Dental crowns are a common and highly effective solution for restoring damaged or decayed teeth. They provide both cosmetic and functional benefits, improving the strength, appearance, and longevity of a tooth. If you're considering a dental crowns Brookline, or have recently had one placed, you may be wondering how long dental crowns last and what factors influence their lifespan. This article will explore the average lifespan of dental crowns, the types of crowns available, and how to maintain them to maximize their longevity.
What Are Dental Crowns?
Dental crowns are custom-made caps placed over a damaged or weakened tooth to restore its shape, size, strength, and appearance. Crowns are typically used for teeth that are severely decayed, fractured, or weakened after a root canal procedure. They can also be used to improve the aesthetic appearance of discolored or misshapen teeth.
The process of getting a dental crown involves reshaping the affected tooth to accommodate the crown, taking an impression of the tooth, and placing a temporary crown while the permanent one is being made. Once the permanent crown is ready, it is cemented onto the prepared tooth.
How Long Do Dental Crowns Last?
The lifespan of a dental crown can vary based on several factors. On average, dental crowns last anywhere from 5 to 15 years, but with proper care, some crowns can last even longer. Factors that influence the longevity of dental crowns include the material used, the location of the crown in the mouth, and the patient’s dental habits.
Types of Dental Crowns and Their Durability
Different types of dental crowns offer varying levels of durability. The choice of material can affect both the longevity and aesthetic appearance of the crown. Here’s a breakdown of the most common types of dental crowns and their expected lifespan:
1. Porcelain Crowns
Porcelain crowns are popular for their natural, tooth-like appearance. These crowns are ideal for visible teeth, such as those in the front of the mouth. Porcelain is durable but can be more prone to chipping or cracking under excessive pressure compared to other materials.
- Lifespan: 10 to 15 years.
- Best For: Front teeth, where aesthetics are a priority.
2. Porcelain-Fused-to-Metal (PFM) Crowns
PFM crowns offer a combination of durability and aesthetics. The metal base provides strength, while the porcelain exterior mimics the look of natural teeth. However, PFM crowns can sometimes show a metal line at the gum line, especially if the gum recedes over time.
- Lifespan: 10 to 15 years.
- Best For: Teeth that require more strength, such as molars, while still maintaining a natural appearance.
3. Metal Crowns (Gold or Other Alloys)
Metal crowns are incredibly durable and resistant to wear. They are typically used for back teeth, where the aesthetic appearance is less of a concern. Metal crowns are less likely to chip or crack, making them ideal for patients who grind their teeth.
- Lifespan: 15 to 20 years or more.
- Best For: Molars or teeth that are less visible.
4. Zirconia Crowns
Zirconia crowns are a newer type of crown that offers both strength and aesthetic appeal. Made from a durable ceramic material, zirconia crowns are often used as an alternative to PFM crowns, providing excellent longevity and a natural look.
- Lifespan: 10 to 20 years.
- Best For: Any tooth, especially those that require both durability and aesthetics.
Factors That Affect the Longevity of Dental Crowns
While the material of the crown plays a significant role in its lifespan, other factors can influence how long a dental crown lasts. Understanding these factors can help you take proactive steps to maintain your crowns and extend their life.
1. Oral Hygiene
Good oral hygiene is essential for maintaining the health of both your natural teeth and dental crowns. Plaque buildup around the crown can lead to decay or gum disease, which can compromise the bond between the crown and the tooth underneath.
- Tips for Good Oral Hygiene: Brush twice a day with fluoride toothpaste, floss daily, and use an antimicrobial mouthwash to reduce plaque buildup.
2. Bite and Jaw Alignment
If you have a misaligned bite or suffer from bruxism (teeth grinding), it can put excessive pressure on your crowns and cause them to wear down or break. Crowns placed on teeth that are under heavy pressure, such as molars, are more likely to experience damage over time.
- Solution: If you grind your teeth, consider wearing a night guard to protect your crowns while sleeping.
3. Dietary Habits
Certain foods and beverages can contribute to the wear and tear of dental crowns. Sticky foods, like caramel and taffy, can pull at the crown, while hard foods, such as nuts or ice, can crack or chip the crown. Additionally, highly acidic foods and drinks (like soda and citrus) can wear down the crown’s surface over time.
- Solution: Avoid biting down on hard objects, and be cautious when eating sticky or sugary foods. Regularly clean your crowns to prevent plaque buildup from acidic foods.
4. Accidental Damage
Accidents can happen, and sometimes crowns can chip or break due to trauma, such as biting down on something too hard or being involved in an accident. Porcelain crowns, in particular, can be more susceptible to damage from trauma than metal crowns.
- Solution: If you participate in contact sports or activities that put your mouth at risk, consider wearing a mouthguard to protect your crowns and natural teeth.
5. Age and Wear Over Time
Like any dental restoration, crowns can wear down gradually over time. Even the strongest materials will eventually show signs of wear and tear. The color of porcelain crowns may also fade or discolor, especially if exposed to staining substances over the years.
- Solution: Regular check-ups with your dentist can help detect any signs of wear or damage to your crowns early, allowing for prompt repairs or replacements if necessary.
How to Maximize the Lifespan of Your Dental Crowns
Taking good care of your dental crowns can help ensure they last as long as possible. Here are some additional tips to maximize the longevity of your crowns:
1. Regular Dental Check-ups
Visiting your dentist regularly for check-ups is essential for ensuring the longevity of your dental crowns. During these visits, your dentist can check for any signs of damage, decay around the crown, or changes in your bite that could affect the crown.
2. Avoid Using Teeth as Tools
Using your teeth to open packages, bottles, or bite through hard objects can damage your crowns. Avoid using your teeth as tools, and always use proper implements to open or cut things.
3. Quit Smoking
Smoking can stain your dental crowns and lead to gum disease, which can affect the health of your crown and the tooth underneath. Quitting smoking is not only good for your overall health but also helps preserve the appearance and function of your dental crowns.
4. Address Any Teeth Grinding Issues
If you grind your teeth at night, it is important to wear a night guard to protect your crowns from excessive pressure. Your dentist can help create a custom night guard that will protect your crowns and your natural teeth.
When Should You Replace a Dental Crown?
Over time, even the best-maintained dental crowns may need to be replaced. Signs that your crown may need replacing include:
- Visible Damage: Cracks, chips, or visible wear on the crown.
- Pain or Sensitivity: If you experience pain or sensitivity around the crown, it could indicate that the tooth underneath is damaged or that the crown has become loose.
- Discoloration: If your porcelain crown has become discolored or stained beyond cleaning, it may need replacing.
If you notice any of these signs, it’s important to consult with your dentist to determine if the crown needs to be replaced or repaired.
Conclusion
Dental crowns are a highly effective way to restore damaged or decayed teeth, and with proper care, they can last many years. The lifespan of your crown depends on factors like the material used, oral hygiene, dietary habits, and any underlying dental issues. By following good oral care practices and working closely with your dentist, you can maximize the longevity of your crowns and ensure they continue to function effectively.
