A dental crown is a tooth-shaped “cap” placed over a damaged, decayed, or weakened tooth to restore its shape, strength, and function. Crowns can also improve the appearance of a tooth and protect it from further damage.
When Are Dental Crowns Used?
Crowns are often recommended in situations such as:
- Large Filling
When a tooth has a large filling that compromises its structure, a crown can protect and strengthen it. - Severe Decay
For teeth with extensive decay that can’t be restored with a regular filling, crowns provide a stronger, longer-lasting solution. - Cracked or Worn Teeth
Crowns help protect and restore cracked, fractured, or heavily worn-down teeth. - Following a Root Canal
After a root canal, the tooth may become more brittle, so a crown is used to reinforce it. - Dental Implant Restoration
A crown is placed on top of an implant to serve as a replacement tooth. - Cosmetic Enhancement
Crowns can improve the appearance of discolored or misshapen teeth.
Types of Dental Crowns
- Metal Crowns
Made from materials like gold or alloy, these are highly durable and are usually used for molars that are out of sight. - Porcelain-Fused-to-Metal (PFM) Crowns
These combine metal’s strength with a natural tooth-colored porcelain exterior, making them both strong and aesthetic. - All-Ceramic or All-Porcelain Crowns
These provide the best natural color match, especially for front teeth, but may not be as strong as metal-based crowns. - Resin Crowns
These are more affordable but less durable than other types, often used as a temporary solution. - Zirconia Crowns
Known for their strength and natural appearance, zirconia crowns are highly durable and less likely to chip.
Benefits of Dental Crowns
Protection
Crowns shield weakened or damaged teeth from further harm.
Durability
A well-maintained crown can last 10–15 years or longer.
Natural Look
Porcelain and ceramic crowns are custom-colored to blend with your natural teeth.
Enhanced Comfort and Function
Crowns restore the full functionality of teeth, improving chewing and speaking abilities.
Caring for a Dental Crown
Dental crowns require similar care to natural teeth, including regular brushing, flossing, and dental check-ups. Avoiding hard foods and teeth grinding can also help prolong the life of a crown.
