I tend to drink coffee frequently because I like it, but I hear that using a straw prevents staining, though it's not always easy to do so every time. Anyway, for various reasons, some parts of my teeth are yellow while others are not, so the color isn't uniform, and I'm considering teeth whitening. Since no one around me has had teeth whitening done, I have no one to ask. If anyone has done it, please tell me about any side effects or benefits. Thanks!
