The Dentist's Recommendation: How Often to Replace Your Toothbrush
Originally Published 2 years ago — by CBS News
Dentist Dr. Kevin Sands recommends replacing your toothbrush every three to four months to ensure effective bristles and minimal bacteria accumulation. The American Dental Association advises replacing it sooner if the bristles are visibly matted or frayed. After recovering from an illness, it's best to start with a new toothbrush to eliminate lingering bacteria. To maintain toothbrush hygiene, rinse it with hot water after each use and store it in a clean, dry place without using caps or covers that can trap microbes. If sharing a bathroom, avoid contact between toothbrushes to prevent the spread of bacteria.
