"Every autumn and winter, the number of patients who go to the hospital to see a dentist will increase significantly. Many people report that their teeth are easily injured when the weather gets cold. What's going on here?

After the autumn and winter holidays, the sunshine time is gradually shortened and the ultraviolet intensity is weakened. In addition, people wear more clothes, but also tight clothes, and lack of ultraviolet rays, which greatly reduces the synthesis of vitamin D in the body, easily damages teeth, and leads to a higher incidence of dental caries, leading to toothache. Another reason is that the weather is dry in autumn and winter, and it is easy to get angry, and people like to eat spicy food and hot meat in this weather, and the internal fire is seriously silted up, leading to toothache. In addition, in autumn and winter, people like to eat spicy hot pot and shabu shabu shabu. When they sweat, they often drink some cold beer and cold drinks, and some people even eat cold drinks such as ice cream. In this way, if the teeth have lesions such as dental caries, swollen gums, oral ulcers, periodontitis, dentin hypersensitivity, etc., then on such occasions, once they are stimulated by heat, spicy and cold in turn, it is easy to cause the attack of pulpitis and unbearable pain.
