US-based personal and oral care company Water Pik has issued a voluntarily recall of its Sonic-Fusion flossing toothbrush due to concerns that the charging base may overheat.

The company has taken this decision after receiving consumer reports of product malfunctioning in the US. Overheating may cause localised melting and sparking, which could cause fire, shock and burns.

The recall covers around 3,800 units and is applicable only to Sonic-Fusion products. Other Waterpik brand flossers and toothbrushes are not affected.

“Overheating may cause localised melting and sparking, which could cause fire, shock and burns.”

The products under the recall were distributed from June 2017 to June 2018 across the US and Canada. They were sold to professional educators, key opinion leaders, trade show customers and limited direct online sales.

Water Pik is a wholly owned subsidiary of Church & Dwight and offers personal and oral health care products. It sells products such as Waterpik Water Flosser, shower heads, and Sonic-Fusion flossing toothbrush at retailers, wholesalers, contractors and online.

In May this year, Waterpik launched a new flossing toothbrush called Waterpik Sonic-Fusion, which is a one-step oral care flosser developed to improve gum health and remove plaque.

It was designed by combining the technologies used in Waterpik Water Flosser and Sonic Toothbrush.
