But if you really want to see the biggest selection of teeth whitening products, then you have to go online.  Amazon is one of the biggest online retailers in the world and has hundreds of different whitening products to choose from.  Here are a few of the top selling products, but you can click on them to go to the Amazon website and check out everything for yourself.  Enjoy the variety!

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.

"Did you have any cavities?" we asked.

She said that the dentists told her she didn't have any cavities and her teeth were in great condition.  But...they suggested that she get her teeth whitened since they are naturally not that white.  Some people just naturally have whiter teeth than other people.

My sister and her husband then discussed some options.  At first he said she was fine the way she is, but she really wanted them whitened.  Then he said that they couldn't afford to get professional whitening from the dentist (what her dentist recommended).

After sitting there for a while it suddenly dawned on me that she could try one of the free teeth whitening products available online.  After all, I made this blog to tell people about all the great offers online, so I thought I should share the news with her too.

If you are reading this, you can get free products online too.  Although they are just short trial supplies, free samples don't get much better than that price, and even if it is just a small trial supply, it should still be enough to help whiten your teeth.

One of my current favorite free trial offers is called Alta White.  You can read more about it here on my blog and get a free trial supply for yourself to try it out.
