Demineralization and Remineralization

A tooth is made up of enamel, dentine, and the pulp. Enamel is the hardest part of the body, even harder than any bone in your body. This is because enamel is made up of 90% inorganic matter, consisting mainly of hydroxyapatite crystals, which are essentially made up of calcium and phosphate.

After meals, the bacteria in the mouth will break down sugar or carbohydrate left on teeth surface, producing acids which will then cause demineralization of the teeth surface, depleting it of calcium and phosphate. This process starts in enamel, and can progress to the dentine and eventually pulp, causing pulpitis. Continue reading
