DO NOT USE CREST PRO-HEALTH MOUTHWASH
There are some very annoying side effects that this shit can do. It can not only stain your teeth but it can alter your sense of taste. My teeth are not stained but my sense of taste is gone for now. I cannot eat because I can't taste anything which sucks. I threw out that mouth wash and I'm going to go back to Listerine. Slowly I am starting to get my sense of taste back but holy crap I do not want to go through with this again. I can see why so many people are bitching about it on the internet. Ugh, if only I had looked this up before I would never have purchased it.
