Water flossing is effective and has been shown to be at least as effective, and in some cases more effective, than traditional string flossing for reducing dental plaque and improving gum health. Studies and systematic reviews report that water flossers remove plaque from hard-to-reach areas between teeth and under the gumline, reduce gum inflammation and bleeding, and are especially beneficial for people with braces, dental implants, or gum disease. Water flossers are gentler and easier to use, which can improve adherence to flossing compared to string flossing. However, while water flossing is effective, combining it with traditional flossing can offer the best overall oral hygiene.

Effectiveness Evidence

• A 2023 systematic review found water flossing is superior to dental floss in removing plaque from inaccessible areas between teeth and improving gum health.
• Clinical studies report greater reductions in plaque and gum bleeding using water flossers compared to string floss after short and longer-term use.
• Water flossers are effective at reducing signs of gingivitis and inflammation with regular daily use.
• They are particularly beneficial for people who find traditional flossing difficult or uncomfortable.

Practical Benefits

• Water flossers use a pressurized water stream to clean deep between teeth and below the gumline.
• They are gentler on gums and reduce discomfort and bleeding often caused by string floss.
• Ideal for people with braces, implants, crowns, arthritis, or limited dexterity.
• Can replace traditional floss if used daily, though some experts recommend using both methods.

Limitations

• Water flossers may not remove tartar buildup, which requires professional dental cleaning.
• Some minor plaque removal differences exist across studies, but overall water flossing is effective for plaque control and gum health.

In summary, water flossing is a highly effective and user-friendly method for interdental cleaning that can improve oral hygiene and gum health, making it a good alternative or complement to traditional flossing.
