What is Build-Up for a Dental Crown? A Comprehensive Guide
Getting a dental crown is a common procedure to restore a damaged or decayed tooth. But before the crown itself is cemented in place, a crucial step often occurs: the build-up. This process prepares the tooth for the crown, ensuring a proper fit and long-lasting result. Let's delve into what build-up is, why it's needed, and what to expect.
What exactly is a dental build-up?
A dental build-up is the process of adding material to a tooth that's been significantly damaged or worn down before a crown is placed. This "build-up" essentially reconstructs the tooth to the correct shape and size, providing a solid foundation for the crown. Without it, the crown might not fit properly, leading to potential issues like discomfort, poor aesthetics, or even crown failure.
Why is a dental build-up necessary?
Several reasons necessitate a build-up before crown placement:
-
Extensive Tooth Decay or Fracture: If a large portion of the tooth is missing due to decay or a fracture, there won't be enough remaining structure to support a crown adequately. The build-up adds the necessary bulk to provide this support.
-
Insufficient Tooth Height: A tooth that's too short might not provide sufficient retention for the crown. A build-up increases the tooth's height, creating a more secure fit.
-
Improper Tooth Shape: If the tooth is irregularly shaped or has uneven surfaces, a build-up can restore a natural form, ensuring a better-fitting and more aesthetically pleasing crown.
-
Root Canal Treatment: Teeth that have undergone root canal therapy often require a build-up because the procedure can weaken the tooth structure.
What materials are used for a build-up?
Several materials can be used for dental build-ups, each with its own advantages and disadvantages:
-
Composite Resin: A tooth-colored material that's relatively inexpensive and easy to apply. It's a good option for smaller build-ups.
-
Amalgam: A silver-colored filling material that’s strong and durable but not aesthetically pleasing. It’s typically used for more extensive build-ups in less visible areas.
-
Gold Inlays or Onlays: These are custom-made restorations that can provide excellent strength and durability for more significant build-ups. They're usually used when a large portion of the tooth needs to be restored.
-
Ceramic: A tooth-colored material that provides strength and excellent aesthetics. It's suitable for both smaller and larger build-ups.
What is the procedure like?
The process of a dental build-up usually involves:
-
Preparation: The dentist will clean and prepare the tooth surface. Any remaining decay will be removed.
-
Build-up Placement: The chosen material is carefully applied and sculpted to restore the tooth's shape and size. This often requires multiple appointments to ensure accuracy and proper curing of the material.
-
Shaping and Polishing: Once the build-up is complete, it's shaped and polished to achieve a smooth, natural-looking finish.
-
Crown Placement: After the build-up is fully cured and the dentist is satisfied with the fit, the crown can then be prepared and cemented.
How long does a build-up last?
The longevity of a build-up depends on several factors, including the material used, the extent of the build-up, and the patient's oral hygiene habits. With proper care, a well-placed build-up can last for many years.
Does a build-up hurt?
The procedure is generally comfortable due to the use of local anesthesia. Some patients might experience mild sensitivity afterward, but this usually subsides quickly.
Are there alternatives to a build-up?
In some cases, alternatives might exist, depending on the extent of the damage. These could include a larger restoration or even extraction and implantation. However, a build-up remains a preferred option when enough healthy tooth structure remains to support it.
