Henry asked: I bought a Crest Whitestrips pack at Costco that came with Crest Whitestrips Premium Plus, and Crest Vivid White toothpaste. The normal pack of Premium Plus strips comes with enough strips for 10 days. This one however comes with extra strips to extend the whitening period to 14 days. Is it safe on your enamel to be using the higher strength Premium Plus strips for that long of a period?
Also, if you experience tooth sensitivity does that mean it may be harming your teeth and enamel? I can put up with any amount of sensitivity as long as I know I’m not damaging my teeth.
Thanks.
