I am having impacted wisdom tooth and cyst out 2moro general anthestic wil it be ok to have a smoke a couple of hours before, if not why? thanks

Not a good idea: The heat and chemicals of the smoke might irritate the open wound.

No: Smoking decreases your ability to clear mucous from the pulmonary tract by decreasing ciliary action ( small hairs that beat back and forth to sweep away mucous). It is best to refrain from smoking during the perioperative period (for several days before and after surgery). There are a variety of other reasons to not smoke as well. Smoking impairs healing and promotes infection. Time to quit!

No smoking: Smoking increases the risks of the anesthetic due to nicotine and carbon monoxide levels in the blood. Stopping 24 hours before your surgery increases oxygen and blood flow dramatically, which speeds healing.

Smoking b4 trtment: Smoking decreases the ability of the soft tissues of the mouth to heal. Introducing a strong irritant such as cigarette smoke just prior to tooth extraction is ill advised.
