I don't really have problems with the stability of the root canal tooth I am only worried because I had a few strange symptoms since the latest one. They are tingling sensations around the heart area (if that is a description) and I am worried after reading what kind of proplems can be accociated with root canals. And how can I know if they have been done properly? But dental implants seem to be safer than the root canal acording to your information?
