I'm currently using Elmex Sensitive Professional. It's apparently using arginine as its active ingredient. Although I don't know which ingredient in here it is that is actually in charge of numbing the pain. I know I've dabble with some other one as well but I have no idea what it had.

I did find Meridol and Sensodyne Rapid Relief toothpastes listed on a national pharmacy's website that apparently contain stannous fluoride, so maybe I'll have to try those out at some point. I don't think I've ever tried either.

Doesn't pretty much all toothpaste have that? Unless its kid's toothpaste or something specifically for people who are avoiding flouride.

Stannous as in tin (SnF2). Other fluoride toothpastes often use sodium fluoride or sodium monofluorophosphate. Stannous fluoride is slightly more likely to stain your teeth.

No they don't. You have to look for it. Crest and Colgate both have versions, the stannous has additional bacteria killing properties and filling in porous teeth as well that the potassium fluoride doesn't have. Plenty of research available online

No they don’t all have it. Stannous fluoride is different than whatever the regular fluoride is. I don’t know the details, I just know my dental hygienist recommended I try it, and it actually helped, which I wasn’t expecting.
