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 composite (tooth colored) filling is used to repair a tooth that is affected by decay, cracks, fractures, etc. The decayed or affected portion of the tooth will be removed and then filled with a composite filling. Composite fillings are widely used today. Because composite fillings are tooth colored, they can be closely matched to the color of existing teeth, and are more aesthetically suited for use in front teeth or the more visible areas of the teeth.
