Yes, if you are using the brush with hard bristles. “Hard bristles may cause gum tissue to pull back from teeth, which can expose the tooth root and lead to increased sensitivity to heat, cold or certain foods and drinks.”(American Dental Association). Always choose soft or very soft bristle brush, and do not brush in back-and-forth motion. Select the brush that can easily fit in your mouth, it should brush one to two teeth at a time. Bigger is not always better!
