my top ones grew out sides of my jaw no room, the bottom one were impacted.. i had all 4 removed and i was put under.. had no complications at all. just bruising on my face.. no antibiotics to take. a friend had a dry socket that was nasty to treat.. id opt to be put under. u dont know how deep some of those roots r and it can take alot of effort to get some teeth out and the bleeding can be extensive if the roots r really deep or wrapped around the roots of other teeth.. the molars have more then one root each and can go pretty deeply into the jaw.. took like 20mins tops for mine to be removed..
