After dental implant surgery, it is recommended that you take it easy for 48-72 hours.  Resting assists the healing process and limits post-surgery bleeding.  Drink plenty of fluids, but nothing of extreme temperatures.  You may need to apply an ice pack to your face in twenty-minute intervals for 2 days following surgery.  If you receive upper implants, do not blow your nose for two weeks.  It is common to experience slight bleeding for about 2 days after surgery.  You will feel slightly uncomfortable the first 2 days following surgery, but the third day is generally better.  An increase in temperature of about 1 to 2 degrees is to be expected and is not a cause for concern.  Finally, while you can eat when you are hungry, do not chew directly onto the bone graft.
