The large temperature difference between morning and evening in spring will affect the human body's self-regulation ability. The symptoms of toothache in some people are also related to the change of temperature. Xing Puchun, a stomatologist at Nankai Hospital of traditional Chinese Medicine Affiliated to Tianjin University of traditional Chinese medicine, suggested that if the human body's self-regulation ability is weak, the resistance of periodontal tissue will also become weak, so it is easy to cause oral diseases such as pulpitis and periodontal disease. Because the plaque and calculus deposited on the teeth erode the teeth and are usually neglected, when the resistance of periodontal tissue decreases, it will turn into an acute disease and the teeth will suddenly ache. Don't forget to brush your teeth after dinner, no matter how busy you are. Only by protecting oral hygiene can we stay away from serious oral diseases from the root. In daily life, it is recommended to drink more water and eat more light diet. Usually, pay attention not to eat snacks or sweets before going to bed, eat less spicy and stimulating food, and eat more fruits and vegetables to supplement vitamins. In addition, if it is an oral disease with mild symptoms, you can prevent the further development of symptoms by carefully brushing and cleaning your teeth; If the symptoms are serious, not only clean the teeth, but also carry out targeted treatment. It is recommended to go to a professional oral medical institution for examination in time. (outlook new era)
