How Long Do White Dental Crowns Last?

White dental crowns are a restorative dental solution that protect and enhance the appearance of damaged or decayed teeth. Unlike metal crowns, white dental crowns blend seamlessly with natural teeth. Continue reading to learn more about how long these crowns last so you can be prepared for potential replacements in the future.

Factors Affecting the Longevity of White Dental Crowns

The lifespan of white dental crowns depends on several key factors such as:

Material Used

Porcelain: Porcelain crowns are highly aesthetic and closely resemble natural teeth. However, they are more prone to chipping and may need replacement sooner than other materials.

Zirconia: Zirconia crowns are known for their strength and durability. They can withstand strong bite forces and typically last longer than porcelain.

Ceramic: Ceramic crowns offer a balance of aesthetics and strength. They are a good alternative if you want durability without the opacity of zirconia.

Oral Hygiene Practices

Brushing and Flossing Habits: Proper daily oral hygiene, including brushing twice a day and flossing, helps prevent plaque buildup that can weaken the crown’s bond to the tooth.

Use of Non-Abrasive Toothpaste: Some toothpaste formulas contain harsh abrasives that can wear down the surface of the crown, shortening its lifespan.

Dietary Habits

Impact of Acidic and Hard Foods: Consuming acidic foods like citrus and vinegar can erode tooth enamel and weaken dental cement. Biting down on hard foods, such as nuts and ice, can cause fractures in the crown.

Staining Foods and Beverages: Drinks like coffee, tea, and red wine can discolor white dental crowns over time, affecting their appearance.

Bite Force and Teeth Grinding (Bruxism)

Effects of Excessive Pressure on Crowns: Bruxism puts excess pressure on dental crowns, leading to premature wear and potential fractures.

Use of Night Guards for Protection: Wearing a night guard can help protect crowns from the effects of grinding and clenching during sleep.

Quality of Dental Work and Placement

Importance of Skilled Dental Professionals: The expertise of the dentist placing the crown plays a significant role in its longevity. Poorly fitted crowns can loosen over time and may require replacement sooner.

Proper Fitting and Bonding: Ensuring that the crown is securely bonded and properly aligned with the natural bite prevents complications and extends its lifespan.

Average Lifespan of White Dental Crowns

The lifespan of white dental crowns varies depending on the material and your habits:

• Porcelain crowns typically last between 10 to 15 years with proper care.
• Zirconia crowns can last 15 to 20 years or more due to their superior strength.
• Ceramic crowns usually last around 10 to 15 years before needing replacement.

Compared to metal and gold crowns, white dental crowns may not last as long but offer a more natural appearance. 

How to Extend the Lifespan of White Dental Crowns

To maximize the longevity of white dental crowns, consider the following care tips:

Regular Dental Check-ups and Cleanings

Routine dental visits help detect early signs of wear, allowing for timely intervention and prolonging the crown’s lifespan.

Avoiding Harmful Habits

Refrain from chewing on hard objects like ice, pencils, and hard candies, as these can damage the crown.

Proper At-Home Oral Care Routine

Use a soft-bristled toothbrush and fluoride toothpaste to keep both natural teeth and crowns in good condition. Flossing daily also prevents plaque buildup around the crown edges.

When to Replace a White Dental Crown

Although white dental crowns are durable, they do not last forever. Here are signs that indicate a replacement may be needed:

Cracks, Chips, or Visible Wear: porcelain or ceramic crowns can develop small fractures over time.

Discoloration or Changes in Appearance: surface stains from coffee, wine, tea, and smoking can accumulate. Crowns don’t respond to whitening treatments, so they will need to be replaced if it is severely discolored.

Loose or Ill-Fitting Crowns: an unstable crown occurs when the bonding cement becomes weakened. 

Discomfort or Sensitivity Around the Crown: persistent pain or tooth sensitivity can be indicative that a crown is no longer fitting properly. 

Gum Recession Around the Crown: the margin of the dental crown can become exposed over time, increasing the risk of tooth decay.

Recurrent Decay or Infection: bacteria can get in if you don’t maintain your oral hygiene habits or if the bonding material weakens.

With proper care, most white dental crowns can last anywhere from 10 to 20 years. Regular dental visits are crucial for monitoring the condition of crowns and addressing potential issues early.
