Sensodyne?

I just learned about this 5 mins ago and did some basic research. Here's what I found:

- Sensodyne Repair and Protect contains 'NovaMin' (possibly only in some markets; check the ingredients!)

- NovaMin is the brand name for calcium sodium phosphosilicate

- It reacts with saliva to form a physical layer of hydroxyapatite on your teeth

- This layer blocks the tubules that trigger pain from temperature and such

- It also supports remineralization (how exactly?)

I used to use sensodyne for cold-sensitive teeth, but they changed ingredients to include something I’m now allergic to. Or I recently developed an allergy to whatever their unchanged ingredients are.

I have yet to find a replacement for it.

  • nanohydroxyapatite helps a lot with sensitive teeth, you can even find some brands that also have fluoride in it if you're worried about the nonfluroide versions
