How do you actually see plaque? I feel like I wouldn't be able to tell the difference if I got an electric toothbrush. Are you saying it actually makes your teeth look whiter?

I don’t think he can see it. But you know all that scraping the dentist does when you visit? That’s plaque. If you floss and use an electric toothbrush you’re in and out of a dental checkup in half the time.. with very little scraping.
