Why does it get cold and toothache easily?

Since autumn, the weather has been getting colder day by day. Xiao Liu in the office suddenly has a bad toothache these days. He is too cold and hot to eat. It is said that he can't sleep well at night. "When he falls asleep, he wakes up with pain. 。” Xiao Liu said, "I was sleeping well, and suddenly my teeth hurt. I couldn't do anything. I had to endure it slowly, waiting for the pain to ease bit by bit, and I couldn't sleep well. It was really uncomfortable. 。” Every autumn and winter, the number of patients who go to the hospital to see the dentist will increase obviously. Many people report that when the weather gets cold, their teeth will hurt easily. How is this?

After the autumn and winter festivals, the sunshine time is gradually shortened, and the intensity of ultraviolet rays is weakened. In addition, people wear more clothes and wear more tightly, and the ultraviolet rays are insufficient, resulting in a great reduction in the synthesis of vitamin D in the body, easy damage to teeth, and a higher incidence of dental caries, leading to toothache. Another reason is that the weather is relatively 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, causing toothache. In addition, in autumn and winter, people like to eat spicy hot pot and shabu-shabu. When they are sweating, 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 already have dental caries, gum swelling and pain, oral ulcer, periodontitis, dentin hypersensitivity and other lesions, then on such occasions, once exposed to heat, spicy, cold and other stimuli in turn, it is easy to cause the onset of pulpitis and unbearable pain.
