so i had a patient who swore by nano hydroxyapatite toothpaste for her tooth sensitivity. what caught my attention was the specific type of nha she used - it had to be nano, not just hydroxyapatite on the label. apparently some types of nano-hydroxyapatite are more efficient than others.
i’ve seen hygienists test different brands and types of toothpaste, and the results vary. one thing that stood out was the importance of particle size - the smaller the particles, the better they penetrate the tooth enamel. has anyone else noticed a difference with nano hydroxyapatite toothpaste?
and what brands or types have you found to be most effective? i’m curious to know if there’s any real difference between the various products on the market.
