Replacement Toothbrush by Sonishare are described on the description page. There are 4 replacement toothbrushes which are a primary color coded. These fit on my husband’s Braun Oral B as well as on my Sonic rechargeable toothbrush handles. These do a great job cleaning between the teeth with the yellow floss parts of the brush. Not to be used as a replacement for flossing, but to use a few times a day with normally brushing. You should replace your toothbrush every couple of months or after a major illness. These are a wonderful substitute for the more expensive replacement heads and work exactly the same. I received these for free in exchange for my honest review.
