Zirconia crowns are one of the most durable and aesthetically pleasing options in modern dentistry. Many people considering this type of dental restoration wonder, “How long do zirconia crowns last?”
This comprehensive guide will explore the lifespan of zirconia crowns, factors that influence their durability, and how to extend their longevity. Whether you already have a zirconia crown or are considering getting one, this article will provide you with everything you need to know. If you are looking for expert dental care, visiting an NHS Dentist in Aberdeen can help you maintain your crown and overall oral health effectively.
What Is a Zirconia Crown?
A zirconia crown is a type of dental crown made from zirconium dioxide, a ceramic material known for its exceptional strength and biocompatibility. These crowns are used to restore and protect damaged or weakened teeth. Unlike traditional metal or porcelain crowns, zirconia crowns offer durability and a natural appearance.
Why Choose Zirconia Crowns?
- Highly durable – Resistant to cracks and fractures
- Aesthetic appeal – Matches natural teeth in colour
- Biocompatible – Less likely to cause allergic reactions
- Minimal wear – Gentle on surrounding teeth
- Stain-resistant – Does not discolour over time
Because of these benefits, zirconia crowns are a long-lasting solution for dental restoration and are commonly used for both front and back teeth.
How Long Do Zirconia Crowns Last?
On average, a zirconia crown lasts between 10 to 20 years. Some crowns can last even longer with proper oral hygiene and regular dental check-ups.
Zirconia crowns are among the longest-lasting dental restorations, making them a great investment in your oral health.
Factors That Affect the Lifespan of Zirconia Crowns
Several factors influence how long a zirconia crown lasts. Understanding these can help you take better care of your crown.
1. Oral Hygiene Routine
A proper oral hygiene routine helps prevent plaque buildup and gum disease. Brushing twice a day, flossing daily, and using antibacterial mouthwash are essential for keeping your crown in good condition.
2. Teeth Grinding or Clenching (Bruxism)
Grinding or clenching your teeth, known as bruxism, puts extra pressure on your crown, leading to premature wear. If you grind your teeth, wearing a custom night guard can help protect your crown.
3. Diet and Eating Habits
Your diet plays a role in the lifespan of your crown. Avoid chewing on hard foods like ice, nuts, or hard candies, as these can damage the crown. Sticky foods like caramel should also be avoided, as they may loosen the crown over time.
4. Placement of the Crown
Crowns placed on the molars (back teeth) endure more chewing pressure than those on front teeth. However, zirconia’s high strength makes it ideal for molars.
5. Dentist’s Skill and Placement
A well-fitted crown placed by an experienced dentist lasts longer. Poorly placed crowns may cause discomfort or fail prematurely.
6. Gum and Bone Health
If you develop gum disease, your gum line may recede, exposing the edge of the crown and making it more prone to damage. Keeping your gums healthy ensures that your crown remains intact for a longer period.
Signs That a Zirconia Crown Needs Replacement
Even though zirconia crowns last for many years, they may eventually need replacement. Here are some signs that indicate it may be time for a new crown:
1. Sensitivity or Pain
If you experience pain or sensitivity, it could mean the crown is damaged or that decay has developed underneath.
2. Visible Cracks or Wear
Although rare, cracks or chipping can occur over time, especially if you grind your teeth or bite on hard foods.
3. Loose Crown
If the crown feels loose while eating or brushing, it may need to be re-cemented or replaced.
4. Gum Recession
Gum recession can expose the base of the crown, making it vulnerable to decay.
If you notice any of these signs, visit your dentist for an evaluation. Early detection can help prevent further complications.
How to Extend the Life of Your Zirconia Crown
To maximise the lifespan of your zirconia crown, follow these simple tips:
1. Maintain Good Oral Hygiene
- Brush twice daily with fluoride toothpaste
- Floss daily to remove plaque around the crown
- Use an antibacterial mouthwash to prevent gum disease
2. Avoid Hard and Sticky Foods
- Avoid chewing ice, hard candies, and nuts
- Do not eat sticky foods that can loosen the crown
- Cut food into smaller pieces instead of biting directly
3. Wear a Night Guard
If you grind or clench your teeth, wear a night guard to protect your crown.
4. Visit Your Dentist Regularly
- Get dental check-ups every six months
- Have your crown checked for wear or damage
- Get professional cleanings to keep your gums healthy
5. Avoid Using Teeth as Tools
Do not use your teeth to open packages, bite fingernails, or tear tape. This can damage the crown and cause it to fail sooner.
