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.
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.
Fyi apagard premio has a 5-6% concentration, you ideally want 10%. That's what's been shown to be most effective in clinical trials, Apagard Royal has 10% but you can find similar concentrations cheaper from other brands.
