Is there a way to determine the age of fillings based on xray? I'm in a dispute with my dentist right now where I was billed for more teeth than he filled. He's claiming that the only way to prove this is to take an xray but my contention to that is that the extra teeth that were allegedly fixed had fillings in them already so even if an xray does show fillings in those teeth, they'd be from the past. I'm just not convinced taking an xray will show the age of a filling...any help is appreciated..
