Using a hard-bristled toothbrush can harm
27 years experience
A hard-bristled toothbrush coupled with an aggressive brushing technique can cause irreversible damage to your gums. Use a soft toothbrush and gently brush your teeth at a 45-degree angle, in a circular motion. Using a back-and-forth, sawing motion causes the gums to recede, and can expose the root of the tooth, making teeth extremely sensitive.
