The most common benchmark for a crown’s longevity is 5 to 15 years. But for many people, the reality is far more positive. With consistent oral hygiene and the absence of any major issues, it’s not unusual for a crown to last for 20, 25, or even 30 years. Think of this as the difference between a car’s factory warranty and its actual lifespan with proper maintenance.

How Long Do Crowns on Teeth Last, From a Molar to a Front Tooth?
Not all crowns are created equal. The material they are made from and their location in your mouth play a huge role in their durability. Here’s a quick breakdown to help you understand how these elements affect how long a crown lasts on a molar versus a front tooth.
| Factor | Impact on Lifespan |
| Location | A crown on a front tooth faces less pressure from chewing and is more focused on aesthetics. A crown on a molar (or back teeth) needs to be more durable to handle chewing and grinding forces, impacting material choice and longevity. |
| Your Habits | Habits like grinding your teeth (bruxism), chewing on ice, or using your teeth to open bottles can put extreme pressure on your crown and lead to premature failure. |
| Oral Hygiene | Brushing and flossing every day is crucial. It prevents decay from forming at the base of your crown, which can lead to its failure. |
How Long Do Crowns Last After a Root Canal or as Temporary Crowns?
Many patients are curious about specific circumstances. “How long do crowns last after a root canal?” The answer is that a root canal-treated tooth is more brittle and susceptible to fracture. The crown’s purpose is to protect that weakened tooth. So, while the crown itself may be in perfect condition, its lifespan is linked to the long-term health of the underlying tooth.
Additionally, it’s vital to remember that temporary crowns are just that—temporary. They are designed to protect your tooth for a short period while your permanent crown is being fabricated in a lab. They are not built for long-term use and must be replaced as soon as possible.
How Long Do Porcelain & Zirconia Crowns Last on Front Teeth?
The material of your crown is a primary determinant of its lifespan.
Porcelain Crowns: In contrast, porcelain crowns are chosen for their beautiful, natural appearance, making them a popular choice for front teeth, where aesthetics are a top priority. However, porcelain can be more susceptible to chipping than other materials.
Zirconia Crowns: Zirconia crowns are known for their exceptional strength and are often recommended for molars that endure heavy chewing forces. While not as aesthetic as porcelain, they are becoming increasingly popular even for front teeth due to their immense durability.
How Long Do Teeth Crowns Last if You Brush and Care for Them Every Day?
Your daily habits have a significant impact on your crown’s longevity. Brushing and flossing every day is not just for your natural teeth. It’s crucial for preventing decay from forming at the base of your crown, which can lead to its failure. If you grind your teeth in your sleep, the constant pressure can wear down your crown prematurely. A simple solution is a night guard.

Can a Permanent Dental Crown Last a Lifetime?
Yes, it is possible for a permanent dental crown to last a lifetime, but it is considered the exception rather than the rule.
While the average lifespan is typically 10 to 15 years, a crown’s longevity is highly dependent on a number of factors. A crown that lasts 25, 30, or even more years usually meets these specific conditions:
Exceptional Oral Hygiene: The person maintains an impeccable brushing and flossing routine, preventing any decay from forming around the crown’s margin.
Absence of Trauma: The crown is never subjected to a significant blow or injury that could chip or crack it.
Healthy Underlying Tooth: The natural tooth structure beneath the crown remains strong, healthy, and free of decay, and the surrounding gum tissue stays in excellent condition.
Good Patient Habits: The person avoids teeth grinding (bruxism), does not chew on hard items like ice or hard candy, and refrains from using their teeth to open bottles or packages.
Quality of the Restoration: The crown was made with a highly durable material (like zirconia or gold) and was fabricated and placed with a precise fit by a skilled dentist.
In summary, a crown that lasts a lifetime is a testament to perfect conditions and dedicated care. While it’s a great goal to aim for, most dental professionals will advise that you plan for a long and healthy lifespan (10-20+ years) and accept that a replacement may eventually be necessary.
Does material affect how long crowns last on teeth?
Yes, absolutely. For instance, a gold alloy crown is often considered the most durable, while an all-porcelain crown offers the best aesthetic but is more prone to chipping.
