How Does A Tooth Whitening Procedure Work?

Teeth whitening or teeth bleaching, as it’s also known is the process of removing brown or yellow stains from teeth through chemical processes. Teeth whitening can be done in a number of different ways, depending on the level of stain you’re dealing with. Interested readers can find more information about them at Innaloo teeth whitening

There are basically two methods, although it’s not always obvious which one to use. They are:

Bleaching with peroxide: A simple mixture of hydrogen peroxide and carbamide peroxide is used to stain teeth. The peroxide can bleach both the back and front teeth depending on how severe the stain is. Most cosmetic dentists advise that toothpaste with a small amount of carbamide peroxide is sufficient. People with discolored teeth usually respond well to this method.

Teeth bleaching with gels and trays: A thin film of a bleaching agent is placed onto the teeth, over the top of a plastic tray. The tray is then worn for a certain period of time. When the bleaching gel is no longer visible after wearing the tray, a second application of the gel is performed. It is essential to wear the trays for a minimum of 2 hours to ensure complete results. Most cosmetic dentists advise people with sensitive teeth to avoid this method of teeth whitening, as there may be irritation.
