If you are looking for a teeth whitening gel then you have a variety of options available to you. There are many ways to deliver the gel and different types of gels to choose from as well. Below I will look at some of the systems and give my opinions on how good they are.
One of the most popular systems out on the market today are teeth whitening strips. These strips have the gel already in them. The gel is pretty gentle on the teeth and the results are rather effective. The only problem I have experienced with the white strips, is that they tend to slip out of place a lot. You need to wear these strips for up to an hour a day, and when they are constantly slipping out of place this can turn out to be quite a hassle.
The earliest product out was the trays. Basically you would put the teeth whitening gel in the tray and wear it for a half an hour twice a day. In these early systems the gel tended to be quite harsh on the teeth. They do produce good results as far as whitening your teeth, but lots of people have complained that their teeth have become much more sensitive after using these trays. Other users have complained that the trays can be quite uncomfortable. This obviously is not good when you need to be wearing these trays for up to an hour every day.
The latest teeth whitening gel product that I have found is called teeth whiten tips. Basically they are like Q-Tips that come preloaded with the gel inside them. They are quite convenient because there are no uncomfortable trays to wear and it only takes minutes a day instead of an hour to whiten your teeth.
