What is Dental Enamel?

Dental enamel is the outermost layer of the tooth, which covers the crown of the tooth and protects it from damage. Here are some facts about dental enamel:

  1. Dental enamel is the hardest substance in the human body, even stronger than bone.

  2. Enamel is made up of mostly calcium and phosphate minerals, and it also contains trace amounts of other minerals like fluoride.

  3. Enamel is not alive and cannot regenerate itself once it’s been damaged.

  4. Tooth decay and erosion can damage enamel over time, leading to sensitivity and discolouration.

  5. Enamel is translucent and allows the colour of the underlying dentine to show through, which is what gives teeth their unique colour.

  6. Enamel is also responsible for protecting teeth from temperature changes and acidic foods.

  7. Enamel is only found on the visible part of the tooth, as the roots of the teeth are covered by a different material called cementum.

  8. Enamel is thicker on the biting surfaces of teeth, where it is subjected to more wear and tear.

  9. Enamel is affected by dental treatments like teeth whitening and braces, as well as habits like teeth grinding and clenching.

  10. Proper oral hygiene, including brushing and flossing regularly, can help protect enamel and prevent damage.
