Dental Crowns
A dental crown is a tooth-shaped cap that is used to restore a decayed, broken, weak, or worn-down tooth. Dentists may also utilize crowns to cover dental implants and root canal-treated teeth. These crowns are typically made from various materials, such as metal, resin, or porcelain, and can last anywhere from five to 15 years when properly cared for.
Dental Crowns Procedure
During the dental crowns procedure, the following steps are typically involved:
Examination and Preparation: Your dentist will examine the affected tooth to determine if a dental crown is the appropriate treatment. If deemed suitable, the dentist will prepare the tooth by removing any decayed or damaged areas.
Tooth Impression: An impression of the prepared tooth and surrounding teeth will be taken to create a custom-made dental crown that fits perfectly in your mouth.
Temporary Crown: While the permanent crown is being fabricated in a dental laboratory, a temporary crown will be placed over the prepared tooth to protect it.
Crown Placement: Once the permanent crown is ready, your dentist will remove the temporary crown and fit the new one onto the prepared tooth. The fit, shape, and color will be checked to ensure it blends naturally with your other teeth.
Bonding: The dental crown will be bonded into place using a dental cement, ensuring a secure and long-lasting fit.
Bite Adjustment: Your dentist will check your bite and make any necessary adjustments to ensure that your new crown functions properly.
Final Polishing: The crown will be polished to give it a smooth and natural appearance.
Types of Dental Crowns
There are several types of dental crowns, each made from different materials. The most common types of dental crowns include:
Porcelain Crowns: Porcelain crowns are popular for their natural appearance and ability to blend seamlessly with surrounding teeth. They are a good choice for front teeth and are suitable for patients with metal allergies.
Ceramic Crowns: Similar to porcelain crowns, ceramic crowns offer excellent aesthetics and are often used for front teeth restorations. They are more resistant to wear compared to porcelain.
Porcelain-Fused-to-Metal (PFM) Crowns: PFM crowns have a metal substructure covered with a layer of porcelain. These crowns provide both strength and a natural appearance. However, a small dark line may be visible at the gumline due to the metal beneath the porcelain.
Metal Crowns: Metal crowns, such as those made of gold, silver, or other alloys, are highly durable and resistant to wear. They are commonly used for molars and premolars, where aesthetics are not a primary concern.
Zirconia Crowns: Zirconia crowns are known for their exceptional strength and durability. They are a great choice for both front and back teeth restorations.
Composite Resin Crowns: Composite resin crowns are made of a tooth-colored material and are typically used for temporary or short-term restorations.
