If you have a dental crown, or you are about to get one, it is natural to wonder how long it will last. A crown is an investment in your smile, so it makes sense to want to protect it. Knowing how long dental crowns last, and what you can do to extend their life, helps you get the most from your treatment.
The honest answer is that a crown’s lifespan depends on several factors, from the material it is made of to how well you care for it. With the right habits, many crowns last well over a decade, and some last much longer.
What Is a Dental Crown?
A dental crown is a custom made cap that fits over a damaged or weakened tooth. It restores the tooth’s shape, strength, and appearance, allowing you to bite and chew normally.
Crowns are used in many situations, such as protecting a tooth after a root canal, restoring a cracked tooth, or covering a large filling. You can learn more on our crowns and bridges page.
How Long Do Dental Crowns Last on Average?
Most dental crowns last somewhere between ten and fifteen years. That said, this is only an average, and the real figure varies from person to person.
Some crowns wear out sooner due to heavy use or grinding, while others remain in great condition for twenty years or more. How well you look after the crown and the tooth beneath it makes a major difference.
It helps to think of the lifespan as a range you can influence rather than a fixed expiry date. Two people can receive identical crowns on the same day, yet one may last far longer simply because of better daily care and consistent dental visits.
What Affects How Long a Crown Lasts?
Several factors influence the lifespan of a crown. Understanding them helps you take steps to protect yours.
The Material of the Crown
Crowns can be made from different materials, each with its own balance of strength and appearance. Your dentist will recommend the option that best suits the location and function of the tooth.
For a highly visible front tooth, a natural looking material is often the priority, while a hard working back tooth may call for something especially strong. Matching the material to the job helps the crown both look right and last well.
Where the Crown Is in Your Mouth
Crowns on the back teeth take on more force from chewing, so they may wear faster than crowns on teeth near the front. The amount of daily pressure a crown handles affects how long it lasts.
Your Daily Oral Care
A crown protects the tooth, but the tooth and gum underneath still need care. Decay can form at the edge of a crown if plaque is allowed to build up, which can shorten its life.
Healthy gums matter too. If the gum line recedes, the margin of the crown can become exposed, which may affect both its appearance and its seal. Gentle, consistent brushing and flossing help keep this area healthy.
Habits Like Grinding
Grinding and clenching place extra strain on crowns and can cause them to wear or crack. If you grind your teeth, protecting the crown becomes even more important.
Signs Your Crown May Need Attention
A crown does not last forever, and there are signs that suggest it may need to be checked or replaced.
Watch for these signs:
- sensitivity or discomfort around the crowned tooth
- a crown that feels loose or moves slightly
- a visible chip, crack, or worn area
- a dark line or gum changes near the edge of the crown
If you notice any of these, it is best to have the crown checked before a small issue becomes a larger one.
How to Make Your Dental Crown Last Longer
The good news is that you have a lot of control over how long your crown lasts. A few simple habits go a long way.
Keep Up Good Oral Hygiene
Brush twice a day and clean between your teeth daily, paying attention to the gum line around the crown. This helps prevent decay where the crown meets the tooth.
Protect Against Grinding
If you grind your teeth at night, a custom night guard can protect both your crown and your natural teeth from unnecessary wear.
Be Careful With Hard Foods
Avoid chewing ice, hard candy, and other very hard items, as these can chip or crack a crown just as they can a natural tooth.
Keep Regular Dental Visits
Routine dental checkups and dental cleanings let your dentist catch early problems and keep the tooth beneath the crown healthy.
What Happens When a Crown Wears Out?
When a crown reaches the end of its life, it can usually be replaced with a new one. The process is similar to having the original crown made.
In some cases, the tooth underneath may need extra care first, such as a new tooth coloured filling or, if decay has reached the inner tooth, a root canal. Your dentist will check the tooth and recommend the right approach. If a crown comes off suddenly, our dental emergency care team can help.
Can a Crowned Tooth Still Get a Cavity?
This is one of the most common questions people ask, and the answer surprises many. Yes, a tooth with a crown can still develop a cavity.
The crown itself cannot decay, but the natural tooth underneath it can. Decay usually starts at the margin, the line where the crown meets the tooth, if plaque is allowed to gather there. This is exactly why brushing, flossing, and regular cleanings remain so important even after a tooth is crowned.
The reassuring news is that decay at this stage is often caught early during a routine exam, when it is simple to treat. Skipping visits, on the other hand, can let a small problem grow unnoticed beneath the crown.
How Technology Improves Modern Crowns
Today’s crowns are more precise and longer lasting than ever, thanks to advances in dental technology.
Comfortable digital oral health scans capture an accurate 3D model of your tooth without messy impressions, which helps ensure a better fit. A well fitting crown is less likely to trap plaque or fail early. Restorations can also be crafted with precision dental 3D printing, improving both accuracy and comfort.
Paying for a Dental Crown
Cost is often part of the decision, and we believe in being clear about it from the start. Many dental plans cover part of the cost of a crown, and the amount can vary.
You can find more details under insurance and financing options, and if you do not have private coverage, you may qualify through the Canadian Dental Care Plan.
