Episode #35: Does Size Matter?

Ask the Dentist with Dr. Mark Burhenne

When NASA noticed astronauts were losing essential minerals in space, they started prescribing hydroxyapatite supplementation. A Japanese company picked up on this, and in the 1970s released a commercial toothpaste containing hydroxyapatite. Recently, a toothpaste brand in the USA has also jumped on the bandwagon, and today Dr. B answers two questions about why this is a great prospect! Tune in to hear how hydroxyapatite works on teeth (and bones), why it’s better than fluoride, and where you can find it. Dr. B breaks down complicated chemistry into a simple explanation that makes the benefits of hydroxyapatite clear. From whether nano- or micro-particles are better, to how the state of the mouth affects its efficacy, you don’t want to miss out on this educational episode!
