There are many causes. The most common include aging, consumption of staining substance (coffee, tea, cola, tobacco), trauma, nerve degeneration, and old restorations. During tooth formation, consumption of tetracycline or excessive fluoride may also cause tooth discoloration.
The bleaching gel is placed in a thin bleaching tray that fits over your teeth. As hydrogen peroxide, the active ingredient in the gel is broken down; oxygen enters the enamel and dentin and bleaches the colored substances. Only the tooth color is made lighter, while the structure of the tooth is unchanged.
Yes! Research and clinical studies indicate that whitening teeth with hydrogen peroxide under the supervision of a dentist or a hygienist is safe for teeth and gums. In fact, many professionals consider this whitening process the safest cosmetic dental procedure available today.
Results are often seen after the first application. Ideal results generally occur when the process is continued for 10-14 days. Faster results may be obtained with more frequent application and/or longer wear periods.
Some people experience temporary tooth sensitivity during the treatment. These symptoms always disappear within 1-3 days after interruption or completion of the treatment.
The teeth will always be lighter than they were. However, some patients may want to "touch-up" their teeth by re-whitening for one or two days, usually once or twice a year. This is especially useful if they continue to use staining substances such as caffeine or tobacco products.
