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.
Yes they do. I have listerine whitening strips that are expired. There should be something on the box.
considering whitening strips contain chemicals there is nothing natural about them.
It is recommended to avoid smoking after using whitening strips as smoking can stain teeth and counteract the whitening effects. It is best to wait at least 24 hours after using whitening strips before smoking to maximize the results.
They are made out of mint
There are two strips: one for top, one for bottom. You are just supposed to put them on (with the jelly side ON your teeth) and keep them on for...I think about fifteen minutes. Then, you just take them off and rinse your teeth with cold water.
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
I always take care of my teeth, and like to keep them white all the time. I highly suggest you buy whitening strips which can be found in any drugstore. I recommend crest white strips. I have used crest white strips a few times and after you're done, they leave your teeth extremely white. It also saves money, I mean going to a dentist to whiten teeth can cost hundreds even thousands. However whitening strips range from $20-$40, saves the money. And after that you can purchase whitening toothpaste to maintain the whiteness.
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.
Yes, a toothbrush and toothpaste. The strips are not made for cleaning.
