Thanks for asking the query,
As you mentioned you had four wisdom tooth pulled without any complications, i would advise you to follow the post operative instructions given by the Dentist
properly to prevent any further conplications and promote faster wound healing
can be due to the antibiotics and analgesics prescribed to you.
I would suggest you to take an antacid
like tab Rabeprozole 20 mg twice daily half hour before meal for five days.
If the antibiotics are causing discomfort, you can visit to the concerned Dentist and get it changed.
Hope this helps out.
