About 2 weeks ago I had 2 of my second molars extracted (bottom 2nd molars). Both of these molars had root canals done twice and infection returned after each treatment. Finally my dentist figured out that because of my severe jaw clenching at night I had managed to crack the root of both molars which explained why the root canals failed. I have noticed since the extraction that my right eye has had some "aura-like" spots obstructing my vision. I suffer from migraines and have had similar "aura-like" symptoms occur in both eyes while experiencing a migraine. This, however, is not connected to a migraine and does not go away like the migraine ones do. It's also alot more subtle then the migraine auras. Have you ever heard of symptoms like this after a dental procedure?? Should I be worried?
