This makes it easy to draw a comparison between people that care for their teeth and those who don’t. However, access to dental knowledge and services which the lower class often times doesn’t have is very different between the poor and the rich.

The Connection Between High Blood Sugar Levels and Periodontal Disease. Saliva contains glucose; therefore, if you have uncontrolled diabetes, the amount of glucose present in your saliva is elevated. We naturally have somewhere between 200 to 300 bacterial species in our mouths: Some of these bacteria are good and some of them are bad. Streptococcus mutans is typically the bacterium responsible for causing tooth decay; whereas, periodontal disease is usually caused by a mixture of Porphyromonas gingivalis and Treponema denticola. Elevated glucose levels assist the harmful bacterias, Porphyromonas gingivalis and Treponema denticola, by providing the substance necessary to produce the acid that combines with our saliva to form the soft, sticky film referred to as plaque.

While Scholars Head and Dyer focus more on the racial relations between the community of people of color and overalls society, scholar Nick Bentley has chosen to focus on the issues in this novel from a most vast point of view. The critical themes are not just within the microcosm of people of color. He theorizes that England in its entirety is counterproductive to the agenda. Specifically to the novel White Teeth, he criticizes author Zadie Smith for antagonizing the delicacy of the interactions with different cultural groups. Although he does provide compelling arguments that support his claim, it would be advantageous to view the provocation as a critique for improvement.
