So what are Dental Crowns and why would I need one?
Crowns are dental restorations that cover all the visible surfaces of a tooth.
Crowns are generally used for four dental purposes.
- They are used to restore significant tooth loss, usually resulting from deep decay (dental cavity) or the fracturing off of large potions of tooth structure.
- Crowns are used to treat teeth that are fractured in order to prevent the fractured portions from breaking away from the tooth and potentially causing further complications or to eliminate pain coming from the fractured tooth.
- They are made to protect molars from fracturing apart after a root canal is done on the tooth, a process that makes the tooth more brittle and thus more inclined to break.
- Crowns are also used to cosmetically alter a tooth or teeth, allowing for a different shape, color or position of the tooth being restored.
The process for making a crown usually involves two visits.
On the first visit, the tooth is prepared by removing diseased tooth and/or reducing tooth structure around the sides of the tooth and off the biting surface of the tooth in order to create space for the new restoration. This reduction permits the newly crowned tooth to be an ideal tooth size once the crown is seated. An impression is made of the prepared tooth and a temporary crown is fabricated and cemented. This visit is usually about 75 minutes long. At the second visit, the final crown is tried in and then cemented in place. This visit is usually about 30 minutes long.
