Query: Health Hazard

I purchased "Waterpik Ultra Dental Jet 100WP" in Sept. I used the small toothbrush that came w/it one time when 1st got it, put it aside, then several weeks later I decided to use it again..As I used it The small bristles came out in my mouth, the toothbrush had broken into 2 pieces,one large piece & one small section. I was concerned that was a definite HEALTH HAZARD, I emailed the company with my concerns they didn't respond so I called the company spoke to a Secretary she said will pass it along to her superior "if he is concerned he will contact me" He NEVER returned my call I would NOT/do-NOT recommend this product & to add to that it leaks. Am satisified that it does preform well but the health hazard & lack of concern of the company bigwig bothers me greatly.
