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.
A RealAge answered. Composite resin dental fillings can usually be completed in one appointment, lasting up to an hour or so depending on the extent of the cavity. Getting a composite resin dental filling takes up to 20 minutes longer than for a silver, or amalgam, filling. That is because the tooth has to stay completely dry while the layers of composite are added to the tooth.
