What Is Tooth Enamel?

Tooth enamel is the hard, white, visible, outermost covering of your teeth. It’s the hardest substance in the human body, yet once worn away it cannot regenerate and can lead to the dentine layer underneath being exposed, which is duller and yellow in its appearance. Therefore, it’s really important to protect your enamel today to help retain a healthy white smile.

Your saliva continually replenishes the minerals in enamel keeping it strong and protected throughout the day. Fluoride in toothpaste accelerates this process and strengthens your enamel further.

  1. Did you know? Enamel has an average thickness of 2-3mm, yet it is the hardest substance in the body and can effectively protect the sensitive inner layers of teeth
  2. Acids in your diet can weaken and thin your enamel over time which can lead to the yellower dentine layer showing through making the teeth appear yellow and dull.
  3. Since tooth enamel contains no living cells, it lacks the ability to regrow. Once it’s lost, it cannot regenerate—leaving the softer layer underneath vulnerable.

Acid in our food and drink is a leading cause of enamel wear. Many acidic foods and drinks that make up our everyday diets – like soft drinks, fruits and fruit juices, salad dressings and wine – can dissolve tooth enamel over time. This process is called acid erosion or erosive tooth wear, and approximately 1 in every 3 young adults is already showing signs of it.

Keeping enamel strong is important to maintaining healthy teeth. By taking simple steps every day, you can help protect your teeth from the effects of acid erosion.
