Whitening of the teeth is a service provided for patients who desire a brighter smile. Tooth whitening can be performed to reduce discoloration and staining, or simply to provide the patient with a whiter, brighter smile.
Overview of Tooth Whitening
Tooth whitening is often used if the patient wants to correct discoloration of the teeth by removing brown or yellow staining. The term "tooth whitening" can refer to a number of techniques to improve the brightness of the patient's teeth. Among them are chemical whitening, abrasive teeth brightening, mild acid whitening, and laser teeth whitening, which is the newest technique.
Teeth Bleaching
Teeth bleaching is a chemical process that is 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 done by the patient at home, in which case the dentist will provide the materials. The home method is often used because it saves the patient the inconvenience of having to make an office visit for each treatment.
Before the patient starts 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 and also helps increase the margin of patient safety.
The steps in the home tooth whitening regimen are fairly straightforward. The cosmetic dentist's office provides the patient with materials and instructions and can also answer any 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 lasts for one hour, during which time you will have the tray and solution in your mouth. Depending upon your needs the and results you desire, 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 tooth whitening last?
Tooth whitening must be maintained. Results can last for one 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:
It usually only takes one visit to achieve a bright smile.
Disadvantage:
The sudden change of color is likely to be noticed by those around you right away. This is the more expensive of the procedures available, but also the quickest.
