What Materials Are Used in Dental Crowns, and How Do They Differ in Durability and Aesthetics?

December 4, 2023

When a tooth becomes severely damaged or decayed, a cap known as a dental crown is required to restore functionality and appearance. Crowns are custom-made covers that fit over the entire visible part of a tooth. There are various materials dentists use to create these tooth caps, each with their own advantages.

What Are the Common Materials for Dental Crowns?

The most frequently used materials for dental crowns include:

  • Porcelain fused to metal – A metal structure fused to a porcelain exterior provides strength and aesthetics.
  • All-ceramic – No metal is used, only high-strength ceramic material to mimic natural tooth color. Types include zirconia and lithium disilicate.
  • Gold alloys – Gold combined with other metals like silver, copper, and platinum.
  • Metal alloys – Mixtures like nickel, chromium, and cobalt for strength and wear resistance.
  • Acrylic or resin – Plastic-based crowns are primarily used as temporary restorations.

The choice depends on factors like location in the mouth, cost, and personal preferences.

Durability Factors: How Long Do Different Crown Materials Last?

The lifespan of a dental crown in Annapolis, MD, depends on the material, oral hygiene, and chewing forces. In general:

  • Gold crowns last the longest, from 10-30 years or more. Their strength and durability is unmatched.
  • Porcelain fused to metal can last 10-15 years or longer with proper care.
  • All-ceramic zirconia crowns offer comparable longevity of 10 years or more. Their fracture resistance approaches metal alloys.
  • Acrylic and resin temporary crowns only last about six months to a year before a permanent crown is needed.

With good oral hygiene and avoiding teeth grinding, even porcelain crowns can provide a decade or more of reliable service before replacement is needed.

Aesthetics Comparison: Natural Look of Various Crown Materials

For front visible teeth, people usually want the most natural-looking dental crown material. Comparisons on aesthetics:

  • All-ceramic offers the most visual appeal and realistic translucency of natural teeth. No metal shines through.
  • Porcelain fused to metal can mimic a natural tooth shade, but the metal underlying base can create a grayish line at the gumline.
  • Full gold crowns are the most eye-catching and least natural for front teeth. The yellow-gold color is visible as the tooth color.
  • Temporary acrylic and resin crowns allow some customization of color but have a visibly artificial appearance.

When mimicking real teeth’ natural color, shape, and light transparency, all-ceramic zirconia or lithium disilicate are the most visually appealing options.

Which Crown Material Is Best for Front Teeth?

All-ceramic crowns are usually the top choice for front teeth from an aesthetic standpoint. Their life-like appearance makes them virtually indistinguishable from surrounding natural teeth. While strong, their fracture-resistance may not match gold or porcelain-fused-to-metal crowns.

For back molars, durability and wear resistance are higher priorities than aesthetics. Here, gold, porcelain-fused-to-metal, or zirconia crowns are best. Your dentist in Pomona will advise on the ideal crown material for each tooth based on location, cost, longevity, and aesthetics.

In conclusion, modern dental crown materials provide excellent durability, function, and life-like aesthetics.
