Thanks for posting your query,
After dental surgery detailed post operative care should be taken to avoid complications like swelling , pain and any chance of getting infections . As the dental surgeries are long and traumatic it is natural that you get the above symptoms . Generally swelling after Dental surgeries starts after 24 hours and lasts upto 7-10 days .
Follow the post operative instructions properly . Take the complete course of antibiotics and analgesic
. Do regular rinsing with lukewarm water , use of antiseptic mouthwash helps in preventing infection and promotes healing.
Take vitamin suplements . Application of cold
packs on the area can be effective, take some ice cubes in a towel and apply it over the swollen area for atleast 10 minutes , this will help to reduce the swelling .
If the ssymptoms persists visit to your dentist
and get checkup done.
Hope this helps out.
