Can you tell me more about nanohydroxyapatite?

Great question! Hydroxyapatite is a naturally occurring form of the mineral calcium apatite—calcium, phosphorous, and oxygen—that grows in hexagonal crystals. Hydroxyapatite is simply a form of the calcium mineral that your body can use to repair itself. Its use in dentistry has led to better preventive care and more successful treatment of dental disease.

is there anything without sodium lauryl sulfate?
