What are some cheap methods of teeth whitening?

Good evening. Man, any quick whitening methods are generally not safe. My wife and I decided to use the home whitening procedure with a special lamp. To get started, I would advise you to read the guide for philips zoom. In short, it is a process of chemical oxidation, due to which the pigmentation of tooth enamel is reduced. This results in a lighter shade of teeth. Just try it and you won't regret it. Good luck!

Thanks for the great answer mate, it's worth it.
