By temporary filling, I am assuming he made temporary crowns for the front teeth.. If that's the case, then the swelling of the gums must be due to procedure done as well as the irritation from the margins of the temporary crowns or some excess cement which was used to fix the temporary crowns.. This will subside within a couple of days.. Till then you can apply Dologel CT to the swollen gums to aid in healing..

Dear practo user Please apply hexigel over the area for healing You can do some warm salt water gargling also. It will eventually heal, and you can go to your dentist for crown fixation. Discuss this when you visit for the crown
