Since tooth whitening has now become the number one aesthetic focus of many patients, there are many products and methods that can achieve a brighter smile.
Professional tooth whitening (or bleaching) is a simple non-invasive dental treatment that changes the color of natural enamel and is an ideal way to enhance the beauty of the smile. There are also over-the-counter products, but they are far less effective than professional treatments and may not be approved by the American Dental Association (ADA).
As you age, the outer layer of the enamel will wear out, eventually revealing a dark or yellow hue. The color of our teeth also comes from the inside of the teeth and it gets darker over time. Smoking, drinking coffee, tea and wine can also cause discoloration of teeth, leaving our teeth yellow and white. Sometimes the teeth change color because the child takes certain medicines, such as tetracycline. Excessive fluoride (fluorosis) during tooth development can also cause discoloration of teeth.
It is important that the dentist evaluate your teeth to determine if you are suitable for bleaching. Occasionally, tetracycline and fluorosis are difficult to bleach, and your dentist may provide alternatives such as a veneer or a crown to cover these stains. Since tooth whitening is only applicable to natural enamel, it is also important to evaluate the replacement of any old fillers, crowns, etc. before bleaching begins. Once bleaching is complete, the dentist can match the color of the new prosthesis with the new whitened teeth.
Since tooth whitening is not permanent, it may need to be patched every few years to keep your smile looking bright.
The most widely used professional teeth whitening system:
Home teeth whitening systems: Household products are usually in the form of gels and placed in custom masks (pallets) made from dental molds. The tray is worn about twice a day for 30 minutes or overnight while sleeping. Depending on the degree of staining and the degree of whitening required, it usually takes several weeks to reach the desired result.
Teeth Whitening in the Office: This treatment is done at the dental clinic and you will see the result immediately. This may require multiple visits, with each visit lasting 30 to 60 minutes. Apply bleach to your teeth while your gums are protected. When the teeth turn white, special light can be used to enhance the effect of the drug.
Some patients may experience tooth sensitivity after turning white. This feeling is temporary and will fade shortly after the bleaching process is complete, usually within a few days to a week.
