“I brush twice a day. Why do I still get tartar?”
Usually because of where it forms, not how often you brush. The most common spot I see is behind the lower front teeth, close to where saliva enters the mouth, and that’s exactly where a brush tends to skim past. I’ll show you the area with a mirror and angle the brush with you, so you can feel the difference before you leave.
