We must take care of our teeth because they cannot be replaced.

A tooth consists of different parts:
external or crown — the part we see — and internal or root, the part we cannot see because it is housed in the bone of the jaws.

The enamel is the outermost layer of the crown. This part is very hard — even harder than bone. Beneath the enamel lies the dentine, which is not so hard, and beneath the dentine we find the dental pulp, which is sensitive to hot and cold foods, sweets or acids.
