When a tooth is too damaged for a filling or veneer, but its root is still intact, a dental crown may be the ideal solution. Crowns are among the most commonly recommended dental prosthetics used in both restorative and cosmetic dentistry. They not only strengthen compromised teeth but also enhance their appearance, making them a long-term solution for several dental issues.
In this blog, we’ll walk you through what dental crowns are, the different types of dental crowns, how they’re installed, and what to expect in terms of cost.
What is a dental crown?
A dental crown is a tooth-shaped “cap” that completely covers and protects a damaged or decayed tooth. Unlike veneers, which only cover the front surface, crowns wrap around the entire tooth to restore its strength, shape, and appearance. They’re often used when a tooth has lost too much structure for a filling or veneer to be effective.
Crowns are indicated in cases where:
- A tooth is broken, worn down, or severely decayed.
- A devitalized (dead) tooth needs reinforcement after a root canal.
- Teeth have large, unsightly fillings or discoloration.
- The appearance of the smile needs to be improved by correcting shape, alignment, or color.
In some cases, if the remaining tooth structure is minimal, a post may be placed inside the root to provide proper support before placing the crown.
The different types of dental crowns
There are several types of dental crowns, each offering specific benefits and drawbacks. The choice depends on the condition of your tooth, the crown’s location, your aesthetic preferences, and budget. Below are the most commonly used materials:
1. Temporary resin dental crowns
- These are short-term solutions placed while waiting for the final crown.
- Made of acrylic or resin.
- Protects the tooth and helps the gums heal during crown fabrication.
- Less durable, meant only for temporary use.
2. Metal crowns
- Made of gold, palladium, or other metal alloys.
- Extremely durable and resistant to wear.
- Best suited for molars or teeth that are not visible when smiling.
- Least aesthetic option due to metallic color.
- Often more affordable compared to ceramic options.
3. Metal-ceramic (Porcelain-Fused-to-Metal) crowns
- Consist of a strong metal base covered with tooth-colored ceramic.
- Combine durability with a more natural look.
- More affordable than all-ceramic crowns.
- Aesthetics may reduce over time as gums recede and the metal edge becomes visible.
4. All-ceramic (Metal-Free) crowns
- Made entirely of high-strength, tooth-colored ceramic.
- Offer the best aesthetics with excellent translucency, mimicking natural enamel.
- Ideal for front teeth and patients concerned about metal allergies.
- More expensive and less suited for areas with heavy biting forces.
5. Composite resin crowns
- Made of tooth-colored composite materials.
- Less expensive than ceramic or metal crowns.
- Not as durable; more prone to chipping or wear.
- Commonly used as a temporary or interim solution.
The crown placement process
Installing a crown involves several stages, usually over two appointments:
- Tooth preparation
- The dentist reshapes the tooth under local anesthesia to make room for the crown.
- The dentist reshapes the tooth under local anesthesia to make room for the crown.
- Impressions
- A mold or digital scan is taken of the tooth and surrounding teeth.
- A temporary crown is placed while the permanent one is fabricated.
- Crown fabrication
- In a dental lab or using in-office CEREC technology.
- The crown is designed to match the size, shape, and color of your natural teeth.
- Final placement
- The crown is cemented permanently onto the prepared tooth.
- The crown is cemented permanently onto the prepared tooth.
Advantages of dental crowns
- Restore function and aesthetics of damaged or decayed teeth.
- Strong and long-lasting, allowing normal chewing and speaking.
- Cemented in place, providing greater stability than removable dentures.
- Improve smile appearance by correcting color, shape, and alignment.
Lifespan of a dental crown: How long does a dental crown last?
One of the most common questions patients ask is, “How long does a dental crown last?” The answer depends on several factors, including the material used, oral hygiene habits, and overall dental health.
On average, dental crowns last between 10 to 15 years. However, with proper care, some crowns—especially those made from high-quality materials like porcelain or metal—can last 20 years or longer.
Factors that affect the lifespan of a dental crown:
- Material type:
- Metal crowns tend to last the longest due to their strength and resistance to wear.
- Porcelain-fused-to-metal (PFM) and all-ceramic crowns offer a natural look but may not be as durable in high-bite-pressure areas.
- Resin crowns typically have the shortest lifespan due to their lower strength.
- Oral hygiene:
Brushing twice a day, flossing daily, and visiting your dentist regularly helps prevent decay and gum disease, which can weaken the tooth under the crown. - Habits:
Avoiding habits like teeth grinding (bruxism), chewing ice, biting nails, or using teeth to open packages can significantly extend the crown’s life. - Tooth location:
Crowns on back molars endure more pressure and may wear down faster than those on front teeth.
If your crown becomes loose, cracks, or shows signs of wear, it’s important to visit your dentist promptly. Routine dental check-ups can help monitor your crown’s condition and ensure it lasts as long as possible.
Things to consider before getting a crown
- Irreversible procedure: The tooth must be filed down permanently to fit the crown.
- Material matters: Crowns made of harder materials than enamel may wear down opposing teeth.
- Contraindications:
- Gum disease or cavities must be treated beforehand.
- Bruxism (teeth grinding) may damage ceramic crowns unless a protective night guard is worn.
Conclusion
There’s no one-size-fits-all solution when it comes to crowns, which is why it’s important to understand the different types of dental crowns and what each offers. From metal and metal-ceramic to all-ceramic and resin crowns, your dentist will help you choose the best option based on your dental needs and personal preferences.
Whether you’re aiming to restore function, enhance your smile, or protect a weakened tooth, the right crown can make a world of difference. If you’re unsure about which type suits you best, consult your dentist for a professional evaluation and treatment plan.
