The swelling of the face in toothache cannot be generalized and depends on the specific cause of the toothache. Generally speaking, if the swelling is caused by an acute inflammatory disease, the swelling will gradually go down after 3-5 days of treatment. However, if the swelling is caused by other types of diseases, the exact time of swelling reduction cannot be determined. Bacterial infection of the tooth or jaw bone tissue is a common cause of toothache, facial swelling and other adverse reactions. For example, pericoronitis, periodontitis, peri-maxillary abscess, etc. For patients with such conditions, the type of sensitive bacteria can be diagnosed by means of bacterial culture analysis, and then targeted antibiotics as well as other types of drugs can be used for anti-inflammatory and anti-swelling treatment. Commonly used types of drugs are levofloxacin hydrochloride tablets, ibuprofen extended-release capsules, ice boron containing tablets, etc. Usually the swelling can be reduced after 3-5 days of medication. However, for patients with other serious diseases such as periapical abscess, pulpitis, adenoma, etc., comprehensive treatment such as medication or surgery should be considered according to the actual type of disease of the patient. During the treatment period, patients should try to choose light and liquid food to reduce the impact of stimulation on the affected area, which can help relieve the discomfort and promote recovery.
