Crest Pro Health has very harmful side effects in your mouth. I have been using this toothpaste for about a week and I have noticed skin inside of my mouth sloughing off everytime I brush. I thought in the begining that it was a good thing until I started suffering inflamation and swelling of my tongue. As a result I have been having trouble eating for the past few days. I have researched online for similar complaints and found over 500 of reviews of the product. P&G is aware of its side effects but will do nothing to take them off the shelves.  This product contains sodium hexametaphosphate and its side effect is severe irritaion of skin. P&G claims that this chemical is suppose to slough off your skin inside your mouth but they don't consider the fact that it is also causing dental pain. If we don't nip this in the bud there will be more products like this in the future. All they care about is making money. This is a very bad example of ethics and corporate social responsibility.
