A dental crown is a custom-made cap placed over a damaged tooth to restore its shape, strength, and function. The main types of dental crowns available include zirconia crowns, ceramic crowns, E-Max crowns, gold crowns, porcelain-fused-to-metal crowns, and resin crowns, each offering different benefits for front teeth and back teeth. According to research tracking 2,340 dental crowns, approximately 97% of crowns remain functional after 10 years with proper dental care.
What is a Dental Crown
A dental crown is a tooth-shaped restoration that covers the entire visible portion of a tooth above the gum line. The dental crown procedure involves preparing the damaged tooth, taking impressions, and cementing a permanent crown that matches the colour of your natural teeth. Crowns are designed to protect weak teeth, restore broken teeth, support dental bridges, and cover dental implants.

Your dentist may recommend getting a dental crown for various dental issues, including severe decay, fractures, or after root canal treatment. The crown made from an appropriate material can last many years with regular dental check-ups and good dental hygiene practices.
Types of Dental Crowns Explained
Understanding the various types of dental crowns helps you choose the right dental crown for your specific needs. Each crown type offers unique advantages depending on whether you need restoration for front and back teeth.
1. Zirconia Dental Crowns
Zirconia crowns are made from zirconium dioxide, a biocompatible material known for exceptional strength. These crowns are highly durable and resistant to fractures, making them suitable for both front teeth and back teeth that endure heavy chewing forces.
The zirconia dental crown price reflects its superior quality and longevity. Zirconia crowns combine strength with aesthetics, though they may not always provide the same translucency as all-ceramic crowns. Research shows that monolithic zirconia crowns demonstrate excellent resistance to high bite forces.
The dental crown material zirconia offers metal-free construction, eliminating the dark lines sometimes visible with metal crowns. Zirconium oxide dental crowns are a popular choice for patients seeking durability without compromising appearance.
2. Ceramic Dental Crowns
A ceramic dental crown provides the most natural appearance among various dental crown options. These porcelain or ceramic crowns match the translucency and colour of natural teeth better than any other crown type, making them ideal for front teeth where aesthetics matter most.
All-ceramic crowns contain no metal, preventing allergic reactions and eliminating the dark gum line that can appear with some crown types. The ceramic material blends seamlessly with surrounding teeth. However, ceramic crowns are generally less durable than zirconia crowns for back teeth that endure significant pressure.
Porcelain dental crowns and other ceramic options require precise fabrication techniques. The crown offers excellent biocompatibility and long-term colour stability when properly maintained.
3. E-Max Dental Crowns
An E-max dental crown represents advanced all-ceramic technology using lithium disilicate material. These crowns are known for superior strength compared to traditional porcelain crowns while maintaining excellent aesthetics for front and back teeth.
E-Max crowns offer remarkable translucency, closely mimicking natural tooth structure. The material used in E-Max crowns allows for thinner crown preparation, preserving more of the original tooth. These crowns are often used for patients requiring both strength and natural appearance.
The crown can last 10-15 years or longer with proper care. E-Max technology has transformed the option for dental restorations by eliminating the need for metal frameworks.
4. Gold Dental Crowns
Gold crowns have been used in dentistry for decades due to their exceptional longevity and biocompatibility. These metal crowns are highly durable, resistant to wear, and gentle on opposing teeth during chewing.
Gold crowns typically contain a gold alloy mixed with other metals for added strength. The crown type requires minimal tooth removal during preparation and forms excellent seals with dental cement, reducing the risk of decay beneath the crown.
While gold crowns lack the natural appearance of ceramic options, they remain a reliable choice for back teeth where function trumps aesthetics. The crown made from gold alloy rarely fractures and can last 20+ years with regular dental care.
5. Porcelain-Fused-to-Metal Crowns
Porcelain-fused-to-metal crowns (PFM crowns) combine metal strength with porcelain aesthetics. These crowns combine a metal substructure with a porcelain outer layer, offering durability for back teeth while providing a reasonable appearance for visible areas.
The metal framework provides structural support, while the porcelain coating mimics tooth colour. However, the metal may eventually show as a dark line near the gum line as gums recede. PFM crowns are often used when strength is prioritized but some aesthetic consideration remains important.
These crowns are also suitable for dental bridges requiring multiple connected units. The material used provides a balance between various types of crowns available on the market.
6. Resin Crowns
Resin crowns are made from composite materials and represent the most affordable temporary crown or permanent crown option. Composite resin crowns are generally less expensive than ceramic or metal alternatives but have shorter lifespans.
These crowns are a common choice for temporary restorations during the dental crown procedure while permanent crowns are fabricated. Resin crowns may stain over time and are more prone to wear and fracture compared to other types of dental crowns.
A temporary crown protects the prepared tooth and maintains spacing until the final restoration is ready. While not ideal for long-term use, resin serves a valuable purpose in dental treatment planning.
7. Stainless Steel Crowns
Stainless steel crowns are prefabricated metal crowns used primarily for children’s primary teeth or as temporary adult crowns. These crowns are highly durable, cost-effective, and can be placed quickly during a single dental visit.
For pediatric patients, stainless steel crowns protect damaged teeth until natural exfoliation occurs. In adults, they may serve as interim restorations. The crown type offers excellent protection despite lacking aesthetic appeal.

According to the Australian Institute of Health and Welfare, approximately 50% of Australians hold private dental insurance that may partially cover crown procedures. Dental insurance policies typically reimburse a percentage of the dental crown cost, depending on annual limits and waiting periods.
The actual out-of-pocket cost depends on your dental health fund coverage and whether your dentist participates in your insurer’s preferred provider network.
Which Type of Dental Crown Is Best for You?
Choosing the right dental crown depends on several factors, including tooth location, functional requirements, aesthetic preferences, and budget considerations. Your dentist will evaluate your specific dental issues during the consultation.
For front teeth, ceramic crowns, E-Max, or zirconia crowns offer the best appearance, matching natural teeth. These options provide the translucency and colour gradation necessary for a seamless smile. The benefits of dental crowns for anterior teeth include restored confidence and natural aesthetics.
For back teeth that endure heavy chewing forces, zirconia crowns or gold crowns provide superior durability. These materials resist fracture and wear better than porcelain crown alternatives. Metal crowns also work well for molars, where appearance is less critical.
Patients with metal allergies should choose all-ceramic crowns or zirconia options. Those seeking maximum longevity often select gold crowns or zirconia crowns, both of which can last decades. The crown may need replacement eventually, but quality materials extend this timeline significantly.
Consider discussing crowns and their costs with your dental provider. Getting dental crowns requires understanding not just the initial investment but the long-term value. Various dental crown types serve different purposes in comprehensive dental restoration.
“The right crown isn’t always the most expensive option; it’s the one that best matches the patient’s functional needs, aesthetic goals, and maintenance capabilities,” notes Dr James Chen, who has completed over 3,000 crown procedures.
Your dentist will take impressions or digital scans, discuss the dental crown procedure timeline, and explain temporary crown placement before your permanent crown is ready. Need a dental crown decision shouldn’t be rushed; proper evaluation ensures optimal outcomes.
According to Australian dental research, approximately 53% of Australians visited dental professionals in the past year. Regular dental check-ups help identify when crowns or other dental treatments become necessary before problems worsen.
