Dental crowns—commonly known as “caps”—are one of the most reliable and long-lasting treatments in restorative dentistry. A dental crown covers a damaged, broken, weak, or root-canal–treated tooth to restore its shape, strength, and natural appearance.
In this blog, we explain what dental crowns are, when you need them, their benefits, and which type of crown is best for you based on research and clinical experience.
What Is a Dental Crown (Cap)?
A dental crown is a custom-made protective cover placed over a tooth.
It restores:
Shape
Size
Strength
Function
Aesthetics
Crowns look and feel just like natural teeth and protect weak teeth from breaking.
When Do You Need a Dental Crown?
1. After a Root Canal Treatment
Research shows a tooth becomes up to 40% weaker after RCT.
A crown is necessary to prevent fracture and ensure long-term survival.
2. Broken, Cracked, or Fractured Tooth
If the tooth is partially broken or cracked, a crown restores stability and function.
3. Large Filling or Severe Decay
When decay is too large for a filling, a crown provides full coverage and protection.
4. Cosmetic Improvement
Crowns improve:
Tooth color
Shape
Alignment
Smile aesthetics
Perfect for smile makeover cases.
5. Dental Implants
An implant is completed only after placing a crown on top—making it function like a real tooth.
Benefits of Dental Crowns
Dental crowns offer several long-term advantages:
Protect weak or damaged teeth
Improve chewing and bite

Long-lasting solution (10+ years)

3. E-Max / Full Ceramic Crown

Zirconia: 10–20 years
