Smoking is generally not recommended after tooth extraction, but if you can’t hold back a cigarette, don’t worry too much, just watch the extraction socket closely for bleeding and healing. Tobacco contains nicotine and other substances that can affect the healing of the extraction wound, so smoking is generally not recommended. Especially when the blood clot in the extraction socket is still unstable within 24 hours after extraction, premature smoking may lead to the risk of loosening of the blood clot and bleeding from the extraction wound, but this is only a relative risk, and does not necessarily occur in everyone who smokes after extraction. If there is no visible active bleeding from the extraction socket after not holding back a cigarette, there is no need to be overly concerned. If there is bleeding, it is advisable to visit the hospital promptly. It is important to note that smoking is detrimental to the healing process after an extraction as well as to your daily dental and physical health, so it is advisable to quit smoking as soon as possible.
