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.
Flat top 15 and 16 oz cans came into use starting in 1953 so a flat top 16 oz can would date between 1953-1964. Krueger Brewing made the only 16 oz cone top in about 1940. The beer cone top is very scarce. The ale was a tough can until a couple hundred were found in a barn in Vermont.
