To restore weak or cosmetically imperfect teeth, dentists use dental crowns. They are one of the most common and effective solutions for restorative dentistry. Whether dentists place them after a root canal or to improve the appearance of your smile, dental crowns are strong and protect your teeth.
However, many patients wonder how long their crowns are going to last. In this blog, we learn about the average lifespan of dental crowns and factors that affect the longevity of your crowns. So, let’s begin!
Average Lifespan of Dental Crowns
On average, dental crowns can last 5-15 years. However, with proper care, these crowns can last much longer. Crowns made from durable materials like metal alloys and zirconia might be able to last for 20 years or more.
The exact lifespan can vary depending on several factors, such as the materials, maintenance, and the lifestyle of a patient. Furthermore, with regular dental checkups, patients can make sure their dental crowns are in good condition over time.
Types of Dental Crowns
There are several types of dental crowns available, and each has its own lifespan. It is important to understand the different types before your treatment.
- Porcelain Crowns: These crowns are usually popular for front teeth as they closely match the natural color of teeth. However, they can last for 5-15 years since they are not metal-based.
- Porcelain-Fused-to-Metal Crowns: PFM crowns have a metal base with porcelain, and they can typically last for 10-15 years.
- Zirconia Crowns: These crowns are known for their strength and durability, and they can last for 10-20 years or longer. Their durability makes them an ideal choice for both front and back teeth.
- Gold or Metal Crowns: Metal crowns are the most durable. They can withstand chewing pressure, and they typically last for 15-30 years.
Factors That Affect How Long Dental Crowns Last
There are several factors that can influence the durability of a dental crown. Understanding these factors can help you extend the lifespan of your crowns:
Oral Hygiene:
Patients who brush daily and floss regularly can prevent decay around the crown. Also, with regular dental checkups, you can make sure your teeth and gums are in good condition, which is essential for crown longevity.
Crown Material:
The durability of a crown also depends on its material. For example, if you choose porcelain crowns, they might not last as long as metal alloys or zirconia.
Teeth Grinding:
Some patients have a habit of grinding their teeth, especially at night. The constant grinding and clenching can add extra stress on your crowns, which increases the risk of cracking.
Bite Alignment:
Having an uneven bite or excessive force can damage your crown and may also cause premature wear.
Location of the Crown:
When you get crowns on your molars, they might endure more chewing pressure and may wear faster, as compared to crowns on the front teeth.
Diet and Eating Habits:
If you consume acidic drinks and hard foods like ice, nuts, or candies, you might compromise the lifespan of your crowns.
Final Thoughts
Dental crowns are a long-lasting solution for restoring a weak or damaged tooth. While their exact lifespan can vary, on average, dental crowns can last between 5 and 15 years, or longer with proper care.
