A dental crown is a restoration that covers and protects all or part of a damaged or weakened tooth. In simple terms, a crown sits over the tooth the same way a hat sits over your head, adding strength, stability and long-term protection.
Crowns are commonly recommended when a tooth has fractured, has been heavily filled or has weakened over time. Because they play such an important role in restoring function, patients often ask how long their crown will last.
Understanding the factors that affect longevity can help you know what to expect and how to care for your crown so that it serves you well for many years. At No Gaps Dental, we guide you through every step of the process so you can feel confident and supported throughout your treatment.
Average Lifespan of a Dental Crown
Most dental crowns last between five and fifteen years. However, with excellent care, many will last longer than a decade.
While research studies often report ideal outcomes, real-life longevity depends on several important factors including the crown material, the condition of the tooth, oral habits and how well the crown is maintained.
Different patients require different materials depending on their mouth, bite and dental needs. For example:
- A full gold crown is often recommended for patients with bruxism (teeth grinding) who need a crown on a second molar.
- A full porcelain crown is preferred in the “aesthetic zone” (the visible front teeth) for a natural appearance.
- The available space between upper and lower teeth and the condition of the remaining tooth structure also influence the choice of material.
Regular dental check-ups and good oral hygiene significantly increase the lifespan of a crown. Patients who attend routine appointments and care for their teeth well often enjoy crowns that last well beyond ten years.
Crown Materials and How They Compare
Different crown materials offer different advantages. Your dentist will recommend the option that best suits the tooth location, strength requirements and aesthetic goals.
- All-Porcelain (Ceramic): This category includes materials such as lithium disilicate and zirconia.
- Lithium disilicate is ideal in the aesthetic zone due to its natural, lifelike appearance.
- Zirconia is extremely strong and is preferred for back teeth where chewing forces are higher.
- Porcelain Fused to Metal (PFM): Often used for back teeth. These crowns have a metal base fused with a layer of porcelain to improve appearance while maintaining strength.
- Full Metal Crowns: Commonly used in areas with limited space or in patients with heavy bite forces.
- Full Gold Crowns: These remain one of the best options for people who grind their teeth due to their durability and long-term performance.
Your dentist will explain the benefits of each material and help you choose the one that best suits your needs.
What Can Affect How Long a Crown Lasts
A number of factors influence how long a dental crown will last:
- Daily oral hygiene habits.
- Maintaining healthy gums.
- Presence of bruxism (grinding) or other parafunctional habits.
- The fit and placement quality of the crown.
- The condition of the tooth before the crown was placed.
- The height and strength of the remaining tooth structure.
- Presence of cracks in the underlying tooth.
- Keeping regular dental appointments and following professional advice.
Your dental team will discuss these factors with you and provide personalised recommendations to help keep your crown in excellent condition.
Tips to Help Your Crown Last Longer
Most crowns last longer when patients follow simple, consistent care habits:
- Maintain excellent oral hygiene with regular brushing and flossing.
- Attend routine dental check-ups and professional cleans.
- Follow the specific instructions provided by your dental professional.
- Maintain a balanced and healthy diet.
- Avoid biting on very hard or sticky foods (like ice or hard lollies).
- If you have bruxism, wear your occlusal splint (night guard) as directed.
- Use interdental brushes if your dentist has advised them.
- Take care of your general health, as this also affects your oral health.
With proper care, many crowns continue to function beautifully for well over a decade.
Signs a Crown May Need to Be Replaced
Eventually, a crown may need replacement if any of the following occur:
- Decay develops underneath the crown.
- The crown fractures or breaks.
- A root canal is required on the tooth after the crown is placed.
- The crown repeatedly becomes loose or dislodges.
- Improved contact is needed between the teeth for better chewing function.
If you notice discomfort, changes in your bite or any movement in your crown, it is important to have it assessed promptly.
