The American Dental Association recommends getting a new toothbrush every three months in order to avoid brushing your teeth with bristles that may contain bacteria. If you are using an electric toothbrush then you need to change the head every three months as well. With every scheduled cleaning Sachem Dental gives you a new toothbrush to replace your old one, as well as some sample toothpaste and floss.
It all depends on your usage, health and preferences. Before you brush again, ask yourself whether it is time for a new toothbrush. Replace toothbrushes every 3 to 4 months. Consider getting a new toothbrush sooner if you have been sick, especially if the toothbrush is stored close to other toothbrushes. When in doubt, look at the bristles. If they are frayed, they won't clean teeth as thoroughly.
