Thanks for asking the query,
From your description it is not clear what type minor surgery you have undertaken.
I would advise not to take more then one tablet of dispirin in one day.
Please take the medications as described to you.
Also get a course of antibiotics and analgesics prescribed to you by your Dentist
At home take lukewarm saline and antispetic mouthwash rinses.
Maintain a good oral hygiene
Avoid eating of hot and spicy foodstuffs.
and consumption of alcohol.
Hope you find this as helpful,
