[|Human|] I had my pre-molar root canal procedure and the temporary filling fell out in small pieces even the food was chewed in the unaffected site.  Ive had no pain and felt a hole of my root canal tooth exposed. Could you please tell me why the filling came out?
[|AI|]  Hello, thank you for asking your query with ChatDoctorAs you are mentioning that a root canal treatment was done in premolar tooth and the filling fell now, it can be possible. Actually when a root canal treatment is done the tooth becomes brittle and the crown of the tooth is also grossly decayed so very less support is there for the filling that is why it has fallen.In my opinion you should go for crown placement on the tooth which will support the filling and protect the tooth from further infection. So you should visit your dentist for the crown. Regards
