There are a number of reasons why your dentist might suggest the application of a dental crown. They are most often used in instances where a significant portion of the tooth has been lost, say to a cavity or breakage, but they may also be used for cosmetic purposes, such as to hide serious discoloration that cannot be corrected another way (like through whitening procedures).
Crowns could be made of materials like resin, porcelain, ceramic, and in some cases even stainless steel, although for cosmetic reasons, this last one is used less often. These materials will be bonded to teeth and molded to match your natural bite and create a pleasing appearance, completing your smile and restoring function.
How does the process begin? Your tooth will first have to be prepped to receive the crown, and this could include a number of steps.
Eliminating Decay and Infection
A healthy mouth is a prerequisite for many dental procedures, so if the reason you’re getting a crown has to do with a cavity, an abscess, or related issues, the first order of business is likely to restore your health before proceeding. This could involve removal of affected tissues and perhaps a round of antibiotics, depending on the situation. In cases of infection, further preparations for placing a crown may be delayed until you have completely recovered.
Tooth Reduction
In cases of tooth decay or trauma, preparations for placing a crown may start with removal of damaged tissue. Cavities, for example, will have to be removed before they can be filled, and a broken tooth might night to be shaped prior to placing a crown. In many instances, some amount of filing down is necessary, not only to accommodate the added bulk of the crown, but to prepare the tooth to properly bond with the tooth restoration.
Impressions and Fabrication
Once the tooth is prepped your dentist will take an impression and send it out to a lab so your permanent crown can be fabricated. A temporary crown will be placed on your tooth until your next visit, when the permanent crown will be affixed. Alternately, some dentists offer same day crowns, whereby your tooth will be digitally mapped and your crown will be created in-office and affixed during a single appointment.
Preparation for a crown may take some time or you could complete the entire process and leave the office with your permanent crown in place the same day. It all depends on the condition of your tooth and the services offered by your dentist.
