All I'm trying to do is figure out the heighth of the platform I will need to build to install a new shower stall. Oh and Marlin, I said that a hole was not an option for many reasons. Number one on that list is not wanting to turn a $3,000 job into a $30,000 job.
In brief: Generally.. As far as the filling itself goes, you can eat right away with tooth colored composite fillings, but should wait at least one hour with amalgam (silver) fillings. It's always best you ask your own dentist as this can vary somewhat based upon the size and location of the filling.
Most composite resin fillings will last at least five years or more before they need replacing, and can be used to repair areas of decay and damage to both front and back teeth. Inlays. Dental inlays are used to repair areas of decay in the chewing surfaces of the back teeth. Your dentist will recommend an inlay over a conventional dental filling if the area of decay is quite large.
