What’s a crown? for the dentists out there?

It is a porcelain shell that covers your tooth.

Answer:
A crown is the same thing as a cap. Just different terminology. It is custom made to fit your tooth that has been shaved down. They’re usually made out of gold, with porcelain baked on. If you’re having the crown put on a molar, it is always advisable to go with a gold crown, as gold is the strongest material and will not break.

Sometimes, on front teeth, an all porcelain crown is used.

The reasons patients need crowns vary. It can be due to having root canal treatment, or that the tooth has fractured, or that the tooth has weakened due to decay and huge fillings. Crowns are used to keep the tooth structure together and strengthen the tooth.

You must be diligent about keeping them clean. Make sure to floss around the crown everyday. Decay under a crown cannot be seen by x-ray, so, often it is not detected until it is too late.

Answer:
I got my first one a couple of months ago. A tooth with a filling cracked and upon removing the filling, there wasn't enough good tooth there to re-fill. So they put a “crown” on it (think of a crown like royalty…something that goes on top of something). They made an impression to see how my upper teeth met my lower teeth, and constructed a “crown” (fake tooth) to go over what was left of the old, cracked tooth. Now I have a full sized tooth again (or the appearance of), instead of part of a tooth due to some of it breaking off.

You can look up dental crowns online. I'm not sure if they are all made of the same material or not. I would imagine you can also find pics. Make your search engine your best friend. ☺

Answer:
when the tooth is broken or decayed then the tooth is reduced and a cap is being put on top of the reduced tooth carved into the shape of the particular tooth.
