Thanks for asking the query,
If you have done with molar extraction and if pain becomes intense and doesnt go away in few days it may be a sign of dry socket , in this condition the blood clot gets dislodged leaving the bone exposed to air . It is a very painful condition often associated with bad breath and fever
ciggarette will delay the wound healing and increase the chances of getting dry socket, complete wound healing after extraction takes at least 3 months .
I would suggest you to quit the habit for atleast 3-4 months .
It is my wise advise to you to leave the habit forever as it may cause many health hazards...
Take tab ibuprofen
twice daily .
Visit to your Dentist
and get the checkup done , he can clean the socket remove the debris and place a dressing of zinc oxide
to promote healing . you probably have to come back to Dentist after sometimes to change the dressing.
At home take saline water gargles 3-4 times , use antiseptic mouthwash gargles twice.
Follow the post extraction instructions properly.
Hope this helps out.
