Doctors recommend not to smoke whether the tooth is extracted or not. Of course, smoking after tooth extraction has a negative impact on the teeth mainly including wound healing and local inflammation due to tooth extraction, so smoking has a negative impact on the oral mucosa, teeth, and the dental bed itself. If we speak from the doctor’s point of view, it is considered that smoking should be quitted as early as possible, regardless of whether it is due to tooth extraction or not. In addition, if you go back to smoking after tooth extraction, the direct stimulation of tobacco will cause the oral wound to be difficult to heal, and the surrounding inflammation will be aggravated, and even the long-term stimulation of tobacco, especially for the wound, will cause tissue mutation and even genetic mutation, which may induce the occurrence of cancer, so you should pay attention to smoking as little as possible and quit smoking as early as possible.
