A water flosser is an oral hygiene device that uses a stream of pulsating water to remove food particles, plaque, and bacteria from between teeth and under the gumline.

Use & Efficacy

WATERPIK water flossers effectively remove plaque and debris from between teeth and below the gumline, improving gum health and reducing the risk of gingivitis.

Yes, WATERPIK water flossers are effective in reducing plaque and improving gum health, as evidenced by various studies and dental professionals' endorsements.

Studies indicate that WATERPIK water flossers are effective in reducing plaque buildup and gingivitis, with some suggesting they may be more effective than string floss in certain aspects of oral hygiene.

While a WATERPIK water flosser can be an effective alternative, especially for those with braces or sensitive gums, dental professionals often recommend it as a complement to traditional string flossing rather than a complete replacement.

WATERPIK water flossers have been found to be very effective at removing plaque, with some studies suggesting they may be more efficient in certain cases due to their ability to reach difficult areas. Most dentists recommend supplementing the use of a WATERPIK water flosser with traditional string floss.

Yes, the stream of water can penetrate deep between teeth and below the gumline, areas that can be challenging for traditional floss to reach effectively.

Yes, by effectively removing plaque and bacteria from below the gumline, WATERPIK water flossers can help prevent the onset of gum disease and assist in managing existing conditions.

Water flossers are effective at removing plaque but cannot remove tartar; tartar removal requires professional dental cleaning.

You can water floss either before or after brushing.

Yes, we offer multiple tips designed to meet specific oral hygiene needs, focusing on deep cleaning and gentle gum stimulation to improve health. Review our Tips Guide for more information on tip options.

For best results, lean over a sink or waterproof surface and place the tip in your mouth before turning the device on. Start with the back teeth and work forward to front teeth, directing the flow of water along the gumline and pausing briefly between teeth. Continue until inside and outside of both upper and lower teeth have been cleaned. Experiment with different pressure settings and tip selections to optimize cleaning. Go to our How To Floss page to view an instruction video.

Daily use is recommended for optimal oral hygiene and to maximize the benefits for gum health and plaque removal.

Yes, although all you need for effectiveness is warm water, there are additives including certain types of mouthwash that are safe to use. Please consult your user manual for specific guidance to avoid damaging the unit. After use, rinse the unit by partially filling the reservoir with plain warm water and running it with the tip pointed into the sink. Do not use iodine, chlorine, hydrogen peroxide, or water insoluble essential oils in WATERPIK devices, as these may damage your device.
