How do Crest Whitening Strips work?

Question

I'm thinking about buying Crest Whitening Strips and I have 2 questions...

1) How do they work?

2) Are they suitable for a 14 year old to use?

Thanks.

Answer 1

basically you just slide them onto your teeth according to the package and wait for about 10-15 minutes. usually after, i would brush my teeth because of the "slime."

for a 14 year old, it all depends. many times the gums can become very irritated and sensitive. that happened with me and it was a bit painful for a few days. it can go both ways, it really all depends on the person.

hope i helped a bit!
