†Forms a protective layer over the sensitive areas of sensitive teeth. Brush twice a day for lasting sensitivity protection. *Apply a pea-sized amount to a clean finger-tip and rub gently into each sensitive area (max twice per day) for 1 minute before brushing.
Tooth enamel is the hard, visible, outermost covering of your teeth. Enamel is translucent, giving teeth their sparkle, and depending on its thickness, it shows through the colour of the underlying dentine which varies from light yellow to a grey or blue-like white. It’s the hardest substance in the human body and contains a high percentage of minerals.
What Is Tooth Enamel Made Of?
95% Minerals Primarily calcium and phosphate, tightly bound in a repeating lattice in the form of crystallites.
99% inorganic substances - by comparison, bones are typically around 70% inorganic
Did you know?
Enamel has an average thickness of 2-3mm, yet it can effectively protect the sensitive inner layers of teeth from exposure to hot, cold and acidic foods that can lead to sensitivity. 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 it less well protected. If damage is left to progress, it can be lost altogether in certain areas, exposing the underlying dentine.
Repeated intake of acidic 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 and wine – can dissolve tooth enamel over time. This process is called acid erosion or erosive tooth wear.
