Swelling after extraction of blocked teeth usually disappears in about 3~5 days, the specific time of disappearance is related to the state of the tooth before extraction, the individual’s physical condition and the degree of local trauma. 1. Status of teeth before extraction: If there is no infection and inflammation reaction in the teeth before extraction, then the swelling after extraction of blocked teeth will generally disappear faster, and it will disappear in about 3~5 days; on the contrary, the time may be relatively longer. 2. Individual physique: If the individual is in good physical condition and recovers quickly, then it may only take about 3 days for the swelling to subside; if the physical condition is usually poor, and no attention is paid to postoperative oral care during the extraction period, it may lead to a relatively longer period of swelling and even infection. 3. The degree of local trauma: if the wound left after the extraction of the blocked tooth is relatively small, the swelling can be eliminated in about 3 days; however, if the wound itself is relatively large, it may take 5 to 7 days for the swelling to disappear. It is recommended that once patients find themselves swollen after extraction of blocked teeth, they should seek timely and complete relevant examinations and standardized treatment to avoid more serious complications such as sepsis.
