Good morning, it's nice to see you again, Mrs. Walsh.
Hello, Doctor. That extraction has healed very well. I had no trouble with it.
Good. You should have a bridge to replace that missing tooth.
Do you think that it's absolutely necessary?
Yes, I do. If a bridge isn't made, the two teeth next to the space may move and tip over (tilt).
If they’re not held in a normal position they may be lost prematurely.
How can teeth be lost because they move?
Teeth that have moved may be lost because of abnormal biting pressures.
They destroy both the tissues that surround the tooth and the tissues that hold the tooth securely.
The upper tooth that was biting against the missing lower tooth will drop downward, because there's nothing below it to hold it in place.
As a result, you might lose the upper tooth.
I see. How do you make a bridge?
I'll make two gold crowns (caps) on the two teeth on either side of the empty space.
Then, I attach the missing tooth (pontic) to the crowns.
I really don't want to have gold teeth.
Don't worry. There will be tooth-colored porcelain covering the front of the bridge. This will make it look natural.
What do you do to prepare the teeth for the crowns?
When I prepare the teeth for the crowns, they look like this model.
The next step is to make an impression of your teeth.
A model like this one is made from the impression with plaster.
