Benefits of Hydroxyapatite for Tooth Enamel?
What is tooth enamel? Why should you protect it, and how can you do this? Tooth enamel is the outer layer of your teeth. It is the hardest substance in the body and contains a high percentage of minerals, including hydroxyapatite. Taking good care of this part of your teeth is an excellent step towards overall dental health. So remember to avoid highly acidic and sugary foods and drinks. Be gentle when cleaning your teeth, as excessive or harsh toothbrushing can be harmful too. Luckily, you have a natural shield that protects your tooth enamel, saliva! Your saliva helps with remineralization, a continuous reparative process that builds and maintains tooth enamel.
Brushing with a toothpaste that contains active hydroxyapatite can assist with enamel restoration and remineralization too. Some toothpaste and mouthrinses contain a nanocrystal form of hydroxyapatite (nHA) or a zinc combination (Zn-HA). According to an article published in Materials, hydroxyapatite toothpaste can counteract the effects of sodas, energy drinks, and other acidic beverages. By forming a protective buffer on the enamel, HA/nHA can decrease mineral loss and tooth erosion.
