Dental crowns are a trusted solution for restoring the shape, strength and appearance of damaged teeth. Whether you’ve recently had a crown fitted or have had one for several years, it is completely natural to wonder how long it will last. In this blog post, we’ll explore the lifespan of dental crowns, what factors affect their durability and how to make sure yours lasts as long as possible.
Average Lifespan of a Dental Crown
On average, a dental crown will last between 10 to 15 years. However, this is not a fixed rule. With excellent oral hygiene and regular dental check-ups, many crowns last upwards of 20 years. In some cases, they can last even longer, especially if the crown is made from high-quality materials and the underlying tooth structure remains healthy.
What Impacts the Longevity of a Crown?
The longevity of a crown can vary significantly based on a number of factors. Firstly, the material used plays a crucial role. Crowns made from metal alloys, such as gold or platinum, tend to last longer than ceramic or porcelain options, although the latter are often chosen for their natural appearance.
Secondly, the location of the crowned tooth matters. Crowns on molars, which handle most of the chewing force, are more prone to wear and tear compared to crowns on front teeth. Additionally, the skill of the dentist, the condition of the natural tooth beneath the crown and the quality of the fit can all influence how long a crown remains functional.
Understanding Crown Materials and Their Longevity
Different materials offer varying benefits and expected lifespans. Metal crowns, especially those made from gold alloys, are known for their strength and longevity. These are less likely to crack or chip, making them ideal for back teeth where chewing forces are strongest.
Porcelain-fused-to-metal (PFM) crowns offer a balance between durability and aesthetics, making them a popular choice for both front and back teeth. However, they can sometimes develop a dark line at the gum edge over time, especially if gums recede.
All-ceramic or all-porcelain crowns are the most visually pleasing option and are often used on front teeth for a natural look. While they offer good strength, they may be more prone to chipping under excessive pressure compared to metal-based crowns.
Zirconia crowns, a newer and increasingly popular option, combine aesthetics with strength. They are less likely to wear down and are particularly resistant to cracking, making them suitable for various positions in the mouth.
The Impact of Crown Position in the Mouth
Where your crown is located plays a significant role in how long it will last, and how easy it is to put back if it falls off. Crowns on molars and premolars experience the most stress due to grinding and chewing, which can lead to quicker deterioration if not properly maintained.
By contrast, crowns placed on front teeth, incisors and canines, are under less mechanical pressure. These crowns generally last longer due to the reduced load, provided they are not exposed to trauma or bad habits like nail-biting or opening packages with teeth.
Understanding the function and position of your crowned tooth can help you take specific steps to preserve its condition and extend its lifespan.
How to Help Your Crown Last Longer
Your daily oral habits have a direct impact on the lifespan of your crown. Habits such as grinding your teeth (bruxism), chewing ice, biting fingernails or using your teeth as tools can all lead to premature damage. If you grind your teeth, your dentist may recommend a night guard to protect both your crown and your natural teeth.
Furthermore, maintaining good oral hygiene is essential. Brushing twice a day with fluoride toothpaste, flossing daily and attending routine dental visits can help prevent decay around the crowned tooth and protect your gum health, both of which are crucial for prolonging the life of your crown.
Signs Your Crown May Need Replacing
While crowns are durable, they are not indestructible. Over time, they may become loose, chipped or worn. You may also notice increased sensitivity or discomfort around the crowned tooth. These could be early signs that your crown is reaching the end of its lifespan.
It’s important to have these symptoms assessed by a dental professional promptly. In some cases, the crown can be repaired, but often, replacement is the best course of action to prevent further issues.
