Teeth whitening at home

Yes, you perform
at home whitening. Over-the-counter
teeth whitening products can work very effectively for certain people and are sometimes all you need to make your smile a few shades whiter. Most of these whitening kits use hydrogen peroxide, just like the professional teeth whitening systems. The difference of course is that the kits made for home use has lower concentration of bleaching agent.
The main advantage of the over-the-counter tooth bleaching products is that they are cheap compared to the professional whitening systems. The over-the-counter teeth whitening kits cost anywhere between $7 and $50 (at the time of writing this article), which is very inexpensive compared to a couple of hundred dollars for a professional teeth whitening procedure supervised by dentist. Another advantage of the whitening solutions meant for home is the fact that they are available everywhere (just ask in your local drugstore) and you can start using them right away.
There are some disadvantages of using over-the-counter teeth whitening products, and it wouldn't be fair if don’t mention them here. The main drawback of using at home whitening systems is that you don’t get opinion from professional dentist if it’s OK to whiten your teeth. What I mean is that not all teeth can be whitened successfully. For example yellow colored teeth react best to whitening and it’s much harder to bleach darker teeth (brown or gray). Your dentist might advise you
not to whiten your teeth due to health reasons as well. Another drawback is that the at home whitening procedure is not
supervised by dentist.
