One week after multiple tooth extractions. no complications so far. am i in the clear? if not what can i do to prevent complications at this point?

Sounds good: Your initial healing is well underway so sounds like clear sailing.

Probably OK: What you can do is keep mouth immaculately clean via BOTH brushing and flossing. See Dentist regularly for examinations and professional cleanings. Talk to your dentist about advisability of replacing the extracted teeth. Do not abuse Alcohol. Don't smoke anything. eat a healthy well rounded diet.
