8 Best Water Flossers (Waterpiks) of 2021

Water flossers are handheld devices that spray water between your teeth in steady pulses. Like traditional flossing, water flossers remove plaque and food particles between your teeth. 

Water flossers that have the American Dental Association (ADA) Seal of Acceptance help prevent cavities, gingivitis, periodontal disease, and other oral health conditions. The ADA currently accepts Waterpik and Philips Water Flossers.

Benefits of ADA accepted water flossers over regular string floss:

  • Can remove more dental plaque between your teeth and along your gum line
  • Help prevent and reduce gingivitis between your teeth
  • Massage your gums, which can help improve gum health 
  • Convenient and quick cleaning
  • Ideal for people with limited dexterity (moving abilities) or arthritis  
  • Easy to clean between dental implants, dental bridges, braces, and other dental work

  • Compare positive and negative reviews on the products
  • Talk to company leaders to ensure their products are safe and effective
  • Look into costs to ensure customers are getting the best quality products at reasonable prices
  • Read research studies to compare the pros and cons of each product

Every piece of content is heavily reviewed before publication. All content on NewMouth is also medically reviewed by a licensed dentist, specifically any content where we recommend products. Our dentists are specifically instructed to flag any recommendations they don’t agree with. Any products that don’t meet their professional standards are removed.

Many of the products we recommend have the American Dental Association (ADA) Seal of Acceptance. These products are proven to be effective in preventing gum disease, cavities, and other oral health conditions.
