Dental Crowns and Bridges
There are two types of dental restorations used to repair and replace damaged or missing teeth. Both treatments aim to improve oral health, restore function, and enhance the appearance of the smile.
Dental Crowns
A dental crown, also known as a cap, is a restoration that covers a damaged or decayed tooth to restore its shape, size, strength, and appearance. Crowns are custom-made to fit over the entire visible portion of the tooth.
Indications for a Crown:
- Protecting a weakened tooth from breaking.
- Restoring a tooth that is already broken or severely worn down.
- Covering and supporting a tooth with a large filling when there isn't much tooth structure remaining.
- Holding a dental bridge in place.
- Covering a dental implant.
- Improving the appearance of a discoloured or misshapen tooth.
Materials Used:
(1) Porcelain or Ceramic: These materials closely resemble natural teeth in color and texture, making them a popular choice for front teeth.
(2) Metal Alloys: Crowns made from metal (such as gold) are strong and durable but may be less aesthetically pleasing.
(3) Porcelain-Fused-to-Metal: This type combines the strength of metal with the natural appearance of porcelain.
Procedure:
- The tooth is prepared by removing a portion of the enamel to make room for the crown.
- Impressions are taken of the tooth and sent to a dental lab, where the custom crown is made.
- In the meantime, a temporary crown may be placed to protect the tooth.
- Once the crown is ready, it is fitted and permanently bonded to the tooth.
Dental Bridges
A dental bridge is a restoration used to replace one or more missing teeth. It consists of one or more artificial teeth (pontics) held in place by crowns (abutments) on the adjacent teeth.
Indications for a Bridge:
- Filling the gap left by one or more missing teeth.
- Restoring the ability to chew and speak properly.
- Maintaining the alignment of surrounding teeth.
- Improving the appearance of the smile.
Types of Bridges:
(1) Traditional Bridges: These consist of one or more pontics held in place by crowns on the adjacent teeth.
(2) Cantilever Bridges: These are supported by a crown on only one side of the pontic.
(3) Maryland Bridges: These use a metal or porcelain framework bonded to the back of adjacent teeth, minimizing the need for crown preparation.
Procedure:
- The adjacent teeth are prepared to support the crowns that will hold the bridge in place.
- Impressions are taken and sent to a dental lab, where the custom bridge is made.
- A temporary bridge may be placed until the permanent bridge is ready.
- Once the bridge is ready, it is fitted and bonded to the adjacent teeth.
Aftercare
- Oral Hygiene: Good oral hygiene practices, including brushing and flossing around the crown or bridge, are essential for maintaining oral health and longevity of the restoration.
- Regular Check-Ups: Regular dental visits will help ensure your crown or bridge remains in good condition and any issues are addressed promptly.
Both dental crowns and bridges can significantly improve your oral health and the appearance of your smile. Your dentist can help determine which option is best for your specific needs.
