Answer: Teeth are like bones. They need to be taken care of because if not they can decay. Tooth decay formation takes place due to a process called demineralization. The acids that cause tooth demineralization (cavity formation) are produced by specific types of bacteria that live in dental plaque (primarily lactobacilli and mutans streptococci).
Answer: periodontitis 1. Inflammation of the periodontium.2. A chronic inflammatory disease of the periodontium occurring in response to bacterial plaque on the adjacent teeth; characterized by gingivitis, destruction of the alveolar bone and periodontal ligament, apical migration of the epithelial attachment resulting in the formation of periodontal pockets, and ultimately loosening and exfoliation of the teeth.
Answer: Stay away from foods containing sugar. Sugar is the cause of tooth decay. Try to eat sweets that are sweetened with sugar alcohol which does not cause tooth decay. If sugar can not be avoided then brush after eating sugary foods. Also floridated water helps combat tooth decay.
Answer: In the Dental community we call it "dental caries" or a "carious lesion." Caries refers the disease in which hard tooth structure becomes damaged or decayed as result of bacterial processes, primarily due to Streptococcus mutans. Fermentable carbohydrates such as sucrose fuel these bacteria which produce acids. If not removed from the tooth surface the acids will begin to demineralize the hydroxyapatite crystal structure of the enamel and dentin. I suppose you could also call it a "cavity."
Answer: Not necessarily. Tooth decay is caused by the bacteria n your mouth feeding on sugar in your food or drinks. The by-product is acid which eats away at the enamel - causing cavities. Eating a balanced diet, and brushing regularly after meals will help to reduce the amount of harmful bacteria.
