Thanks for asking the query,
Hydrocodeine is a narcotic analgesic
used to treat severe pain
and has antitussive action to treat cough.
If it is not working you can visit the Dentist
and get the prescription changed.
For relieving pain after surgery it will be better if you take anslgesics such as acecelofenac serratiopeptidase
combination which will be more effective.
Follow the post surgical instructions properly.
Use lukewarm saline and antiseptic mouthwash gargles twice daily.
Hope this helps out.
