Most dental crowns last about 10 to 15 years, and many last 20 years or more with good care. How long yours lasts depends mainly on the crown material, where it is in your mouth, your oral hygiene, and habits like teeth grinding.
Dental crowns work a bit like helmets for your teeth. They protect damaged teeth, restore their function, and improve the appearance of your smile.
If you have a crown, or you are considering one, you have probably wondered: “How long do dental crowns last?” The answer depends on several factors, which we cover in this guide.
Whether you are researching dental crowns in Vancouver or are simply curious about crowns, here is what you need to know.
What Exactly Is a Dental Crown?
A crown is a tooth-shaped cap that is placed over a natural tooth and covers it completely. If you have heard both terms, see our explanation of the difference between a crown and a cap. A tooth may need a crown:
- To protect a tooth after a root canal
- To repair a cracked or broken tooth
- To cover a tooth with a large filling
- To improve the look of a discoloured or misshapen tooth
- To support a dental bridge
The material used for your crown plays a big role in how long it is likely to last.
So, How Long Do Dental Crowns Last?
On average, dental crowns last around 10 to 15 years. With good oral care and regular check-ups, many crowns last 20 years or longer.
Here is a general guide by material:
- Metal crowns (gold or other alloys): The most durable option. They rarely chip and often last 20 years or more.
- Porcelain-fused-to-metal (PFM) crowns: Strong and tooth-coloured on the outside. They commonly last 10 to 15 years or longer.
- All-ceramic or all-porcelain crowns: The most natural-looking option, often used for front teeth. They typically last 10 to 15 years.
- Zirconia crowns: Tooth-coloured and very strong, making them a popular choice for back teeth. They can last 15 years or more.
These ranges are averages. The skill of your dental team and how well you care for your crown make a big difference to the result.
How Long Does a Crown Last on a Molar vs a Front Tooth?
Crowns on molars handle the heaviest chewing forces, so they tend to wear faster and are more likely to chip or loosen than crowns on front teeth. That is why stronger materials such as zirconia or metal are often recommended for back teeth. Crowns on front teeth face less force, so appearance usually guides the choice of material, and a well-made all-ceramic crown can last many years there.
Factors That Affect How Long a Crown Lasts
Several factors determine the lifespan of your crown:
1. Oral Hygiene
Brushing twice a day and flossing daily are essential. The crown itself can’t decay, but the natural tooth underneath it can. If plaque builds up along the edge of the crown, it can lead to decay under the crown or gum disease, which are among the most common reasons crowns fail.
2. Diet Choices
Hard foods (like ice, nuts, or hard candy) and sticky foods (like caramel or toffee) put extra stress on a crown. Try to avoid chewing these with your crowned tooth.
3. Grinding or Clenching Teeth
Grinding or clenching your teeth at night (bruxism) wears crowns down and can crack them. Wearing a custom night guard helps protect both your crowns and your natural teeth.
4. Bad Habits
Using your teeth as tools, such as opening packages or biting your nails, can crack or damage a crown.
5. Regular Dental Visits
Regular check-ups let your dentist catch small problems, such as a worn edge or early decay at the margin of the crown, before they become bigger ones.
Tips to Make Your Crown Last Longer
Now that you know what affects a crown’s lifespan, here are simple tips to help yours last as long as possible:
- Brush and floss daily, paying attention to the gumline around the crown
- Use fluoride toothpaste to protect the natural tooth under the crown
- Avoid very hard and sticky foods to prevent chips and loosening
- Wear a night guard if you grind your teeth to protect your investment
- See your dentist regularly to stay ahead of any problems
These simple habits go a long way in preserving your crown and preventing future dental issues.
When Should You Replace a Crown?
Even with great care, no crown lasts forever. You may need a replacement if:
- The crown becomes loose or falls off
- You have pain or sensitivity around the crowned tooth
- There is visible damage, such as cracks or chips
- Your gums have receded and the edge of the crown is showing
If your dentist recommends a replacement, acting early can prevent more serious problems later.
Frequently Asked Questions About How Long Crowns Last
How long does a dental crown last on average?
Most dental crowns last about 10 to 15 years. With good oral hygiene, regular check-ups, and protection from grinding, many last 20 years or more.
Which type of crown lasts the longest?
Metal crowns, such as gold, are generally the longest-lasting and often last 20 years or more. Zirconia crowns are a strong tooth-coloured option that can also last 15 years or longer.
How long does a crown last on a molar?
Molar crowns handle heavy chewing forces, so they can wear faster than crowns on front teeth. Choosing a strong material such as zirconia or metal, and wearing a night guard if you grind, helps a molar crown last longer.
How long does a temporary crown last?
A temporary crown is only meant to protect your tooth for a short time, usually a few weeks, until your permanent crown is ready. If it comes loose, contact your dentist.
Can a crown last a lifetime?
Some crowns last for decades, but most eventually need to be replaced because of normal wear, gum changes, or decay around the edge. Good home care and regular dental visits give your crown the best chance of a long life.
