Any kind of bleaching treatment works by lightening the color of your teeth. Some products work on the principle of abrasion, like whitening toothpaste, but mostly, bleaching agents are used, which contain carbamide or hydrogen peroxide.
We looked into one of the best teeth whitening procedures to see how process is undergone step-by-step. Dentist begins by placing special tray, filled with whitening gel, in your mouth, firmly adjusting it to fit the shape of your teeth perfectly. To activate the gel and speed up the process, heat or combination of heat and light is used.
This will last for about 20 minutes and it will be repeated two more times. Sometimes you will need to pay one or two more visits for final effects to take place. At your first appointment, dentist will make molds of your teeth and produce mouth tray, which will be used for second and third treatment as well.
You will usually need to continue teeth whitening at your home with bleaching gel and trays given by your dentist. You will apply bleach on your teeth for half an hour once a week for about one month. Some of the newer solutions can stay on your teeth overnight and can deliver results within a week or two.
Majority of people will see satisfactory results undergoing teeth whitening at the dentist. Most common side effects are increased sensitivity of the teeth, which will last few more days after the treatment, and irritations of the soft tissue of the mouth. The results of whitening will last from 3 to 5 years; afterwards you will most likely need to go for another treatment again. If you refrain from repeating the same habits that caused staining of your teeth in the first place, you might extent the need for another treatment for few more years.
