How Long Do Dental Crowns Last?

If you are considering a crown, or already have one, one of the first questions you probably have is: how long do dental crowns last? On average, a dental crown lasts between 10 and 15 years, and many last 20 years or longer with good care. The exact lifespan depends on the material, where the crown sits in your mouth, and how well you look after it.

At BH Dental NY, Dr. Leslie Azran and the team place custom crowns for patients in Harlem and Brooklyn, and help them keep those crowns lasting as long as possible.

How Long Do Dental Crowns Last on Average?

Most dental crowns last 10 to 15 years. With excellent oral hygiene and regular checkups, it is common for crowns to last 20 years or more. Some crowns fail earlier, usually because of decay at the edge of the crown, a cracked crown, or heavy grinding. The good news is that most of these causes are preventable.

Dental Crown Lifespan by Material

The material your crown is made from has a real impact on how long it lasts. Here is a comparison of the most common options:

Lifespans are general estimates. Your dentist can recommend the best material based on the location of the tooth, your bite, and your goals.

What Affects How Long a Dental Crown Lasts?

Oral Hygiene

A crown protects the tooth, but the natural tooth underneath can still decay, especially where the crown meets the gumline. Brushing twice a day and flossing daily are the single best ways to extend the life of your crown.

Teeth Grinding and Clenching

Grinding puts constant pressure on crowns and can cause chips, cracks, or early wear. If you grind your teeth, especially at night, a custom nightguard can protect your crown and your natural teeth.

Eating Habits

Chewing ice, hard candy, or opening packages with your teeth can crack even a strong crown. Very sticky foods can also loosen a crown over time.

Crown Location

Crowns on back teeth handle more chewing force than crowns on front teeth, so they may wear faster, which is one reason stronger materials are often chosen for molars.

Quality of Placement

A well-fitted crown that seals tightly against the tooth is far less likely to allow bacteria underneath. Precise fit and a good bite alignment make a big difference in longevity.

Signs Your Dental Crown May Need to Be Replaced

• Pain or sensitivity around the crowned tooth
• A crown that feels loose or shifts when you chew
• Visible cracks, chips, or wear on the crown
• A dark line or gap at the gumline
• Gum swelling or irritation around the crown
• A bad taste or odor from the area

If you notice any of these signs, schedule a visit promptly. A loose or damaged crown can allow bacteria to reach the tooth underneath, which can lead to decay or infection and may require additional treatment.

How to Make Your Dental Crown Last Longer

1. Brush twice a day and floss daily, paying extra attention to the gumline around the crown.
2. See your dentist every six months for exams and professional cleanings.
3. Avoid chewing ice, hard candy, and non-food items.
4. Wear a nightguard if you grind or clench your teeth.
5. Do not use your teeth as tools, such as for opening bottles or packaging.
6. Address problems early, since small issues are easier and less costly to fix.

What Happens When a Crown Wears Out?

When a crown reaches the end of its life, your dentist can usually remove it, check the tooth underneath, and place a new crown. If the underlying tooth has been badly damaged or lost, a dental implant may be a long-term replacement option. You can explore all of the restorative options we offer on our services page.

Frequently Asked Questions

How long do dental crowns last?

Dental crowns typically last 10 to 15 years, and many last 20 years or longer with proper care, regular dental visits, and good oral hygiene.

Can a dental crown last a lifetime?

It is possible, particularly with durable materials like gold or zirconia and excellent care, but most crowns eventually need to be replaced due to normal wear. Regular checkups help you catch problems early and get the longest life possible.

Do crowns on back teeth wear out faster?

They can, since molars handle the heaviest chewing forces. Stronger materials are often recommended for back teeth to compensate.

Can a tooth decay under a crown?

Yes. The crown covers the tooth, but the natural tooth structure at the edge of the crown is still vulnerable to decay. Good brushing, flossing, and regular exams help prevent this.

How do I know if my crown needs to be replaced?

Common signs include pain, looseness, cracks, a visible gap at the gumline, or gum irritation around the crown. Your dentist can examine the crown and take X-rays to confirm.

What is the difference between a crown and a bridge?

A crown covers a single damaged tooth, while a bridge replaces one or more missing teeth by anchoring a false tooth to crowns on the neighboring teeth.

Is it better to replace a failing crown or get an implant?

It depends on the condition of the natural tooth underneath. If the tooth is still healthy enough to support a new crown, replacement is often the simplest option. If it is badly damaged, an implant may be the better long-term solution. An exam is the best way to know.
