Have you been told to get a porcelain crown to restore your damaged and diseased tooth at the dental office in Show Low? Do you need more clarification about their durability and longevity? Then we have answers to all your queries. Porcelain crowns are a popular choice for dental restorations due to their natural appearance and durability. However, like any other dental appliance, they have a limited lifespan. In this article, we will explore the average lifespan of porcelain crowns, the factors that affect their durability, and the signs that indicate they need to be replaced.

What is a porcelain crown?

A porcelain crown is a tooth-colored shell, or encasing that covers your tooth completely. These aesthetic shells help repair a damaged, diseased, or broken tooth to restore its oral form, function, and aesthetics. 

These are custom-made according to the size, shape, and shade of your natural teeth for improved strength, resilience, and aesthetics. 

What is the purpose of a crown?

Your dentist may recommend a crown to:

• Restore a broken or cracked tooth
• Protect a weak tooth from breaking 
• Attach dental bridges 
• Act as a permanent restoration for dental implants 
• Protect a fragile tooth following a root canal 

What is the average lifespan of porcelain crowns? 

According to several research studies, on average, porcelain crowns are supposed to last between 5 to 15 years. However, with proper care and maintenance, they can last up to 25 years or more. The lifespan of porcelain crowns depends on various factors, including the quality of the material, oral hygiene practices, biting forces, diet, and regular dental checkups.

What factors affect the lifespan of porcelain crowns? 

Several factors can influence the lifespan of porcelain crowns, including:

Material quality: High-quality porcelain materials offer better durability and longevity.

Oral hygiene practices: Regular brushing, flossing, and rinsing with an antibacterial mouthwash help prevent plaque buildup and gum disease, which can compromise the integrity of the crown.

The dentist’s skill: The way the dentist uses their skill to prepare the tooth, and take oral impressions can greatly make a difference in the life of the crown.

Biting forces: Excessive grinding or clenching of teeth can reduce the lifespan of porcelain crowns.

Diet: Consuming sticky or acidic foods and beverages can lead to the deterioration of the crown material over time.

Regular dental checkups: Regular dental checkups can help identify issues early on, and necessary interventions can be provided to prevent further damage.

Health of the affected tooth: If the tooth is healthy with longer roots and healthier surrounding gum and bone levels, both the crown and the tooth are likely to have a better prognosis. 

What are the signs that indicate your porcelain crowns need to be replaced? 

While porcelain crowns can last for many years, they may eventually need to be replaced. The following signs indicate that your porcelain crowns need to be replaced:

• Pain involving the tooth with the crown, especially while chewing
• A feeling that the crown is unstable or appears to be moving or loose 
• The tooth with the crown is no longer aesthetically pleasing due to discoloration 
• Chipping or cracking of the crown
• Decay underneath the crown

Porcelain crowns are a durable and aesthetically pleasing option for dental restorations. However, their lifespan depends on various factors, including material quality, oral hygiene practices, biting forces, diet, and regular dental checkups. By following good oral hygiene practices, being mindful of your eating habits, and regularly visiting your dentist, you can enjoy the benefits of porcelain crowns for an extended period. If you experience any signs that indicate your porcelain crowns need to be replaced, consult with your dentist to determine the best course of action.
