People who use Spinbrush powered toothbrushes should know that owners have reported parts flying off that resulted in chipped teeth and other injuries.

Health Canada said it has received one report of an adverse event related to battery-powered toothbrushes, but it did not result in an injury.

Last month, the U.S. Food and Drug Administration warned consumers that owners have reported parts flying off the Spinbrush brand products during use, resulting in chipped teeth and other injuries.

Church & Dwight Co., which manufacturers the Arm & Hammer and Crest "Spinbrush" brands, advises consumers to replace their brush heads:

  • After three months of use.
  • When brushes are damaged.
  • When brushes become loose.

Extended use, loose parts or excessive wear could lead to brush head breakage and possibly become a choking hazard, Health Canada said.

The manufacturer says people should inspect their brushes for loose parts before using them.

The Spinbrush line of powered toothbrushes are currently sold as the Arm & Hammer Spinbrush and until 2009 were sold as the Crest Spinbrush.
