Risks of crest white strips?!
Question:
Risks of crest white strips?
i used them before and they worked so well. Is there any risk to this product? It seems that it works...so there mustbe something wrong about it. What other whitening soloutions have you used?
Answers:
I've used this product myself off and on for a couple of years. I don't believe there is any risk to them, although I do notice a bit of sensitivity with very hot and very cold foods. I also use the Listerine Whitening and the Crest Whitening toothpaste.
