At first the only types of kits available over the counter were the ones that included a mouth guard (tray) and a stain removing agent gel. With these kits you would need to put some of the gel into the tray and then it would be put over the teeth for a while to permit the stain removing agents to operate. Although the trays are constructed from rubber not like the ones that dentists use these over the counter kinds tend not to fit the shape of your mouth exactly. As a result you might discover that the whitening of your teeth might not be even.
Today, however, there is another whitening product on the market that will help you to obtain a lot brighter whiter teeth. These are the teeth whitening swabs. As you will almost immediately learn this is not only a much more inexpensive system of having teeth whitened but is also a lot simpler to use.
With this whitening kit you take the cotton swab that is already covered in a mixture and dip it into the jar of powder that has both a bleaching agent and polishing agent. Once coated in the powder it is simply a case of applying the mixture to your discolored teeth and allow the chemicals in the concentrate to do their job. Within a matter of seconds of putting on the mixture to your stained teeth you will begin to notice stains being whitened.
If you are concerned that you may put too much powder on to each swab, don't be. The fluid that each swab has comes with unique properties that it will know when it has absorbed the correct quantity of the powder from the jar.
When it comes to saving of these kits in your home they don't take up the same amount of space that the trays or many other bright teeth whitening kits do. And since they can sit on a regular shelf you ought to be able to remember to use them every day. Plus of course these whiteners don't leave the same kind of mess that those using gels do. You don't have to be concerned about cleaning out a teeth tray. Just merely put the swab in the trash when your finished with it.
