Dental crowns are prescribed to protect weak teeth. When a tooth has a very large cavity, existing old restoration, or other damage that cannot simply be repaired by just a filling, a crown is needed to provide better protection. For instance, many people have unexplained pain on filled back teeth, which is usually due to small fractures in the chewing portion of the tooth. Applying a crown on these teeth relieves the pain and restores the functions of these teeth. In the front teeth, old fillings can not only weaken the teeth but also affect the esthetic appearance of these teeth. Crowns can be use to prevent breakage and prevent the teeth from further weakening and staining.
There are many materials we can use to fabricate the crown. We can use all porcelain, gold, precious metal, or a combination of them. With proper care, these restorations can last for 20 to 30 years.
How many appointments are needed?
At least two appointments are needed to fit a dental crown. During the first appointment, Dr. Chang-LeMone will remove the decay and any damaged tooth portion, then the tooth is rebuilt and shaped to create the proper form for the crown material. Then a temporary crown will be fitted onto your tooth. Two weeks later, you will return to our office for the crown seating appointment. During which time, Dr. Chang-LeMone will ensure the proper fit and function your final crown before she permanently cements it onto your tooth.
