Q: Is a $6 toothbrush any better than 99-cent one?
Oz Says: They're really pretty similar, as long as you choose a brush with these three must-haves:
1. Soft or extra-soft bristles: Your instinct might be to pick tough fibers, thinking you'll get a more thorough clean, but that's going to have the opposite effect, explains Caren M. Barnes, a professor and dental product researcher at the University of Nebraska College of Dentistry. "Softer bristles are flexible enough to reach in between teeth, so they sweep away more food and plaque," she says.
2. The American Dental Association's Seal of Acceptance: Manufacturers apply for this, and it's awarded to products that have undergone rigorous testing to verify they're built to clean properly and don't contain bad-for-you chemicals. Plenty of cheaper models have the seal on their package.
3. Give it a three-month max: That's the longest you should use a brush — frayed bristles won't be sturdy enough to do their job. Change brushes with the seasons.
