Oral health is affected by dieting actions. Teeth can be harmed by crash diets, eliminating meat or fatty foods, diet pills or appetite suppressants and behaviors like fasting, binging and purging. Weight control actions may affect more than just body size, they can also place teeth in danger as diet pills can decrease salivation rate or salivary flow and cause dryness in the oral cavity, devastating oral health and cause infected and swollen gums eventually. Fasting can cause decrease of minerals that are needed by the body to help maintain healthy body and oral health, which includes calcium, anorexia that can lead to vitamin and mineral deficiency. Diet plan and dieting behavior should be notified to your dentist because diet is an essential part of an individual's medical history.
