yes, root canals must be pulled if one wants good health. we give you a temporary partial to wear for 2 to 3 months, then you can get a permanent bridge. we would do a Maryland bridge, in which we do not have to grind down the two teeth beside the missing tooth. it is a fixed bridge. you can still have the veneers there. we may need to replace those veneers if they have metals in them. to know if the veneers are toxic, you need to get an MSDS (materials Safety Data Sheet) on them. the dentist who did them will have one. or, you can find out the brand name of the veneers and i can try to find an MSDS. if they do not contain metals or endocrine disruptors, then i would suggest you get a biocompatibility test if you are still concerned if they are affecting your health in any way.
