What are Dental Crowns and How Do All Work?
A dental crown is used when tooth decay is too extensive for a filling to cover. This type of restoration is also used to strengthen a tooth that has been weakened by a root canal procedure or to repair large chips or fractures. Sometimes crowns are used purely for cosmetic purposes to cover imperfections such as discolored or misshapen teeth. Also called a cap, a dental crown completely covers the tooth part that shows above the gums, fitting snugly along the gum line. Once firmly cemented in place, it functions just like a natural tooth.
What Makes Up A Dental Crown?
The dentists use dental crowns constructed from a variety of materials. Metal crowns, which are made from gold or other metal alloys, are durable and long-lasting. However, their conspicuous appearance makes them a better choice for molars or baby teeth. Porcelain-fused-to-metal (PFM) crowns consist of porcelain overlaying a solid metal substructure to combine both aesthetic appeal and durability.
PFM crowns do not appear as translucent as natural teeth and are best used on molars. All-ceramic crowns are the ideal choice for more visible teeth, as they are made from materials that are designed to match the exact coloration and clarity of your natural teeth. Reputable dental clinics offer durable and natural-looking eMax and zirconia crowns made from translucent ceramic materials. They also offer custom staining for all-ceramic dental crowns to maximize aesthetics.
How Are Crowns Placed?
The first step in placing a crown is for your dentist to numb the treatment area with a local anesthetic. Next, the dentist will prepare the tooth, which involves removing any decay present and then tapering the tooth shape so that the crown will adhere optimally. If your tooth is not very large because of breakage or extensive decay, your dentist may build up its structure with filling material and then shape it for a crown.
Next, the dental expert will obtain impressions of your mouth, which our excellent dental laboratory uses to create your custom restoration. While you are waiting for your permanent crown, he will wear a temporary one so that you can eat and function normally. In about two weeks, you will return to our office, where the dentist will remove your brief and cement the permanent crown to your prepared tooth, making sure that it fits well, looks great, and meets optimally with the opposing teeth.
