I am recovering from bulimia. I really wanted to whiten my teeth because they looked yellowish due the acid that came up from my stomach. I have been using whitening toothpaste but I can’t see favorable result. My friend told me that hydrogen peroxide can be used to whiten teeth.
Has anyone used this before? How effective it is in the teeth? How often should I use it? I would look forward for your input. Thank you very much in advance.
