How Long do Crowns Last

How long do crowns last? To avoid misleading patients into believing that their crowns are indestructible or immortal, crowns should last between 5 and 15 years. Many insurance companies will cover the cost of a crown replacement if it fails after 5 to 8 years.

How long do crowns last?

The average lifespan of dental crowns

:small_blue_diamond: While no dentist can promise that your crowns will endure for a specific number of years, we can look at some general statistics based on the hundreds of patients who get dental crowns each year.

:small_blue_diamond: A dental crown can last anywhere from five to fifteen years on average. This is based on data acquired from official dental research.

:small_blue_diamond: Damage from an accident or trauma to your jaw, as well as a high-sugar diet, are all common reasons for having your dental crowns replaced sooner than expected. You should also examine elements that may have a detrimental impact on your crowns, such as your bite force or any tooth grinding habits you may have. These concerns may have an impact on the longevity of your crowns.


On average, a dental crown lasts between five and fifteen years. Crowns are frequently changed sooner than intended because of damage from an accident or trauma to the jaw, as well as a high-sugar diet. It would help if you also looked into factors that could harm your crowns, including your biting force and grinding habits.

Composition of dental crowns

:small_blue_diamond: Another thing to consider is the makeup of your dental crowns or the materials from which they are produced. It’s a good idea to discuss your alternatives with your dentist before deciding on the material used to create your dental crown.

:small_blue_diamond: If you’re seeking the most long-lasting alternative for your treatment, gold crowns may be the way to go. According to statistics, gold crowns survive 96 percent of the time after a decade of use.

:small_blue_diamond: However, you must evaluate the appearance of your crowns from an aesthetic standpoint. If you have crowns placed on your molars in the rear of your mouth, they will be almost completely hidden from view.

:small_blue_diamond: If you need crowns for your front teeth, porcelain fused to a mental crown is a good option. These are pretty durable and attractive, with a good 90 percent lasting ten years with no problems.

:small_blue_diamond: Metal-free ceramic crowns are arguably the most popular alternative. Although newer than gold and porcelain/metal crowns, they have the best aesthetics and can endure up to ten years when properly prepared.

Porcelain fused to a mental crown is a fantastic alternative if you need crowns for your front teeth. Gold crowns survive 96 percent of the time after a decade of use, according to statistics. Ceramic crowns, which do not include any metal, are by far the most common option.

What distinguishes a porcelain dental crown from other crowns?

:small_blue_diamond: Porcelain, ceramic, metal alloys, composite resin, and porcelain fused to metal are some materials that can be used to produce dental crowns. The majority of dental crowns are designed to match the color of your teeth.

:small_blue_diamond: The material used for your dental crown will be determined by criteria such as the tooth’s position in your mouth, your gum tissue, your personal preference, and the color of the tooth receiving the dental crown.

:small_blue_diamond: Some people prefer porcelain dental crowns because they may be made to seem almost identical to the natural tooth. Porcelain also enables the tooth to function normally again. On the other hand, porcelain crowns can take time to make, and patients should be advised that Porcelain is not as flexible as tooth enamel, so some foods may need to be avoided once the crown is in place.


The majority of dental crowns are color-matched to your natural teeth. Some of the materials used include Porcelain, ceramic, metal alloys, composite resin, and porcelain fused to metal. Once the crown is in place, some foods may need to be avoided.

What is it like to have a dental crown?

:small_blue_diamond: Dental crowns are usually completed in two visits to the dentist. Your dentist will prepare your teeth for the crown by removing any decay and the outer area of the tooth on your first visit. If a tooth’s core has decayed to the point where it can no longer support the crown, a dentist may need to rebuild it.

:small_blue_diamond: Your dental staff will then take an impression of your tooth so that they may create an exact model for the crown. This can be done using a mold or a digital scan. While you wait for the final version to be manufactured, you can be given a temporary crown.

:small_blue_diamond: Your dentist will place the completed crown in your mouth, make any necessary modifications, and then cement it into your mouth less than two weeks later–though some dentists have the equipment to produce the crown the same day.


In most cases, dental crowns can be completed in two visits to the dentist. A temporary crown might be given to you while you wait for the final version to be made. A dentist may need to restore a tooth’s core if it has decayed to the point where it can no longer support the crown.

What to know about different types of crowns and their longevity

:small_blue_diamond: A crown’s average lifespan is roughly ten years. However, crowns made of any material can last for decades if adequately manufactured and cared for.

:small_blue_diamond: When choosing a crown, your dentist will analyze each material’s strength, durability, and aesthetics before recommending the one that is best suited to your condition.

:small_blue_diamond: Other criteria that your dentist may take into account while deciding on the optimal crown material for your tooth are:

  • the tooth’s exact location

  • what percentage of the natural tooth is still present

  • When you grin, how much of your crown will be visible

:small_blue_diamond: Let’s look at the four most frequent crowns and how long they should last.

:arrow_right: Zirconia

Zirconium dioxide, an extreme form of substance-related to titanium, is used to make zirconium dioxide crowns, classified as a sort of ceramic crown. These crowns are particularly resistant to fracture due to their endurance.

Zirconia is the most robust non-metallic material for crowns, according to Cranford. Zirconia crowns, on the other hand, do not necessarily fit as well as other crowns.

After being subjected to significant bite forces, monolithic zirconia crowns were the least likely to shatter or split. A zirconia crown can easily last 10-15 years or longer with adequate hygiene and care.

:arrow_right: Porcelain fused to metal

PFM crowns are a popular alternative that also happens to be one of the most natural-looking. As a result, they’re ideal for front teeth.

Over the last 60 years, porcelain-fused-to-metal crowns have been the most commonly prescribed cosmetic option for teeth. On the other hand, Porcelain is prone to chipping, and as gums recede, the metal margin or edge typically shows.

PFM crowns can last anywhere from 5 to 15 years on average. They might last longer if you take proper care of your teeth.

:arrow_right: Disilicate of lithium

This is a high-performance glass-ceramic made of lithium (a silvery-white metal) and silicon (a hard, crystalline solid).

Dentists can create crowns in-office using lithium disilicate and a specialized machine. This means you can acquire a crown and have it permanently attached in only one visit to the dentist’s office.

According to Cranford, dental laboratories currently state that this is the most commonly prescribed crown material.

Lithium disilicate is a highly robust material that can have its transparency modified. These crowns are aesthetically pleasing, well-inserting at the margins, and well-bonded to the teeth.
With proper care, these crowns can endure for at least 5-15 years, if not longer.

:arrow_right: Gold

For nearly a century, yellow gold has been the preferred material for crowns. This is due to its durability, resistance to chipping and breaking, and ability to form a good fit with the tooth.

In reality, according to a 2015 research study, gold is still the gold standard, with a 95 percent 10-year survival rate. A gold crown can last for decades if it is correctly cared for.

The artificial appearance of gold, on the other hand, is a disadvantage. Dentists commonly use gold for molars that aren’t apparent when you smile.

Gold is frequently combined with other metals, such as palladium, chromium, or nickel, by dentists nowadays. This not only keeps the crown strong but also saves money.


The typical lifespan of a crown is ten years. According to Cranford, zirconia is the most robust non-metallic material for crowns. PFM crowns (Porcelain fused to metal) are a popular option that also happens to be one of the most natural-looking. Using lithium disilicate and a specialized machine, dentists may make crowns in the office. These crowns are cosmetically beautiful, have a good margin fit, and firmly adhere to the teeth. These crowns can last for at least 5 to 15 years if properly cared for.

Are crowns more durable than veneers?

:small_blue_diamond: The primary distinction between a veneer and a crown is covering. A veneer covers the front of your tooth, whereas a dental crown covers the entire tooth. A crown is thicker than a veneer. Therefore there’s a difference in thickness there as well.

:small_blue_diamond: The longevity of a veneer versus a crown varies depending on the material used and your dental practices; however, veneers may not last as long as crowns because they are thinner.

:small_blue_diamond: A veneer is generally advised for cosmetic reasons. On the other hand, a crown will be more advantageous if you have any decay, cracks, or extreme wear. Your dentist will be able to tell you which type of restoration is best for you.


A veneer is a thin layer of porcelain that covers the front of your tooth, whereas a dental crown covers the entire tooth. Your dentist will be able to advise you on the best sort of restoration for you. A crown is a better option if you have decay, cracks, or significant wear on your teeth.

How will you know when it’s time to replace a crown?

:small_blue_diamond: Clinical inspection of dental X-rays is the only way to determine if a crown has to be replaced, according to Michael H. Reshad, DDS, of Sutton Place Dental Associates.

:small_blue_diamond: The crown should be replaced if there is evident degradation, either clinically or radiographically.

:small_blue_diamond: The crown should be replaced if there are any open margins where the crown isn’t positioned correctly on the tooth or a gap between the crown and the tooth.

:small_blue_diamond: It’s also a symptom that the crown needs to be changed if it’s cracked or if there’s space between the crown and the surrounding teeth where food and bacteria might accumulate.

:small_blue_diamond: The following are some of the warning indicators that a crown is nearing the end of its useful life:

  • Tooth decay is most likely the cause of pain in the tooth with the crown. As a result, the crown and the deterioration beneath it must be removed, and a new crown must be manufactured and put.

  • When chewing something sticky like gum, caramel, or even bread, you may get the sense that the crown is unstable or moving.

  • The tooth with the crown is no longer attractive; some patients prefer whiter crowns, particularly if the neighboring teeth have been whitened. They can also want to change their shape or appearance. A patient may also choose to get a crown replaced if it is chipped.


Only a clinical examination or a dental X-ray can tell if a crown needs to be changed. If there is visible degeneration, either clinically or radiographically, crowns should be replaced. The most frequent reason for pain in the tooth with the crown is dental decay.

What factors influence a crown’s longevity?

:small_blue_diamond: The type of material chosen and your dental hygiene, practices, and other lifestyle factors might affect the lifespan of a crown.

:small_blue_diamond: A thorough hygiene program is the most significant component in the longevity of a crown. This includes the following:

  • cleaning your teeth twice or three times per day

  • flossing at least once a day is recommended

  • brushing your teeth every six months

:small_blue_diamond: Other factors that can affect a crown’s lifetime include:

  • The crown’s quality, how well it’s manufactured, and the material used to make it can all affect how long it lasts.

  • The dentist’s skill set consists of factors such as how effectively the dentist prepped the tooth and took the impression or scanned the teeth, which can affect how long the crown lasts. For a single tooth, a digital scanner is more accurate than impression materials with trays.

  • The crown and the tooth will likely have a better prognosis if the damaged tooth is generally healthy with longer roots and healthier surrounding gum and bone levels.

  • Using your teeth to open bottles, tear threads, or chew on ice and pencils will shorten the life of your crown.

  • Clenching and grinding your teeth, especially at night, can wear down the surface of a crown and threaten its stability, especially if it’s made of ceramic. You might want to talk to your dentist about getting a nighttime mouthguard.


The most critical factor in ensuring the longevity of a crown is proper hygiene. The quality of the crown, how well it’s made, and the material used to construct it all impact how long it lasts. Some factors, including how well the dentist prepared the tooth, took the impression, or scanned the teeth, can influence its duration.

Frequently Asked Questions (FAQs)

The following are some frequently asked questions about how long do crowns last.

1. Can a Crown Last a Lifetime?

Although crowns are permanent, they may need to be replaced after a few years. Your crown can last you decades or perhaps a lifetime if it is done correctly, you maintain good hygiene, and take adequate care of it.

2. How long should you keep a crown on your tooth?

The position of your crown in your mouth can also impact how long your crown lasts. Some crowns can last a lifetime, while others may crack and require replacement. When properly cared for, a crown can endure anywhere from 10 to 30 years.

3. Do crowns cause tooth decay?

If a dental crown is overly abrasive, it might cause damage to surrounding teeth. It may cause irritation or even damage to surrounding or opposing teeth. If you have any pain or discomfort around your crown, contact your dentist straight away.

4. Can a crown be replaced multiple times?

Porcelain crowns, which are the most common due to their low cost, can last 15 years. Metal crowns have a 20-year or longer life expectancy. Crowns made of gold or zirconia can endure a lifetime.

5. Can a cavity form under a crown?

It’s impossible to get a cavity in your crown because it’s constructed of a specific synthetic material. However, the tooth to which your crown is affixed may develop a cavity.

6. How long do dental crowns last?

Metal crowns are the least likely to chip or shatter, last the longest in terms of wear, and need only a modest amount of tooth removal. They’re also resistant to biting and chewing. The most significant disadvantage of this sort of crown is the shiny tint. Metal crowns are a fantastic option for molars that are hidden from view.

7. Is it possible to replace a crown?

A dental crown is frequently highly long-lasting and does not need to be repaired or replaced for many years. However, you should be aware of the indicators that a dental crown has to be replaced. You may have dental discomfort and sensitivity if you neglect them.

8. Is it possible for a crown to last for 40 years?

The usual lifespan of a dental crown is between 5 and 15 years if it is correctly cared for. On the other hand, a dental crown can survive for 25 to 40 years if properly cared for.

9. What kind of crown glue do dentists use?

Zinc phosphate is regarded as one of the most reliable and long-lasting glues for permanent crowns. Glass ionomer (GI) and resin-modified glass ionomer (RMGI) are the latter two, both of which are known to be manufactured from polyacrylic acid liquid and fluoroaluminosilicate glass powder.

10. Is it possible for a crowned tooth to become infected?

Infection. If you didn’t get a root canal before getting your crown, the tooth still has nerves. When the crown presses against an injured nerve, an infection develops. Infections can also occur due to outdated fillings beneath the crown leaking bacteria that infects the nerve.


The usual lifespan is roughly 5-15 years, depending on the type of dental material utilized. Some crowns, however, can last for decades with adequate care, good tooth hygiene habits, and frequent dental check-ups.

Your dentist may discuss the cost, durability, and other benefits and drawbacks of each type of material with you to help you choose the right crown for your needs.
