Some people prefer water flossing to traditional string flossing—and that’s ok! It’s a bit better for the planet, since it uses a bit of water rather than nylon and wax. Water flossing is also preferable for people with orthodontic work (like those pesky permanent retainers) or those with crooked teeth. Below, some of our water pick picks, but here’s what to consider before getting one:

ADA-approved: The American Dental Association tests products for effectiveness, so look for a water flosser that’s ADA-approved for the best oral hygiene possible. Tip type: Whether you want a water flosser to fight plaque or need to deep clean under braces, the tip type you choose can help you get a sparkling smile. Tips come in a variety of styles: regular, orthodontic, plaque-fighting, periodontal, and toothbrush-style. They all provide unique cleaning power. Some water flossers also come with a variety of tip styles, so the whole family can share the flosser.Water pressure: If your teeth are sensitive, look water flosser that comes in a range of cleaning settings so you don’t risk painful flossing. Generally, a water pressure of 70 PSI is your best bet as it can remove up to 99.9 percent of plaque. If you have ultra-sensitive teeth, look for an option with lower pressure and work your way up.
