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.
If you have natural teeth that are not healthy enough to keep, you will need to have them removed before you can be fitted for dentures. Once your teeth are removed, you will generally have to wait about four weeks before getting complete dentures. After your mouth heals, your dentist will take impressions of your mouth, design the dentures, have you try them on, and then finally give you the completed dentures. After several weeks, your dentist will have you come in to make sure you're adjusting well and the dentures fit properly.
