Have you ever wondered what makes up a tooth? Each part of a tooth has unique functions and properties. Aetna's Simple Steps to Better Dental Health lists major parts of tooth anatomy, including enamel, dentin, cementum, root(s) and the root canal chamber(s) inside the tooth. Damaged teeth, especially teeth with cracked or eroded enamel, are very susceptible to cavities.

This can affect the appearance of your teeth and open the door for harmful bacteria that cause cavities. How Do Stomach Problems Affect My Teeth? Your stomach produces natural acids that help your body digest food. Sometimes, these acids travel up the throat and into the mouth, especially after a large meal. Ordinarily, our saliva rebalances the acid levels in our mouth and everything’s fine.  But for those who suffer from   gastroesophageal reflux , also known as acid reflux or GERD, gastric acids reach the mouth throughout the day.
