Answer:

The average person should be swapping out for a new toothbrush every three to four months,” explains Dr. Sienna Palmer, DDS, dentist at Meridien Dental in Santa Monica, CA. “This is recommended to ensure that the bristles are still effective and bacteria accumulation on the toothbrush is minimal.”
