Same story as many, large filling fallen out, no treatment available. Dentist recommended filing down the sharp edges it left with a nail file (eeek!), and using a temporary filling for as long as it takes to be able to have it sorted properly.
I accept it's not going to be a permanent solution, I may have to redo it often, but every kit I've looked at has mixed reviews. Has anyone found one that's worked particularly well? (And I know that the kits are in short supply which doesn't help.)
