Dental crowns are essential for restoring strength, function, and appearance to damaged teeth. But just like natural teeth, crowns have a lifespan. Over time, everyday wear and tear, oral changes, or unnoticed decay can compromise your crown’s effectiveness.
So, when is it time to replace an old dental crown?
Let us explore the most common signs, causes of crown failure, and the benefits of timely replacement—because protecting your crown is key to protecting your smile.
How Long Do Dental Crowns Last?
On average, dental crowns last between 10 to 15 years. With excellent oral hygiene and regular dental visits, some crowns may last even longer. However, lifestyle habits, grinding, or changes in gum and bone structure can shorten their lifespan.
Key factors affecting crown longevity include:
- Type of material used (e.g., porcelain, zirconia, metal)
- Oral hygiene and gum health
- Bruxism (teeth grinding or clenching)
- The fit and placement quality
- Regular dental check-ups and maintenance
When to Replace an Old Dental Crown?
Crowns are durable and reliable, but they aren’t immune to failure. Knowing the signs that your dental crown may need to be replaced is critical to maintaining long-term oral health. Ignoring these signs can lead to pain, infection, or the loss of the underlying tooth. If you notice any of the following issues, it may be time to schedule a dental evaluation.
1. Tooth or Gum Pain Around the Crown
Ongoing pain, sensitivity, or swelling around the crowned tooth may indicate decay underneath or deterioration of the crown seal. Pain while biting or consuming hot and cold foods often signals a deeper issue that needs evaluation.
2. Fractured or Damaged Crown
Crowns may crack or chip over time due to chewing hard foods, teeth grinding, or trauma. While minor chips can be repaired, severe fractures weaken the crown’s ability to protect your tooth and require full replacement.
3. Loose or Wobbly Crown
If your crown feels loose, it could mean the bonding cement is wearing out. A loose crown can trap food and bacteria, putting the tooth at risk for decay. It should be checked and replaced if necessary.
4. Discoloration or Dark Line at the Gum Line
A dark line or shadow near the gum line may occur if you have a porcelain-fused-to-metal crown or if the underlying tooth is decaying. This affects both function and aesthetics and can be a sign that it’s time for a new crown.
5. Change in Smile Aesthetics
Over time, older crowns may not match your natural teeth due to wear or changes in surrounding teeth. You may also notice metal edges becoming visible, especially in older crown types. Newer crown materials offer improved durability and a more natural appearance.
Why Do Dental Crowns Fail?
Crowns may fail over time due to several reasons, including:
- Decay beneath the crown caused by poor seal or hygiene
- Trauma or excessive biting force
- Gum recession exposing tooth margins
- Bruxism without protective mouthguards
- Aging materials or poorly fitted crowns
Replacing old crowns at the right time prevents complications and ensures continued protection for the underlying tooth.
