In the teeth whitening procedure the teeth is cleaned and lightened using laser light treatment and it also removes stains and discoloration, improving the overall beauty of the smile in a cosmetic way. Teeth whitening or teeth bleaching is among the most popular and affordable cosmetic dental procedures because it can greatly improve how your teeth look. Most dentists perform this affordable, laser light treatment to make the teeth white for sparkling smile enhancement.
Some people are born with teeth that are more yellow than others. Others have teeth that yellow with age. Your natural teeth color can also be affected by many factors. Surface stains (called extrinsic stains by dentists) and discoloration can be caused by:
The cause of tooth discoloration can be:
Internal stains (called intrinsic stains by dentists) can be caused by:
Whitening (bleaching) can be done either in a dentist's office or at home, using a system dispensed by your dentist. Both methods use tooth-bleaching gels that oxidize out the stain. It's not uncommon for teeth to become slightly sensitive during the whitening process.
At-home whitening is the more popular approach today. Your dentist takes an impression of your teeth and makes a custom-fitted tray, which you fill with a whitening gel and wear up to two hours daily or at night for about two weeks. Many whitening kits prescribed by dentists today contain a solution of 10-15% carbamide peroxide. When done under the supervision of your dentist, at-home whitening is very effective.
Less frequent and more expensive, this procedure takes from 30 minutes to one hour per visit, and you may have to return for several visits to achieve the desired whiteness. To protect your mouth, a gel-like substance may be applied to your gums and a rubber "shield" may be placed around the necks of the teeth. An oxidizing agent (the bleaching solution) is then applied to your teeth. Sometimes, a special light is used at five-minute intervals to help activate the whitening agent.
You will need one to three appointments depending on your oral status. The number of visits will depend on how severe your stains and discoloration are and how white you want your teeth to be as a result of this surgery. Different types of stains and discoloration respond differently to the whitener and treatment.
If you find that your gums are white or sore, follow up with your professional dentist at his clinic. The stains will come back if you smoke or consume a lot of staining foods or drinks. In such cases you may see the whiteness start to fade in as little as one month. If you avoid these sources of staining, you and your near and dear ones will enjoy your sparkling smile for 12 to 18 months with the same cost.
There are two methods of teeth whitening - home and office. In both cases, the principle is the same - the decomposition of hydrogen peroxide under heat to release singlet oxygen, which breaks down the particles by oxidation leading to discoloration. This process is similar to the process of bleaching the hair.
