Advantages of Using Bleaching Gel
One of the advantages of using bleaching gel to brighten teeth is the ease of use. Because you can use the gel in a tray, in a pen, or painted directly onto the teeth with a brush it makes it easy for people to apply the gel in whatever method works for them. Bleaching gel works in as little as 10 minutes, which makes it perfect for people who want to brighten their teeth before going out or going to work. Bleaching gel also is not as messy as some other types of tooth whitening products because it is a thick gel. But despite the advantages using bleaching gel is not always the best choice for tooth whitening.
Disadvantages of Using Bleaching Gel
Bleaching gel, like many other peroxide based tooth whiteners, doesn't dramatically whiten teeth. If your teeth have some minor staining or are just looking dull then a bleaching gel will make your teeth look whiter. But if your teeth are discolored or seriously stained the peroxide gel won't have enough power to dramatically whiten your teeth. Another disadvantage is that the gel has to stay on your teeth in order to work which means you can't eat, drink, or do anything that might loosen the gel from the teeth the entire time that you're wearing the gel. Using the gel everyday can weaken the enamel on your teeth and over time it can cause sensitivity or make any existing sensitivity worse.
