Maintaining good oral hygiene and health is a given. Every person knows how essential it is to brush and floss daily and to make periodic visits to a capable Philadelphia dentist for a comprehensive dental check-up, especially if the patient is suffering from dental problems like cavities and gum disease. Furthermore, it is also important to be aware of the right kind of food and drinks to consume. There are plenty of foods that should be avoided because of the damage they cause to teeth: sodas, fruit juices, coffee, tea, and hard candies are some of the more notorious examples of sugary consumables that result in the formation of cavities or the staining of teeth. At the same time, however, there are also plenty of food and drinks that contribute to good oral health and hygiene.
A recent study published in the Academy of General Dentistry's (AGD) clinical journal General Dentistry, for instance, evaluates the relationship between dairy products and the development of cavities and tooth decay. An article on Science Daily reports:
The study sampled 68 subjects ranging in age from 12 to 15, and the authors looked at the dental plaque pH in the subjects' mouths before and after they consumed cheese, milk, or sugar-free yogurt. A pH level lower than 5.5 puts a person at risk for tooth erosion, which is a process that wears away the enamel (or protective outside layer) of teeth. "The higher the pH level is above 5.5, the lower the chance of developing cavities," explains Vipul Yadav, MDS, lead author of the study.
Results of the study show that the consumption of cheese increased pH levels, while the milk and sugar-free yogurt showed no changes. According to the article on Science Daily, perhaps this was due to the “increased saliva production (the mouth's natural way to maintain a baseline acidity level), which could be caused by the action of chewing. Additionally, various compounds found in cheese may adhere to tooth enamel and help further protect teeth from acid.”
Dentists do not prohibit the consumption of foods that may damage the teeth; they do, however, encourage brushing and flossing after eating, as well as consuming more teeth-friendly foods. A reliable dentist in Philadelphia such as Gerald Regni, DMD, can examine your teeth and advise you on what needs to be done to maintain good oral health.
