What is the chance of the pulp dying，Doctor?
You can't be absolutely sure in these cases，but I'm very confident (sure) that everything will be OK.
When the pulp of a tooth dies as a result of a deep cavity, the tooth will become infected.
What happens when a tooth is infected?
A toothache or swelling will eventually develop in a tooth that's infected.
A tooth might become infected many weeks or months after the decay has been removed.
Would there be any pain?
There might not be any pain if the infection is mild or if it finds a way to drain (if a fistula develops).
假如感染轻微的话， 或者找到引流的通道的话， 就不会疼。
If the infection doesn't put pressure on a nerve there won't be any pain.
Sometimes my tooth is sensitive to cold.
I'll put a lining under the amalgam to insulate the tooth against sensitivity to cold.
As you know, large fillings are sometimes sensitive to cold because metal is a good conductor of temperature changes.
The tooth may be sensitive to hot and cold foods for a while in spite of the insulation.
Don't worry; the sensitivity will disappear in a week or two.
Close your teeth gently. Does the filling feel high?
It feels fine.
Now tap your teeth together and slide your jaw from side to side.
Good. That's it. The filling is finished.
好。 就是这样， 补好了。
Thank you, Doctor.
Don't chew on that side of your mouth for at least 8 hours. That will give the filling a chance to harden.
I'll polish it during your next appointment.
As I said before, there's a small chance that the pulp will die because of deep decay.
就像我先前所说， 因为蛀牙洞深了， 牙髓还是有坏死的可能。
If you get a toothache in that tooth we can still save it by doing a root canal treatment.
Don't worry. I don't think that you'll have any trouble.
