Hi , I was flossing for the first time after my fillings done one month before. Actually i got my wisdom tooth heavily filled and there was some execcsive amount of filling came in between of my 2nd molar tooth which was cut out and fall out while i was flossing . It was just the extra part i don't have any pain.But I'm scared because its been a one month and filling was hardened and also when i checked that filling part it was not strong i was able to break into pieces using my nails. I got my other teeth filled with same material that GIC 3M Ketac i believe. I'm thinking then how durable is it on my other teeth i got 4 more.pls suggest
