I have found a simple but effective way to get rid of plaque naturally. I use facial cotton. What I do is to wet the facial cotton, wrap it around the forefinger, then with the facial cotton brush all the accessible area of the teeth. The plaque will be removed by the facial cotton. The surface of the teeth, which used to feel rough, will now feel smooth to the tongue, and the plaque will be transfered to the facial cotton which can be thrown away. When I was doing this, I had no cavities.
