Excuse me. Is the Doctor in?
Good afternoon, sir. The Doctor is here today. Do youhave an appointment?
No, I don't. A friend of mine, Mr. Henderson, recommended Doctor Smith.
I want to make an appointment. My name is Mr. Turner.
I see. Wait just a minute. Doctor Smith, there's a patient here. He's a friend of Mr. Henderson.He wants to make an appointment.
I'm not busy now. Ask him to come in. Hello, my name is Doctor Smith. What can I do for you?
I have a tooth that's giving me trouble. It's this one, the upper front tooth.
When I close my teeth together it's rather painful. Pressure on it is very uncomfortable.
I can see that the gum is red and inflamed. There's also some swelling. When did you begin tohave pain?
It began with a very slight, dull ache about a week ago.
The X-ray shows that the area around the end of the root has become infected.
This tooth has had a root canal filling. Do you remember when it was done X?
It was about three years ago.
Well, sometimes a tooth that has been treated endodontically will become infected or develop acyst.
It doesn't always mean that the tooth will have to be extracted. It can usually be treatedsuccessfully by performing an apicoectomy.
What's that, Doctor?
Apicoectomy is the removal of a very small Part of the infected root tip.
Another Part of the treatment is to remove the infected (or cystic) tissue from the jaw-bonesurrounding the root.
And what is needed for this?
Sometimes a retrograde silver amalgam filling is needed to seal the small opening in the roottip to be sure that the tooth won't become infected again.
Can you please explain how this is done?
An incision is made in the gum just above the tooth at the level of the root tip.
After the infected root tip and infected tissue have been removed,
a small undercut preparation is made in the root for a silver amalgam filling.
It's done in the same way that a small cavity is treated on the crown of a tooth.
When can you do this for me?
I have time to do this now. I'm not expecting another patient for a little while.
Are you free? It shouldn't take more than 30 minutes
