Q: My problem is that I am allergic to tooth paste. Even if I use tooth powder my gums become painful and I develop mouth ulcers. How do I keep my teeth clean?

A:Allergy to tooth paste is rather rare. You may use good quality tooth powder(fine) with supersoft brush. You may also use mouth washes and dental floss to keep your mouth clean. You need to be examined to assess the situation. I am personally interested in your rather rare case and would like to see you and suggest accordingly.
