Welcome to HCM
I would like to tell you that wisdom teeth extraction is not a simple extraction.Its somewhat complicated surgical procedure & there are many post extraction effects that are seen like:-
due to local anaesthesia effect
-difficulty in opening mouth
You don't need to worry for any of these symptoms. Get your stitches removed after a week.
Take some rest & start with amoxiclav-625 twice a day along with zerodol-SP twice a day.Also take some multivitamin
20 mg if acidity persists.Take all this for 5 days.
Along with that start warm saline rinses 3-4 times a day & betadine
