Teeth whitening is an ever increasing procedure being requested by many patients. In this paper, I will be discussing the biological and chemical mechanisms of teeth whitening, the difference between in office and take home whitening, current products on the market, and current issues and safety concerns regarding teeth whitening. Knowledge of these topics is important to have to be able to safely recommend in office or at home whitening options. Color can be viewed based on three different dimensions. The Munsell color system classifies colors based on hue, value, and chroma. Hue describes the color family or underlying tone (e.g., green, blue, red). Value describes the brightness or darkness on the scale on zero to ten, zero being white and ten being black. Chroma describes the saturation or vividness of a color. The appearance of teeth is affected in three ways by whitening. First, whitening reduces the amount of chroma in the tooth—the pigment or intensity of color is reduced. Second, whitening changes the hue, or color, or the teeth. Thirdly, whitening changed the value of the teeth. It is important to understand the natural color of teeth. Individual teeth vary in color in their thirds. The incisal third is usually the lightest because it is composed of mostly translucent enamel. The middle third is the next darkest and is closer to the color of dentin, but is modified by the translucent enamel that covers it. The cervical third in the darkest portion of the tooth because enamel in thinnest in this region, and the color of dentin is more visible. When looking at the smile as a whole, the shade of individual teeth varies between each other. The maxillary centrals are usually the lightest teeth and have a higher value.

It is recommended that clinicians delay the placement of bonded restorations until 1-3 weeks after treatment (Can-Karabulut et al 2011). Since whitening agents produce free radicals, some people may question the carcinogenicity of those products. A literature review conducted by Munro et al in 2006 looked at more than 100 clinical studies. Results showed that there is no date to show that hydrogen peroxide poses a carcinogenic risk to human oral mucosa at the exposure levels associated with tooth whitening. Mice models did show that hydrogen peroxide at high levels is genotoxic and carcinogenic, but humans posses more catalase activity than animals. Also, hydrogen peroxide concentrations were found to be highest in the gingiva, but this is a site where oral cancer is rarely found.
It is regarded as a great challenge to be achieved in adhesive dentistry. The root dentin differ from the coronal dentin, thus the bonding will be different. The achievement of good infiltration and micromechanical retention remain a challenge because of limited access and vision, regional variation in bond strength, presence of a thick smear layer. The bond strength differs along the root canal and it is lower than coronal dentin.
In White Teeth, Zadie Smith warns against the dangers of purism and letting cultural background completely shape one’s identity while simultaneously paying tribute to the rich heritage and beliefs of her characters. It is a cautionary tale for immigrants but is never dismissive of their past. Smith is merely advising against tunnel vision and stressing the need to adapt to one’s environment. She shows the beauty that can stem from adaptation while warning that an inability to do so will lead to one’s downfall. London plays an especially important role as the battleground where the past and the present clash; a melting pot with a large immigrant population and inevitable moral struggle.

Healthcare is a necessity to sustain society. Dentistry is an area of healthcare that I feel extremely passionate about because access to proper dental care is limited, especially in the underserved communities. As an African American, I want to become a dentist and healthcare provider in the hopes of helping patients and adding to the diversification of the field. With a growing minority population in the United States, it has become apparent that there is a shortage of black dentists. This is problematic because underrepresented minorities are in great need of access to culturally connected dentists who understand their clinical needs as much as their lives and their challenges. I believe that when the profession includes a range of ethnicities
