A toothache with a small abscess on the gums is a symptom of periodontal abscess or alveolar abscess, which requires periodontal treatment or root canal treatment; medication cannot cure the above symptoms. Commonly used drugs to assist in the treatment include cefaclor, ornidazole and so on. 1. Periodontal abscess: it is a complication of periodontitis in the advanced stage; its main symptom is the formation of limited abscess (i.e., gingival abscess) in periodontal tissues, accompanied by severe pain and tooth loosening; periodontal treatment, i.e., calculus scaling and abscess incision and drainage, is necessary to effectively alleviate the symptoms. 2. Alveolar abscess: caused by periapical tissue infection, its main symptoms include tooth bite pain, gingival fistula (i.e., gingival abscess) and pus overflow, etc.; need to carry out endodontic treatment, to remove the inflamed and necrotic pulp tissues in the root canal. It is recommended to seek medical attention for symptomatic treatment of the above symptoms. If the symptoms cannot be treated in time, oral anti-inflammatory drugs (e.g., cefaclor, ornidazole) or painkillers (e.g., ibuprofen) can be prescribed to temporarily relieve the symptoms.
