I just started using something a few weeks ago called Tooth Soap and have really been impressed so far. I've noticed improvements in my gums, which had receded, and are now starting to come back. I'm not sure if it can help remineralize your tooth though. It's all natural too (coconut, olive, palm oils and essential oil). Somebody else on Curezone posted about it a while back and was getting really good results, so I thought I would give it a try and am glad that I did.
