We all know flossing is important for dental hygiene, but it’s often challenging to commit to daily. As comedian Mitch Hedberg said, “People who smoke cigarettes say, ‘Man, you don’t know how hard it is to quit smoking.’ Yes, I do. It’s as hard as it is to start flossing.”

Water flossers, also called oral irrigators, can make flossing easier or more effective by removing the sticky film of plaque from teeth to prevent cavities. According to the American Dental Association (ADA), when used correctly, water flossing can reduce the risk of gingivitis, which is an early form of gum disease.

The Oral Breeze ShowerBreeze attaches to your existing showerhead, meaning you can only use it in the shower. Though this limits where you can use it, it also makes cleanup easier. The food particles, plaque, and water wash right down the shower drain, eliminating the need to clean your sink or mirror. Since it attaches to your showerhead, you never have to refill a reservoir tank.

The dimmer switch lets you adjust the pressure until you find your ideal setting.

The ShowerBreeze is made of chrome-plated brass. The company has installation instructions and videos online.

If you have trouble making time to floss, this could be a great option, since you can add a minute of water flossing to your regular shower routine.

This handheld water flosser is compact, cordless, and rechargeable. But its standout feature is the oscillating nozzle, which directs more water around and between the gums and teeth. It makes for a thorough clean with minimal effort. The nozzle tip is also small, so it works well in tight spaces or with orthodontics.

On the downside, the reservoir is small and you may need to refill halfway through flossing your entire mouth. There’s also no warranty offered, but the company does have a 30-day refund window if you decide it’s not a good fit.

Wondering what to look for in a water flosser? Here are some tips about features and other considerations.

  • Pressure settings: Look for multiple pressure settings, especially if you have sensitive gums or teeth. If you’re new to water flossing, it might take some time to adjust to the force of the water, so you want multiple options to choose from.
  • Cost: Keep your budget in mind when getting a water flosser. Don’t overspend on a product you might not end up using.
  • Size: Do you travel a lot? If so, you’ll want a lightweight flosser that fits easily in your carry-on bag. If you’re a homebody with a large bathroom countertop, a standing model with a large reservoir might be better for you. If you have troubles with dexterity, gripping, or hand pain, choose a lightweight, ergonomic model.
  • Warranty: Many flossers have a 90-day guarantee, meaning you can try it for up to 3 months and get your money back if it’s not for you. Look for a flosser with a warranty of at least 2 years and read the coverage details. Flossers aren’t cheap, and you want to make sure yours will last (or is easily replaceable if it breaks).
  • Ask around: If you still don’t know which option to go with, ask your friends, family, or dentist which products they prefer.

This type of oral health appliance uses water, pressure, and often pulsation to deliver a stream of water into the mouth. Aiming this targeted stream along the gum line and between the teeth can help remove food particles and bacteria that could contribute to plaque.

That makes a water flosser a good addition to regular brushing and flossing for healthy teeth and gums.

  1. Always point your flosser at the sink to test the stream before putting it in your mouth.
  2. For easy cleanup, use your water flosser in the shower (after making sure yours is shower-safe).
  3. Put the flosser inside your mouth and aim the water along your gum line and between your teeth.
  4. To reduce water splashing, close your lips before turning it on and while using the flosser.
  5. After flossing, make sure to rinse your mouth with water or mouthwash, and spit out any loosened food or plaque.

No matter how you choose to floss, it’s imperative that you do floss. The ADA strongly recommends you find at least one way to floss, whether that’s with dental tape, dental floss, water flossers, or floss picks. If water flossing isn’t for you, check out some alternatives below.

  • Waxed floss: Waxed floss is dental floss coated in wax, making it easier to glide between the teeth. It’s also more likely to be flavored, which can make it feel more refreshing and pleasant.
  • Dental tape: Also called ribbon tape, dental tape is similar to floss but is broader and flatter. Some people find tape easier to use than floss and like how it covers more tooth area than regular floss.
  • Flosser picks: If you find dental floss unwieldy or unpleasant, try flosser picks, which are plastic picks that are prethreaded with floss. You can grip the pick with your fingers and move it in between each of your teeth, scraping each tooth’s side as you pull it up.

How do water flossers work?

A small motor allows water to come out in a steady, powerful stream. This stream of pulsing, pressurized water has enough force to dislodge food particles stuck between teeth, and blast away plaque and stains. The water stream can get to hard-to-reach crevices that brushing alone cannot.

Are water flossers better than string floss?

This is a good question with an unclear answer. Water flossers with the ADA Seal of Acceptance are proven to remove plaque. They can also be easier for some people to use than dental floss. Water flossing may not be quite as effective as traditional flossing at removing plaque, but using both can be a good combo.

Can I use a water flosser instead of dental floss?

Water flossing isn’t considered an alternative to dental floss, but it can be an effective supplemental aid. Brushing your teeth, flossing with traditional floss, and flossing with water give you the most thorough at-home cleaning.

However, something is always better than nothing, so if you hate regular flossing but love water flossing, it’s better than not flossing at all. For a clearer answer for you, ask your dentist at your next cleaning.

What’s the difference between a Waterpik and flosser?

There’s no difference between a Waterpik and a water flosser. Waterpik is a brand of water flossers, but the name has become largely synonymous with the product as a whole.

Water flossers are a good alternative to traditional dental floss if you hate flossing, have orthodontic work, or are concerned about gum disease.
