Dental Crowns: How Long Do They Last and When to Replace Them?

Dental crowns are one of the most common and effective restorative treatments in dentistry. They protect weakened teeth, restore function, and improve appearance. But if you already have a crown—or are considering getting one—you may be wondering: How long do dental crowns last, and when should they be replaced?

At La Mirada One Dental, we want patients to understand what to expect from their crowns and how to extend their lifespan.

How Long Do Dental Crowns Last?

On average, dental crowns last 10 to 15 years. With excellent care, some crowns can last 20 years or more.

The lifespan depends on factors such as:

• Material – Porcelain crowns offer a natural look but may wear faster than metal or porcelain-fused-to-metal crowns.

• Oral hygiene – Regular brushing, flossing, and professional cleanings prevent decay around the crown.

• Habits – Teeth grinding, chewing ice, or biting hard objects can shorten a crown’s lifespan.

• Placement – Crowns on back teeth endure more biting pressure than those on front teeth.

Signs Your Dental Crown Needs to Be Replaced

Even the most durable crown won’t last forever. Here are common signs it’s time for replacement:

• Persistent pain or sensitivity – May indicate decay under the crown or a failing root canal.

• Cracks, chips, or worn edges – Structural damage reduces protection and function.

• Looseness or movement – A crown that doesn’t fit snugly may allow bacteria inside.

• Gum recession around the crown – Exposed edges increase the risk of decay.

• Discoloration or aesthetic concerns – Older crowns may not match your natural teeth.

If you notice any of these issues, schedule an exam right away to avoid complications.

When Crowns Work Best

Dental crowns are often recommended for:

• Protecting a tooth after root canal therapy

• Restoring a tooth with a large cavity or fracture

• Covering a misshapen or severely discolored tooth

• Supporting a dental bridge

• Topping a dental implant for a natural look and function

How to Make Your Crown Last Longer

To maximize the lifespan of your dental crown:

• Brush and floss daily around the crown.

• Visit us every six months for checkups and cleanings.

• Avoid chewing on hard foods or objects.

• Wear a nightguard if you grind your teeth.

• Maintain a healthy diet to support overall oral health.
