Whitening of the teeth is performed for patients who desire a brighter smile. Tooth whitening can be performed to reduce discoloration and staining, or simply to provide the patient with whiter, brighter teeth.
Overview of Teeth Whitening
Teeth whitening is used to correct discoloration of the teeth by removing the brown and yellow staining. The term "teeth whitening" can refer to a number of techniques to improve the brightness of the patient's teeth. Among them are chemical whitening, mild acid whitening, abrasive teeth brightening and the newest technique, laser teeth whitening.
Teeth bleaching is chemical process used to lighten the color of the patient's teeth. The procedure can be performed entirely in the cosmetic dentist's office or it can be performed by the patient in their home, using a materials provided by the dentist. The home method is often used because it saves the patient from having to make an office visit for each treatment.
Before the patient embarks on the home teeth whitening regimen, the cosmetic dentist creates a custom mouth tray for the patient. The custom tray is a critical component of the treatment. It ensures that the correct amount of whitening solution is used and that the patient's teeth are properly exposed to the whitening solution. The custom made mouth tray provides for a better fit than a one-size-fits-all mouth tray to help increase the margin of patient safety.
The steps in the home teeth whitening regimen are fairly straightforward. The cosmetic dentist's office provides the patient with the materials and instructions and also answers questions the patient may have about the routine. Your dentist's office can also provide you with off-site supervision should you have any questions once you've begun.
A home whitening session can last for two to three hours, during which time you will have the tray and solution in your mouth. Depending upon your needs and desired results, your dentist may instruct you to keep the tray in your mouth overnight. Typically, you will follow your home teeth whitening regimen for two to three weeks, after which time you will return to your cosmetic dentist for a follow up visit.
How long does teeth whitening last?
Teeth whitening is not a permanent procedure. Results can last for one to or more years, depending upon your personal habits. In most cases, the whitening procedure is very effective and the patient is pleased with the results.
LASER BLEACHING (In-Office)
Using a laser with a whitening gel, this is an in-office bleaching system. The translucent bleaching gel is applied to the teeth and a laser light is used to activate the crystals to absorb the energy from the light and penetrate the teeth enamel to increase the lightening effect on the teeth. The length of time in the cosmetic dentist's chair depends on the degree of discoloration you have.
Advantage: One visit is usually all it takes for a bright smile.
Disadvantage: The sudden change of color is likely to be noticed by those around you immediately. This is the more expensive of the procedures available, but also the quickest.
