What is the Purpose of a Dental Crown?
- Protects a decaying tooth from breaking or keeps a cracked tooth together
- Covers a tooth with a large filling when there isn’t much tooth left
- Holds a dental bridge in place
- Covers a dental implant
- Covers discolored teeth
- Restores a broken down or worn tooth
In the past, a crown or cap, took two appointments to complete. Those steps are listed below. Our office offers the ability to have your crown done in one slightly longer appointment. Your tooth with be prepared by the dentist and then scanned. While you wait, your crown will be milled in our office and the fit can be checked right away. Following a hardening process, the final restoration is placed. No second appointment, no temporary crown, no need to be numb a second time.
The First Crown Appointment
If you are not a candidate for a Cerec crown the process of making the crown begins by the dentist numbing the patient’s tooth as well as the gum tissue that surrounds it. After this, a certain amount of the tooth may need to be trimmed for shaping purposes. This shaping process is to ensure that once the permanent crown is put in place, the tooth won’t be oversized. During this shaping process, any additional decay must also be removed from the tooth along with any loose portions of the tooth.
Once the tooth has been shaped properly, the dentist will need to take an impression of the tooth. To take the impression, the dentist will use a paste or putty-like compound that is most often called “impression material.”
During the time that the patient waits for their permanent crown to be made, the dentist will place a temporary crown on the tooth, which is typically made of a thin shell of metal or plastic and is cemented using “temporary” cement so that it can be removed easily during the patient’s next visit.
The Second Crown Appointment
After the permanent crown has been created, the patient will have the crown cemented in place by the dentist. Before the dentist permanently cements the crown in place, they must make sure that it looks right and fits well. To do this, the dentist will place the crown in the patient’s mouth, see how it fits, and make adjustments as needed. Once the dentist is satisfied, they may ask the patient how they feel about the look and color of the crown. If both parties are happy, the new crown will be permanently cemented in place.
Types of Crowns
Metal – Crowns with metal as their base include gold alloy, a base-metal alloy such as chromium or nickel, or another type of alloy such as palladium. With this type of crown, less tooth structure needs to be removed and less tooth wear is caused to opposing teeth. Metal crowns are also typically known as being one of the longest lasting types of crowns and can withstand high biting and chewing forces. The main drawbacks with these is their color and potential for allergic reaction.
Porcelain-fused-to-metal – These crown types can be matched by color to a patient’s tooth. However, wearing can occur because the crown’s porcelain portion can break off or chip. This type of crown is good for both front and back teeth.
All-Ceramic or All-Porcelain – These crown types are known to be the best match color-wise for teeth compared to other crowns. They are also very much suitable for anyone with a metal allergy. In most cases, your crown can be made in one appointment with our crown system.
