Filling vs. Crown: Which Does Your Cavity Need?

Wondering why some cavities can be fixed with a dental filling while others need a dental crown?

In this video, Dr. John Ku of W Plus Dental in Washington, DC uses real patient photos to explain the difference between a filling and a crown, how dentists determine which treatment is appropriate, and why the amount of healthy tooth structure remaining matters.

A dental filling is typically used when tooth decay is small to moderate and there is still enough strong, healthy tooth structure to support the tooth. The decayed portion is removed and replaced with a tooth-colored filling to restore the shape and function of the tooth.

When a cavity becomes larger or weakens a significant portion of the tooth, a filling may no longer provide enough strength or protection. In these situations, a dental crown may be recommended. A crown covers and protects more of the tooth, helping restore its strength, function, and appearance while reducing the risk of the weakened tooth breaking.

In this video, Dr. Ku explains:

• When a cavity can usually be treated with a filling

• When a cavity may require a dental crown

• The difference between dental fillings and crowns

• How the size and location of tooth decay affect treatment

• Why waiting to treat a cavity can lead to more extensive dental work

• How dentists evaluate how much healthy tooth structure remains

• What patients can expect from cavity treatment

One important takeaway: not every cavity needs a crown, but not every cavity can safely be restored with a filling. The best treatment depends on the extent of the decay, the strength of the remaining tooth, the location of the cavity, and your individual dental needs.
