Types of Teeth Whitening

There are many types of teeth whitening techniques used by both dentists in offices and individuals at home. These techniques are provided by a variety of companies, each providing different levels of whitening power. Like most procedures, teeth whitening comes with a small amount of danger to the health of a patient's mouth.

  1. High-Concentration Gel

    • High-concentration gel is used in both dental offices and home kits to whiten teeth. The gel is made from carbamide peroxide, which is applied as an oxidizing agent via plastic trays. Within three sessions of 15 to 20 minutes each, results are apparent.

    Low-Concentration Gel

    • At-home kits generally use a method of gel application that is less concentrated. This uses the same application process as the higher-concentration gel, however, since the amount of carbamide peroxide is less, whitening takes 5 to 14 days.

    Laser Bleaching

    • Laser bleaching uses light energy to accelerate the peroxide molecules in order to whiten teeth. This is performed at a dental office and uses either an argon or ultraviolet rays. The process generally takes one hour and requires a single visit.

    Internal Bleaching

    • Patients who undergo endodontic therapy and suffer from staining caused by internal staining can receive internal bleaching. This process requires a hole to be drilled into the tooth and the pulp chamber is filled with peroxide gel.

    Warning

    • Each teeth whitening procedure has dangers associated with use. Carbamide peroxide is converted into hydrogen peroxide, capable of causing chemical burns on the gums. Laser bleaching can cause an inflammatory response in the gums, while internal bleaching can damage the interior of the tooth.
