Most toothaches are caused by caries, which is what we usually call cavities. During the treatment, a dental drill needs to be used to remove the decayed substances on the surface of the cavities, and to remove the infected dental nerve blood vessels in the teeth. The inner root canal is filled, and the damaged crown is filled with veneer or resin material to restore the original shape and function of the tooth. Toothache, can it really be pulled out? Toothache is a disease, and dentists need to intervene to stop the pain for toothache patients. After the patient arrives at the hospital, the doctor must first make a detailed examination of the patient to find out what is causing the toothache. Usually, nerve-induced pain is not easy to distinguish from toothache. Only after a professional examination can we determine who the “culprit” is. If the toothache is caused by the tooth itself, such as pulpitis and root tip inflammation caused by caries; or toothache caused by periodontitis and pericoronitis of wisdom teeth, doctors can use special interventions to quickly Pain is stopped for the patient, and the tooth is saved and function is restored through treatment. Do you need to figure out where your pain starts? Sharp spontaneous pain: usually caused by acute pulpitis, periapical periodontitis, periodontal abscess, papillitis, and pericoronitis; spontaneous dull pain: usually caused by chronic gingivitis; provocative pain: usually caused by Caused by dentin hypersensitivity; occlusal pain: Usually caused by acute or chronic periapical periodontitis. Regarding the prevention and care of toothache, we need to do the following: eat less sweets to prevent tooth decay; prevent gum recession and ensure subgingival cleaning; reduce or eliminate plaque, change the oral environment, and create clean conditions to prevent caries The most important part is to develop a good habit of brushing your teeth correctly and gargling after meals; eat more coarse, relatively firm and fibrous foods. However, it should be noted that we should fully chew food with relatively hard texture. The purpose of this is to regulate and promote the growth and repair of periodontal tissue; it is beneficial to reduce the occurrence of pit and fissure caries; reduce or control the sugar in the diet intake. Children, in particular, should develop good living habits from an early age, do not eat sugar before going to bed, and eat more vegetables, fruits and foods containing calcium, phosphorus and vitamins in three meals a day.
