Dental crown
Dental Crown
A Dental crown is a type of dental restoration which completely caps or encircles a tooth or dental implant. Dental crowns are often needed when a large cavity threatens the ongoing health of a tooth. They are typically bonded to the tooth using a dental cement.
Types of Dental Crowns[edit | edit source]
There are various types of dental crowns, notably:
- Metal crowns: These include gold alloy, other alloys (for example, palladium), or a base-metal alloy (for example, nickel or chromium).
- Porcelain-fused-to-metal: This type of crown can be color matched to your adjacent teeth.
- All-resin: These crowns are less expensive but wear down over time and are more prone to fractures.
- All-ceramic or all-porcelain: These dental crowns provide the best natural color match than any other crown type and may be more suitable for people with metal allergies.
Procedure[edit | edit source]
The procedure for placing a dental crown typically involves a series of steps:
- The dentist prepares the tooth by removing its outer portion so the crown will fit. Any decay is also removed.
- An impression is made to provide an exact model for the crown.
- The impressions are sent to a lab, where the crown is made.
- During that time, you will have a temporary crown. These crowns are usually made of acrylic and are held in place using a temporary cement.
- The crown is cemented into place.
Risks and Complications[edit | edit source]
While dental crowns are generally safe, there are a few risks and potential complications, such as:
- Discomfort or sensitivity
- Chipped crown
- Loose crown
- Crown falls off
- Allergic reaction
Aftercare[edit | edit source]
After the procedure, it's important to look after your teeth to ensure the longevity of the crown. This includes regular brushing, flossing, and visits to the dentist.
