In recent years, there has been a new type of treatment called "blue light" teeth whitening, or "light activated" teeth whitening.  This works in basically the same way that laser treatments work at the dentist, but it is a bit scaled down and doesn't require as large of equipment.

In simple terms, they put a special cream on your teeth, and then you sit for a while with your mouth open and exposed to a special "blue light" (although not all are blue!).  The radiant light reacts with the cream on your teeth, and this in turn bleaches your teeth.

Some companies have even tried making "blue light home kits" so that you can try these treatments at home.  There is one product that has a small denture shaped light that you wear after you put the cream on your teeth.

This is a cool new way to whiten your teeth.  It gives you fairly professional results and generally doesn't cost as much as having a dentist do it.  Finding these home kits can be a little difficult though.  My personal recommendation is still just to brush regularly and try one of the free whitening products available online, such as Alta White.  You can find out more about this product, and other free teeth whitening trials in other posts on my blog.
