When can I drink alcohol after having wisdom teeth extraction?

Wait a week. You may have been given medication for pain or an antibotic. These medications don't mix well with alcohol. Also after anextraction, you have an open wound, alcohol would burn and delay healing.
Wait at least 1 week. You probably will be recovering from sedation and you may be on strong narcotic pain medications. Having alcohol in the mix is dangerous. Also, alcohol delays healing.
