加湿器批发价格|冬季晒太阳少缺维生素d易得牙病
 

　　龋齿引起的牙痛是因为牙体有龋洞，遇到冷、热、酸、甜等刺激或食物嵌塞龋洞时而感觉牙痛。
天气冷了，口腔中心的病人也来了很多，每天都忙得不行,光波炉的危害应注意几点，一天看牙的病人都超过40人，比平时多了三成多。为什么每年冬季，尤其是在气温骤降的天气里，到牙科就诊 的患者就会明显增多?
一般来说，引起牙痛的主要原因是口腔疾病，如龋齿、急性牙髓炎、牙周炎、牙齿隐裂或根折等。龋齿引起的牙痛 是因为牙体有龋洞，遇到冷、热、酸、甜等刺激或食物嵌塞龋洞时而感觉牙痛。去除刺激因素后，牙痛可立即停止 。急性牙髓炎引起的牙痛，表现为自发性、阵发性疼痛，遇到冷热刺激或夜间休息时疼痛加剧。其他病因引起的牙 痛,加湿器批发价格，虽然机理不同，但有一点是共同的，即遇到冷、热刺激时疼痛加剧,水宜生水杯。
　　冬季天气寒冷，人们呼吸空气时，牙齿也会间接地接触到冷空气。尤其是感冒鼻塞时，牙齿与冷空气接触就更 多了，自然容易引起牙痛。当然，热刺激也容易引起牙痛，例如趁热吃饭，尤其是冷热交替，牙痛的发生率就会大 大提高。
冬季的其他要素，如湿度、风和日照，也对牙痛有直接或间接的影响。冬季是蔬菜淡季，空气又比较干燥，人们容 易“上火”，引发牙痛。现代气象保健学研究证实，当冷锋过境或在冷气团的控制下，容易发生牙周炎和牙龈出血 。在刮风(尤其是偏北风)的天气下，牙周炎容易发作。龋齿在冬季和早春发病率高，夏季发病低。这主要是因为 冬季和早春的日照少，紫外线辐射比较弱，体内维生素D的含量较少，因此容易发生龋齿,加湿器厂家。
呵呵，所以建议冬季护齿不仅要保持口腔卫生，还应注意天气变化，多吃蔬菜水果，适当补充维生素D，避免让牙 齿遭受冷、热刺激等。
