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.
Tooth Sensitivity after Composite Fillings. I always tell my patients that any time a tooth is drilled on, there is potential for some post operative sensitivity. The more work the tooth requires, or the deeper the cavity, usually results in more sensitivity. The range of sensitivity is different for every patient. In a normal-small to moderate size filling, sensitivity to cold temperatures usually subsides within a couple of weeks.
