Sensitive about Tartar Control

Lots of people have a problem with sensitive teeth. I've learned that the tartar control toothpastes can, for some, lead to this problem. Evidently there is another part of the teeth that we didn't learn about in school. Tartar control toothpastes strip this invisible layer (it's called salivary peliclle) off of your teeth and slows it's reformation. The tartar then doesn't build up as easily (at least in theory), but it causes some people's teeth to become sensitive. Most toothpaste boxes now hardly even mention that they are tartar control, It's just a given.
Seeing as how Fluoride is toxic and traditional toothpastes (chock full of sugar) haven't helped I'm giving them up for more natural alternatives.
