I have a couple of questions I'm hoping you could answer:
Are there ever circumstances where it's desirable to take bite wings more frequently than once a year?
I ask because I have a lot of older fillings, and all of my recent dental issues stem from the fillings leaking - (I am assuming the decay has a head start in this situation, so there is less time to catch it before needing root canal treatment).
Also, could you tell me how long a filling typically lasts before it starts leaking? Are there different durations for resin and silver filling?
Thank you for your time, it is appreciated.
