The first brush I used from this pack was the C3 plaque control head . The bristles started falling out after two weeks of use. The bristles fell out of my mouth while brushing, starting with the top bristle. The whole round bristle base comes out so it doesn't wear out the glue used. I switched to the second head - G3 Gum Care - hoping the problem with the first head was an accident. After three weeks of use, a bristle fell out while cleaning today. Since 2003 I have been using Sonicare toothbrushes as my main toothbrush 2-3 times a day. This is the first time I've had bristles fall out of my toothbrush heads.
