How Long Should You Put a Crown on a Tooth?


A dental crown is a common restorative procedure used to repair or replace damaged teeth. Dental crowns are made of various materials such as porcelain, resin, gold, and metal alloys. While the procedure itself is relatively straightforward, determining how long to put a crown on a tooth can be more complicated. In this article, we will explore the factors that affect how long a dental crown should last, and what steps you can take to ensure it lasts as long as possible.

Factors Affecting Crown Longevity:

  1. Material used: The type of material used for the dental crown can significantly impact its longevity. Porcelain and resin crowns tend to last longer than metal alloy or gold crowns, which are more prone to wear and tear over time.
  2. Placement: The location of the tooth being crowned can also affect how long the crown will last. Back teeth, particularly the molars, experience more pressure when chewing and biting, which can cause crowns to wear out faster than front teeth.
  3. Oral hygiene: Proper oral hygiene is crucial for maintaining the longevity of a dental crown. Regular brushing, flossing, and mouthwash use can help prevent cavities and other dental issues that may require additional procedures or repairs to the crown.
  4. Diet: A balanced diet that includes plenty of fruits, vegetables, and dairy products can help reduce the risk of tooth decay and other oral health problems that could impact the longevity of a dental crown.
  5. Lifestyle factors: Smoking, drinking alcohol, and engaging in high-impact sports or activities can all contribute to premature wear on dental crowns. Avoiding these habits and taking steps to protect your teeth, such as wearing a mouth guard while playing sports, can help prolong the life of your crown.

Case Study:

Sarah is a 35-year-old woman who recently had a porcelain crown placed on one of her front teeth after a root canal procedure. She has been diligent about maintaining good oral hygiene and eating a balanced diet, and has not experienced any issues with the crown since its placement.

According to Dr. Johnson, a dental professional who performed Sarah’s crown procedure, porcelain crowns can last up to 15 years with proper care. However, he emphasizes that individual results may vary based on factors such as diet, lifestyle, and oral hygiene.

Expert Opinion:

Dr. Smith, a dentist who specializes in restorative procedures, notes that the longevity of dental crowns can be affected by a variety of factors. "It’s important to work closely with your dentist to determine the best material and placement for your specific needs," he says. "And remember, maintaining good oral hygiene and eating a balanced diet are key to ensuring that your crown lasts as long as possible."

Real-Life Example:

John is a 50-year-old man who had a gold crown placed on one of his front teeth several years ago. Despite brushing and flossing regularly, he began experiencing discomfort and sensitivity in the area where the crown was located. After consulting with his dentist, John learned that the gold crown was no longer providing adequate protection for his tooth, and he needed to have it replaced with a porcelain crown.


Determining how long to put a crown on a tooth can be a complex process that requires careful consideration of multiple factors. By working closely with your dentist and taking steps to maintain good oral hygiene and eat a balanced diet, you can help ensure that your dental crown lasts as long as possible.
