If you’ve recently had a dental crown placed—or you’re considering one—you may wonder how long they last. Dental crowns are a popular restorative solution, providing strength, protection, and aesthetics to damaged teeth. But like all dental work, crowns aren’t permanent.
On average, dental crowns last between 5 and 15 years, though this varies depending on a number of factors. From the type of material used to your daily oral care routine, there’s plenty you can do to preserve their lifespan. Below, we’ll explore these factors in detail and share tips to help you get the most out of your crowns.
How Long Do Dental Crowns Last?
The lifespan of a dental crown depends on several factors, but with proper care, most last 5 to 15 years. Some crowns may even exceed 20 years if maintained in excellent condition.
Why such a broad range? Every patient is different, and key factors like lifestyle habits, oral health, and the material of the crown can all influence its longevity. Let’s take a closer look at these variables.
5 Factors That Affect the Lifespan of Dental Crowns
1. Oral Hygiene Practices
Good oral hygiene is critical for maintaining any dental restoration, including crowns. Regular brushing, flossing, and professional cleanings reduce plaque buildup and protect your crowned teeth from underlying issues like decay or gum disease.
Neglecting oral hygiene can weaken the foundation of the tooth supporting the crown, leading to premature failure. Show your crown the same care you’d give to healthy natural teeth!
2. Crown Materials
Not all crowns are created equal. The material your dental crown is made from significantly affects how long it will last. Common types include:
- Porcelain Crowns: Natural-looking but less durable, porcelain crowns are prone to chipping and general wear over time. They’re best suited for front teeth where aesthetics are a priority.
- Metal Crowns: Known for their incredible durability, metal crowns (gold or stainless steel) are highly resistant to cracking or breaking. However, they’re less appealing aesthetically.
- Porcelain-Fused-to-Metal (PFM) Crowns: A hybrid of strength and beauty, these crowns combine a porcelain exterior with a metal core. Longevity depends on proper care and avoiding excessive forces like grinding.
- Zirconia Crowns: Extremely durable and aesthetically pleasing, zirconia crowns are growing in popularity as a long-lasting, all-ceramic option.
3. Diet and Lifestyle Choices
What you eat and drink has a direct impact on crown longevity. Acidic foods, sugary drinks, and sticky snacks can damage both the crown and the underlying tooth. Similarly, chewing on hard substances (like ice or pens) can lead to cracks or chips.
Smoking and excessive alcohol consumption also contribute to gum disease, which could indirectly damage the crowned tooth’s foundation. Sticking with a balanced diet and avoiding bad oral habits can go a long way in protecting your crowns.
4. Bruxism (Teeth Grinding)
Grinding or clenching your teeth (a condition called bruxism) is a major culprit behind early crown failure. The excessive pressure wears down the material, potentially cracking or loosening the crown.
If bruxism is an issue for you, a custom-fitted night guard can provide invaluable protection. Talk to your dentist about this option—it will protect not only dental crowns but also your natural teeth.
5. Regular Dental Check-Ups
Routine dental visits are essential for monitoring the health of your crown. Your dentist will check for signs of wear, damage, or decay that could compromise its integrity. Early intervention can prevent minor issues from becoming costly problems down the line.
Annual check-ups also ensure the surrounding gums and supporting tooth remain healthy, providing a sturdy foundation for your crown.
Recognizing Crown Damage or Failure
Even with proper care, dental crowns may experience wear and tear over time. Knowing the signs of a failing crown can help you seek timely repairs or replacements.
Look out for the following:
- Visible Cracks or Chips: These may occur after trauma (like an accidental bite on something hard).
- Crown Movement: If your crown starts to feel loose or wobbly, it could mean the adhesive has worn down.
- Sensitivity or Pain: Discomfort in the crowned tooth may indicate damage, decay, or gum recession.
- Discoloration Near the Base: Dark lines or discoloration near the gumline could mean the crown’s foundation is compromised.
If you notice any of these issues, schedule a dental appointment promptly to assess the problem and find a solution.
Tips to Prolong the Lifespan of Your Dental Crowns
Looking to maximize the longevity of your dental crown? Here’s how to care for your crowns effectively for years to come:
- Brush and Floss Regularly: Use a soft-bristled toothbrush and fluoride toothpaste to clean around the crown gently. Floss to remove food particles lodged beneath the crown.
- Avoid Abrasive Toothpastes: Whitening or gritty toothpastes can wear down the crown’s surface over time.
- Protect Your Crowns During Sports: If you play contact sports, wear a mouthguard to shield your crowns (and natural teeth) from impact.
- Use a Night Guard for Bruxism: A night guard can prevent grinding damage while you sleep.
- Watch Your Diet: Minimize sugary, sticky, and hard-to-chew foods to reduce wear on the crown.
- Schedule Routine Dental Visits: Regular cleanings and check-ups are the best way to spot potential crown issues early.
