It is recommended that you do not smoke after wisdom tooth removal until the extraction wound has healed. Smoking may lead to complications such as post-extraction infection, reactive pain, and dry socket, as described below. 1. Infection: Smoking will cause the temperature in the mouth to rise and produce tar deposits, which can cause poor wound healing and chronic infection, which may include wound discomfort, congestion, and purulent discharge. 2. Reactive pain: Smoking action can cause negative pressure in the oral cavity, resulting in blood clot detachment, exposure of nerve endings on the alveolar bone wall, and reactive pain after stimulation. 3. Dry socket: After the blood clot is dislodged due to smoking, the alveolar bone wall may have multiple small necrotic areas and dry socket occurs. If any of the above symptoms occur, it is recommended to go to the hospital in time to receive professional treatment as soon as possible.
