Patients with pulpitis can take cephalosporin, which is also symptomatic and can relieve the symptoms of pulpitis to a certain extent, thus making it appear temporarily painless. The vast majority of cases of pulpitis are caused by bacterial infection to the pulp, whether it is caries infecting the pulp step by step through cavities in hard tissues or periodontal lesions infecting the pulp. As a broad-spectrum antibiotic commonly used in clinical practice, cephalosporin itself has a good inhibitory effect on bacteria, from this perspective, taking cephalosporin for anti-inflammation is the right thing to do when you have pulpitis, but clinically, we should also explain to patients that taking cephalosporin can relieve the symptoms, but treating the symptoms is not the root cause. The fundamental solution is to find the cause of pulpitis, if the pulpitis is caused by caries, the decayed part should be removed and root canal treatment should be performed. If the pulpitis is caused by periodontal disease, in addition to root canal treatment, periodontal treatment is also needed, which is the root solution to cure pulpitis.
