A dental crown is a custom-made cap that covers a damaged tooth to restore its shape, strength, and size. Crowns protect teeth that have been weakened by decay, fracture, or extensive restorations, and they are commonly placed after root canal therapy to prevent the treated tooth from breaking. Crowns also cover dental implants and serve as anchors for dental bridges. This guide explains when a dentist recommends a crown, how the procedure works, what materials are available, and how long crowns last.

What Is a Dental Crown?
A dental crown is a tooth-shaped cap that covers the entire visible portion of a tooth above the gum line. The crown restores the tooth’s original size, shape, strength, and appearance, and it protects the underlying tooth structure from further damage.
Dentists also refer to crowns as dental caps. A crown differs from a filling because it covers the entire tooth rather than filling a cavity within it. Crowns are cemented into place and remain in position permanently unless they loosen or require replacement.
Dental crowns serve restorative, cosmetic, and prosthetic functions. A crown restores a fractured tooth, covers a dental implant, anchors a dental bridge, or improves the appearance of a misshapen or discolored tooth. The American Dental Association recognizes crowns as a standard treatment for teeth with extensive structural loss .
When Does a Dentist Recommend a Dental Crown?
A dentist recommends a dental crown when a tooth has lost too much structure to support a filling or when covering the tooth protects it from fracture. Crowns address several clinical situations.
- Large cavities: When decay has destroyed more than half of a tooth’s structure, a filling cannot provide sufficient support. A crown covers the remaining tooth and prevents it from cracking.
- Cracked or fractured teeth: A cracked tooth can split completely under chewing pressure. A crown holds the tooth together and protects it from further damage.
- After root canal therapy: Root canal-treated teeth become brittle because the pulp has been removed. A crown protects the tooth and restores function.
- Severely worn teeth: Teeth worn down by grinding or acid erosion may require crowns to rebuild their original height and shape.
- Dental implants: Crowns cover dental implants and provide the visible chewing surface of the replacement tooth.
- Dental bridges: Crowns on adjacent teeth anchor a dental bridge in place.
- Cosmetic improvement: Crowns can improve the appearance of severely discolored or misshapen teeth when veneers are not an option.
What Materials Are Used for Dental Crowns?
Dental crowns are made from several materials, each offering different advantages in strength, appearance, and cost. The choice depends on the tooth’s location, the patient’s aesthetic goals, and the amount of force the crown must withstand.
Porcelain fused to metal crowns combine the strength of a metal base with a tooth-colored porcelain exterior. All-ceramic crowns offer the best aesthetic match for natural teeth and are commonly used on front teeth. Zirconia crowns provide high strength and good appearance, making them suitable for both front and back teeth. Gold and base metal crowns are durable but visible, so dentists typically reserve them for back teeth.
What Happens During Dental Crown Placement?
Dental crown placement typically requires two appointments, though same-day crown technology allows some crowns to be designed, fabricated, and placed in a single visit. The procedure involves preparing the tooth, taking impressions, and cementing the finished crown.
First Appointment: Tooth Preparation
The dentist numbs the tooth and surrounding gum tissue with local anesthesia. Using a dental drill, the dentist reshapes the tooth by removing a portion of its outer surface, typically 1 to 2 millimeters, to make room for the crown. The amount of tooth reduction depends on the crown material.
After shaping the tooth, the dentist takes an impression or digital scan of the prepared tooth and the surrounding teeth. This impression is sent to a dental laboratory where a technician fabricates the custom crown. The dentist places a temporary crown to protect the prepared tooth while the permanent crown is being made.
Second Appointment: Crown Cementation
At the second appointment, usually two to three weeks later, the dentist removes the temporary crown and checks the fit, color, and shape of the permanent crown. After confirming the fit, the dentist cements the crown into place and adjusts the bite to ensure comfortable chewing. Some patients experience mild sensitivity after the procedure, which typically resolves within a few days.
Same-Day Crowns
Same-day crowns use CAD/CAM technology to design and mill a crown in the dental office. The dentist scans the prepared tooth, designs the crown on a computer, and mills it from a ceramic block while the patient waits. Same-day crowns eliminate the need for a temporary crown and a second appointment, though not all clinical situations are suitable for this approach.
How Long Do Dental Crowns Last?
Dental crowns last an average of 10 to 15 years, though many crowns remain functional for 20 years or longer with proper care. Crown longevity depends on the material, the amount of healthy tooth structure remaining, oral hygiene habits, and whether the patient grinds their teeth.
Factors that shorten crown lifespan include poor oral hygiene, gum disease, bruxism (teeth grinding), and biting hard objects such as ice or fingernails. Regular dental checkups allow the dentist to detect early signs of crown wear, loosening, or decay at the crown margin.
A crown can be replaced if it wears out, breaks, or becomes loose. Replacing a crown before it fails protects the underlying tooth from fracture and may prevent the need for more extensive treatment.
Dental Crown vs Filling: Which Is Right for Your Tooth?
A dental filling repairs a small to moderate cavity, while a dental crown covers and protects a tooth that has lost significant structure. The choice between a crown and a filling depends on how much healthy tooth remains after the dentist removes decay.
A dentist recommends a crown when the remaining tooth structure is too weak to support a filling. Fillings placed in teeth with large cavities can cause the tooth to flex and crack under chewing pressure. A crown distributes force across the entire tooth and holds it together.

Frequently Asked Questions About Dental Crowns
Does getting a dental crown hurt?
Dental crown placement does not hurt because the dentist numbs the tooth and surrounding tissue with local anesthesia. Patients may experience mild sensitivity or gum soreness for a few days after the procedure, which typically resolves on its own.
How long does it take to get a dental crown?
Traditional crown placement takes two appointments spaced two to three weeks apart. The first appointment lasts 60 to 90 minutes for tooth preparation and impressions. The second appointment takes about 30 minutes for cementation. Same-day crowns are completed in a single visit of two to three hours.
Can a dental crown be replaced?
Yes, a dental crown can be replaced if it wears out, breaks, or becomes loose. The dentist removes the old crown, examines the underlying tooth, and fabricates a new crown. If the tooth has decayed beneath the crown, the dentist treats the decay before placing the new crown.
Do dental crowns look natural?
Porcelain, ceramic, and zirconia crowns look natural because they match the color, translucency, and texture of adjacent teeth. A dentist shades the crown to blend with the patient’s natural teeth. Metal crowns do not look natural, so dentists typically use them only on back teeth where they are not visible.
Can I eat normally with a dental crown?
Patients can eat normally with a dental crown once it is cemented into place. The crown restores full chewing function. Patients should avoid biting hard objects such as ice, pens, and fingernails, which can damage the crown or the underlying tooth.
People Also Ask
What is the difference between a dental crown and a dental cap? A dental crown and a dental cap are the same thing. Cap is an informal term for a crown, which covers the entire visible portion of a tooth.
How much does a dental crown cost? Dental crown costs vary based on the material, the dentist’s location, and insurance coverage. Porcelain crowns typically cost more than metal crowns. Patients should consult their dentist and insurance provider for specific pricing.
Can a tooth with a crown still decay? Yes, a tooth with a crown can still decay, usually at the margin where the crown meets the gum line. Good oral hygiene and regular dental checkups help prevent decay around crowns.
What happens if a crown falls off? If a crown falls off, the patient should keep the crown and contact their dentist immediately. The dentist can usually re-cement the crown if it is not damaged. In the meantime, the patient should keep the area clean and avoid chewing on that side.
Are dental crowns covered by insurance? Dental insurance typically covers crowns when they are medically necessary, such as after a root canal or for a fractured tooth. Coverage usually ranges from 50% to 80% after deductible. Cosmetic crowns may not be covered.
