel helps protect your teeth from daily use such as chewing, biting, crunching, and grinding. Although enamel is a hard protector of teeth, it can chip and crack. Enamel also insulates the teeth from potentially painful temperatures and chemicals. Unlike a broken bone that can be repaired by the body, once a tooth chips or breaks, the damage is done forever. Because enamel has no living cells, the body cannot repair chipped or cracked enamel. The enamel around your teeth is very important because it protects teeth from damage and allows you to eat foods without hurting your teeth. As long as you take good care of your enamel, your teeth will continue to be protected for years to come.
