do NOT try this at home

Several months ago I decided to be proactive about my tooth and gum health by purchasing Crest Pro Health mouthwash. Both Dave and I have been using it regularly to help ward away gingivitis and bad breath. Unfortunately, I was doing more harm than good. I went to the dentist last week and was told I had bad staining on the backs of my teeth. They asked what kind of mouthwash I used, and when I reported Crest Pro Health, they told me to promptly throw it away and never use it again. The hygienest then proceded to scrape my teeth for 25 minutes in order to get all the staining (and enamel while she was at it) off. So if you have this product at home, get rid of it NOW! so much for my hollywood smile....
