Our teeth are made from a mixture of materials. The outer enamel is very hard to protect the inside tooth but it can chip and wear away with age so we should brush our teeth gently. The dentine inside is not as hard as enamel and is where cavities usually grow bigger. If the cavity extends into the pulp, which contains nerves and blood vessels, a toothache will develop.
