Patients often come to the dentist and ask for a prescription for anti-inflammatory medication or buy it themselves at the pharmacy, but does it work? First of all, the most common dental pain in the clinic are: pulpitis, apical infection, periodontitis. Pulpitis and apical inflammation The pulp is exposed due to hard tissue loss or deep caries, and root canal treatment is necessary to cure pulpitis and apical inflammation due to pulp exposure. Oral anti-inflammatory drugs can not play a therapeutic role (the severe pain cannot be relieved because the tooth body is the only hard tissue connected to the outside world as a very thin root canal, the pulp is filled with blood during the inflammation period, the pressure of the rather closed container increases, the pain is naturally severe, only the pulp cavity is opened and decompressed through treatment can be cured.) Sometimes the treatment of apical infection can be combined with anti-inflammatory drugs. Periodontitis can be relieved by oral anti-inflammatory drugs in the acute stage, but the irritants need to be removed to cure the disease, otherwise the disease will always recur, for example, calculus and soft tartar around the gums or roots, which must be removed by instruments, supplemented by anti-inflammatory drugs. In short, oral diseases need to be examined and treated, and do not abuse antibiotics to prevent drug resistance, dysbiosis, delayed disease, and pain.
