The hard outer layer on the crown of your teeth is called enamel. You may have heard about it before, probably from your dentist or from dental product commercials, but how much do you know about tooth enamel? Erlanger, Kentucky dentist Dr. Darlene Sand Wall offers these fun facts about your teeth’s most important protector.
- Tooth enamel is the hardest tissue that the body produces–even harder than bone! It is also one of the hardest substances found on earth, second only to diamonds.
- Enamel only covers the crown (top) of your tooth that is visible above the gum line. Your tooth’s root is not protected by enamel and can become quickly infected if exposed by receding gums.
- Contrary to popular belief, enamel is not white; it is translucent. The white coloring of your tooth is derived from the inner part, known as the dentin. Enamel can stain, however, from food, dark colored beverages, coffee, and tobacco use. At your six-month dental checkup, Dr. Sand Wall will perform a thorough cleaning to remove stains and reduce your risk of permanent staining. (more…)
