Summary
Dental crowns are custom-made caps that cover a damaged tooth to restore its shape, size, strength, and appearance. Available in porcelain, metal, and resin materials to suit different needs.
A dental crown is a custom-made "cap" that fits over a tooth to restore its functionality and protect it from further damage. The crown covers the entire visible portion of the tooth above the gum line.

Crown Material Comparison
| Material | Aesthetic | Strength | Durability | Best For |
|---|---|---|---|---|
| Porcelain | Excellent | Moderate | Moderate | Front teeth, cosmetic restoration |

Porcelain Crowns
- Excellent aesthetic appearance due to natural-looking color and translucency.
- Ideal for front teeth because they mimic natural enamel.
- Less likely to cause allergic reactions.
- Less durable than metal crowns — more susceptible to chipping.
Metal Crowns
- Extremely durable — can withstand significant biting and chewing forces.
- Less wear on opposing teeth.
- Require minimal removal of tooth structure.
- Highly noticeable, especially in the front of the mouth.
Resin Crowns
- More affordable than porcelain or metal crowns.
- Can be color-matched to blend with surrounding natural teeth.
- Less durable — may wear down or fracture more easily over time.
- More prone to staining compared to porcelain.
How Are Crowns Placed?
- 1Initial Visit: The dentist examines the tooth, takes X-rays, and reshapes the tooth. An impression is taken. A temporary crown is placed.
- 2Final Visit: Once your custom crown is fabricated, the dentist fits it and adjusts as needed. The crown is cemented onto the tooth.
With proper care, dental crowns can last for many years, often 10 to 15 years or more. Brush, floss, and avoid biting on hard objects to maximize your crown's lifespan.
