What's a dry socket?
 

it deals with pulling out teeth

You dont want one, they hurt bad.

Its after you have a tooth pulled air gets up in it and the nerve and stuff drys out.

Thats why they say dont suck on a straw or smoke after you have a tooth puled cause it prevents the blood from sealing and clotting.

yes if you smokeafter gettin a tooth pulled it can kill you
