Yes. Sensodyne is worthless in my experience, but brushing with a toothpaste I bought in Japan to restore enamel really worked. It had very immediate effects and my teeth kept the protective enamel even after I ran out.

Yep that'll happen depending where you live.

Sensodyne has a bioglass (sometimes called hydroxyapatite, NOVAMIN, or Biomin) which is what you are describing however it's excluded from the Sensodyne sold in the US. The reason why is a long story [1] but if you want "good" Sensodyne you have to import it from literally anywhere else or buy a no-flouride biomin version (made by Dr. Collins who decided to go through the FDA process) in the US. Both are luckily pretty easy to get on Amazon however there's a bit of a markup.
