    Shopping Guide for Best Oral Irrigators

    If you want to keep your gums healthy and your teeth white and strong through your entire lifetime, you need to practice good oral hygiene, each and every day. That means twice daily brushing and at least once per day flossing.

    Unfortunately, according to the American Dental Association, a surprisingly high percentage of adults don’t achieve that goal. In fact, an ADA survey found that only 40% of adults floss daily, and a shocking 20% never floss at all.

    While most dentists agree that oral irrigators – also called water flossers, or referred to by the brand name Waterpik – can’t entirely replace string floss, they are excellent as a supplement to regular dental hygiene. They’re certainly a superior alternative to doing nothing. In fact, water flossers have several advantages over string floss:

    • Oral irrigators are less likely to cause gum bleeding or irritation.
    • They’re excellent for cleaning around braces, bridges, or implants.
    • For those with arthritis or hand pain, they can be much easier to use than traditional floss.
    • Oral irrigators can often be more effective than string floss at removing debris and plaque from beneath the gum line.

    EXPERT TIP

    Water flossing with lukewarm water is a much more pleasant experience than with cold water, so remember to fill the tank accordingly.

    What is an Oral Irrigator?

    An oral irrigator, or water flosser, is a device that directs a forceful stream of water through a specialized tip and into the mouth.

    The force of the water dislodges and washes away plaque, bits of food, and bacteria from the gums and teeth.

    All water flossers have a reservoir to hold the water, and an electric motor to power the pump.

    Waterpik Aquarius Water Flosser

    Technology

    The Waterpik Aquarius Water Flosser provides an impressive assortment of functions to help owners attain the "perfect clean." A rotating knob with ten increments regulates water pressure. Users enjoy two-step "pulse modulation" technology; one step is for flossing, and the other is for gum massage to improve circulation. There's an on/off button for water flow on the hand unit, and a master on/off button for the pump on the base of the device. The one-minute timer and thirty-second pacing function help ensure a thorough cleaning job.

    Different Types of Oral Irrigators

    There are two basic types of water flosser: countertop and portable.

    Types

    Countertop oral irrigators

    As the name suggests, these sit on your bathroom counter and plug into an electrical outlet. They have a fairly large reservoir, typically holding enough water for 60 seconds of use or more. Most countertop units have a range of pressure settings, and some have flow control for the stream of water. Countertop models are the best choice if two or more people will be using the flosser.

    EXPERT TIP

    Hold your water flosser’s tip at a 90 degree angle to your teeth as you clean. Pause for a couple of seconds between teeth. This allows the jet of water to really work in between the teeth and below the gum line.

    Portable water flossers

    These are powered by batteries. Some have rechargeable batteries and come with a small base for recharging between cleaning sessions, while others operate with disposable batteries and are entirely self-contained. These devices are handy for travel, or in a very small bathroom, but don’t have as much power – or as many pressure settings – as countertop models. Their reservoir is much smaller, generally holding enough water for 30 to 45 seconds of use. Although you can switch tips to share a portable water flosser with other family members, these are generally best for just one or two people.

    Portable flossers can be found for as little as $15, ranging up to $40 for those with more features and higher water capacity. Countertop irrigators tend to cost $35 to $40.

    DID YOU KNOW?

    Water flossing requires less hand strength and manual dexterity than string flossing, so it’s a good choice for anyone with arthritis, reduced strength, loss of hand coordination, or similar conditions.

    What Features Should You Look For?

    For the most part, an oral irrigator is a simple device, but there are a few features that add extra value.

    • Reservoir Size

    The larger the reservoir, the longer the cleaning time before running out of water. For a thorough job, you generally need at least 45 seconds of waterpower, although one minute is the recommended flossing time and should be your daily goal.

    • Adjustable Pressure

    While portable water flossers tend to have only two or three pressure settings, some countertop models offer up to ten.

    Once each month, fill your water flosser’s reservoir with antiseptic mouthwash, then run the flosser into the sink until the reservoir is empty. This will kill any bacteria that might be lurking in the tubing or reservoir.
    • Flow Control

    This allows you to slow or stop the flow of water while adjusting the oral irrigator’s tip in your mouth.

    • Color-Coded Tips

    If you share your water flosser with family members, each person needs his or her own tip. Color-coding makes it easy to tell which tip belongs to which user.

    • Rotating Tip

    This feature allows you to rotate the tip as you work, making it much easier to reach the back of your mouth or the backs of your teeth.

    Oral irrigator tips should be replaced every three to six months, or sooner if the tip is bent, bitten, or cracked.

    • Water Pulse/Gum Massage

    This mode pulses the water flow, which stimulates gum tissue and promotes gum health.

    • Timer

    A sound, pause, or vibration prompts you to move to the next section of your mouth, and signals when the recommended one minute of flossing time is up.

    • Tip Variety

    Many oral irrigators come with a few different types of tips.

    • Waterproof

    These water flossers are portable devices made for use in the shower.

    • Sound Level

    Most countertop water flossers are rather noisy, but some units claim to be quieter than others.

    EXPERT TIP

    If sharing a water flosser with family members, make sure each person has his or her own tip, and flush the tubing before each use.

    Types of Tips

    All water flossers come with a standard tip, and some include a few specialized tips as well. While you can swap out your device’s tips with others from the same brand, you generally cannot fit a tip from a different brand onto a water flosser.

    There are quite a few different types of water flosser tips, each suited for a slightly different purpose. Some of the most common are:

    • Standard

    The basic tip that comes with just about every water flosser.

    • Orthodontic

    Designed to clean around braces and other orthodontic work. Typically, there is a very small brush at the end of the tip to help dislodge food and other particles.

    Waterpik Aquarius Water Flosser

    Features

    With its larger-than-average reservoir and multiple settings, the Waterpik Aquarius provides a solution for every oral irrigating situation. This is reinforced by a large selection of pik tips: three "classic" jets, an orthodontic tip, a pocket tip, a plaque seeker tip, and a toothbrush tip. Overall, owners are very positive about the Waterpik Aquarius. Reviewers frequently call out two very straightforward assessments: the Aquarius is easy to use, and the results are excellent.

    • Plaque Tip

    A small brush on the end of the tip reaches into otherwise hard-to-reach areas to remove plaque and food particles.

    • Deep Pocket

    These tips have a slightly pointed end, and are used to flush out gum pockets to help relieve periodontal disease.

    • Toothbrush Tip

    Lets you brush and water floss at the same time.

    • Tongue Cleaner

    Buildup of bacteria on the tongue is a common cause of bad breath. A tongue cleaner tip helps remove that buildup for fresher breath.

    Braces and other orthodontic appliances tend to harbor food particles, plaque, and bacteria. Daily use of a water flosser blasts these decay-causing substances from under and behind wires and orthodontic bands and posts.

    Tips for Using a Water Flosser

    While using your oral irrigator isn’t difficult, it does have a bit of a learning curve and can be somewhat messy in the beginning.

    1. Fill the reservoir with lukewarm water. If you’d like, you can add a small amount of mouthwash as well, but don’t go beyond a 1:1 mixture.

    2. Don’t turn on your water flosser until the tip is inside your mouth.

    3. Start with the pressure on the lowest setting. You can slowly increase the pressure, but test carefully to ensure you don’t irritate your gums.

    4. If using your oral irrigator over the sink, lean forward slightly, so water from your mouth hits the drain, not your pants.

    5. Close your lips around the flosser’s tip, leaving them just parted enough for the water to drain out of your mouth. This will prevent water from spraying onto your bathroom counters or mirror. You might need to practice a bit to get the hang of it, but this is key to not making a mess while you floss.

    6. Start with your back teeth and work your way forward, doing first the bottom and then the upper teeth.

    7. Aim the water flow between your teeth, focusing on the gum line.

    8. Total flossing time should be one minute: half spent on the bottom teeth, and half on top.
