Ask HN: What is your experience with Nano-Hydroxyapatite toothpaste?

I have really bad tooth sensitivity and I recently learned about n-Ha toothpaste being a solid treatment for it (mainly the one Boka sells) The fact that n-Ha is the compound that enamel is made of seems really promising but I don’t know enough about it to know if it’ll work and it’s really hard to trust product reviews. Money is in short supply so I really want to make sure I’m not buying into a fad.

I know you all are not dentists or chemists (I’m assuming anyway), but we’ll have the same teeth, so if you happened to use it for a similar purpose and saw good results, I want to know about your experience.

Thank you all.
