Your Essential Guide to the Types of Dental Crowns and Cost Breakdown

Dental crowns are a common and highly effective restorative solution for fixing damaged or decayed teeth, improving appearance, and restoring normal function. Whether you need a permanent crown for a decayed tooth or a temporary crown while waiting for a final crown, understanding the different types of dental crowns and their costs can help you make an informed decision. This guide breaks down the various types of dental crowns and cost, their benefits, and the procedure involved in Australia.

Why Might You Need a Dental Crown?

A dental crown is a covering designed to encase and protect a tooth to regain its shape, size, strength, and appearance. Dentists often recommend dental crowns for various reasons related to both function and aesthetics. Here are some common situations where you might need a dental crown:

1. To Restore a Damaged or Decayed Tooth: When a tooth is seriously damaged or decayed, and a filling is insufficient, a dental crown offers the strength and protection needed to prevent further deterioration.
2. After Root Canal Treatment: A tooth that has received root canal treatment tends to become more brittle. A crown helps protect the treated tooth, restoring its functionality and reducing the risk of fractures.
3. To Support a Tooth with a Large Filling: When a tooth has a large filling and not much natural tooth structure remains, a crown helps hold the tooth together, providing additional support and preventing cracks.
4. To Improve Aesthetic Appearance: Porcelain or ceramic crowns can enhance the appearance of discoloured, misshapen, or uneven teeth, offering a more natural and attractive look.
5. To Replace Missing Teeth with Dental Implants: A crown is often placed over a dental implant to function as an artificial tooth, restoring both the look and function of the missing tooth.
6. To Secure a Dental Bridge: Dental crowns are used to support a bridge when replacing missing teeth, offering stability and ensuring correct alignment with neighbouring teeth.
7. To Protect Worn or Cracked Teeth: Teeth that are worn down from grinding (bruxism) or those with cracks can benefit from crowns, which act as a shield to prevent further damage.
8. For Children with Severe Tooth Decay: In paediatric dentistry, stainless steel crowns are sometimes used to protect baby teeth that are too decayed for fillings, helping maintain space for the permanent teeth to come in properly.

Different Types of Dental Crowns: How to Choose the Right One for You

When it comes to restoring a damaged or decayed tooth, dental crowns are a reliable solution. They come in various materials, each offering different benefits in terms of durability, aesthetics, and cost. The right crown for you will depend on factors like the tooth’s location, your budget, and your personal preferences.

Here’s an in-depth look at the most common types of dental crowns and their starting prices in Australia.

1. Porcelain Crowns – The Natural Choice for Aesthetics

Porcelain crowns, also known as ceramic crowns, are popular for their natural appearance. They are crafted to blend seamlessly with the colour and texture of your natural teeth, making them a perfect option for front tooth restorations where appearance is essential. Porcelain crowns are biocompatible, meaning they contain no metal, which minimises the risk of allergic reactions.

Key Features:

• Best suited for visible teeth
• Excellent for achieving a natural look
• Resistant to staining

Considerations:

While they offer outstanding aesthetics, porcelain crowns can be more fragile compared to metal options, making them prone to chipping under heavy pressure, especially on back teeth.

Starting Price: $1,500

2. Porcelain-Fused-to-Metal (PFM) Crowns – The Best of Both Worlds

Porcelain-fused-to-metal (PFM) crowns offer the durability of a metal core combined with the natural aesthetics of porcelain. Featuring a strong metal foundation topped with tooth-coloured porcelain, they provide both strength and an appealing look, making them suitable for both front and back teeth.

Key Features:

• Strong and durable due to the metal core
• Aesthetic appeal similar to porcelain crowns
• Suitable for high-stress areas like molars

Considerations:

Over time, the metal underneath the porcelain can become visible as a dark line near the gums, which might affect the appearance, especially on the front teeth. The porcelain layer can also wear down or chip with heavy use.

Starting Price: $1,200

3. Zirconia Crowns – The Ultimate in Strength and Durability

Zirconia crowns are fabricated from a highly durable ceramic material known as zirconium dioxide. They are known for their exceptional strength, making them suitable for back teeth where chewing forces are the strongest. Zirconia crowns also offer a good balance between durability and aesthetics.

Key Features:

• Extremely strong and resistant to cracks or chips
• Can be colour-matched to natural teeth
• They are less prone to causing wear on opposing teeth than traditional metal crowns.

Considerations:

While zirconia is strong, it can sometimes be more abrasive to surrounding teeth if not polished correctly. Additionally, zirconia crowns are generally costlier than other types because of their exceptional durability and the sophisticated manufacturing techniques involved.

Starting Price: $1,500

4. Gold Crowns – The Long-Lasting Traditional Option

Gold crowns have been used in dentistry for decades due to their exceptional durability and biocompatibility. They are made from a gold alloy, which can also include other metals like copper or palladium for added strength. Although not as aesthetically pleasing as porcelain or zirconia, gold crowns are highly effective for molar teeth where appearance is less of a concern.

Key Features:

• Extremely durable and resistant to wear
• Requires less tooth removal during preparation
• Gentle on surrounding teeth, reducing the risk of wear

Considerations:

The main drawback of gold crowns is their metallic appearance, which makes them less suitable for visible teeth. They are also typically more expensive due to the cost of the material itself.

Starting Price: $2,000

5. Composite Resin Crowns – The Affordable, Temporary Solution

Composite resin crowns are made from a tooth-coloured resin material, often used for temporary crowns while waiting for a permanent crown to be fully fabricated. They can also serve as permanent crowns in cases where cost is a significant factor, though they are less durable than porcelain, zirconia, or metal crowns.

Key Features:

• More affordable than other types of crowns
• Aesthetic appearance similar to natural teeth
• Quick and easy to apply

Considerations:

Composite resin crowns are more prone to chipping, staining, and wear over time, especially when used on back teeth. They are generally recommended for short-term use or in situations where budget constraints are a priority.

Starting Price: $600

How to Choose the Right Dental Crown for You

When deciding which type of dental crown is right for you, consider the following factors:

• Location of the Tooth: Crowns for front teeth often prioritise aesthetics, making porcelain or zirconia crowns ideal. For molars, gold or PFM crowns may be preferred due to their strength.
• Durability Needs: If you need a crown for a tooth that experiences a lot of pressure from chewing, zirconia or metal crowns are excellent choices.
• Aesthetic Preferences: If maintaining a natural appearance is important, porcelain crowns or porcelain-fused-to-metal crowns are great options.
• Budget: Composite resin crowns offer an affordable solution, while materials like gold and zirconia come at a higher cost.
• Allergies or Sensitivities: If you have metal sensitivities, consider all ceramic or zirconia crowns, which are metal-free and biocompatible.

Step-by-Step Understanding of the Dental Crown Procedure

The dental crown procedure is a straightforward method designed to restore a tooth’s function and appearance that is damaged or decayed. Typically, it requires two visits to the dental clinic, though some advanced practices can provide same-day crowns using cutting-edge technology. Here’s a step-by-step overview of what to expect during the dental crown procedure.

Step 1: Initial Consultation and Assessment

The process begins with an initial consultation with your dentist. During this appointment:

• The dentist examines your natural tooth structure and surrounding teeth.
• X-rays may be performed to assess the extent of the damage, check for tooth decay, and evaluate the health of the tooth’s roots and the surrounding bone.
• If there’s significant damage or an infection, a root canal treatment may be recommended before proceeding with the crown.

Key Takeaway: This step helps determine if a dental crown is the right treatment or if other dental procedures are needed first.

Step 2: Tooth Preparation

Once it’s confirmed that a crown is needed, the dentist will prepare the affected tooth. This step involves:

• Numbing the Area: Local anaesthesia is applied to ensure you’re comfortable during the procedure.
• Shaping the Tooth: The dentist reshapes the tooth by removing a portion of the enamel to make space for the crown. The amount of tooth removal depends on the type of crown (e.g., metal crowns require less tooth removal than porcelain crowns).
• Restoring Damage: In cases of severe damage or decay, the dentist might need to reinforce the tooth using filling material to establish a strong foundation for the crown.

Key Takeaway: Proper tooth preparation ensures a snug, comfortable fit for the crown, preventing future dental issues.

Step 3: Taking Dental Impressions

After the tooth is prepared:

• The dentist takes an impression of the reshaped tooth and the surrounding teeth using dental putty or a digital scanner.
• These impressions are forwarded to a dental lab where skilled technicians create your custom crown.
• The dentist will choose the appropriate shade for the crown to ensure it blends seamlessly with your natural teeth, particularly for porcelain or ceramic crowns.

Key Takeaway: Accurate impressions are crucial for ensuring the crown fits perfectly and integrates seamlessly with your smile.

Step 4: Placing a Temporary Crown

Since it takes about 2–3 weeks for the dental lab to fabricate your permanent crown:

• A temporary crown is fitted over the prepared tooth to safeguard it while waiting for the permanent crown.
• Temporary crowns are usually made from resin crowns or acrylic materials and are secured with temporary dental cement.

Care Tips for Temporary Crowns:

• Steer clear of sticky or hard foods that may cause the crown to become dislodged.
• Be gentle when brushing and flossing around the temporary crown.

Key Takeaway: Temporary crowns help maintain tooth function and appearance while waiting for the final crown.

Step 5: Fitting and Placing the Permanent Crown

Once your permanent crown is ready, you’ll return to the dental clinic for the final placement:

• The dentist will remove the temporary crown and thoroughly clean the tooth.
• The permanent crown is secured onto the tooth to check the fit, bite, and colour match with your surrounding teeth.
• Adjustments are made if necessary to ensure comfort and proper alignment.
• When everything is perfect, the crown is permanently cemented using strong dental cement.

Key Takeaway: This step ensures your crown feels natural, functions well, and blends aesthetically with your smile.

Step 6: Final Adjustments and Bite Check

After the crown is cemented:

• The dentist checks your bite to ensure there are no high spots or discomfort when chewing.
• Minor adjustments can be made to the crown’s shape if needed.

You’ll be advised to schedule a follow-up appointment if any discomfort persists, especially if the crown feels too high or affects your bite.

Key Takeaway: A proper bite alignment prevents future issues like jaw pain or wear on the crown and surrounding teeth.

 

 

What to Expect After the Procedure

After your crown is placed:

• You may experience mild sensitivity to hot or cold for a few days.
• Avoid chewing hard foods until the anaesthesia wears off to prevent accidental injury.
• Practise good oral hygiene to maintain the health of the crown and surrounding teeth.

Key Takeaway: With proper care, regular dental check-ups, and good oral hygiene, dental crowns can last 10–15 years or even longer.

Are Dental Crowns Covered by Insurance?

Many dental insurance plans partially cover dental crown treatments, especially when medically necessary, such as for restoring damaged teeth, post-root canal protection, or supporting a bridge. However, crowns placed for cosmetic reasons often have limited or no coverage. To avoid unexpected costs, check your policy details or contact your insurer to confirm coverage, including any limits or exclusions. Your dental clinic can also provide a pre-treatment estimate to clarify potential out-of-pocket expenses.

Effective Ways to Maintain the Longevity of Your Dental Crowns

Dental crowns are durable, but they require proper care to maintain their function, appearance, and longevity. Whether porcelain, zirconia, or metal, good oral hygiene helps prevent issues like decay, gum disease, or crown damage. Here’s how to keep them in top condition.

1. Practise Good Oral Hygiene

While dental crowns cover and protect a damaged or decayed tooth, the tooth underneath is still vulnerable to decay, especially around the gumline. To maintain the health of both your crown and the surrounding teeth:

• Brush Twice Daily: Clean around the crown with a soft-bristled toothbrush and fluoride toothpaste, paying extra attention to the gumline where plaque builds up.
• Floss Daily: Carefully floss between your teeth and around the crown to eliminate plaque and food debris. Floss threaders or interdental brushes can help with hard-to-reach areas.
• Use Antibacterial Mouthwash: Rinsing with an antibacterial mouthwash helps reduce bacteria, promoting healthy gums and preventing tooth decay.

Key Tip: Be gentle when brushing and flossing, especially around temporary crowns, to avoid dislodging them.

2. Avoid Hard and Sticky Foods

Crowns are strong, but they’re not indestructible. Certain foods can cause damage, particularly to porcelain crowns or composite resin crowns. To prevent cracks, chips, or loosening:

• Avoid hard foods like ice, hard candies, or nuts.
• Refrain from biting down on non-food items such as pens or fingernails.
• Limit sticky foods like caramel, chewing gum, or toffee, which can pull at the crown, especially if it’s a temporary one.

Key Tip: If you have a habit of chewing on hard objects, be mindful to protect your crown from unnecessary stress.

3. Address Teeth Grinding (Bruxism)

If you grind or clench your teeth, a condition known as bruxism, it can place excessive pressure on your crowns, causing fractures or wear over time. To protect your crowns:

• Speak to your dentist about getting a custom night guard to wear while sleeping.
• Manage stress, which can often contribute to teeth grinding.

Key Tip: Regular dental check-ups will help your dentist identify early signs of bruxism and recommend appropriate treatments.

4. Schedule Regular Dental Check-Ups

Routine dental visits are mandatory to monitor the health of your crowns and detect any potential problems early. During these visits, your dentist will:

• Check the integrity of your crown to ensure it’s not cracked, loose, or worn down.
• Assess the health of your gums and the underlying tooth structure.
• Have your teeth professionally cleaned to eliminate plaque and tartar buildup.

Key Tip: Aim for a dental check-up every six months or as recommended by your dentist.

5. Watch for Signs of Crown Issues

While crowns are designed to last for many years, problems can occasionally arise. Contact your dentist if you experience any of the following:

• Tooth Sensitivity or Pain: This may indicate an issue with the fit of the crown, tooth decay under the crown, or problems with the nerve of the tooth.
• Loose Crown: A crown can become loose due to weakened dental cement or underlying tooth issues.
• Chipped or Cracked Crown: Small chips in porcelain crowns can sometimes be repaired, but larger cracks may require crown replacement.
• Gum Inflammation or Recession: This could expose the edges of the crown, increasing the risk of decay.

Key Tip: Don’t overlook any discomfort around a crowned tooth, as early treatment can help prevent more serious dental issues.

6. Maintain a Tooth-Friendly Diet

Your diet plays a crucial role in maintaining both your oral health and the longevity of your dental crowns. To support healthy teeth and gums:

• Choose calcium-rich foods like dairy, leafy greens, and almonds to strengthen teeth.
• Consume a variety of fruits and vegetables to promote saliva production and minimise plaque buildup.
• Stay hydrated by drinking plenty of water to help rinse away food particles and bacteria.

Key Tip: Reduce your intake of sugary and acidic foods, as they result in tooth decay, particularly around the edges of your crown.

7. Protect Your Crown During Sports

If you participate in contact sports or activities with a risk of impact to your mouth:

• Wear a custom-fitted mouthguard to protect your teeth and crowns from injury.
• Replace your mouthguard as needed to ensure it provides proper protection.

Key Tip: Mouthguards not only protect your dental crowns but also help prevent serious injuries like knocked-out teeth or jaw fractures.

How Long Do Dental Crowns Last?

With good care, dental crowns can last between 10 to 15 years or even longer. The lifespan of your crown depends on factors like:

• The material used (e.g., zirconia crowns tend to last longer than resin crowns).
• Your oral hygiene routine and commitment to regular dental visits.
• Lifestyle habits, such as avoiding harmful behaviours like teeth grinding or chewing on hard objects.

When Should You Replace a Dental Crown?

While crowns are durable, they may eventually need to be replaced due to:

• Wear and tear over time
• Cracks or chips that compromise the crown’s function
• Decay developing under the crown
• Gum recession exposes the tooth’s root or crown margin

During routine check-ups, your dentist will evaluate the condition of your crown and suggest a replacement if needed.

Wrapping Up: What You Need to Remember

Choosing the right dental crown depends on your needs, budget, and oral health goals. Whether you opt for porcelain, zirconia, or gold crowns, each type offers different benefits in terms of strength, durability, and appearance. The dental crown cost varies based on materials and procedures, but investing in high-quality crowns can significantly enhance your dental health and natural tooth structure.
