Are you one of those people who constantly wishes that their teeth were whiter? It can be quite difficult to keep your teeth white if you are constantly drinking coffee, smoking or drinking red wine. All of these and even more foods cause discoloration in your teeth that can be almost impossible to get rid of. You can use a home dental whitening kit, but most of them don’t really work as they are supposed to – and this is mostly because of the limitations that are set in legislation. FDA for example sets the limits for the maximal amount of bleaching agent that can be used in these kits in the US – some companies go lower than these limits to be safe, some have high quality factories where they can produce a whitener that is just at the limit and will give the best effects.

The problem with dental bleaching kits is that if there isn’t enough bleaching agent in it, it will not do anything. 14% of carbamide peroxide is the exact same amount that dentists use for whitening your teeth, and there is a big reason for this. It is the smallest amount that is still safe and will produce some results. Bleaching kits that have less peroxides in them don’t work even if you use more of them that is advised – the solution simply isn’t strong enough to even start the whitening process in your teeth.

Before you choose to use any home bleaching kit for your teeth, it is a good idea to visit your dentist and get a full check up done. At the same time you should ask how much a dentist will charge for teeth whitening, just to be sure that you are saving money doing it yourself – if you think that it is not expensive to have it done at the dentists, you should have a professional do it for you.
