I had a filling last October in my upper left premolar teeth. It came off yesterday suddenly and I can feel the gap in the teeth with my tongue. There is not much pain as I've been used to the pain by now. I always rinse my mouth and brush my teeth so that nothing gets stuck in there. Do I need to visit the dentist and get it filled again? I'm skeptical of visiting dentists here in Canada as they charge a lot of money and tells us to do extra tests and things. I had problem with 1 tooth but they wanted to do full mouth xray and cleaning and everything. I would have been okay with these if the charges were reasonable but it's too high and is not covered by ohip also.
