What are the types of dental crowns and which is best?

When a tooth becomes weak, cracked, or severely decayed, a dental crown offers an effective and durable solution to restore its strength and appearance. Crowns not only protect the remaining tooth structure but also improve your smile’s function and aesthetics.

At Banu Multispeciality Dental Clinic, Kumbakonam, we provide a wide range of advanced dental crowns made from high-quality materials to suit every patient’s dental needs and cosmetic goals. Understanding the different types of crowns can help you make an informed decision about which one is best for you.

What are the types of dental crowns and which is best?

What Is a Dental Crown?

A dental crown is a custom-made cap that covers the visible portion of a tooth. It is designed to:

• Restore the tooth’s shape, size, and strength
• Protect it from further damage or fracture
• Improve its overall appearance and alignment

Crowns are often used after root canal treatment, large fillings, or dental implant placements. They can also be part of a dental bridge to replace missing teeth.

Every crown is fabricated to fit precisely over your prepared tooth, blending seamlessly with your natural teeth.

When Do You Need a Dental Crown?

A dentist may recommend a dental crown if you have:

• A tooth with extensive decay or a large filling
• A cracked, fractured, or weakened tooth
• Severe enamel wear or discoloration
• A tooth after root canal therapy
• A dental implant requiring coverage
• A misshapen or cosmetically imperfect tooth

At Banu Multispeciality Dental Clinic, Kumbakonam, our dental experts assess your oral health and bite pattern before suggesting the most suitable type of crown for long-term durability and comfort.

Types of Dental Crowns

Modern dentistry offers a variety of crown materials, each with its own set of strengths, aesthetics, and ideal applications. Let’s explore the most common types.

1. Porcelain-Fused-to-Metal (PFM) Crowns

PFM crowns combine the strength of a metal base with the natural appearance of porcelain. The inner metal layer provides durability, while the outer porcelain layer mimics tooth color.

Advantages:

• Strong and long-lasting
• Suitable for both front and back teeth
• Natural-looking appearance

Considerations:

• May show a thin metal line at the gumline over time
• Porcelain layer can chip if subjected to excessive pressure

Best for:
Patients seeking a balance between strength and aesthetics.

2. All-Ceramic (Porcelain) Crowns

These crowns are made entirely of ceramic or porcelain, offering superior aesthetics that closely match natural enamel. They are a popular choice for front teeth restorations.

Advantages:

• Excellent color matching
• Metal-free and biocompatible
• Ideal for patients with metal allergies

Considerations:

• Slightly less durable than metal-based crowns for molars
• Can wear down opposing teeth if not polished correctly

Best for:
Front teeth restorations and patients prioritizing cosmetic results.

3. Zirconia Crowns

Zirconia is a high-strength ceramic material known for its exceptional durability and lifelike translucency. It is one of the most popular modern options for both anterior and posterior crowns.

Advantages:

• Extremely strong and fracture-resistant
• Excellent aesthetics
• Long-lasting with proper care
• Requires less tooth preparation

Considerations:

• More expensive than traditional PFM crowns
• Can be difficult to adjust once placed

Best for:
Patients who want the most durable and aesthetic metal-free crown for any tooth.

4. E-Max (Lithium Disilicate) Crowns

E-Max crowns are made from a single block of lithium disilicate ceramic — known for strength and translucency. They are thinner than traditional crowns yet remarkably strong.

Advantages:

• Highly aesthetic and lifelike appearance
• Lightweight yet durable
• Requires minimal tooth reduction
• Metal-free and biocompatible

Considerations:

• More suitable for front and premolar teeth than molars
• Higher cost due to advanced technology

Best for:
Smile makeovers and visible front teeth requiring top-tier aesthetics.

5. Metal Crowns (Gold or Base Metal Alloys)

Metal crowns have been used in dentistry for decades due to their unmatched durability. Although not as aesthetic, they remain one of the most functional choices for molars.

Advantages:

• Exceptional strength and wear resistance
• Minimal tooth reduction required
• Rarely chip or break

Considerations:

• Metallic color makes them less suitable for visible teeth
• Not ideal for patients seeking natural aesthetics

Best for:
Back teeth and patients who prioritize strength over appearance.

6. Stainless Steel Crowns (Pediatric Use)

Stainless steel crowns are prefabricated metal caps commonly used for children’s primary teeth. They protect baby teeth until they naturally fall out.

Advantages:

• Quick placement and durable protection
• Cost-effective solution for kids
• Prevents decay progression and maintains spacing

Best for:
Temporary crowns for primary (baby) teeth in pediatric dentistry.

Comparing Different Crown Materials

Which Type of Crown Is Best?

The best dental crown depends on your specific dental needs, budget, and cosmetic preferences.

Here’s how to decide:

• For strength and long-term durability: Zirconia crowns are an excellent choice.
• For superior aesthetics: E-Max or all-ceramic crowns provide the most natural look.
• For balanced performance: Porcelain-fused-to-metal crowns offer durability with decent aesthetics.
• For back teeth: Metal crowns withstand heavy chewing forces best.
• For children: Stainless steel crowns protect developing teeth until permanent ones erupt.

At Banu Multispeciality Dental Clinic, Kumbakonam, our dentists help you choose the perfect crown based on your oral condition, bite alignment, and smile goals.

How Dental Crowns Are Placed

The crown placement procedure typically involves two visits:

1. First Visit – Tooth Preparation and Impression:
   The tooth is reshaped, impressions are taken, and a temporary crown is placed.
2. Second Visit – Permanent Crown Placement:
   The custom-made crown is fitted, adjusted, and permanently bonded for a precise and comfortable result.

With advanced technology and digital imaging at Banu Dental, the entire process is accurate, efficient, and designed for long-term comfort.

Caring for Your Dental Crown

To ensure longevity and maintain your crown’s beauty:

• Brush and floss daily using a soft-bristled toothbrush.
• Avoid biting hard objects or using teeth as tools.
• Visit your dentist every six months for checkups and polishing.
• Limit coffee, tea, or smoking to prevent discoloration around the crown margins.

With proper care, crowns can last 10–20 years or more, depending on the material and oral hygiene.
