Faced with dozens of different products promising to make your teeth fresher, whiter and cavity-free, it’s no wonder you wander aimlessly down the toothpaste aisle. To help you pick wisely, we turned to the pros for the scoop on what ingredients to look for, whether gel or paste formulas are right for you and just how much you need to squeeze onto your brush. It’s never too late to get your pearly whites in tip-top shape, so read on to find out how!

1. It’s all about the fluoride.
With a host of ingredients in toothpaste, it’s easy to lose sight of what’s essential. But no matter what your individual needs are (i.e., tartar control, whitening, breath-freshening and so on), dental hygienists agree that fluoride is a must. According to the Academy of General Dentistry, brushing with fluoride toothpaste twice daily can reduce tooth decay by as much as 40 percent. “Even in areas where there is water fluoridation, the added fluoride in toothpaste has been shown to be very beneficial,” says Caryn Loftis-Solie, RDH, president of the American Dental Hygiene Association (ADHA).

2. Look for the seal of approval.
While it’s tempting to save some cash with a generic brand of toothpaste, you may actually be getting an ineffective—and potentially harmful—product. “You should always look for the ADA Seal when choosing a toothpaste,” says Clifford Whall, PhD, director of the American Dental Association (ADA) Seal of Acceptance Program. “Only those products have the scientific data to back up their claims and have been proven to meet our criteria for safety and effectiveness.” With 50-plus approved toothpastes on shelves, it’s easy to find a tube that’s right for you and your budget.
