The crown of the tooth is the part of the tooth that is visible above the gumline. It is covered in enamel. When part of the crown is broken, chipped, cracked, or eroded, it can be artificially replaced through a crown restoration procedure. This procedure is carried out at Peninsula Family Dental Center. They are important when the mesial and marginal ridges of the tooth are missing, the lingual or buccal walls are eroded, or the entrance cavity in a root canal procedure is greater than one-third of the occlusal surface of the tooth.
Types of Dental Crowns
Dental crowns come in different materials. They can come in the form of stainless steel, porcelain or ceramic, composite resin, gold alloy, zirconia, porcelain fused-to-zirconia, or porcelain-fused-to-metal. Stainless steel crowns are the preferred choice for baby teeth. Gold crowns are the most durable crowns. They are also a good choice for patients with bruxism because of their strength. Porcelain crowns blend with the natural teeth the best and are the best choice for front teeth. Porcelain-fused-to-metal crowns provide the strength of the metal placed inside and the aesthetics of the porcelain placed over it. The main constituent of zirconia crowns is zirconium, which is metal similar to titanium. Zirconia crowns are strong and are also aesthetically pleasing.
Crown Restoration Procedure
The crown restoration procedure involves two visits to your dental office. The first visit is for preparing the tooth, and the second visit is to place the permanent crown. At the first visit, our dental professional takes a radiograph of the tooth needing a crown to examine it. Our dental professional also checks for the likelihood of potential infection and discerns the need for a root canal treatment. The presence of extensive decay is also assessed. Next, a local anesthetic is applied to numb the tooth and the surrounding gums. The tooth is reshaped. The occlusal surface and the sides are chiseled to fit the incoming crown. If the area of decay or damage is large, a dental filling might be added to support the crown. That process is known as a build-up. Impressions are then taken of the tooth receiving the crown using an impression material. The impression can be made manually or using a digital scanner. In order to avoid altering your bite, an impression may also be taken on the teeth above or below the tooth receiving the crown. A temporary crown is temporarily cemented to cover the already prepared tooth.
If traditional impressions are taken, they will be sent to the laboratory. If a digital scanner collects the information, it sends details of the impression to the laboratory where the permanent crown is made. If needed, our dental professional also sends the laboratory technician the shade of your teeth. If applicable, the permanent crown is manufactured with materials that can blend with the color of the neighboring teeth. At the second visit a few weeks later, the permanent crown is placed over the prepared tooth using a permanent cement.
Dental crowns help restore the morphology and functionality of damaged teeth. They can also improve aesthetics. In addition, they can serve as the crown on the visible part of dental implants. They are also used to enhance and strengthen teeth that have undergone a root canal treatment. To reach Peninsula Family Dental Center for your tooth restoration, please call (907) 283-9125 today.
