Dental crowns repair and protect smiles in Paxton, MA
If your dentist has recommended that you get a dental crown placed on a tooth, you might be wondering why one is necessary and the process for getting one placed. Below, Dr. Scott Siemen, dentist at Paxton Dental Care in Paxton, MA, explains what you need to know about dental crowns.
What is a dental crown?
A dental crown, also commonly referred to as a tooth cap, is a dental restoration that is designed to restore the natural shape and function of a tooth that is decayed or has been damaged. It is a tooth-shaped piece of material (typically a durable dental porcelain for a natural appearance) that covers the entire surface of a tooth.
Dental crows are an ideal solution to retake your smile back from dental damage or decay!
When we see a black line near the pink gum line surrounding a crown, one of the reasons maybe that a porcelain fused to metal crown – PFM was used to restore the front tooth. PFM crowns have a metal alloy as a base, and are layered with porcelain on top. These types of crowns will often have a metal margin that presents a dark grey or black line. The only way to remove this is to redo the crown with an all porcelain material that will be very cosmetically pleasing. After being made comfortably numb the existing crown is skillfully removed without damage to the underlying tooth. The tooth preparation is cleaned of any cement from the previous crown and any decay at the margins is removed. A new impression is taken. A temporary crown is then placed on the tooth and the new impression is then sent to the dental lab for fabrication of a custom porcelain crown. At your second appointment the temporary is removed. The final porcelain crown is then seeded on the tooth the patient is then ready to smile with confidence with no metal margin showing on their crown.
Why a dental crown may be recommended
Dental crowns are a good way to save and protect your natural tooth and can also be used to change the aesthetic appearance of your tooth. They are a good option when a larger portion of a tooth needs to be repaired or modified than other restorations such as fillings or dental bonding allow. Dr. Siemen may recommend a dental crown in the following circumstances:
- To fix a cracked tooth
- For large chips and breaks
- To cosmetically enhance your tooth
- To repair fillings or other old dental work that has broken or worn down
- As a replacement tooth on top of a dental implant
How a dental crown is placed
Depending on your needs and preferences, there are two ways to have a dental crown placed.
Traditional crowns are placed over the course of two visits. In the first visit, Dr. Siemen prepares your tooth for the dental crown, takes impressions, and places a temporary crown on your tooth while the permanent crown is being made. A couple of weeks later, when your crown is ready, you come back in and Dr. Siemen will place the crown on your tooth.
Same day crowns, also called CEREC® crowns, are designed, created, and placed all in the same visit using advanced 3D computer technology. After preparing your tooth and taking digital impressions, the crown is milled from a block of durable ceramic while you wait and then placed on your tooth the same day – saving you the time and hassle of multiple appointments.
