Maintaining the Permanence of Dental Crowns: Key Tips for Durability and Aesthetic Quality

Ever wondered how long a dental crown can last? Dental crowns are a popular solution for restoring damaged teeth, but their longevity is often a concern. You’re not alone in wanting a durable fix for your smile.

In this article, you’ll discover the factors that contribute to the lifespan of a dental crown and how you can extend its longevity. Whether it’s material choice or your dental hygiene habits, you’ll learn how to ensure your dental crown remains in top shape for years to come. Keep reading to find out all you need to know about the permanence of dental crowns.

Factors Affecting the Longevity of Dental Crowns

When considering the durability of your dental crowns, material choice is pivotal. Options range from metal alloys and porcelain to a combination of porcelain fused to metal (PFM) and newer composite resin materials. Metal crowns typically offer superior strength, whereas porcelain can be favoured for its aesthetic appeal which closely mimics your natural teeth.

Environmental factors play a significant role as well. Poor oral hygiene can lead to issues like gum disease, which undermines the foundation where your crown is seated. Similarly, habits such as bruxism or teeth grinding can exert excessive force, leading to potential cracks or chips.

Quality of dental work cannot be overlooked. The precision with which your crown is crafted and fitted directly correlates with its longevity. An impeccable fit minimises the risk of decay forming at the margins where the crown meets the tooth, ensuring that your crown stays secure for as long as possible.

Here are some factors to bear in mind:

  • Material selection: Determines strength and appearance
  • Oral environment: Good hygiene and avoidance of damaging habits are necessary
  • Professional fitting: A high-quality fitting will reduce future complications

Remember, routine dentist appointments allow for monitoring and maintenance of your dental crowns, enabling prompt action should any issues arise, thus prolonging their lifespan. Keep in mind, every smile has its own story, and your individual lifestyle choices will influence the endurance of your dental work.

Choosing the Right Material for Your Dental Crown

When you’re considering a dental crown, understanding the types of materials available and their respective benefits is essential. Your choice will significantly influence the performance and longevity of the crown.

Gold Alloys

Gold alloy crowns are a mixture of gold, copper, and other metals. They offer a level of durability that is difficult to match, resisting wear and tear over time.

  • Exceptional Strength: Withstands heavy biting forces
  • Biocompatibility: Low risk of allergic reactions

Porcelain Fused to Metal (PFM)

Combining the strength of metal with the aesthetics of porcelain, PFM crowns provide a balanced solution.

  • Natural Appearance: Matches adjacent teeth color
  • Robust Structure: Metal base supports porcelain overlay

All-Ceramic or Porcelain

All-ceramic or all-porcelain crowns offer the best natural color match and are an excellent choice for front teeth restorations.

  • Highly Aesthetic: Blends seamlessly with your natural teeth
  • Metal-Free: Ideal for patients with metal allergies or sensitivities


Zirconia crowns are known for their exceptional strength and have become increasingly popular due to their durability.

  • Aesthetic and Durable: Combines cosmetic appeal with resilience
  • Less Tooth Removal: Requires less tooth structure to be removed during preparation

Stainless Steel

Primarily used as temporary measures or for children’s teeth, stainless steel crowns are cost-effective and prevent further decay during the interim period.

  • Temporary Solution: Can be used while a more permanent crown is being made
  • Low Cost: An affordable option for short-term use

Selecting the right material for your dental crown involves weighing these attributes against your specific needs, budget, and the advice of your dentist. Each material has its unique set of characteristics that make it suitable for different scenarios. For instance, if you have a history of bruxism—teeth grinding—a gold alloy or zirconia crown might be the ideal choice due to their strength and durability. On the other hand, if your concern is primarily cosmetic, an all-porcelain crown can provide the most natural looking results.

Proper Dental Hygiene for Maintaining Dental Crowns

Maintaining your dental crowns is crucial to ensure they last as long as possible. Proper dental hygiene plays a vital role in extending the life of your crowns and preventing the need for replacements. Effective oral care helps protect the integrity of both the crown and the underlying tooth structure.

Regular Brushing and Flossing

To keep your dental crowns in top condition, you must adhere to a strict oral hygiene regimen which includes:

  • Brushing twice a day with a fluoride toothpaste
  • Flossing daily to remove plaque from along the gum line and between teeth
  • Using an interdental brush specifically for areas around your crown

Use of Non-Abrasive Toothpaste

When brushing:

  • Opt for a non-abrasive toothpaste to avoid scratching the crown’s surface
  • Consider using a soft-bristled toothbrush which is gentle on both natural teeth and crowns

Regular Dental Check-Ups

Regular dental visits are essential for crown maintenance:

  • Aim for check-ups and cleanings every six months, or as recommended by your dentist
  • These visits allow early detection of any issues with your crowns or natural teeth

Avoiding Harmful Habits

Several habits can compromise your crowns:

  • Refrain from using your teeth as tools to open packages or bottles
  • Avoid chewing on hard objects such as ice, pens, or fingernails

By following these guidelines, you’ll help ensure that your dental crowns remain as durable and aesthetically pleasing as the day they were fitted. Your dentist can provide personalised advice tailored to the specific material of your crowns, ensuring you get the most out of your investment in dental health.

The Importance of Regular Dental Check-Ups

Preserving the durability of your dental crowns is fundamentally tied to regular dental check-ups. Scheduled visits to your dentist are crucial for early detection of potential issues that could compromise your dental work.

  • Dentists can spot decay forming under or around the crown, which is invisible to the naked eye and could lead to the necessity for a crown replacement if not addressed promptly.
  • Regular check-ups include professional cleanings that remove plaque and tartar build-up, safeguarding the margins of the crown.
  • Your dentist will ensure the crown’s fit and integrity remain intact, averting any loosening or damage that can be caused by daily wear and tear.

During these appointments, your dentist will also check your overall oral health, examining gums, adjacent teeth, and the underlying bone structure. This holistic assessment is vital since issues like gum disease or bone loss can indirectly affect the longevity of your crowns.

Moreover, your dentist possesses the tools and expertise to polish your crowns, ensuring they maintain their aesthetic quality alongside their protective function. This attention to detail not only keeps your smile looking great but also contributes to the health and stability of your crowns.

By committing to these regular examinations, you’re not just taking care of your crowns but also investing in the long-term health of your entire smile. Regular feedback and guidance from your dental professional empower you to adapt your home care routine to better support the endurance of your dental crowns.

How to Extend the Lifespan of Your Dental Crown

Maintaining your dental crowns properly ensures they last as long as possible. By adhering to key care strategies, you’ll maximise their durability and functionality.

Practice Good Oral Hygiene
Consistent and proper oral hygiene is paramount. Brush twice daily using a fluoride toothpaste and floss around your dental crown to keep plaque away. Bacteria and plaque buildup can lead to decay under the crown, so targeted cleaning is crucial.

Avoid Hard Foods
Chewing hard foods might damage your crowns. Avoid items like ice, hard candy, and popcorn kernels. Opt for softer alternatives to prevent chipping or dislodgement.

Wear a Night Guard
If you grind your teeth at night, you’re risking your crowns’ integrity. Custom-fitted night guards protect them from the pressure and wear caused by grinding.

Regular Dental Visits
Dentists spot issues that aren’t apparent to you. At regular visits, they’ll check for signs of wear or loosening and can carry out necessary adjustments.

By incorporating these care tips into your routine, you ensure your dental crowns retain their strength, appearance, and protective qualities for years. Remember that direct feedback from your dental professional is invaluable in tailoring these practices to your specific needs.


Taking care of your dental crowns is crucial for their longevity. Embrace good oral hygiene habits, steer clear of hard foods and consider a night guard if teeth grinding is an issue. Remember, regular dental appointments are your best bet for keeping your crowns in top shape. Stick to these care tips and you’ll enjoy a smile that’s not only healthy but also visually appealing for the long haul.
