In brief: Wrong question. If you received a local anesthetic for extraction of wisdom teeth, you will be numb for 1-2 hours afterwards. General anesthesia (going to sleep) is also administered in come cases of wisdom tooth extractions but usually does not cause numbness of any part of the body.
In 1876, Charles Hires first sold commercial root beer to the public.
Root beer was originally derived from sarsaparilla or sassafras root, giving it its name and its signature flavor. It has a darker color like a cola, but unlike many regular colas on the market, root beer is generally caffeine-free. However, not all root beer brands skip out on caffeine.
