What Are Dental Crowns?
A dental crown is a tooth-shaped cap that is placed over a damaged or weakened tooth to restore its shape, size, strength, and appearance. Crowns are a versatile solution for a variety of dental issues and can help preserve your natural tooth structure while improving the overall function of your bite.
When Are Dental Crowns Needed?
Dental crowns are commonly used in the following situations:
- To Protect a Weak Tooth: Crowns can prevent a cracked or decayed tooth from breaking further.
- To Restore a Broken or Worn Tooth: They can rebuild a tooth that has been severely worn down or broken.
- To Cover and Support a Tooth with a Large Filling: Especially when there isn’t much tooth structure left.
- To Hold a Dental Bridge in Place: Crowns are often used to anchor a bridge that replaces missing teeth.
- To Cover Misshapen or Severely Discolored Teeth: Crowns provide a natural and uniform appearance.
- To Cap a Dental Implant: A crown is placed on top of an implant to replace a missing tooth.
- For Cosmetic Enhancements: Crowns can improve the appearance of a tooth.
The Dental Crown Procedure
- Initial Examination: Your dentist will assess your tooth and may take X-rays to determine if a crown is the best solution.
- Tooth Preparation: The tooth is reshaped by removing a portion of enamel to make room for the crown.
- Impressions: Impressions of your teeth are taken to create a custom-fit crown.
- Temporary Crown: A temporary crown may be placed while the permanent crown is being crafted in a dental lab.
- Crown Placement: Once ready, the permanent crown is cemented onto your tooth and adjusted to your bite.
