As the saying goes, “Toothache is not a painful disease, but a painful one”, which is indeed a good reflection of the specific performance of toothache. It is one of the common symptoms of oral diseases, which can be seen in western medicine such as tooth decay, pulpitis, periapical inflammation and dentin allergy. It is a common symptom in oral diseases, which can be seen in western medicine such as dental caries, pulpitis, periapical inflammation and dentin allergy. Tooth decay: A kind of progressive disease of hard tissue of teeth caused by the action of multiple factors in the oral cavity, which is manifested as inorganic demineralization and organic decomposition, and the evolution process from color change to the formation of substantial disease with the development of the disease. Dental caries is a bacterial disease, so it can cause pulpitis and periapical inflammation, and even inflammation of alveolar bone and jaw bone. The secondary infection of dental caries can form foci and cause or add arthritis, periostitis, chronic kidney disease and many kinds of eye disease and other systemic diseases. Tooth decay should be given priority to health care and prevention. If the cavity becomes big and deep, the toothache may appear when eating, and the pain may increase when eating sweet food or too cold or too hot food. At this time, we can use anti-acid toothpaste and warm water to brush the teeth, if necessary, use folk remedies to relieve the pain, but the effective treatment method should be to fill the cavity. Pulpitis: It is mostly caused by infection of pulp due to deep caries or stimulation of chemical or temperature, and its pain is spontaneous, paroxysmal pain, cold and hot stimulation pain and percussion pain. For the emergency treatment of this kind of toothache, fenbid 300mg can be taken orally twice a day to relieve the pain, or use folk remedies to relieve the pain. The root treatment is done by grinding open the pulp chamber with an anvil under local anesthesia. Periapical periodontitis: Mostly caused by the spread of pulpitis to the root canal opening, resulting in inflammation of the periapical tissue. It presents as a persistent toothache. The affected tooth has an elongation sensation, palpable and pressure pain, and cannot bite food. At this time, you can take anti-inflammatory and pain-relieving drugs, such as vincristine IV 0.5 grams, 3 times a day; methotrexate 0.4 grams, 3 times a day, anti-inflammatory pain 25 mg, 3 times a day; and eat soft food. Folk remedies are also available for emergency pain relief. After the inflammation has subsided, root canal treatment will be performed. Traumatic tooth injury: such as accidental fall, bruise or bite into the grit when eating, resulting in tooth fracture or tooth cracking, causing toothache. You can take anti-inflammatory and painkilling drugs first, or use folk remedies to relieve pain. If you have the condition, you should go to the dentist to deal with it. Wisdom tooth pericoronitis: wisdom tooth pericoronitis: wisdom tooth eruption difficulties (obstruction), coupled with poor oral hygiene, causing inflammation, swelling and pain around the crown tissue. It is possible to rinse the mouth with mouthwash such as Koutai or Koushu, take anti-inflammatory and pain-relieving drugs or use folk remedies to relieve pain. Remove the blocked tooth after the inflammation has subsided. In addition, influenza, trigeminal neuralgia, jaw bone cyst or tumor, hypertension, heart disease can sometimes cause toothache. Therefore, for those who complain of toothache, but do not have any lesions in the teeth, they should not blindly abuse painkillers and should go to the hospital for specialist treatment in time. Periodontitis: Periodontitis is a chronic inflammation of the gum and periodontal tissues, a destructive disease characterized by the formation of periodontal pockets and inflammation of the pockets’ walls, resorption of the alveolar bone and gradual loosening of the teeth, which is the main cause of tooth loss in adults. The disease is caused by plaque, tartar, food impaction, poor restorations, bite wounds, etc. The gums become inflamed and swollen, while the plaque buildup increases and expands from supragingival to subgingival. Due to the characteristics of the subgingival microecological environment, the subgingival plaque contains a large number of virulent periodontal pathogenic bacteria, such as Bacillus gingivalis, Bacillus intermedius and Spirochete, which aggravate and extend the inflammation of the gums, leading to periodontal pockets and alveolar bone resorption, resulting in periodontitis. The teeth loosening, gum redness and bleeding, bad breath, gum atrophy, acid, sweet, cold and hot food pain, etc. caused by periodontitis can be treated with Chinese herbal medicine tooth Xuan San, which is very effective. If the periodontitis is serious, it is necessary to scrape treatment subgingival scraping to remove plaque, tartar, choose antibacterial drugs to control inflammation, bite jaw adjustment, etc. Clinical manifestations: Toothache is a common disease. It is characterized by redness and swelling of the gums, painful hot and cold stimuli, and swelling of the cheeks. Toothache is mostly caused by gingivitis and periodontitis, dental caries (tooth decay) or fractured tooth which leads to pulp (dental nerve) infection. In Chinese medicine, toothache is considered to be caused by external wind, incandescent stomach fire, kidney deficiency and fire, and insect erosion of teeth. Gingivitis is a common periodontal tissue disease. It is caused by inattention to oral hygiene, long-term stimulation of the teeth by soft tartar and hard tartar formed by food debris and bacteria around the teeth, and incorrect brushing habits and vitamin deficiency. The gums are bright red or purple, swollen and flabby, sometimes there is erosion at the gingival margin or the inner bud tissue is proliferated and turned out, the gums bleed easily when brushing or eating, but generally there is no spontaneous bleeding, the patient has no obvious conscious symptoms, sometimes there can be itching or swelling, bad breath is obvious. Periodontitis is a common disease of the oral cavity, and its causes are complex. Such as tartar, tartar, embedded food, bad restorations and other local factors of stimulation, gum damage, coupled with the role of bacteria, so that the periodontal membrane broken ring; vitamin C absorption, utilization disorders; vitamin D deficiency and various factors caused by the body resistance to decline, can trigger periodontitis. Toothache is the main symptom of this disease. In the early stage, gum itching, discomfort, bad breath, followed by red, swollen, flabby gums, easy bleeding, pain, recurring episodes. The periodontal membrane between the gums and the roots of the teeth is destroyed over time, forming a bag called a periodontal pocket, which is often overflowing with pus, and when the inflammation continues to expand, it can become a periodontal abscess, which is aggravated by local pain and swelling, which is hard at first and then becomes soft and fluctuating, and can break through on its own and flow out pus, and after the pus comes out, the pain can be relieved, or it can recur and be very painful.
