Review (5/5): healthy & fresh oral hygiene
I read about these in a magazine and decided to try it because I noticed sometimes my breath was a little funky despite how well I flossed my teeth. I will say these worked quite well they're a little slow and just a little bit of hygiene peroxide is released each night but you should follow the directions for them to work properly overtime. i'm on my third rotation of purchases so I've seen results in my teeth being brighter!
