most common solutions in restorative dentistry, designed to restore the shape, size, strength, and appearance of a damaged tooth. Crowns are often used when a tooth is too damaged for a filling but not damaged enough to require extraction. They can be made from a variety of materials, each offering distinct benefits depending on your needs and preferences.
In this blog, we’ll explore the different types of dental crowns available, their advantages, and how to choose the best option for you.
A dental crown is a cap placed over a tooth to restore its shape, size, and function. It completely covers the visible portion of a tooth above the gum line. Crowns are used for various purposes, including:
• Restoring a broken or damaged tooth
• Covering a large filling or cavity
• Protecting a weakened tooth
• Holding a dental bridge in place
• Improving the appearance of a discolored or misshapen tooth
There are several types of crowns available, each suited to different dental needs. Here’s a breakdown of the most common types of dental crowns:
1. Porcelain Crowns (All-Ceramic Crowns)
What Are They? Porcelain crowns are made entirely from ceramic materials. They are known for their excellent aesthetic qualities, making them a popular choice for front teeth or any visible areas.
Pros:
• Natural Appearance: Porcelain crowns are highly aesthetic and can be color-matched to your natural teeth, making them almost indistinguishable from real teeth.
• Biocompatible: Porcelain is a non-reactive material, making it ideal for patients with metal allergies or sensitivities.
• No Metal Exposure: These crowns don’t have any metal base, which avoids the potential for a visible metal line at the gum line, a common concern with metal-based crowns.
Cons:
• Less Durable Than Metal: While porcelain is strong, it is more prone to chipping or cracking compared to metal crowns, especially in areas that experience heavy chewing pressure.
• More Expensive: Porcelain crowns tend to be pricier than metal or porcelain-fused-to-metal crowns.
Best For: Porcelain crowns are ideal for front teeth or other highly visible areas where appearance is a priority. They are also suitable for people with metal sensitivities.
2. Porcelain-Fused-to-Metal (PFM) Crowns
What Are They? Porcelain-fused-to-metal crowns combine the strength of a metal crown with the aesthetic qualities of porcelain. The interior of the crown is made of metal, while the outer layer is porcelain, providing a natural look.
Pros:
• Strong and Durable: The metal base provides strength, making PFM crowns more durable than all-porcelain crowns, especially for back teeth that endure a lot of chewing pressure.
• Natural Look: The porcelain layer can be color-matched to blend with the natural teeth, offering a more aesthetic result than full metal crowns.
• Long-Lasting: PFM crowns are very durable and can last for 10-15 years with proper care.
Cons:
• Visible Metal Line: Over time, the metal base may show at the gum line, which can be a concern for people with gum recession or those who are looking for a crown that looks completely natural.
• More Invasive: To fit a PFM crown, your dentist may need to remove more of the natural tooth structure than with other materials.
Best For: PFM crowns are suitable for back teeth where durability is important, and they can also be used for front teeth when aesthetics are important but the crown needs to withstand more chewing force.
3. Metal Crowns (Gold or Other Alloys)
What Are They? Metal crowns are made from a variety of metal alloys, including gold, platinum, or non-precious metals like nickel-chromium. These crowns are known for their durability and strength.
Pros:
• Highly Durable: Metal crowns are the most durable option, lasting 15-20 years or more. They are resistant to wear and won’t crack under heavy biting forces.
• Ideal for Back Teeth: Their strength makes them ideal for molars and premolars, which endure the most pressure while chewing.
• Minimal Tooth Removal: Because metal crowns are thinner than porcelain crowns, less natural tooth structure needs to be removed during the preparation process.
• Biocompatible: Gold and other precious metals are highly biocompatible, making them safe for most people, including those with metal allergies.
Cons:
• Aesthetic Concerns: Metal crowns are very noticeable due to their metallic color. This makes them unsuitable for front teeth or visible areas where appearance matters.
• Cost: Gold and platinum crowns are generally more expensive than porcelain or PFM crowns.
Best For: Metal crowns are ideal for back teeth (molars and premolars), where durability is key, and aesthetics are less of a concern.
4. Zirconia Crowns
What Are They? Zirconia crowns are made from a highly durable ceramic material called zirconium dioxide. These crowns combine the strength of metal with the aesthetic properties of porcelain.
Pros:
• Highly Durable: Zirconia crowns are incredibly strong and resistant to wear, making them ideal for back teeth that endure heavy chewing forces.
• Aesthetic Appeal: Zirconia can be made to match the color of natural teeth, offering a more aesthetic result than metal crowns.
• Biocompatible: Zirconia is well-tolerated by the body and is a good option for those with sensitivities to other metals.
• Minimal Tooth Removal: Zirconia crowns require less tooth structure removal compared to metal crowns, making the procedure less invasive.
Cons:
• Potential for Wear on Opposing Teeth: Because zirconia is so hard, it can sometimes cause wear on the opposing teeth, particularly if they are made from porcelain.
• Cost: Zirconia crowns tend to be more expensive than porcelain or metal options, though they can be more affordable than gold crowns.
Best For: Zirconia crowns are an excellent choice for back teeth that need a durable, long-lasting solution while maintaining a natural appearance.
5. Resin Crowns
What Are They? Resin crowns are made from a plastic material, often combined with composite resins to give them a tooth-like appearance. These crowns are typically used for temporary restorations.
Pros:
• Cost-Effective: Resin crowns are one of the most affordable options available, making them a good choice for temporary fillings or for patients on a budget.
• Aesthetic: Resin crowns can be color-matched to the natural teeth, although they may not look as natural as porcelain or zirconia.
• Less Tooth Removal: Like porcelain and zirconia, resin crowns can require minimal tooth structure removal.
Cons:
• Less Durable: Resin crowns are less durable than porcelain or metal options and may wear down, crack, or stain over time.
• Not Ideal for Long-Term Use: Due to their weaker nature, resin crowns are generally used as temporary solutions rather than permanent restorations.
Best For: Resin crowns are typically used for temporary crowns or small cavities where durability is not as important.
Choosing the Right Dental Crown for You
The right type of dental crown for you depends on several factors, including:
• Location of the tooth: For visible teeth (like the front teeth), aesthetic concerns are important, so porcelain or zirconia may be the best choices. For back teeth, strength and durability are more critical, so gold, zirconia, or PFM crowns may be preferred.
• Durability needs: If you need a crown for a tooth that will experience significant chewing pressure, materials like metal, zirconia, or PFM may be the best choice.
• Budget: Porcelain and zirconia crowns tend to be more expensive, while metal and resin crowns are more affordable options.
• Personal preferences: Some patients may prefer to avoid metals or have concerns about the aesthetic appearance of metal-based crowns. In such cases, porcelain or resin options may be more suitable.
Dental crowns are a versatile solution to restore and protect damaged teeth, and the right crown for you depends on your specific needs, preferences, and budget. Whether you opt for porcelain, zirconia, metal, PFM, or resin crowns, each material offers unique advantages. Consult with your dentist to determine the best option based on your dental health and desired outcome.

Dental crowns are a common solution for restoring damaged or weakened teeth. Whether you’re considering a crown for a broken tooth, a root canal, or a cosmetic upgrade, understanding the basics can help you make an informed decision. Below are some of the most frequently asked questions about dental crowns.
1. What is a dental crown?
A dental crown is a cap that completely covers a damaged or decayed tooth to restore its shape, size, strength, and appearance. Crowns are commonly used to protect weakened teeth, restore function to broken teeth, or improve the appearance of a tooth.
2. Why would I need a dental crown?
You may need a dental crown if:
• A tooth is severely decayed or damaged and cannot be restored with a filling.
• You’ve had a root canal treatment, and the tooth is weakened.
• A tooth is cracked or broken and needs protection.
• You need to cover a dental implant.
• You have a large filling, and the remaining tooth structure is too weak to support it.
• You want to improve the appearance of a discolored or misshapen tooth.
3. How long do dental crowns last?
The lifespan of a dental crown depends on the material used and how well you care for your teeth. On average, crowns can last between 5 and 15 years. Crowns made of porcelain or zirconia may last up to 10-15 years, while metal crowns (such as gold) are known to last even longer—sometimes 20 years or more. Proper dental hygiene and regular check-ups can extend the life of your crown.
4. What types of materials are used for dental crowns?
Dental crowns can be made from several materials, each offering different benefits:
• Porcelain: Natural-looking and ideal for front teeth.
• Porcelain-fused-to-metal (PFM): A combination of porcelain and metal for added strength, ideal for back teeth.
• Gold or Metal Alloys: Durable and long-lasting, best for back teeth due to their strength and wear-resistance.
• Zirconia: A strong ceramic material that combines the durability of metal with the aesthetics of porcelain, ideal for both front and back teeth.
• Resin: Typically used for temporary crowns, less durable than other materials but affordable.
Your dentist will help you choose the best material based on the location of the tooth, aesthetic preferences, and budget.
5. Are dental crowns painful?
The process of getting a crown is typically not painful because the tooth will be numbed with local anesthesia before the procedure. Some discomfort or sensitivity may occur after the crown is placed, especially if the tooth was treated with a root canal or if the crown is placed over a sensitive area. This discomfort usually subsides within a few days. Over-the-counter pain relievers can help manage any mild discomfort.
6. How long does it take to get a dental crown?
Getting a dental crown typically requires two visits:
1. First visit: The dentist will prepare the tooth by removing any decay and shaping it to fit the crown. An impression is taken to create a custom crown, and a temporary crown is placed while the permanent one is made in a dental lab. This can take a few days to a couple of weeks, depending on the lab’s turnaround time.
2. Second visit: The dentist will remove the temporary crown and place the permanent one, making any final adjustments for a perfect fit. The procedure is usually quick and straightforward.
In some cases, same-day crowns (such as CEREC crowns) are available, which can be created and placed in a single visit using advanced technology.
7. How do I care for my dental crown?
Dental crowns require the same care as your natural teeth:
• Brush and floss regularly to keep your crown and surrounding teeth clean.
• Avoid chewing hard foods (like ice or hard candy) or grinding your teeth, as these can damage the crown.
• If you grind your teeth at night, talk to your dentist about a nightguard to protect your crown and natural teeth.
• Visit your dentist regularly for check-ups to ensure your crown is in good condition and to monitor the health of the surrounding teeth and gums.
8. Can dental crowns get cavities?
While dental crowns themselves cannot get cavities, the underlying tooth can still decay if the crown is not properly placed or if the margins of the crown become loose over time. It’s important to maintain good oral hygiene to prevent cavities in the tooth underneath the crown and to check regularly for any issues with the crown.
9. How much do dental crowns cost?
The cost of a dental crown can vary widely depending on the type of material used, the location of the crown, and your geographic area. On average, prices range from:
• Porcelain or Ceramic Crowns: Rs 10000 to Rs 15000 per crown.
• Porcelain-Fused-to-Metal Crowns (PFM): Rs 3000 to Rs 5000 per crown.
• Metal Crowns (Gold or Alloys): Rs 1500- Rs 2500 for metal crown and Rs 60000-80000 for Gold per crown.
• Zirconia Crowns: Rs 8000-Rs 12000 per crown.
10. Will my dental crown match my other teeth?
Yes, porcelain and zirconia crowns can be color-matched to your natural teeth for a seamless appearance. These materials can be tinted to blend in with the rest of your smile, making them ideal for visible areas like front teeth. If you’re getting a crown for a back tooth, you may prioritize durability over aesthetics, and a metal or PFM crown might be recommended.
11. Can I get a crown if I have a missing tooth?
If you have a missing tooth and would like to restore it, a dental implant can be used with a crown to replace the missing tooth. In this case, the implant serves as the tooth root, and the crown is placed on top to complete the restoration. This provides a natural-looking, functional replacement for a missing tooth.
12. Can a dental crown fall off?
While dental crowns are designed to stay in place, they can become loose or fall off in rare cases due to factors like:
• Wear and tear over time.
• Decay or damage to the tooth underneath the crown.
• Improper placement or bonding.
If your crown falls off, contact your dentist immediately. In some cases, the crown can be re-cemented. If the crown is damaged, a new one may be necessary.
13. How do I know if I need a dental crown?
You may need a dental crown if:
• You have a cracked, broken, or severely decayed tooth.
• You’ve had a root canal treatment, and the tooth needs reinforcement.
• You have a large filling that no longer provides adequate support.
• You want to improve the appearance of a discolored or misshapen tooth.
If you’re unsure whether a crown is right for you, schedule a consultation with your dentist, who can assess your dental needs and recommend the best course of action.
14. Are there any risks with dental crowns?
Dental crowns are generally safe, but there are a few potential risks:
• Tooth sensitivity: Some patients experience mild sensitivity after a crown is placed, but this usually subsides within a few days.
• Crown damage: Porcelain crowns can chip or crack if exposed to extreme force.
• Improper fit: If a crown doesn’t fit properly, it could cause discomfort, decay, or gum irritation.
These risks are rare, and most problems can be avoided by following your dentist’s aftercare instructions and attending regular dental check-ups.
