Internal Bleaching: Dealing with Tooth Discoloration

You may be wondering why that one tooth is significantly darker than the adjacent teeth. And after you've tried all the whitening tips and strips you can get, and it still looks gray.

Several causes of discoloration are: extrinsic stains, these can be from smoking habits, or from food and beverages that causes staining; and intrinsic stains which causes discoloration inside out. The causes can be from a dying tooth that was caused by caries or physical trauma, or from a previously root canal treated tooth.

Internal Bleaching

In contrast to a laser teeth whitening treatment which eliminates deep extrinsic stains, internal bleaching is the opposite in which it treats stains from the inside of the tooth, where the source of the problem is. This procedure brings back the tooth luster by chemically bleaching from the inside.

The infected or devitalized tooth will need to undergo root canal treatment first to treat and seal off the tooth before the internal bleaching procedure can begin.

The bleaching agent will then be placed inside your tooth, covered by a temporary filling material. This will be changed frequently, evaluated and re-evaluated until the desired natural tooth color is achieved.

Main Advantages of Internal Bleaching
