How to Speed the Healing Process After a Dental Surgery?

I had a dental surgery for exposure and bracketing of my impacted cuspid on saturday.The surgery area isn't swollen or painful but the wound isn't healed yet.I'm on a trip in 4 days and I want to know if there's any way to speed the healing process so that I won't have any problem there.Is there any way for the wound to heal quicker?

Suggestion:

start doing warm salt water rinses 4-5 times/day for the remaining 4 days.
this will increase the blood flow to the gums around the impacted canine and it will heal quickly.
keep the area clean with proper light brushing and mouthwash.
