Swelling of the face after tooth extraction is mainly due to the oozing of tissue fluid. It is generally recommended to apply ice packs within 24 hours of tooth extraction, and hot packs can be applied after 48 hours, and non-steroidal anti-inflammatory drugs, such as ibuprofen, can be taken if necessary. The swelling of the face after tooth extraction usually begins 12-24 hours after the extraction of the tooth, and usually gradually subsides within 5-7 days. The swelling is loose and elastic, and the skin can be pinched by the fingers. 1. Within 24 hours of the onset of swelling, ice can be applied to the face as a cold compress to reduce swelling. After 48 hours, you can consider applying hot towels for localized warm compresses to help eliminate swelling. 2. Oral non-steroidal anti-inflammatory drugs can be taken to reduce swelling, such as ibuprofen, which can partially relieve pain. If the swelling of the face after tooth extraction is not eliminated for a long time, it is recommended to go to the hospital in a timely manner, and the use of drugs need to follow the doctor’s instructions.
