You don't really feel the filling and when the tooth comes out, the filling comes out with it. It is just like part of the tooth! HAPPY SEARCHING CHUMS:D!
About three hours, just to be safe.
You should get another filling
It depends what sort of filling and what anesthetic you had. If it is the tooth-colored one then you are good as soon as the UV light sets it, if you have the silver colored filling then it is best to wait 24 hours to eat on that side of your mouth.
Usually after a tooth has a filling put inside the pain will calm down. Sometimes the tooth will be more sensitive and painful for a few days after having a filling put in.
AS SOON AS THE NUMBNESS WEARS OFF, USUALLY 3-4 HOURS AFTER
Its basically a large filling. A three surface filling can be described in example as "MOD Filling" which would the the mesial, occlusal, facial surfaces, if indeeed, that is the 3 surfaces the filling is going. Mesial and distal represent the different sides of the tooth, and occlusal is the top - center surface of the tooth. So MOD would be a filling ranging across the top of the tooth. The entire top wont be gone, but there will be a noticable filling.
it is most likely the tooth had a small crack in it anyway. the tooth was alittle"high"from the new filling and the extra pressure from biting on it, cracked the tooth. usually after a new filling, you should go back to have the filling polished which strengthens the filling and adjusts the bite.
needs to be smoothed.
get it refilled
It is best to wait until the anesthetic wares off( if you have it). Your dentist will probably tell you not to eat for a while sot it gives the filling time to set probably. When you do eat, the tooth with the filling will probably be sensitive to hot or cold things.
The whole is most likely from a cavity so they will put a filling in it. Most likely the dentist will get you numb. When you are numb they will drill out any decay and then shape the whole so it will hold a filling properly. If it is a front tooth, you will get a tooth colored filling. If it is a back tooth, you could get a silver filling or a tooth colored filling. That depends on your insurance, the docotor and you. If you have more questions, the dentist should answer any of them before beginning the work.
