Teeth whitening can be done through the application of bleaching agents directly to the teeth. You can choose to perform teeth whitening at home with over-the-counter kits or make an appointment with a dentist for professional bleaching. Professional whitening uses a higher concentration of the bleaching agent and may use laser therapy to speed up the process. Before you use any type of whitening product, you should discuss the long-term side effects with your dentist.
Types
There are several potential long-term effects caused by teeth whitening. The bleaching agent used to whiten the teeth may deteriorate the enamel of the teeth. If the whitening solution comes into contact with the gums, it may lead to gum irritation. Hot and cold sensitivity while eating and drinking usually goes away a couple of days after the whitening procedure, but increased sensitivity can occur for prolonged periods.
Expert Insight
In 2004, Georgetown University Hospital researchers at the 6th International Conference on Head and Neck Cancer presented a possible correlation between teeth whitening and oral cancer. Their findings were published in the Oct. 10, 2004, issue of "Oncology Times." They documented two patients who developed oral cancer prematurely and were frequent users of teeth whitening products. During animal studies, lab rats developed tumors in the mouth after hydrogen peroxide, a common teeth bleaching agent, was ingested. At this time, there are no other studies done that show a link between cancer and teeth whiteners.
Features
According to the Family Gentle Dental Care website, when you have whitening done at a dentist's office, a customized tray is placed on your teeth. At home kits typically include non-form fitting trays. Customized trays reduce the risk of hydrogen peroxide leaking and ingestion.
Considerations
There is an increased risk of long-term problems occurring if the bleaching agent is not applied properly. If an at-home whitening kit is used, all manufacturer's instructions should be followed. The bleaching agent is more likely to damage the teeth and gums if left on for prolonged periods or if whitening is done too frequently.
Warning
Certain individuals should not whiten their teeth due to the increased risk of long-term complications. According to the Online Surgery website, people with thin enamel should not undergo teeth bleaching procedures since this can worsen their condition. If you are allergic to peroxide, you should avoid the use of whitening systems.
