A year ago my root canal filling fell off. How bad can it be now?

Hi,

Welcome to icliniq.com.

Let me start by telling you that if you have been to the dentist and sat through the root canal procedure then getting a filling should be a cake walk. Without a filling covering a root canal filled tooth, either the root canal will fail or the tooth might just breakdown. That is because a root canal filled tooth becomes brittle over time and having a filling gives it some strength. So, it is important that you get the tooth examined and filled as soon as possible. Let me also tell you that you could talk about your fear of dental treatment with your dentist and he or she could help you overcome those fears.
