There are a number of reasons teeth lose their luster. Smoking is perhaps one of the most common, followed by food and beverages that stain our teeth, like wine and coffee. Aside from these external factors, however, a tooth can undergo staining from within the tooth itself. Typically this is due to a structural defect within the tooth, a dying tooth, or because blood and other bodily fluids penetrated the tooth during prior root canal treatment. Restoration of a discolored anterior tooth with a porcelain crown on a post is an invasive procedure involving reduction of tooth structure and is not cost effective. Regardless of the cause, there are still opportunities to restore such a tooth to match the color of its adjacent teeth without sacrificing the tooth structure, by bleaching the tooth from the inside-out – a process known as “internal” tooth bleaching.
What is internal tooth bleaching?
Internal bleaching is a method of whitening a tooth from the inside out. Unlike external bleaching, which brightens teeth from the outside in, internal bleaching brightens teeth from the inside out.
How does it work?
The process for internal bleaching involves a root canal to remove any pulp that is infected and the insertion of a chemical oxidizing agent into the tooth. The agent is left in the tooth for up to two weeks and then replaced with more chemicals until the tooth achieves the level of whiteness desired. Once the series of treatments is complete, the hole is filled, ensuring that foreign matter will not be able to invade the tooth and cause other problems.
