White fillings have an expected life span of 7-10 years, and 10-15 years if Silver fillings. Vapeing can create an awfull lot of pain from just one single leaky filling. I know, because I went 3 days with no sleep from a sudden outburst of intense pain. Just takes a single leaky filling, to make a person feel like all there teeth are hurting. I have read many articles on people going thru this exact same experience, not knowing what is going on, even after they went too the dentist. I have read where people gave up vapeing, and went back to analogs, because of this exact problem. I was one of them people.. The cigs didn't hurt, not even pop, or candy or sugar in my coffee would hurt at all. My dentists did not seem to have a way to find the leakage, and I had always thought fillings were permanent, but they are not. For anyone that experiences such a thing, please do inventory on how old your fillings may be. I do believe a lot of people will benefit from this information.
