Dental crowns are invaluable restorations used to strengthen and protect damaged or weakened teeth, while also enhancing their appearance. While dental crowns are designed to be durable, they are not meant to last a lifetime. Understanding the lifespan of a dental crown and knowing when to replace it is essential to maintain optimal oral health. In this blog post, we will explore factors affecting the longevity of dental crowns and how often they should be replaced for optimal dental care.

The Lifespan of Dental Crowns:

The lifespan of a dental crown can vary depending on several factors, such as the material used, oral hygiene practices, and the individual’s oral habits. On average, dental crowns can last anywhere from 10 to 15 years or even longer with proper care. However, it’s important to note that each case is unique, and some crowns may require replacement sooner or later based on specific circumstances.

  • Factors Affecting Dental Crown Longevity:

a. Material: The material of the dental crown plays a significant role in its durability. Crowns made from high-quality materials like porcelain fused to metal (PFM), all-ceramic, or zirconia tend to offer better longevity compared to older metal-based crowns.

b. Oral Hygiene: Good oral hygiene practices, including regular brushing, flossing, and routine dental check-ups, are essential for prolonging the life of a dental crown. Poor oral hygiene can lead to decay or gum disease around the crown, compromising its integrity.

c. Bruxism or Teeth Grinding: Individuals who grind or clench their teeth (bruxism) are at higher risk of damaging their dental crowns. Nightguards or splints may be recommended to protect the crowns and prevent premature wear.

d. Diet: A diet high in sugary and acidic foods can increase the risk of tooth decay around the crown’s edges, necessitating early replacement. Limiting the consumption of such foods can help preserve the crown’s lifespan.

e. Bite Alignment: An uneven or misaligned bite can put excess pressure on certain teeth, including dental crowns, leading to premature wear or cracking.

  • Signs That a Dental Crown Needs Replacement:

While the average lifespan of dental crowns  is around 10 to 15 years, specific signs indicate when a crown may need replacement:

  • Visible Wear and Tear: Cracks, chips, or visible wear on the crown’s surface indicate that it may need replacement.
  • Recurring Decay: If decay develops around the crown’s edges or beneath it, a replacement may be necessary.
  • Discomfort or Sensitivity: Persistent discomfort or sensitivity around the crown could be a sign of an issue that requires attention.
  • Poor Fit: If the crown becomes loose or no longer fits properly, it may need to be replaced to ensure optimal function.


Dental crowns are valuable dental restorations that can last for many years with proper care. While the average lifespan of a crown is 10 to 15 years, it’s essential to monitor its condition regularly and be attentive to signs of wear, discomfort, or decay. By maintaining good oral hygiene, addressing bruxism, and scheduling regular dental check-ups, you can extend the longevity of your dental crown and enjoy its benefits for many years. If you notice any issues with your dental crown, consult with your Plano dentists promptly to determine the best course of action for maintaining a healthy and beautiful smile.
