Always Be Cautious When Using Strips
Well imagine you’re painting a fence, and you just slapped paint on the outside, without taking the time to paint in the grooves between each wooden board. That fence would look pretty funny wouldn’t it? Nicely painted on the outside, but in the grooves between each wooden board, still dark and dingy, with all of the old paint showing. When you use teeth whitening strips on how to get white teeth, the same thing can easily happen to your teeth if you’re not careful. The whiter your teeth become, the more pronounced those dingy cracks seem! Eventually it can end up looking like you have small gaps between your teeth. Definitely not the desired result.
