Brushing carefully several times every day? That’s great. But after a while, it’s time to keep up the tooth brushing, but replace the toothbrush.
Experts from the Academy of General Dentistry recommend that you change your toothbrush before the bristles become frayed and separated, or about every three to four months. "A good rule of thumb is to change your toothbrush when it is no longer spongy and flexible," says Dr. Alan Zweig, a fellow of the Academy of General Dentistry, and a practicing dentist in Los Angeles, CA.
