Water Pik Inc. might just have the hottest toothbrush in town — but not in a good way.

This month, Water Pik Inc. voluntarily recalled its Sonic-Fusion water flosser/toothbrush amid concerns that the charging base could overheat and possibly cause a fire.

In May, this product earned the ADA Seal of Acceptance after meeting all program requirements for toothbrushes and for powered interdental cleaners. The ADA Council on Scientific Affairs accepted the product, noting it is safe and has shown efficacy for removing plaque along the gum line and between teeth and helping to prevent and reduce gingivitis.

Water Pik Inc. issued a voluntary recall after receiving reports of the product malfunctioning from some U.S. customers, according to the Food and Drug Administration. The toothbrush base may overheat with localized melting and sparking, possibly causing fire, shock or burns, Water Pik says.

The electric toothbrushes/water flossers, which were sold in all U.S. states and Canada, were distributed between June 2017 and June 2018, according to company records. The products were limited to professional educators, key opinion leaders, trade show customers and limited direct online sales.

Water Pik asserts that there have been no reported injuries attributed to the problem. If consumers have had any adverse reactions, they can contact the FDA's MedWatch Adverse Event Reporting program.

Water Pik plans to correct the problem and then produce and sell the product again, according to the company. It will continue to have the ADA Seal.

For more than 125 years, the ADA has helped consumers identify safe and effective dental products. As early as 1866, an ADA committee prepared a statement on toothpaste that questioned whether extravagant marketing claims were "an imposition on the public." At present, more than 200 over-the-counter dental products have the ADA Seal.

Seal product submissions must include results from clinical and/or laboratory studies that demonstrate safety and efficacy according to product category requirements developed by the ADA Council on Scientific Affairs.
