Even the best and most durable solutions have their limits.
Dental crowns are designed to be strong, functional, and long-lasting. However, like natural teeth, they’re not indestructible. Crowns can experience wear and tear with extended normal use, with certain habits and dietary choices also potentially affecting their longevity. So, the more appropriate question here might be, "How quickly do dental crowns weaken over time?" The answer? It depends on how well you take care of them.
Let’s explore the key factors that impact dental crown durability and how to maximize their longevity.
Natural Wear and Tear on Dental Crowns
Dental crowns endure daily chewing, grinding, and temperature changes like natural teeth. Although high-quality materials like porcelain and zirconia are designed to withstand pressure, crowns can gradually wear down, particularly after 10+ years. Bear in mind that if a crown becomes thin or loose—however long you’ve had it—it will require repair or replacement.
How Diet and Habits Affect Crown Strength
What you eat and how you use your teeth directly impact dental crown longevity. Biting on hard foods like ice, nuts, hard candy, or (accidentally) olive pits can lead to cracks or chips. Teeth grinding (bruxism) also puts excess pressure on crowns, making them more susceptible to damage. Additionally, consuming acidic foods and sugary drinks—coffee and citrus fruits, for instance—can weaken the bonding that holds the crown in place.
Maintenance Tips for Long-Lasting Crowns
Want your crown to last? Good oral hygiene is essential. Brushing and flossing daily, avoiding excessive force when chewing, and keeping up with regular dental checkups can help prevent premature wear. If you grind your teeth, a nightguard can protect your crown from damage while you sleep.
Keep Your Crown Strong and Healthy!
Whether you have a dental crown in need of treatment or are considering getting one, proper care is essential for longevity. However, even the best-maintained crowns require re-treatment or replacement at some point.
