dear friend.
thanks for sharing your concern.
Dry socket is a painful condition post extraction
I can recommend you the treatment modalities followed for dry socket but are you comfortable applying it on your own in the socket?
i mean post extraction evaluation is a part of treatment,which is carried out by the same
dentist.
therefore i would suggest you to revisit your dentist if possible.
anyways, for your dressing i can say this.
you can slowly and carefully debride the socket with warm normal saline,do this twice.
After that, take a small gauze piece on which you can put iodoform paste OR zinc eugenol paste and slowly place it in the extracted socket.
Place it loosely and not very tightly in the socket.as it will get hardened and difficult to remove later.
Dressing is given first 24 hours,then every alternate day,then every 3 to 4 day ,then on weekly basis it is done.along with this take analgesics also for first three days if required.
hope it helps.
thanks
