Abstract
This paper discusses studies that have researched the most effective forms of teeth whitening and the mechanism behind it. Studies discuss the oxidation of double bonds which in turn lighten the chromogens impacting the overall coloration of dentition. The three main forms of treatment that were considered in these studies include in-office treatment, at home treatment and OTC products. At home overnight bleaching proved to have the best results for both immediate and post 10 week results. At-home treatment under dentist’s care involves lower concentration of hydrogen peroxide or carbamide peroxide ranging from three to ten percent thus it takes longer time than in-office treatment (Leh, B. 2018). Factors such as food intake, beverages, smoking, and oral hygiene care can all impact the efficiency of bleaching methods. While some toothpaste brands, like charcoal toothpaste, claim to whiten teeth, research suggests that these abrasive toothpastes may lead to enamel wear. Furthermore, studies have compared the effects of chemical and herbal toothpaste and found that both can produce similar whitening effects. However, chemical products tend to be more harmful compared to herbal alternatives As dental esthetics have become increasingly important to western populations, more whitening products are readily available for consumer use. Studies warn about the adverse risks and effects of dental bleaching to be aware of for both the consumer and those applying or prescribing bleaching methods, therefore it is important for hygienists and others in the dental field to become educated and aware of the increasing bleaching product selection.
