I was reading an interesting article on ScienceDaily.com today about anthropologists having discovered new research use for dental plaque and the information that can be garnered from it regarding ancient human diets. Nutrition and diet are very important to the dental field and getting the best outcome of dental treatment. In addition to periodontal disease, dietary deficiencies have been associated with with such oral health conditions as; osteoporosis of the surrounding bone, loss of taste, bad breath, and mouth and tongue sores. Deficiencies in vitamin C, iron and zinc could compromise the resistance of our gum tissue to the bacteria in dental plaque. So what recommendations should a dentist make to their patients regarding diet and nutrition? The number one suggestion is to eat a well-balanced diet and to take necessary nutritional supplements; otherwise your teeth and gums may be at risk.
