Dental crowns, often called “tooth crowns,” are powerful tools that benefit patients seeking functional and aesthetic improvements. These remarkable dental restorations can breathe new life into damaged teeth, boosting your confidence and oral health. But how long can you expect your dental crown to last?

The average lifespan of dental crowns depends on several factors, and understanding them is essential for achieving long-lasting results. Dental crown maintenance and proper care play a vital role in maximising the longevity of your dental crown, and your lifestyle choices can significantly impact its success rate.

When selecting the right type of crown, dentists have an array of materials at their disposal. Choosing between durable metal crowns and aesthetically pleasing porcelain crowns should align with your specific needs and preferences. Temporary crowns, often made from composite resin, are also available during dental crown procedures.

Beyond the initial selection, the factors affecting dental crown lifespan extend to your health habits and oral hygiene routines. Proper oral hygiene practices are paramount to maintaining the health of your natural teeth and crowns alike. Regular checkups with experienced dentists provide early detection of potential concerns and offer valuable guidance on treatment options.

While dental crowns are a beacon of dental health, certain harmful habits and health conditions may impact their longevity. The effects of teeth grinding, for instance, can strain the crown’s structure, leading to pain and potential infections. Therefore, extra care and dental crown maintenance are necessary to safeguard your investment.

In this blog post, we will delve deep into each of these aspects, providing you with an in-depth exploration of the factors influencing dental crown lifespan.

Understanding Dental Crowns and Their Purpose

Natural teeth sometimes need extra support to maintain functionality and appearance. This is where dental crowns come into play. Dental crowns, also known as tooth caps, are custom-made prosthetic restorations that cover the entire surface of a tooth, from the gum line to the biting surface.

The primary purpose of dental crowns is to provide strength, protection, and aesthetic enhancement to damaged or compromised teeth. They act as a shield, safeguarding the underlying tooth structure and preventing further deterioration.

There are several reasons why people may need dental crowns. One common reason is to restore broken or fractured teeth. A dental crown can restore strength and functionality if a tooth is damaged due to trauma or decay. By encasing the damaged tooth, the crown provides stability and durability, allowing you to bite and chew without discomfort.

Decayed teeth can also benefit from dental crowns. When a tooth is extensively decayed and a traditional dental filling is insufficient to restore it, a crown can be placed to provide a more comprehensive choice. The crown is a protective barrier, preventing further decay and preserving the natural tooth structure.

Furthermore, dental crowns play a crucial role in enhancing the appearance of your smile. Dental crowns can be an option for achieving a beautiful and harmonious smile if you have discoloured, misshapen, or poorly aligned teeth. The crowns are custom-designed to match your natural teeth’s colour, shape, and size, resulting in a seamless and natural-looking restoration.

The Expected Lifespan of A Dental Crown: Setting Realistic Expectations

When investing in dental crowns, it is natural to wonder how long they will last and provide you with their intended benefits. While it’s impossible to be certain, understanding the average lifespan of dental crowns and the factors that can influence their duration can help set practical expectations.

On average, dental crowns have a lifespan of 10 to 15 years. It’s important to note that this is a general estimate, and individual experiences may vary. Various factors can influence the longevity of dental crowns, making it difficult to predict an exact timeframe. However, understanding these common factors affecting dental crown lifespan is crucial for maintaining their longevity and reaping the benefits of dental crowns.

  • Dental Crown Maintenance:
    Proper oral hygiene practices are paramount for the health and durability of dental crowns. Regular brushing and flossing help prevent plaque buildup and maintain a clean environment around the crowns. Good oral hygiene reduces the risk of decay, gum disease, and other issues that could impact the longevity of the crowns.

  • The type of crown:
    The quality, construction, and type of material used in making the crown can impact its lifespan.

  • Dental Habits:
    Using teeth to perform tasks like opening bottle caps, tearing threads, or chewing on hard objects such as ice or pencils can diminish the crown’s longevity.

  • Regular Dental Check-ups:
    Regular visits to your dentist are crucial for maintaining the health and longevity of your dental crown. It’s important to schedule routine check-ups, professional cleanings, and examinations to detect any potential issues early on and provide necessary treatments or adjustments for the longevity of your crown.

  • Dentist’s skills:
    The dentist’s proficiency in tooth preparation, impression or scanning techniques, and using digital scanners for accuracy can affect the crown’s durability.

  • The health of the affected tooth:
    If the tooth has good overall health, longer roots, and healthier surrounding gums and bone, the crown and tooth will likely have a better prognosis.

  • Diet:
    Certain foods and beverages can impact dental crown lifespan. Acidic foods and drinks like citrus fruits and sodas can erode the crown material over time. Similarly, excessive consumption of sugary or sticky foods increases the risk of decay and undermines the integrity of the crowns.

  • Individual health conditions:
    Certain health conditions, such as diabetes or autoimmune disorders, can affect oral health and the lifespan of dental crowns. These conditions may compromise the body’s ability to fight infections or maintain optimal oral hygiene, making regular dental care and monitoring even more critical.

How Proper Dental Crown Maintenance Contributes to Lifespan

Maintaining good oral hygiene habits is crucial for the health of both your natural teeth and dental crowns. Brushing your teeth at least twice daily with fluoride toothpaste helps clear plaque and food particles that can accumulate around the crown. Pay attention to the area where the crown meets the gum line to prevent bacteria buildup and potential gum inflammation. Daily flossing also helps remove plaque and debris between teeth and around the crown for a clean and healthy mouth.

In addition to personal oral hygiene habits, regular professional cleanings are essential. Professional cleanings performed by your dentist eliminate plaque and tartar that cannot be cleared by regular brushing and flossing. These cleanings help maintain the health of your gums and prevent periodontal issues that could impact the longevity of your dental crowns.

Materials Matter: The Impact of Crown Type on Lifespan

The choice of material plays a significant role in the lifespan of dental crowns. Different types of dental crowns offer varying degrees of strength, durability, aesthetics, and longevity.

  • Zirconia:
    Zirconia crowns are a type of ceramic crown made from zirconium dioxide. Known for their remarkable strength and resistance to fractures, zirconia crowns can last 10-15 years or longer with proper care. However, the fit of zirconia crowns may not be as precise as other options. Zirconia is a type of ceramic material that is milled from a solid block using computer-aided design and computer-aided manufacturing (CAD/CAM) technology. The milling process may result in minor discrepancies in the crown’s shape and contour, which can affect how well it fits over the prepared tooth.

  • Porcelain fused to metal (PFM):
    PFM crowns combine the natural-looking appearance of porcelain with a metal substructure. They are commonly used for front teeth due to their aesthetic appeal. Although PFM crowns can be expected to last 5-15 years on average, porcelain is prone to chipping, and the metal margin may become visible as gums recede over time.

  • Lithium disilicate:
    Made of lithium and silicon, lithium disilicate is a strong glass ceramic material. These crowns can be fabricated in-office using distinctive equipment, allowing for same-day placement. With proper dental care, lithium disilicate crowns can last 5-15 years or longer. They offer cosmetic appeal, precise fit at margins, and reliable bonding to teeth.

  • Gold:
    Gold crowns are renowned for their strength, resistance to chipping and cracking, and ideal fit. While their natural appearance may not be desirable for visible teeth, they are often chosen for molars. Gold crowns can last for decades with proper care. It is common for gold to be combined with other metals to enhance strength while reducing costs.

The Role of Dental Habits in Maximising Dental Crown Durability

Certain habits can significantly impact the lifespan and durability of dental crowns. Understanding the influence of these habits is essential for maintaining the longevity of your dental restorations.

  • Teeth grinding (bruxism):
    Habitual teeth grinding or clenching, known as bruxism, can exert excessive force on dental crowns. The constant pressure and grinding motion can wear down the crown’s surface over time, causing cracks, fractures, or dislodgement. During sleep, bruxism is particularly damaging, as you may be unaware of the habit. A custom mouthguard, recommended by your dentist, can protect the crowns from excessive grinding forces and enhance their durability.

  • Chewing hard foods or objects:
    Biting down on hard foods like ice, nuts, or hard candies can place undue stress on dental crowns. These forces can potentially cause the crown material to chip, crack, or even dislodge from the underlying tooth.

  • Using teeth as tools:
    Using your teeth as tools can be detrimental to both your natural teeth and dental crowns. Opening bottles, tearing packages, or biting on hard objects can exert excessive force on the crown, leading to chips or dislodgement. It is important to remember that dental crowns are designed for chewing and biting food, not for performing non-dental tasks.

How Regular Dental Checkups Influence the Lifespan of Dental Crowns

Regular dental checkups play a crucial role in maintaining the lifespan and durability of dental crowns. These routine examinations allow dentists to monitor the condition of the crowns and identify any potential issues early, so you can maximise the benefits of dental crowns. They carefully evaluate the crowns’ fit, stability, and integrity, checking for proper alignment with the surrounding teeth and gums.

Dentists also inspect the margins or edges of the crowns, confirming a tight and secure fit to prevent bacteria accumulation and potential complications. By detecting signs of wear, damage, or material degradation, dentists can intervene promptly to prevent further deterioration and address dental issues to extend the lifespan of dental crowns. Patients can harness the benefits of dental crowns for a longer period by maintaining regular dental checkups.

In addition to monitoring the crowns, regular checkups often include professional cleanings. As mentioned above, professional cleanings can help clear plaque, tartar, and other buildup around the crowns. This meticulous cleaning not only promotes optimal oral health but also contributes to the longevity of the restorations.

Coping with Dental Crown Issues: What to Do When Problems Arise

While dental crowns are designed to be durable and long-lasting, occasional issues may arise. It’s important to know how to recognise and address these problems promptly to secure the continued success of your dental crowns.

  • Discomfort or sensitivity:
    If you experience discomfort or sensitivity around a dental crown, it may be due to an improper bite or gum inflammation. Contact your dentist so they can adjust the crown’s fit, check the occlusion (how your teeth come together), or address any underlying gum issues to alleviate the discomfort.

  • Damage or fracture:
    If you notice a chip, crack, or break in your crown, contact your dentist immediately. Avoid chewing on that side, and keep the area clean. Your dentist will assess the extent of the damage and recommend appropriate treatment options, such as crown repair or replacement.

  • Crown dislodgement:
    If a dental crown becomes loose or completely comes off, it is important not to try to reattach it yourself. Keep the crown safe and contact your dentist as soon as possible. They will evaluate the crown and the underlying tooth structure to determine the most suitable course of action, which may involve re-cementing the crown or providing a new crown if necessary.

  • Inflammation or infection:
    In some cases, gum inflammation or infection may develop around a dental crown, leading to redness, swelling, or discomfort. Maintaining good oral hygiene, including gentle brushing and flossing around the crown, can help manage mild cases. However, if the symptoms persist or worsen, it is important to see your dentist for a thorough evaluation and appropriate treatment, which may include professional cleaning or antibiotic therapy.

  • Changes in colour or appearance:
    Over time, dental crowns may experience changes in colour or appearance due to staining or wear. Regular dental cleanings and good oral hygiene practices can help minimise discolouration. If you are unhappy with the appearance of your crown, discuss your concerns with your dentist. They can explore options such as professional cleaning, polishing, or, if necessary, crown replacement to restore the desired appearance.

When Is It Time to Replace a Dental Crown?

Dental crowns are designed to be durable, but they may require replacement over time due to various factors. It’s important to recognise the signs that indicate a dental crown may need replacement and understand the process involved.

  • Decay:
    Dental crowns protect weakened or damaged teeth but are not immune to decay. If decay occurs around the edges or beneath the crown, it may be necessary to extract the crown, address it, and replace it with a new crown.

  • Poor fit or discomfort:
    A well-fitted dental crown should feel comfortable and stable in your mouth. If you experience persistent discomfort, a change in bite or the crown feels loose; it may indicate a need for replacement. A proper fit is crucial for the crown to function effectively.

  • Aesthetic concerns:
    Over time, the appearance of a dental crown can be affected by wear, discolouration, or changes in surrounding natural teeth. If you are dissatisfied with the aesthetics of your crown, it may be an appropriate time to consider replacing it for an improved look.

Final Thoughts

When it comes to dental crown lifespan, several factors come into play. Understanding these factors and taking proactive measures can contribute to the longevity and success of your dental crowns. By considering key aspects such as proper maintenance, material choice, dental habits, regular checkups, and timely interventions, you can maximise the benefits of dental crowns and enjoy a confident and healthy smile for years to come.
