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.
As a natural way of cleansing the tooth socket, the body will send more blood to the wound site, triggering bleeding after the performed surgery. Depending on how difficult was, the amount of blood secreted may vary. However, blood clot should be promoted within 24 hours after the surgery. Your dentist will ask you to bite a cotton pad on gently within first few hours to promote blood clot. On the first day, swelling and pain might still be excruciating, causing extreme discomfort while eating, even talking and opening the mouth.
