If you’ve ever had a damaged, weak, or decayed tooth, your dentist may have recommended a dental crown. These tooth-shaped caps serve as protective covers, restoring structure and function while improving appearance. But what exactly is a dental crown, and when might you need one? Read on to learn more.
What are the basics?
A dental crown fits over your tooth like a snug hat, covering everything above the gumline. Dentists use them to strengthen compromised teeth, restore worn or broken ones, and protect those treated with root canals. Crowns are also used to anchor bridges or cover dental implants.
Before placing a crown, your dentist will need to remove a small portion of your natural enamel. This step ensures the crown fits properly and bonds securely.
Reasons You Might Need a Crown
There are several situations where your dentist might recommend a crown. They are:
- To protect a weak tooth from breaking
- To support and cover a cracked or fractured tooth
- To restore a tooth that’s worn down or broken
- To cover a tooth with a large filling when not enough natural tooth remains
- To support a dental bridge
- To cover a dental implant
- To improve the appearance of a severely discolored or misshapen tooth
Types of Dental Crowns
Dental crowns come in various materials, each with its own pros and cons.
- Metal Crowns: Metal crowns are made from gold, nickel, or other alloys. They are extremely durable. They rarely chip or break and require minimal enamel removal. Their metallic appearance makes them better suited for back teeth.
- Porcelain-Fused-to-Metal: These crowns offer the strength of metal with the appearance of porcelain. They can match the color of nearby teeth, though the porcelain layer may chip over time, and a dark line can develop near the gums.
- All-Ceramic or Porcelain Crowns: These crowns look the most like natural teeth and are often used for front teeth. They’re a good option for people with metal allergies and offer a high level of aesthetic appeal.
- Pressed Ceramic Crowns: These feature a strong ceramic core layered with porcelain. They combine strength and a natural look but can still chip over time.
- All-Resin Crowns: While less expensive, resin crowns wear down faster and are more prone to fractures. They’re often used as temporary crowns.
- Same-Day Crowns: Made with CAD/CAM technology, these can be created and placed in a single visit. While convenient, they’re not suitable for every case.
What to Expect During the Procedure
Getting a crown typically takes two visits. During the first visit, your dentist will prepare the tooth, take impressions, and place a temporary crown. At the second visit, your permanent crown will be fitted and cemented.
Caring for Your Crown
To keep your crown in good shape:
- Brush and floss daily
- Avoid chewing hard or sticky foods
- Schedule regular checkups and cleanings
- Consider a mouth guard if you grind your teeth
How Long Do Crowns Last?
With proper care, dental crowns typically last 5 to 15 years. Some may last much longer, depending on the material and your oral habits. If you notice any damage or discomfort, see your dentist for an evaluation.
