Internal Bleaching

Internal bleaching is a conservative cosmetic procedure used to lighten a tooth that has become darkened from within. Unlike traditional whitening, which works on the outside surfaces of the teeth, internal bleaching treats discoloration from the inside of the tooth. Common causes of discoloration include dental trauma, bleeding within the tooth, or breakdown of pulp tissue. .

This procedure is performed after root canal therapy has been completed. A protective barrier is first placed over the root canal filling, and a specialized bleaching material is carefully inserted into the pulp chamber. The tooth is then temporarily sealed, allowing the whitening agent to work from the inside out. Depending on the degree of discoloration, the bleaching material may be replaced over one or more visits until the desired shade is achieved. Once the tooth has reached the desired color, the bleaching agent is removed and the access opening is permanently restored.

Internal bleaching is often an excellent alternative to veneers or crowns because it can significantly improve the appearance of a darkened tooth while preserving healthy natural tooth structure.
