To understand why exposed dentine is a challenge to be solved, here's a mini-lesson on teeth:
- Enamel is the outer layer of each tooth. It's sort of a superhero since enamel is the hardest substance in our entire bodies and helps protect us from tooth sensitivity. Yay for enamel!
- Directly beneath enamel is the dentine layer. Though considerably softer than enamel, it supports your tooth's structure. (Hurray, dentine!) Dentine contains thousands of microscopic tubules with nerve endings connecting directly to the inner pulp of the tooth.
- Dental pulp contains the nerve fibre that interprets everything as pain. Yikes!
If your enamel wears away, exposing your dentine, then cold, heat, pressure, or almost anything can cause sensitivity. To learn how to prevent exposed dentine, first be aware of the causes. If you already have exposed dentine, know what treatments are at the ready.
