There is no direct relationship between the absence of pain after wisdom teeth extraction and the possibility of dry socket syndrome. If there is a secondary infection, it may cause dry socket syndrome, but if there is no infection, generally do not get dry socket syndrome. Dry socket syndrome is a complication caused by tooth extraction. If acute infection occurs in the wound after wisdom tooth extraction, severe pain in the alveolar fossa will generally occur 3 to 5 days after extraction and radiate to the surrounding area. If there is no pain after wisdom tooth extraction, and if there are no uncomfortable symptoms for more than a week, you will generally not get dry socket. The cause of dry socket syndrome is complex and has not been fully elucidated. It may be related to the trauma of the surgery, bacterial infection and other factors. No pain after wisdom teeth extraction, no other discomfort, generally do not need to worry and special intervention, pay attention to oral hygiene, prevention of infection, uncomfortable symptoms, as soon as possible to seek medical attention.
