Tooth Crown (Cap): Types, Procedure, and Which One Is Best?

Banner

A tooth crown, commonly called a cap, is a custom-made covering placed over a damaged, weak, or treated tooth. It restores the tooth’s shape, strength, appearance, and function. Crowns are an essential part of modern dentistry and are widely used after root canal treatment, for cracked teeth, for cosmetic correction, and to replace missing teeth with implants.

In this blog, we break down what a crown is, types of crowns, metal vs metal-ceramic vs all-ceramic caps, and how to choose the best one for your case.

What is a Tooth Crown (Cap)?

A tooth crown is an artificial restoration that completely covers the visible part of a tooth. It acts like a helmet that protects the remaining tooth structure.

When is a crown needed?

You may need a crown when:

  • The tooth is weak or cracked
  • After root canal treatment
  • You have a large filling that cannot support chewing forces
  • To improve the shape or color of the tooth (cosmetic purpose)
  • To restore a tooth over a dental implant
  • To support a dental bridge

Crowns help restore chewing efficiency, prevent fractures, and improve smile aesthetics.

Types of Tooth Crowns

There are three major categories you can explain to patients:

1. Metal Crowns

These are made of stainless steel, nickel-chromium, cobalt-chromium, or sometimes gold alloys.

Advantages
  • Very strong and durable
  • Long lifespan
  • Less amount of tooth cutting required
  • Ideal for back teeth that receive heavy chewing force
Disadvantages
  • Poor aesthetics (metallic appearance)
  • Not preferred in visible areas
  • Some patients may have metal allergies (rare)
Best For

Back molars, patients with heavy grinding habits, or those wanting a budget-friendly option.

2. Metal-Ceramic (PFM – Porcelain Fused to Metal) Crowns

These crowns have a metal base inside and a tooth-colored ceramic layer outside. They combine strength with good looks.

Advantages
  • Strong foundation from metal
  • Natural appearance due to ceramic coating
  • Long-term durability
  • Widely used and cost-effective
Disadvantages
  • Ceramic may chip over time
  • A grey line may appear near the gum after a few years
  • Requires slightly more tooth reduction than all-ceramic crowns
Best For

Front and back teeth, patients wanting strength + good aesthetics.

3. All-Ceramic / All-Porcelain Crowns

These are made entirely of ceramic with no metal inside. New-age materials like Zirconia and E.max (lithium disilicate) offer exceptional beauty and strength.

Advantages
  • Best and most natural aesthetics
  • No metal, so no black line at the gums
  • Biocompatible (very gum-friendly)
  • Highly suitable for smile makeovers
  • Strong (especially Zirconia)
Disadvantages
  • Can be more expensive
  • Very thin margins require high-precision lab work
Best For

Front teeth, smile makeovers, and patients demanding top-level aesthetics.
