Tooth whitening products for use at home work over a short period of time but users should be aware of common side effects and note that long-term data on their use are not yet available. Products for whitening teeth at home are available 'over-the-counter' or from dentists. This review looks at whether such tooth whitening products work and, if so, which are more effective. The review focuses on products which have a chemical, bleaching action rather than an abrasive action. Results found that over a short period of time these products do work, and that there are differences between the products, mainly due to the levels of active ingredients, hydrogen peroxide and carbamide peroxide. People should be aware of common side effects such as tooth sensitivity and irritation to the gums and note that long-term data on the use of such products are not yet available.

    • "Tooth bleaching has become one of the most popular cosmetic procedures offered in dental practice.1 Several products and techniques are available for vital tooth bleaching, and vary in concentration and type of end products released.2,3 The whitening procedures can be performed in the office by the dentist or at home by the patient without dentist supervision.

    ABSTRACT: This review investigates erosion and abrasion in dental structures undergoing at- home bleaching. Dental erosion is a multifactorial condition that may be idiopathic or caused by a known acid source. Some bleaching agents have a pH lower than the critical level, which can cause changes in the enamel mineral content. Investigations have shown that at-home tooth bleaching with low concentrations of hydrogen or carbamide peroxide have no significant damaging effects on enamel and dentin surface properties. Most studies where erosion was observed were in vitro. Even though the treatment may cause side effects like sensitivity and gingival irritation, these usually disappear at the end of treatment. Considering the literature reviewed, we conclude that tooth bleaching agents based on hydrogen or carbamide peroxide have no clinically significant influence on enamel/dentin mineral loss caused by erosion or abrasion. Furthermore, the treatment is tolerable and safe, and any adverse effects can be easily reversed and controlled.

    ABSTRACT: Although whitening is the most commonly requested dental procedure, it is important to consider the potential success for a patient before beginning a treatment plan. The care provider must assess the condition of a patient's teeth, baseline color, diet, aging, and tooth health, and consider these factors when determining the possible whitening benefits for the individual. Some patients are better whitening candidates than others, so the patient must know all of their options and limitations for whitening success including sensitivity and post-whitening procedures before the treatment begins.
