I purchased this mouthwash to help with cavities since my dentist recommended I use something with floride. Within a week of regular use I lost all taste in my mouth. I didn't connect this to the mouthwash for about 3 more days until I stopped using it. Upon researching this online I also discovered other complaints of it turning teeth brown. I will not be using it again.

I started using this because my dentist recommended that I start using a mouthwash with fluoride in it. I wish I had never tried this. At first everything was okay. Then I started getting ugly brown staining on my teeth. Apparently, crest pro health has cetylpyridinium chloride in it that causes this staining. The dentist was able to remove the stains by cleaning it off, but that cost extra money as well. I switched mouthwashes and my smile is white again.
