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???
Also you don’t need to buy multiple electric brushes, the replacement heads often if not always comes with colored rings you can put on. You can just have a different head for each person that you swap when needed.
