Protecting a weakened or damaged tooth starts with choosing a crown that can withstand daily use while keeping your tooth secure for years. Materials and design play a major role in how well a crown performs and how long it continues to shield your natural tooth.
At El Segundo Modern Dentistry & Orthodontics, we match each crown material to your tooth’s specific needs. Our goal is to restore strength while supporting everyday comfort. This approach helps your treated tooth stay stable and protected over time.
In this guide, you’ll learn how crown materials differ, what affects durability, and how to choose an option that fits your aesthetic goals, lifestyle, and oral health needs.
What Makes a Dental Crown Durable?
Durability in a dental crown depends on the material used, how well you care for it daily, and how effectively it protects your tooth. These factors work together to keep your crown strong and your tooth healthy for many years.
Key Materials and Their Lifespan
Dental crowns come in different materials, and each affects how long your crown lasts. Gold crowns are the strongest and can last up to 20 years or more with proper care. They resist wear and rarely chip, but their color makes them less common for front teeth.
Porcelain crowns are popular because they look like natural teeth and blend well with your smile. They can last 10 to 15 years but need more care to avoid chipping. Some crowns use a mix of ceramic and resin, offering a balance between strength and appearance.
Daily Habits That Impact Longevity
How you treat your dental crown every day affects how well it lasts. Avoid biting on hard objects like ice, pens, or hard candies, as these can crack or damage the crown material.
Good oral hygiene is key. Brush twice a day and floss to keep your gums and teeth healthy. This lowers the chance of gum disease or decay around the crown’s edges, which could weaken its hold.
Regular dental checkups let your dentist spot any early issues. This way, small problems don’t turn into bigger ones that threaten your crown.
Signs of Effective Tooth Protection
A durable dental crown should fit well and feel comfortable when you chew or bite. You shouldn’t notice sharp edges, pain, or pressure when you eat.
Your crowned tooth should be free from sensitivity or swelling, which can show if the crown is protecting the tooth beneath properly. If your crown stays firmly in place and matches your other teeth in color and shape, it’s working as it should.
Comparing Crown Options for Long-Lasting Tooth Protection
Choosing the right crown can protect your tooth for many years while keeping your smile healthy. Different materials offer varying strengths, looks, and durability. Knowing the basics helps you make the best choice for your needs.
Porcelain-Fused-to-Metal Crowns
Porcelain-fused-to-metal (PFM) crowns combine a metal base with a porcelain coating. The metal gives strong support, helping the crown withstand biting forces. Porcelain on the outside looks like your natural tooth, which helps with appearance.
Though strong, the metal under the porcelain can sometimes show through, causing a dark line near the gum. These crowns are a good option if you want a mix of strength and a natural look, especially for back teeth. PFM crowns last about 10 to 15 years if you care for them well.
All-Ceramic Crowns
All-ceramic crowns are made fully of tooth-colored materials without metal. They offer the most natural look because they mimic the shine and translucence of real teeth.
These crowns are a great choice for front teeth, where appearance is important. They also work well for people with metal allergies. While ceramic is strong, it may not be as durable for heavy biting forces as metal-based crowns.
The lifespan of all-ceramic crowns often ranges from 10 to 15 years. With proper care, they protect your tooth from decay and damage while blending seamlessly with your smile.
Gold Alloy Crowns
Gold alloy crowns are made mainly of gold mixed with other metals. Gold is the most durable crown material, resisting wear and fractures well. These crowns last the longest, often 20 years or more. They also cause minimal wear on the teeth that bite against them, preserving your natural bite.
While they don’t look like natural teeth, their strength and longevity make them ideal for back teeth, where your bite force is strongest.
Innovative Materials Enhancing Crown Durability
Choosing the right material for your dental crown can make a big difference in how long it lasts and how well it protects your tooth. Materials like zirconia and E.max lithium disilicate offer strong, natural-looking options to keep your smile healthy and comfortable.
Zirconia Crowns
Zirconia crowns are known for their strength and toughness. This material is a type of ceramic that can handle strong biting forces without breaking. It’s also biocompatible, meaning it is gentle on your gums and unlikely to irritate.
These crowns look natural but have extra toughness that many other types don’t offer. Zirconia crowns are less likely to wear down over time, making them a durable choice for back teeth where chewing pressure is high.
E.max Lithium Disilicate Crowns
E.max lithium disilicate crowns are prized for their combination of strength and beauty. This glass ceramic material looks very close to natural tooth enamel, giving you an attractive, lifelike appearance.
Despite their delicate look, these crowns are quite strong and durable. They resist fractures well, making them a good choice for front and back teeth. E.max crowns also bond closely to your tooth, which adds extra protection against decay.
Material | Strength | Appearance | Best For |
Zirconia | Very strong | Natural-looking | Back teeth, high pressure |
E.max Lithium Disilicate | Strong, durable | Highly aesthetic | Front and back teeth |
How Material Hardness Influences Wear on Opposing Teeth
Harder crown materials can resist fractures but may cause added wear on the tooth that bites against them. The Centers for Disease Control and Prevention (CDC) notes that balancing durability with natural tooth preservation is key to long-term oral health.
Materials like zirconia provide excellent strength, while lithium disilicate offers more flexibility and is gentler on opposing enamel. Understanding these interactions helps you choose a crown that supports durability without stressing nearby teeth.
Your dentist evaluates your bite and chewing patterns to ensure the material supports comfortable function.
Choosing the Right Crown for Your Needs
Picking a dental crown means thinking about how it looks, how strong it is, and what fits your budget and lifestyle. You want a crown that lasts, feels comfortable, and protects your tooth properly.
Balancing Aesthetics and Strength
Crowns come in different materials, each with its own look and durability. Porcelain crowns match your tooth color well, so they’re great for front teeth. They blend in naturally but may wear down faster when used on biting surfaces.
Metal crowns, like gold or other precious metals, are very strong and last a long time. They are better for back teeth, where you need more strength but don’t mind the color difference.
Some crowns combine porcelain over metal. These offer both a natural look and solid protection. Discuss what matters most to you with your dentist so they can recommend the right type for your smile and strength needs.
Cost Considerations
Your budget plays a role in choosing a crown. Porcelain and porcelain-fused-to-metal crowns tend to cost more because of their appearance and manufacturing process. Metal crowns can be less expensive while offering strong protection.
Insurance often covers part of the cost, but coverage depends on your plan. Investing in a durable crown can save you money by avoiding future repairs or replacements.
Lifestyle and Oral Health Factors
Your daily habits affect which crown fits you best. If you grind your teeth, metal crowns or porcelain fused to metal may resist damage better. For those with sensitive gums or allergies, certain materials might work better.
Think about your bite, chewing habits, and how much you use each tooth. Your dentist will also check your overall oral health, like gum condition and tooth decay risk, to choose a crown that supports healing and lasting protection.
Tips for Maximizing Crown Lifespan
Taking good care of your dental crown can help keep it strong and protect your tooth longer. Paying attention to how you clean your teeth and knowing when to visit your dentist play big roles in making your crown last.
Oral Care Best Practices
Brush twice a day gently, using a soft-bristled toothbrush and fluoride toothpaste. Floss daily to remove plaque from areas a brush can’t reach. Avoid biting hard things like ice or popcorn kernels, as these can crack or wear down your crown.
Rinsing with an antibacterial mouthwash can also help reduce germs that cause decay around the crown. Be mindful if you grind or clench your teeth; wearing a night guard can protect your crown from extra pressure while you sleep.
Keeping your natural teeth and gums healthy supports your crown’s strength. Regular hygiene habits prevent issues that might shorten your crown’s lifespan.
When to See Your Dentist
Schedule regular dental exams every six months to have your crown checked for signs of wear or damage. If you feel tenderness, sensitivity, or notice your crown feels loose, call your dentist promptly. Avoid waiting, as early treatment often requires less invasive work.
Prompt professional care helps maintain your crown’s function and prevents discomfort or infection.

Is there a difference in longevity between front teeth crowns and molar crowns?
Yes. Molars handle more chewing pressure, so dentists often use metal or zirconia crowns for those teeth. Front teeth crowns need to look natural, so dentists usually choose porcelain or porcelain-fused-to-metal, which may not last as long under heavy use.
What are the potential drawbacks of getting a dental crown?
Crowns can cause tooth sensitivity after placement. They may need replacement after several years due to wear or damage. Dentists might need to remove some healthy enamel to prepare a tooth for a crown.
How much do different dental crown materials typically cost?
Metal crowns usually cost more but last longer. Porcelain crowns look more natural and often cost more. Zirconia crowns generally fall between porcelain and metal crowns in price. Insurance coverage and the dentist’s location also affect the total cost.
What is the latest advancement in dental crown materials?
Zirconia crowns offer strong durability and improved appearance compared to older materials. Dental labs now use CAD/CAM technology to create crowns in the office, providing faster and more precise results.
Can you explain the difference between a tooth cap and a crown?
A tooth cap and a crown are the same thing. Both cover a damaged or weak tooth to protect it and restore its shape and function. People may use either term depending on where they are or who they talk to.
