If you’re one of the 80% of men who don’t floss regularly because it’s annoying, a water flosser is the solution. Water flossers use a pressurized stream of water to blast food and bacteria from between teeth and below the gumline — no string required. Studies show they’re equally effective (some say better) at reducing gum disease compared to traditional floss.

How to Use a Water Flosser Properly
1. Fill the reservoir with warm water (more comfortable than cold). 2. Start on the lowest pressure setting and increase gradually. 3. Lean over the sink and place the tip in your mouth before turning on. 4. Aim at the gumline at a 90-degree angle. 5. Work along the gumline, pausing briefly between each tooth. 6. Do both the front and back of your teeth. Total time: 60-90 seconds. That’s it. Pro tip: Use before brushing, not after. This loosens debris that your toothbrush then cleans away.
Frequently Asked Questions
Can a water flosser replace regular flossing?
For most people, yes. Studies show water flossers are as effective as string floss for reducing gingivitis and plaque between teeth. Dentists increasingly recommend them as a valid alternative, especially if the alternative is not flossing at all. The best flossing method is the one you’ll actually do.
