Having your teeth whitening done at the dental clinic can be a very expensive affair since multiple treatments are necessary for teeth to be whitened to a satisfactory level. That’s why do-it-yourself kits using hydrogen peroxide teeth whitening are popular as they offer a budget alternative for whitening teeth. Both over the counter tooth whitening gels and those used by dentists are based on similar ingredients, namely peroxide-based gels that work on similar principals of causing a chemical reaction to teeth surface.

Tooth whitening gels are available in a variety of formats such as strips, teeth whitening trays and even whitening pens which offer a level of convenience that appeals to many since you don’t have to go through the trouble of fixing an appointment with the dentist, showing up and getting the teeth whitening treatment done which can take 2 hours of sitting in a chair.
