A dental crown can restore a tooth’s shape, size, and strength. Whether you already have a crown or if your dentist is talking about getting you one, you likely want to know how long it will last. The lifespan of a crown depends on a few different factors, from the material it’s made from to your daily habits.
With proper care, a dental crown can last anywhere from five to 20 years or even longer. Understanding the factors involved can help you get the most out of your dental work and keep your smile healthy.
What Is a Dental Crown & Why You Might Need One
Think of a dental crown as a cap for a weak or damaged tooth. It covers the entire visible part of a tooth and sits at the gum line. Your dentist cements the crown into place. Dental crowns can also be used to improve the aesthetics of existing teeth.
Common Reasons for a Crown
- To protect a tooth with a large filling
- To restore a broken or worn-down tooth
- To hold a dental bridge in place
- To cover a tooth after certain procedures
- To improve the look of a misshapen or discoloured tooth
Different Crowns & Their Lifespans
The material used for your crown plays a big part in how long you can expect it to last. As your dentist in Okotoks, we can help you decide on a material that fits your needs. We use modern technology like CEREC to help find a solution that works for you and your family.
Porcelain-Fused-to-Metal Crowns
These crowns offer a natural look combined with good durability. They typically last between 5 and 15 years. The metal underneath provides strength, while the porcelain exterior matches your other teeth. These crowns were used a lot in the past but are less common now.
All-Ceramic or All-Porcelain Crowns
These are common choices for front teeth because they look very natural. You can expect these crowns to last from 5 to 15 years with proper care. They also blend in seamlessly with your smile. These crowns provide the best aesthetics.
Gold Alloy Crowns
These crowns are strong and gentle on opposing teeth. They can last for 15 years or even longer. Their durability makes them a good option for back molars.
Zirconia Crowns
Zirconia is a strong material that resists wear. These crowns can last between 10 and 20 years. They offer both great strength and a pleasing appearance.
Factors That Affect Your Crown’s Longevity
Beyond the material, several other factors influence how long your crown will serve you. Good habits can add years to your crown’s life.
Your Oral Hygiene Routine
Good brushing and flossing are important for your crown. They prevent plaque from building up around the crown and gum line. This helps protect the tooth underneath from decay. Even though you have a crown covering your tooth, you still need to care for it as any other tooth.
Your Daily Habits
Habits like grinding your teeth—also known as bruxism—can put extra stress on a crown. Chewing on hard items like ice or pens can also cause your crown to crack or break. Being mindful of these habits can help protect your dental work.
The Location of the Crown
Crowns on your back teeth—your molars—do a lot more chewing and grinding. This means they might wear down faster than crowns on your front teeth.
Signs You May Need a New Crown
It’s important to know what to look for so you can address any issues early. Contact your dentist if you notice any changes.
- Pain, discomfort, or sensitivity around the crowned tooth
- A visible crack, chip, or large wear spot on the crown
- A dark line that appears at your gumline where the crown meets the tooth
- The crown feels loose or moves when you chew or touch it
Can a Tooth Decay Under a Crown?
Yes, the natural tooth under a crown can still get a cavity. If the seal between your crown and tooth breaks down, bacteria can get in and cause decay. This is why regular check-ups with your dentist are so important for your oral health.
The Replacement Process
If your crown needs to be replaced, the replacement process is straightforward. Your dentist will remove the old crown and check the health of the tooth underneath. Then they’ll prepare the tooth for a new crown to be placed.
How to Care for Your Crown & Make It Last
You can help your crown last for years by taking a few simple steps. Consistent care protects both your investment and your oral health. Make sure to:
- Brush your teeth twice a day with fluoride toothpaste & floss daily.
- Avoid chewing on very hard foods—like ice or hard candy—with your crowned tooth.
- Wear a mouthguard at night if you grind your teeth.
- Keep up with regular dental cleanings & check-ups.
