If you’ve had a dental crown placed or are about to have one placed, you’re probably wondering how long it will actually last. Crowns are known for their durability, but like anything in your mouth, they’re not invincible. While your dentist can give you a general estimate, there are several factors that influence the lifespan of a dental crown. The good news is that with proper care and a well-fitted crown, you could enjoy a strong, natural-looking tooth for years. Read on to learn more about the factors that influence the lifespan of a dental crown.
What’s the Average Lifespan of a Dental Crown?
Most dental crowns last between 10 and 30 years. The wide range in lifespan is because no two crowns or patients are the same. Some people get decades out of their crowns, while others might need a replacement sooner. If your dentist tells you your crown could last 15 years, take it as a helpful guideline rather than a guarantee.
Many dental insurance plans are willing to cover crown replacement after five to eight years. That doesn’t mean your crown will fail in that time; it just means that financially, it’s considered a long enough period for possible replacement. In truth, if your crown is well-made and properly cared for, there’s a good chance it will last far longer.
What Influences a Crown’s Longevity
The life of a crown depends on a few important variables:
- The Condition of Your Tooth: If the underlying tooth isn’t strong enough to support a crown, even the best dental work may not hold up. In cases where the tooth is too damaged or compromised, your dentist may suggest other treatments such as a dental implant or bridge.
- The Quality of the Fit: A crown that doesn’t fit right from the beginning is more likely to come loose or fall off. That’s why your dentist’s technique and the dental lab that crafts your crown play a huge role in the crown’s lifespan. A poorly made crown won’t last, no matter how careful you are.
- Oral Hygiene: Crowns cover most of the tooth, but not all of it. The exposed edges near your gumline can still decay if not cleaned properly. Brushing twice a day, flossing daily, and using mouthwash can help protect both your crown and the tooth beneath it.
- Your Habits: Chewing on ice, opening packages with your teeth, or grinding while you sleep can all shorten the lifespan of your crown. If you clench or grind your teeth at night, wearing a night guard is an easy way to protect your dental work.
- Crown Materials: Some materials last longer than others. Porcelain offers the most natural appearance but is more prone to chipping. Metal alloys and zirconia are tougher and may last longer under pressure, but don’t always offer the same visual match.
While crowns aren’t permanent, they’re one of the most reliable ways to restore damaged teeth. With the right care and maintenance, you could easily get a decade or even more out of your crown.
