Good morning Mrs. Hall. If none of your teeth are bothering you, I'll restore the tooth with the largest cavity.
霍尔太太，早安。 假如你的牙齿不让你难受的话， 那么我就把蛀的最厉害的牙补一补。
This is the tooth that I'll treat today.
It would be best to use a silver amalgam restoration (filling) here.
The cavity is deep so we'd better use a local anesthetic. Is that OK with you?
蛀牙的洞太深了， 还是做局部麻醉好。 你看这样好不好？
Yes, go ahead, if you think that an anesthetic (novocaine) is necessary.
I don't like to have an anesthetic for small cavities.
The sound and vibration of the handpiece (drill) bother me.
What can you do about my chipped front tooth?
That tooth needs a porcelain jacket or a ceramic veneer crown.
I can't put in another silicate (synthetic porcelain) or plastic restoration because it wouldn't be strong enough.
When a Part of the biting edge of a tooth is lost, a stronger restoration is usually needed.
What type of restoration do you use，Doctor?
Either a gold inlay or a crown.
A crown would look much better.
I don't think that you'd like to have gold showing from a front tooth.
We can start now. It shouldn't hurt. Please tell me if it isn't anesthetized (numb).
The decay was very close to the pulp.
What will you do for that?
I'll put a special covering over the deepest Part of the cavity to protect the pulp.
It has calcium hydroxide in it. It will help to protect the pulp from injury.
When a cavity is as deep as this one is, there's a chance that the pulp will die at some time in the future.
