They are made out of mint
Yes they do. I have listerine whitening strips that are expired. There should be something on the box.
Yes, a toothbrush and toothpaste. The strips are not made for cleaning.
considering whitening strips contain chemicals there is nothing natural about them.
Crest Whitening Strips are used as a popular alternative for whitening teeth. The ingredients include: Water, Glycerine, Hydrogen Peroxide, Carbon 956, Sodium Hydroxide and Sodium Saccharine.
Yes, you can.
I like Crest Whitestrips Seals better
About 20 dollars to 40 dollars
I don't think this is ok, girls at that age are young enough to improve their teeth and using whitening strips isn't a good habit to start.
After you remove the teeth whitening strips there will be excess residue on your teeth left over form the gel from the whitening strips. As the whitening gel gets to work it foams up (which is the oxidation process that whitens your teeth) so it will spread out across your teeth. The best thing to do is to gently brush away the gel from your teeth using a soft toothbrush and your normal daily toothpaste - this will remove the left over whitening gel and freshen up your mouth.
The 5 Minute Whitening Gel works great, but so do the Crest White Strips. It's solely a matter of preference.
Their teeth will get whiter.
My dentist recommended them to me when I was eleven almost twelve I have yet to use them because they are fairly pricey. This may not be for everyone but I don't have any thing that would make me any different from other kids. Check with your dentist first. Usually a quick call does the trick. Hope I helped.
