What is tooth whitening?

It's a bleaching process that lightens discolorations of enamel and dentin. The system uses a mild solution retained in a custom-fitted tray that is worn over your teeth.

What causes tooth discoloration?

There are many causes. The most common include aging, consumption of staining substances (coffee, tea, colas, tobacco), trauma, nerve degeneration, and old restorations. During tooth formation, consumption of tetracycline or excessive fluoride may also cause tooth discoloration.

Who may benefit from tooth whitening?

Almost anyone. However there are some cases where the treatment may not be effective. A dentist may determine viable candidates for the process through a thorough oral examination and diagnosis. One should note that existing fillings and/or porcelain crowns will not lighten at all.

Is the process safe?

YES! Research and clinical studies indicate that whitening teeth with carbamide peroxide under the supervision of a dentist is safe for teeth and gums. Some people will get grater sensitivity to cold during the process, but it is temporary.

How does it work?

The whitening gel is placed in a thin bleaching tray that fits over your teeth. As the active ingredient in the gel, carbamide peroxide, is broken down, oxygen enters the enamel and dentin and bleaches the colored substances. The structure of the tooth is not changed; only the tooth color is made lighter.

How long does it take?

Results are usually seen after the first application. Maximum results generally occur when the process is continued for 10-14 nights. Stubborn stains may take longer. There are new stronger gels that can be used as you sleep, with quicker results.

Are there any side effects?

Some people experience temporary increased tooth sensitivity to cold during the treatment. These symptoms disappear within 1-3 days after interruption or completion of the treatment.

How long do the results last?

The teeth will always be lighter than they once were. However, some patients may need a tooth whitening "touch-up" for 1-2 days, once or twice a year.
