My teeth are in good health and I take good care of them, yet I always get this plaque buildup no matter what I try.
I've tried different brushes, toothpastes, and flossing methods to no avail. Mouthwash is too harsh on my mouth and peels my skin off so I avoid that.
I haven't tried waterpicks or electric brushes yet. Did you? Did they work for you? Have you succeeded in preventing plaque and if so, how???
The skin inside my mouth yes.

That's the best reference I can find on a quick Google search, it even has images in case you wonder. I'm fine with toothpastes because I rinse thoroughly after brushing, but mouthwash needs no rinsing to be effective and after a week or so of regular use the inside of my mouth gets very irritated and sore.
