I used BioMin F for about a year, and I think it did something, but I'm not sure I'm qualified to evaluate its effectiveness.

Unfortunately it isn't actually available where I live (US), and I had to buy it from Canada... from a shop that hasn't had stock for more than a year now. I've tried ordering from other countries, but haven't found anyone else who will ship to the US.

I've tried the "BioMin Restore" toothpaste that is available in the US, and I don't feel like it's doing much of anything, but... again, not sure I'm qualified to evaluate.

If you have sensitive teeth both nHAP and novamin toothpastes help a lot there. I've tried both. nHAP is easier to get in the USA, there are several brands, for some reason some go nuts over the imported ones from Japan.

		If you're going to use nHAP, get Apaguard from Japan. Their nHAP is rod shaped, not jagged. They were the first to make rod shaped nHAP and have been doing it for decades. It's not a great idea to introduce cheap/jagged nHAP into your mouth. Sharp nanoparticles tend to cause cancer.
