TORONTO - Health Canada is alerting Canadians to safety problems that have been reported about "Spinbrush" brand powered toothbrushes.

The advisory comes two weeks after the Food and Drug Administration warned U.S. consumers that owners have reported parts flying off the Spinbrush brand products during use, resulting in chipped teeth and other injuries.

The toothbrushes are sold by Arm & Hammer but are made by Church & Dwight Co., Inc.; until 2009 they were sold as the Crest Spinbrush.

Health Canada says it has received no reports of injuries in Canada related to the use of these toothbrushes.

Church & Dwight Canada says consumers should replace their brush heads after three months of use, or when brushes are damaged or become loose.

The company also advises users to inspect brushes for loose parts, saying extended use, loose parts or excessive wear could lead to brush head breakage and possibly become a choking hazard.
