Review on 🦷 Oral B Braun Replacement Toothbrush Heads - 4 Pack Precision Clean Brush Heads for Professional Electric Toothbrush - Compatible with Oral-B 7000/Pro 1000/9600/5000/3000/8000 (4pack) by Stephanie Williams

Mold grows inside this brush head. There is a small hole in the head. As a result, it becomes moldy. It's pretty gross when it goes in your mouth. We wash and rinse the head after each use and dry it to allow the water to drain. However, this doesn't work and quite a bit of mold forms after each use. As a result, buying these brushes is not economical. Not easy to use as you keep trying to remove mold. The bristles are soft. But it's useless if you can't use attachments.
