How Long Do Full Coverage Crowns Last?
If you've had a dentist recommend a full dental crown to fix and protect a damaged tooth, you're probably wondering how long you can expect it to last. Dental crowns are popular restorations used to repair damaged, weakened, or broken teeth. While crowns can significantly improve both the function and appearance of your teeth, they're not designed to last forever. Just like natural teeth, crowns can wear down over time. If you are getting a crown installed, read on to learn more about they’re lifespan and the factors that influence it.
Typical Lifespan of Dental Crowns
In general, dental crowns last between 5 and 15 years. This depends on the care they receive though. With proper care, many crowns can remain functional for over 15. There are various factors that impact the durability and longevity of dental crowns. One of the most significant factors that influence the lifespan of the crown is the material it is made from. Porcelain or ceramic crowns are common for front teeth because of their natural appearance. These types of crowns usually last about 10 to 15 years. Metal crowns, often placed on back teeth because of their strength, can last even longer, sometimes 20 years or more.
Factors That Impact the Lifespan of Crowns
Several factors can influence how long your dental crown will last, including:
- Oral Hygiene Habits: Crowns that are cared for properly last longer. Regular brushing and flossing prevent decay and gum disease around the crowned tooth. If your gums or teeth around the crown become compromised, the crown can fail sooner than expected.
- Diet and Eating Habits: What you eat can significantly affect your crown. Biting on hard or sticky foods like nuts, ice, candies can cause crowns to chip, crack, or become loose. By being mindful about eating hard foods carefully, or avoiding habits like crunching ice, you can prolong your crown’s lifespan.
- Teeth Grinding and Jaw Clenching: Grinding your teeth or clenching your jaw puts extra pressure on dental crowns. This can lead to premature wear or even damage. If you grind your teeth, your dentist may recommend a custom mouthguard. Wearing a mouthguard, especially at night, can significantly extend the life of your crowns by protecting them from unnecessary stress.
- Crown Placement in the Mouth: The location of your dental crown plays an important role in how long it lasts. Crowns on back teeth generally endure more stress due to chewing forces. As a result, they may have shorter lifespans compared to crowns placed on front teeth. Choosing durable materials like ceramic fused to metal or gold alloys for back teeth helps improve longevity.
Signs You May Need Crown Replacement
Even with excellent care, crowns eventually wear down or become damaged. If you notice sensitivity, a loose crown, or pain around your crown, it might be time for a replacement. Regular checkups allow your dentist to spot potential issues early, ensuring your crown lasts as long as possible. Ultimately, taking good care of your dental crown and regular visits to your dentist for checkups can help extend its lifespan significantly, making it a worthwhile investment in your smile.
