A dental crown is one of the most versatile and commonly placed restorations in dentistry. If your dentist has recommended a crown, you may be wondering what exactly it is, why you need it, and what the procedure involves. This guide answers all of your questions.
What Is a Dental Crown?
A dental crown — sometimes called a "cap" — is a tooth-shaped covering that is placed over a damaged, decayed, or weakened tooth to restore its shape, size, strength, and appearance. Once cemented in place, the crown fully encases the visible portion of the tooth above the gum line.
When Is a Crown Necessary?
Your dentist may recommend a crown in the following situations:
- A tooth has a large cavity that is too big for a filling
- A tooth is cracked, fractured, or broken
- A tooth has been weakened by decay or a large old filling
- A tooth has had a root canal treatment (to protect the treated tooth)
- A tooth is severely worn down from grinding (bruxism)
- To cover a dental implant
- To anchor a dental bridge
- For cosmetic improvement of a severely discolored or misshapen tooth
Types of Dental Crowns
Crowns are made from several different materials, each with advantages and disadvantages. Porcelain crowns (all-ceramic) are the most natural-looking and are ideal for front teeth. Porcelain-fused-to-metal (PFM) crowns offer strength and aesthetics. Zirconia crowns are extremely strong and tooth-colored, making them popular for back teeth. Gold alloy crowns are highly durable and gentle on opposing teeth, though less aesthetic. At Churchville Dental Care, we typically recommend tooth-colored porcelain or zirconia crowns for the best combination of aesthetics and durability.
The Crown Procedure: Step by Step
Getting a dental crown typically requires two appointments. At the first appointment, your dentist will numb the area, reshape the tooth to make room for the crown, take impressions (or digital scans) of your teeth, and place a temporary crown. At the second appointment (usually 2–3 weeks later), the temporary crown is removed, and the permanent crown is checked for fit, color, and bite before being permanently cemented.
How Long Do Crowns Last?
With proper care, dental crowns typically last 10–15 years or longer. Good oral hygiene — brushing twice daily, flossing, and attending regular check-ups — is the most important factor in crown longevity. Avoid chewing ice, hard candy, or using your teeth as tools, as these habits can crack or dislodge crowns.
Frequently Asked Questions
Does getting a dental crown hurt?
The crown procedure is performed under local anesthesia, so you should feel no pain during the appointment. Some sensitivity is normal for a few days after the procedure.
How much does a dental crown cost?
Dental crowns typically cost $1,000–$1,800 per tooth without insurance. Most PPO dental plans cover 50% of crown costs after your deductible is met.
Can a crowned tooth get a cavity?
Yes. While the crown itself cannot decay, the tooth underneath can still get a cavity at the margin where the crown meets the tooth. Good oral hygiene and regular check-ups are essential.
How do I care for my dental crown?
Brush twice daily with a soft-bristled toothbrush, floss daily (use a floss threader or water flosser if needed), and visit Churchville Dental Care every 6 months for check-ups.
