俗话说：“牙疼不是病，疼起来真要命。”牙痛是多种牙病的共同症状，它有刺激性疼痛与自发性疼痛、钝痛与锐痛之分。牙痛最常见于龋齿病，俗称蛀牙，在牙齿上往往有褐色小洞。当病变到达牙本质时，病人就会感到牙痛，尤其是在吃较便食物或遇冷、热、酸、甜时，疼痛更加剧烈。 As the saying goes: “Toothache is not a disease, it really terrible pain.” Toothache is a common symptom of a variety of dental diseases, it has irritating pain and spontaneous pain, dull pain and acute pain points. Toothache is most common in dental caries, commonly known as tooth decay, and often has brown holes in the teeth. When the lesions reach the dentin, the patient will feel a toothache, especially in eating more food or cold, heat, sour, sweet, the pain more intense.
