Philips sonic tooth brush replacement bristles
Reviewed in Canada on July 6, 2021
these do not fit that well on the Philips toothbrush. They work, but certainly not as well as originals. A note, because they do not fit perfectly to the base of the toothbrush, I recommend removing the brush head at least once a week and clean the tooth brush base of all built up toothpaste. The batter charge will last much longer if you do this. Also, the replacement bristles are much flatter than the originals, creates a different feel when brushing.
