What Are Dental Crowns? When You Need One and What to Expect

What Is a Dental Crown?

A dental crown is a custom-made cap that covers a damaged or weakened tooth to restore its shape, strength, and appearance. It acts like a helmet, protecting the tooth underneath while blending in with your natural smile.

When Do You Need a Dental Crown?

Dental crowns are used for both restorative and cosmetic purposes. Your dentist may recommend a crown if you:

  • Have a cracked, broken, or worn-down tooth

  • Need to cover a large filling where little natural tooth remains

  • Have had a root canal treatment

  • Want to improve the appearance of a misshapen or discoloured tooth

  • Are protecting a dental implant or securing a dental bridge

Types of Dental Crowns

There are several types of crowns, and the right one depends on your needs:

  1. Porcelain or Ceramic Crowns

    • Best for front teeth

    • Natural appearance

    • Metal-free

  2. Porcelain Fused to Metal (PFM)

    • Strong and durable

    • Better for back teeth

  3. Gold or Metal Alloy Crowns

    • Extremely durable

    • Long-lasting for molars

  4. Zirconia Crowns

    • Strong and aesthetic

    • Great for people with metal allergies

What to Expect During the Procedure

Getting a dental crown usually takes two visits:

Visit 1: Tooth Preparation

  • Tooth is reshaped and cleaned

  • Impressions are taken

  • A temporary crown is placed

Visit 2: Crown Placement

  • The final crown is fitted, adjusted, and cemented into place

Tip: Some clinics offer same-day crowns using digital scanning and in-house milling technology.

How Long Do Crowns Last?

With proper care, dental crowns can last 10 to 15 years or even longer. To extend their life:

  • Practice good oral hygiene

  • Avoid hard or sticky foods

  • Visit your dentist regularly
