How Long do Crowns Last? Factors Explained
Dental crowns are a popular solution for restoring damaged teeth, providing functional and aesthetic benefits. But how long do crowns last? This is a question for anyone considering this dental treatment at Salt Creek Family Dental.
The longevity of dental crowns can vary significantly based on several factors, including the materials used, oral hygiene habits, and lifestyle choices. In this article, we will explore these factors in detail and give you a clear understanding of what to expect from your dental crowns.
Factors That Impact Crown Longevity
How long do crowns last? Several factors can influence a dental crown’s lifespan. Knowing these can help you make informed decisions about dental crowns. This ensures optimal oral health and longevity of the restoration.
Crown Material
The material used for your dental crown determines its lifespan. Different materials offer varying levels of durability, aesthetics, and cost. Here are some of the most common crown materials and how long they last:
Gold Alloy
Gold alloy crowns are known for their exceptional durability and longevity. They are resistant to wear and corrosion. This makes them an excellent choice for molars where the force of chewing is the greatest.
These gold alloy crowns can last anywhere from 10 years or even longer with proper care, according to a 2015 literature review. Their downside is that they are not as aesthetically pleasing as other options, which may limit their use to less visible teeth.
Porcelain-Fused-to-Metal (PFM)
Porcelain-fused-to-metal (PFM) crowns combine the strength of metal with the natural appearance of porcelain. These crowns are more aesthetically pleasing than gold alloy crowns and offer good durability.
However, the porcelain layer can chip or crack over time, especially if you have habits like teeth grinding or nail-biting. On average, PFM crowns last between 5 to 15 years.
All-Ceramic or All-Porcelain
All ceramic or all-porcelain crowns are highly valued for their natural look, making them ideal for front teeth. While they provide excellent aesthetic results, they are not as strong as metal-based crowns and are more prone to chipping and cracking.
With proper care, all-porcelain or all-ceramic crowns can last for an average of 7.2 years to a maximum of 15 years, according to a study.
Zirconia
Zirconia crowns are known for their strength and durability, rivaling that of gold alloy crowns. They are also highly biocompatible, reducing the risk of allergic reactions. Zirconia crowns can last 10 to 15 years or more, making them a popular choice for both front and back teeth due to their durability and natural appearance.
Oral Hygiene
Your oral hygiene practices have a direct impact on how long dental crowns last. Maintaining good oral hygiene prevents decay and gum disease, which can compromise the integrity of your crowns.
Brush your teeth at least twice a day with fluoride toothpaste, floss daily, and visit your dentist regularly for check-ups and professional cleanings. Neglecting these habits can lead to the development of cavities under the crown or gum recession, both of which can reduce the lifespan of your crowns.
Lifestyle Choices
Your lifestyle choices can also influence the longevity of your dental crowns. Habits such as teeth grinding (bruxism), nail-biting, chewing ice, or using your teeth to open packages can put excessive stress on your crowns, causing them to crack or chip.
If you grind your teeth at night, consider wearing a nightguard to protect your crowns and natural teeth. Maintaining a balanced diet and avoiding excessive consumption of sugary or acidic foods can also help preserve the health of your crowned teeth and surrounding gums.
How Long Do Crowns Last: Average Lifespan of Dental Crowns
When considering how long do crowns last, understand the average lifespan of different types of crowns. On average, dental crowns can last anywhere from 5 to 15+ years. Here’s a quick summary:
Gold Alloy Crowns: 10+ years.
Porcelain-Fused-to-Metal Crowns: 5 to 15 years.
All-Ceramic or All-Porcelain Crowns: 7 to 15 years.
Zirconia Crowns: 10 to 15+ years.
Remember that these are average lifespans, and individual experiences may vary. Factors such as your oral hygiene practices, diet, and overall dental health can influence how long your crowns will last.
Do You Need to Replace Dental Crowns?
Even with the best care, dental crowns may eventually need to be replaced. Understanding the signs that indicate it's time for a replacement can help you maintain your oral health.
Decay Under a Crown
Decay under a crown is a common issue that can compromise the longevity of the restoration. This typically occurs when bacteria seep under the crown due to a poor seal or gum recession. Maintaining excellent oral hygiene and regular dental check-ups can help prevent decay and detect any issues early, ensuring your crowns last as long as possible.
Crowns That Eventually Fell
While dental crowns are designed to be durable and long-lasting, they can eventually fall off. This can happen due to a variety of reasons, such as a weakened adhesive bond, trauma, or decay under the crown.
If your crown falls off, visit a dentist as soon as possible to prevent damage to the underlying tooth and ensure proper reattachment or replacement.
