A dental crown is a common way to restore a tooth’s shape, size, and strength. If you have a crown or are about to get one at Acacia Dental Centre, you likely want to know how long you can expect it to last. While there’s no single answer, a few key factors can give you a better idea of your crown’s lifespan.
With good care, most dental crowns can last between 10 and 15 years, and some materials can last even longer. This depends on the type of crown you have, your daily oral health habits, and your commitment to regular dental check-ups.
What Is a Dental Crown & Why Would You Need One?
A dental crown is a custom-made cap that fits over your entire tooth down to the gum line. It’s designed to protect the tooth underneath and restore its function, though it can also be used as a full replacement. A dentist may recommend a crown for several reasons, such as to:
- Protect a weak tooth from a fracture
- Restore a tooth that is already broken or worn down
- Cover a tooth after a root canal treatment
- Hold a dental bridge in place
- Cover a dental implant
- Improve the look of a misshapen or discoloured tooth
The Lifespan of Different Crown Materials
The material your crown is made from plays a big role in how long it will last. Most crowns last between 10 to 15 years on average, but with great care, some can last for decades. Here are the most common options:
Zirconia & Other Ceramics
All-ceramic crowns, especially those made from a strong material called zirconia, are a popular choice. They match the colour of your natural teeth well and are very durable. With proper care, these crowns can last 10 to 15 years or even longer.
Porcelain-Fused-to-Metal
Some crowns have a metal base with porcelain layered on top. This gives them the strength of metal and the natural look of porcelain. They typically last 5 to 15 years. Over time, the metal edge can sometimes show at the gum line if your gums recede.
Gold & Metal Alloys
Gold crowns are known for their strength and durability. They rarely chip or break and can last for decades. There are several types of crown materials, and gold is often used for back molars, where it isn’t visible when you smile.
Factors That Affect How Long Your Crown Lasts
In addition to the material, several other factors influence your crown’s longevity. How you care for your crown and your overall oral health are just as important as the crown itself.
Your Daily Oral Care Routine
The tooth underneath the crown can still get a cavity, especially right at the edge where the crown meets the tooth. Proper brushing and flossing help remove plaque and keep the teeth and gums healthy.
Your Personal Habits
Certain habits can shorten a crown’s life. Clenching or grinding your teeth puts extra pressure on the crown, which can cause wear or damage over time. Chewing on hard objects such as ice, pens, or hard candy can also chip or break a crown.
Regular Visits to the Dentist
Regular check-ups are key for natural teeth, and it’s no different when it comes to crowns. During an exam, your dentist can inspect your crown for any signs of problems, like looseness or hidden decay, before they become bigger issues. Professional cleanings also help keep the area around your crown healthy.
Signs You Might Need a Crown Replacement
While crowns can last a long time, they may eventually need to be replaced. If you experience sudden pain or the crown becomes loose, you may require emergency dental service. Let your dental team know if you notice any of these things:
- Pain, discomfort, or sensitivity in the crowned tooth.
- The crown feels loose, or it moves when you chew.
- You see a visible chip or crack in the crown.
- A dark line appears along your gumline.
- Your gums around the crown are sore or swollen, which can be a sign of gum disease.
Can Your Crown Last a Lifetime?
While some crowns can last for decades, it’s not possible to say one can last forever. The mouth is a tough environment with a lot of pressure from biting and bacteria. The best approach is to follow good oral health practices and care for your crown just like you would your natural teeth.
