Review on 🦷 Whitening Therapy Charcoal Toothbrush by Oral-B, Medium - 2ct by Heidi Davis

They work great! I originally bought these when my local Costco had them on sale/sale and now they don't seem to have them anymore (they have other Oral-B toothbrushes but no charcoal). After using them for 3 months I went to my dentist for regular scheduled cleanings. They noticed that I had a lot less plaque than usual and that I didn't have to brush much. Since Costco doesn't seem to sell them anymore, I bought a few more here, although the prices are significantly higher.
