Is hydroxyapatite being used for dental procedure in dentistry?

Answer 1

Hydroxyapatite is the material of which the enamel of your teeth is naturally made. Whenever a dentist drills your teeth, he's removing hydroxyapatite.

Fluoride treatments change the surface hydroxyapatite to fluorapatite, which is harder and more resitant to the acids generated by the bacteria in your mouth, thus it is more resistant to cavities. That's why fluoride in your water and toothpaste, and fluoride treatments have improved dental health so dramatically.

But the materials now being used in dentistry for reconstructive work are UV-cured ceramics and polymers, which are more easily shaped and placed than hydroxyapatite.

Answer 2

Yes. It may be used under a crown to replace removed diseased material.
