Crest Night Effects for Teeth Whitening???

Question

is it any good? i mean wil it do any harm? will it take off the enamel?

Answer 1

No they are amazing.

Answer 2

No, they won't do any harm.  Just keep it off your gums and apply it only to your teeth.  They won't take off the enamel.

Don't work as well as Crest White Strips and certainly no where near as good as a dentist prescribed home bleaching system or an in office bleaching procedure.

Answer 3

I heard that they make your teeth really sensitive.

They made my sisters teeth sensitive.
