Is cetylpyridinium chloride safe? i have mouth spray that has 0.075% in it and it says 2 sprays but i do 5 or more. is this bad? can i use everyday?

Use as directed...: It is relatively safe, but does have some side effects (i.e., brown stains between the teeth and on the surface of teeth, skin irritation/rash, nausea/vomiting, etc., etc.). It is is also found in some pesticides. Unless you are a physician and are changing the prescribed dose, you should use it only as rx'd by your doc or as instructed on the bottle...

Safe mouth spray: Cetylpyridinium chloride is a compound used in mouth washes, toothpastes, and lozenges to fight bacteria. It doesn't eradicate them all, as some are normal to be in your mouth. The spray can reduce gingivitis and reduce plaque. It is safe, even at 5 sprays a day. However, regular dental care is also needed to assure dental health. http://www.ncbi.nlm.nih.gov/pubmed/11505791.
