What is a Dental Crown?

A dental crown is a tooth-shaped cap placed over a damaged tooth to restore its strength, shape, and appearance. Crowns are used to protect weak teeth, restore broken teeth, and cover discolored or misshapen teeth.

Crowns fit over the entire tooth, like a snug hat. To ensure a proper fit, the dentist removes a small amount of enamel before placing the crown. Dental technicians craft crowns from materials like resin, metal, and porcelain to match the patient’s natural teeth.

When Would You Need a Dental Crown?

Crowns serve multiple purposes and are essential in various dental treatments, such as:

  • Strengthening a weak tooth
  • Protecting and supporting a cracked tooth
  • Restoring a worn-down or broken tooth
  • Holding a dental bridge in place
  • Covering severely stained or discolored teeth
  • Covering a root canal-treated tooth
  • Covering a dental implant

Types of Dental Crowns

There are several types of dental crowns, each with unique benefits and considerations:

Metal Crowns

Metal crowns are made from alloys containing gold, palladium, nickel, or chromium. These crowns are durable and resistant to chipping and breaking. They require minimal enamel removal and can withstand strong biting and chewing forces. The metallic color makes them ideal for out-of-sight molars.

Porcelain-Fused-to-Metal (PFM) Crowns

PFM crowns combine metal’s strength with porcelain’s natural look. These crowns can be matched to the color of natural teeth but may chip over time, exposing the metal underneath. They are suitable for restoring both front and back teeth.

Pressed Ceramic Crowns

Pressed ceramic crowns have a ceramic core and multiple layers of porcelain. They mimic the translucency of natural enamel and are used for both front and back teeth. However, the layers of ceramic can chip over time.

All-Ceramic or Porcelain Crowns

All-ceramic crowns are highly aesthetic and mimic the appearance of natural teeth. They are suitable for patients with metal allergies and are made from materials like zirconium dioxide. These crowns are durable and gentle on opposing teeth.

Same-Day Dental Crowns

Using CAD/CAM technology, dentists can create same-day crowns in their offices. This technology allows for digital impressions and milling of a custom crown during a single visit. While convenient, same-day crowns may not be suitable for everyone.

All-Resin Crowns

All-resin crowns are more affordable but less durable than other types. They are often used as temporary crowns and typically last three to five years.

Procedure Details

What Happens During a Dental Crown Procedure?

A dental crown procedure usually requires two appointments:

First Visit:

  1. Preparing your tooth: The dentist removes some enamel to make space for the crown and may build up the tooth with filling material.
  2. Taking impressions: The dentist takes physical or digital impressions to create the custom crown.
  3. Placing a temporary crown: A temporary crown protects the tooth while the permanent crown is made.

Second Visit:

  1. Removing the temporary crown.
  2. Checking the shape, color, and fit of the new crown.
  3. Bonding the new crown to the tooth with dental cement.

Risks and Benefits

Benefits of Dental Crowns

  • Prolong the life of natural teeth
  • Treat worn, broken, or decayed teeth
  • Protect teeth from erosion
  • Improve chewing function
  • Enhance appearance
  • Last between five and 15 years with proper care

Disadvantages of Dental Crowns

  • Require removal of some natural enamel
  • May cause sensitivity
  • Can break or fracture over time
  • Can trap bacteria if not fitted properly
  • May cause allergic reactions (rare)
  • Can be expensive

Recovery and Outlook

How Long Does it Take to Feel Better After a Dental Crown Procedure?

Most people can resume normal activities immediately after crown placement. Sensitivity to heat and cold and soreness in the gums are common for a few days. Over-the-counter pain relievers can help ease discomfort.

Foods to Avoid with a Crown

Avoid hard or sticky foods like ice, hard nuts, popcorn kernels, taffy, and caramels to prevent damage to the crown.

Are Dental Crowns Permanent?

Dental crowns can last up to 30 years with proper care but may need replacement if damaged.

How Do I Care for My Dental Crown?

  • Brush twice a day with fluoride toothpaste
  • Floss daily
  • Use antibacterial mouthwash
  • Avoid hard, crunchy, or chewy foods
  • Wear a custom mouth guard if you grind your teeth
  • Get regular dental cleanings and exams

When to Call the Dentist

Contact your dentist if you experience:

  • A loose crown
  • Bad breath or a bad taste
  • Cracks or chips in the crown
  • Sharp edges that bother your tongue or gums

Additional Details

Are Dental Crowns Painful?

Dental crowns should not be painful. Some sensitivity is normal after placement, but persistent pain should be addressed by your dentist.

Veneers vs. Crowns: Which Option is Right for Me?

  • Veneers cover the front surface of the tooth and are cosmetic.
  • Crowns cover the entire tooth and are restorative.

Alternatives to a Crown

  • Inlays and onlays: Restore teeth too damaged for fillings but too healthy for crowns.
  • Veneers: Address cosmetic concerns without decay or damage.
  • Tooth extraction and dental implant: For severely decayed or broken teeth.
