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.
Hyaluronic acid fillers tend to be the most temporary option, and therefore are often recommended for first-time filler patients. These will typically last from 6 to 12 months, depending on treatment. For example, injections to the lips will wear out a little faster than those to the nasolabial folds.
