Dear Patient,Normally if proper approximation is achieved during primary closure and the wound closure has taken place ie after 40 days then there is no further need for for a flap surgery or Z-Plasty if the whole tooth has been removed. That will take care of the Oro-Antral Fistula.The pain and swelling is associated with the surgical part and shall dissappear within a week. Use cold fomentation along with the medicines prescribed to you by your dentist and wait.
