DEAR DOCTOR K: I take good care of my teeth, brushing and flossing regularly. Do I still need to have regular dental checkups?
DEAR READER: Even if you brush your teeth three times a day and floss daily, regular checkups with a dental professional are a must. For most people, two checkups per year are enough. That's what I have. Routine visits usually include a professional cleaning, an exam and possibly X-rays.
