My sensitivity came after a dental filling was performed. After a couple of weeks of use I didn't see/feel a difference. I've heard of Biotene toothpaste before and have even tried it in the past. Also, it's not as minty as the various toothpastes that I've used, my mouth didn't feel clean after brushing. This paste may be beneficial to someone with extreme sensitivities who simply can't use other pastes because of ingredients.
