You should have received specific instructions from the oral surgeon who removed your teeth. Including proper cleaning of the sutures (i.e. rinsing with salt water) - with instructions of seeing him back if you have things that indicate infection - again these instructions should have been provided to you after the surgery.
A question - were you under anesthesia? Most do this for removal of wisdom teeth - if that was the case you should have had a friend or family member with you - they may have the instructions.
In any case - you should contact your oral surgeon. Whenever you have any procedure if something does not seem right - unusual pain or anything else - you should contact them.
