What does a dental crown look like – Types and Benefits

Discover the essentials of  dental crowns, including their function and what a tooth crown looks like. Get informed about this key dental treatment.

Dental crowns are a common solution for restoring damaged teeth. They serve both functional and aesthetic purposes, protecting teeth while improving their appearance. Here’s what you need to know about dental crowns and their appearance.

What is a Dental Crown?

Think of a dental crown as a custom-fitted cap or “helmet” placed entirely over a damaged tooth. It bonds right to your existing tooth structure to instantly restore its normal shape, size, strength, and appearance.

Why Dentists Use Them

Crowns do the heavy lifting for both structural repairs and cosmetic upgrades. You might need one to:

• • Protect weak teeth: Keeps a cracked or fragile tooth from breaking apart.

  • Restore damage: Rebuilds teeth that are already broken or severely worn down.

  • Support large fillings: Strengthens a tooth when there isn’t enough natural tooth left to hold a standard filling.

  • Anchor a bridge: Serves as the secure “end-caps” that hold a dental bridge in place.

  • Mask flaws: Covers up severely discolored or misshapen teeth.

  • Finish an implant: Acts as the visible, functioning tooth placed over a dental implant post.

Types of Dental Crowns

Dental crowns are a versatile solution for restoring and protecting damaged teeth. The choice of material affects the crown’s appearance, durability, and cost. Here’s a breakdown of the types of dental crowns available and their benefits.

1. Porcelain or Ceramic Crowns

• The Look: Highly aesthetic; matches the natural color and texture of your surrounding teeth.

• The Pros: Completely metal-free (ideal for allergies) and beautiful, making them the gold standard for front teeth.

• The Cons: Less durable than metal, making them more prone to chipping under heavy biting pressure on your back molars.

2. Gold Alloys

Appearance: Distinctive gold color, noticeable compared to natural teeth.

Benefits: Highly durable and wear-resistant. They do not fracture or wear the teeth opposite them.

Considerations: The color makes them a less popular choice for visible teeth.

3. Base Metal Alloys

• The Look: Metallic (distinct gold or silver/chrome color).

• The Pros: Virtually indestructible. They do not chip, require the least amount of healthy tooth structure to be removed for fitting, and are highly gentle on opposing teeth.

• The Cons: The metallic color makes them highly noticeable, so they are typically reserved for hidden back molars.

4. Porcelain Fused to Metal (PFM)

• The Look: A hybrid option featuring a metal core with a porcelain exterior matched to your tooth color.

• The Pros: Stronger than pure porcelain and much more natural-looking than solid metal.

• The Cons: The porcelain outer layer can chip, and the metal base can sometimes show through as a dark line right at your gumline.

5. Zirconia Crowns

• The Look: Translucent white; closely mimics natural tooth enamel.

• The Pros: The ultimate powerhouse. It combines the strength of metal with the looks of porcelain. Often, these can be made in-office in a single visit using digital CAD/CAM technology.

• The Cons: Because zirconia is so incredibly hard, it can slightly wear down the natural teeth biting against it over time.

6. E-Max (Lithium Disilicate)

• The Look: Exceptional, glass-like appearance that looks almost identical to natural enamel.

• The Pros: Highly durable and structurally strong enough for both front and back teeth.

• The Cons: Comes with a premium price tag due to the advanced technology and material costs.

What Does a Tooth Crown Look Like?

The material you choose directly impacts how seamless your smile will look. Here is how the top options compare visually:

• Porcelain & Ceramic: These provide the most realistic look. They perfectly mimic the natural color and slight translucency of real tooth enamel, allowing them to blend in completely unnoticed.

• Porcelain Fused to Metal (PFM): A hybrid option that gives you a natural porcelain exterior backed by a strong metal core. The main drawback is that the dark metal base can sometimes peek through as a thin line right at the gumline.

• Gold & Base Metals: These have a distinct silver or gold metallic finish. Because they stand out sharply against your natural teeth, they are usually reserved for hidden back molars where durability matters more than looks.

Dental Crowns Before and After

Dental crowns play a crucial role in dental restoration, offering both functional benefits and aesthetic improvements. 

Before Dental Crowns

Patients might seek dental crowns for various reasons, including:

• Damaged Teeth: Cracked, chipped, or broken teeth due to accidents or wear and tear.
• Decay: Large cavities that compromise the tooth structure.
• Worn Down Teeth: Teeth worn from grinding or other causes.
• Cosmetic Improvement: Misshapen, uneven, or severely discolored teeth.
• After Root Canal Treatment: Teeth that have undergone root canal treatment and need protection.

After Dental Crowns

After the dental crown procedure, patients can expect:

• Restored Strength: Crowns encase the entire visible portion of a tooth, providing it with stability and protecting it from further damage.
• Improved Appearance: Crowns are custom-made to match the color, shape, and size of natural teeth, enhancing the smile’s appearance.
• Enhanced Functionality: With the damaged tooth structure covered, patients can enjoy a restored bite and chewing ability.
• Durability: Depending on the material, crowns can last from 5 to 15 years or longer, with proper care.
• Protection: Crowns safeguard against further decay, tooth breakage, and protect after root canal therapy.

Dental Crowns Vs Caps

Dental Crowns and Caps: Is There a Difference?

“Dental crowns” and “caps” are two terms used interchangeably to describe the same dental procedure.

Dental Crowns: This term emphasizes the restorative aspect, highlighting its role in “crowning” or completely covering the tooth.

Caps: A more colloquial term, it visually describes how the crown fits over the tooth, similar to how a cap fits over your head.

The Process of Getting a Crown

Getting a dental crown usually requires two visits to the dentist:

1. First Visit: The dentist prepares the tooth by reshaping it and takes impressions to create the crown. A temporary crown might be placed.
2. Second Visit: The temporary crown is removed, and the permanent crown is adjusted as needed and cemented into place.
