The ADA describes "whitening" as any process that will make teeth appear whiter, using one of two ways. A product can bleach the tooth, changing the natural tooth color. Most teeth whitening products use carbamide peroxide or hydrogen peroxide.
Many products currently on the market promise whiter, brighter teeth. The American Dental Association (ADA) says that if you are a candidate for a whitening procedure, your dentist may suggest a procedure that can be done in a dental office. Other options include at-home products, which your dentist may give you or you can purchase over the counter. We caution you about the incorrect use of such over-the-counter products. They are sometimes too abrasive and can damage the teeth upon extended use.
In-office Whitening: The dentist will use a whitening product on your teeth. It usually needs one to two visit.
Take home Whitening: This option involves using a custom-made tray from the dentist that can be worn comfortably while you are awake or sleeping. The tray is so thin that you should even be able to talk and work while wearing it.
Gum irritation and increased tooth sensitivity are the most common side effects of teeth whitening based on the duration of use.
