Nope. They just leach into spaces in the enamel structure and oxidize the materials causing the staining. No need to worry.Originally posted by tanwe461
Hi all! This might sound like a stupid question, but we have like tooth whitening solutions that you can apply directly to teeth...like gel or something like that...are these harmful to the enamel?
The Colgate liquid whitener actually has a tendency to rinse off in saliva before it can exert much whitening effect. I can't pull up the literature reference, but you might try looking. Whitening strips seem to be the best home whitening option currently available.Originally posted by tanwe461
thanks guys for the reply. i am not sure whether this product is available in the US, but Colgate just had this whitening solution where you literally paint on the tooth. a lot of patients asked me the credibility of it, and i think it's not that bad if it's by Colgate. but just wanted to check with you guys.
