Dental Crowns: When a Tooth Needs More Than a Filling

Sometimes a tooth is too damaged or weakened to be predictably repaired with a filling alone. A dental crown covers and protects the visible portion of the tooth, restoring its shape and function while helping preserve the remaining tooth structure.

What Is a Dental Crown?

A dental crown—sometimes called a cap—is a restoration that fits over the visible portion of a prepared tooth.

Unlike a filling, which replaces a specific area of missing or damaged tooth structure, a crown covers the tooth more extensively. This can provide additional support when a tooth has been significantly weakened.

Crowns can also be designed to restore the tooth’s shape, size, bite and appearance.

When Is a Crown Better Than a Filling?

Not every damaged tooth needs a crown. When enough healthy tooth structure remains, a filling or another more conservative restoration may be appropriate.

A crown may be considered when a tooth has:

Dr. Chin can evaluate how much healthy tooth structure remains and explain why a crown, filling or another restoration may be the better choice.

Will My Dental Crown Look Natural?

Tooth-colored dental crowns can be designed to blend with the surrounding teeth. The goal is to restore the damaged tooth without making the restoration unnecessarily noticeable.

Factors such as the location of the tooth, the way your teeth come together, the amount of remaining tooth structure and appearance can all influence which crown material is appropriate.

Dr. Chin can discuss the options for your particular tooth and explain the advantages and limitations of the materials being considered.

What Happens When I Get a Dental Crown?

The tooth is first carefully evaluated to determine whether a crown is appropriate. If treatment proceeds, the tooth is prepared so the restoration can fit securely over it.

Decay and weakened tooth structure are addressed as needed, and the tooth is shaped to create room for the crown.

An impression or digital record of the prepared tooth may then be used to create a crown designed for your mouth. Depending on the type of restoration and how it is made, a temporary crown may be used while the final crown is being completed.

When the final crown is ready, Dr. Chin checks its fit, appearance and how it contacts the opposing teeth before the restoration is completed.

Does Getting a Crown Hurt?

Local anesthetic is commonly used while a tooth is being prepared for a crown so the area can be treated comfortably.

Some temporary sensitivity or tenderness may occur after treatment. Your dental team will explain what to expect and how to care for the tooth afterward.

How Long Does a Dental Crown Last?

Dental crowns are designed to be durable, but no dental restoration should be considered permanent.

How long a crown lasts can depend on several factors, including your bite, oral hygiene, the condition of the underlying tooth, grinding or clenching habits, diet and the forces placed on the restoration.

Regular dental examinations allow Dr. Chin to monitor the crown, the tooth beneath it and the surrounding gums over time.

Can a Tooth Still Get a Cavity Under a Crown?

Yes. The crown itself cannot develop a cavity, but the natural tooth structure remains underneath it.

Decay can develop near the edge of a crown if plaque accumulates around the area. That’s why brushing, cleaning between the teeth and maintaining regular dental visits remain important even after a tooth has been crowned.

What If My Crown Feels Loose or Comes Off?

Call the dental office if a crown becomes loose, breaks or comes off. Avoid trying to permanently reattach it yourself.

Dr. Chin can evaluate the crown and the tooth underneath it to determine whether the restoration can be recemented, repaired or needs to be replaced.
