Check this post to understand why your dentist NEEDS to seat your crown perfectly to diminish the chance of open margins. Whether getting one crown or several in a row, working with a highly trusted dentist can make all of the difference.
Dental Crown:
When cavities overrun a tooth so much, the dentist will remove the decay and a crown becomes necessary. The dentist cements the crown in place to protect the existing tooth (and its neighbors).
A crown is a dental restoration that can:
- Protect a cracked or weakened tooth
- To replace a broken tooth
- Cosmetically fix a misshapen or discolored tooth
- Support a weakened tooth that has a large filling in it
In most cases, your dentist will prepare the surface of the natural tooth by making the tooth into a little mound (hill shaped). They’ll take an impression of your teeth, and place a temporary crown while customizing the permanent crown. When the permanent crown is ready, they’ll smooth the tooth surface, and fix the permanent crown in place with dental cement.
Open Margins:
In some cases, a gap will appear between the crown and the natural tooth surface. This is what is referred to as an open margin crown. The margin, or the area where the crown contacts the natural tooth, is not sealed, allowing food and bacteria to enter the space between the crown and the tooth.
This can be due to:
- A rough surface
- Uneven application of dental cement
- Other errors in application or crown manufacturing
In some cases, the crown itself is defective or ill-fitting and will never be able to be effectively sealed. This can be difficult to detect with the naked eye. A dentist who does not follow accepted protocols for checking fit or who rushes the process of making a mold of the teeth for the crown is more likely to miss any errors in fabrication, too.
Check bellow this case on an actual patient:
As seen on this case when cementing the final crown fitting was confirmed with X-Rays and patient had an open margin. We resubmitted case with new impression to the lab so assure the margins were perfectly closed and the crown was fully seated.
What Will Happen If My Dentist Doesn’t Make Sure My Crown Is Fully Seated?
Crown margin repair is essential for continued dental health. An ill-fitting or unsealed crown can cause future problems eventually leading to a root canal or extraction.
Open margins allow bacteria and food to be trapped underneath. Bacteria reproduces and a cavity is formed. In this case, the crown would be removed and the remaining tooth structure will have to be reevaluated. If the crown can’t be recemented correctly, new impressions will be taken and sent to the lab to fabricate a new crown.
If you are experiencing pain or any of those symptoms in the teeth you have your crowns or it’s simply time to replace them, be sure to ask Dr. Shurova at your next appointment. Call to schedule today!
