Got a tooth that’s seen better days? Maybe it’s cracked, severely decayed, or just looking a bit worse for wear? If your dentist has mentioned crowns as a solution, you’re probably wondering just how long these caps will stick around for, and if they’ll make a worthwhile difference to your smile. So, let’s dive into everything you need to know about crowns and how to make them last.
What are crowns?
A dental crown is like a custom-made helmet for your tooth. It’s a cap that covers the entire visible portion of your tooth above the gum line, essentially giving your damaged tooth a brand-new exterior. Crowns are typically made from porcelain, ceramic, metal alloys, or a combination of materials, and they’re designed to look, feel, and function just like your natural teeth.
Dentists recommend crowns for weakened, damaged, or decayed teeth, but they’re also versatile enough to cap dental implants, protect root canal-treated teeth, or anchor dental bridges. What makes them such great alternatives is their ability to completely restore both the function and appearance of your damaged tooth with a perfectly matched replacement.
What is it like to get a dental crown?
Once it’s been assessed that you need a crown, two appointments are usually scheduled to get a dental crown.
During appointment 1, the goal is to set up a strong foundation for your tooth. Your dentist will remove some of your natural enamel to make space for your new crown to stick. If you’re lacking bits of your tooth, your dentist may also use a filling material to build up certain parts of it. Next, they will take impressions, either physically with putty-like material or digitally with a handheld scanner, which will then be sent to a dental lab to craft your custom cap. Sometimes dentists will give you a temporary cap in the meantime.
Once it’s ready, your dentist will remove your temporary crown and then permanently cement the finished crown onto your prepared tooth, creating a strong, protective barrier that can handle all the chewing, grinding, and general tooth duties. Once secure, they will check the shape, colour, and fit of your new crown. To finish it off, they will bond it using dental cement.
How long does a crown last? Different types explained
Not all crowns are created the same, and the material you choose, where it’s placed in the mouth, and how well you take care of it can significantly impact longevity. In general, crowns typically last between 5 to 15 years, but some can last for 20 years or even longer.
Metal crowns
Metal crowns, including gold alloys, are the top choice as they often last 20-30 years or even longer. They’re incredibly durable but not as aesthetically pleasing.
Porcelain and metal crowns
In comparison, porcelain-fused-to-metal crowns offer a nice compromise, lasting around 15 years and providing better aesthetics compared to pure metal options
Porcelain and ceramic crowns
Porcelain and ceramic crowns typically last 10-15 years and are great for front teeth because they look incredibly natural. However, they can be a bit more prone to chipping if you’re an aggressive chewer.
Zirconia crowns
Zirconia crowns have been getting popular due to their durability, with estimates of lasting for 15-25 years, while also offering excellent aesthetics and strength.
What affects how long your crown will last?
A dental crown lifespan isn’t just about the material; it’s heavily influenced by your daily habits and oral care routine. While crowns are tough, they’re not indestructible. Let’s learn what affects the longevity of your dental crowns:
- Teeth grinding and clenching can shorten a crown’s life, so if you’re a nighttime grinder, investing in a quality night guard or splint is needed.
- Constantly crunching on ice, opening bottles with your teeth, or chewing on hard lollies can cause chips or cracks.
- While the crown itself won’t decay, the tooth underneath can still develop problems if plaque and bacteria build up around the edges.
Regular dental checkups are crucial. This is because your dentist can spot potential issues early on, like loose crowns or developing decay, before they become major problems. It’s important to stay consistent with your 6-month check-ups.
Signs your crown teeth might need replacing
Keep an eye out for warning signs that your crown is reaching the end of its life.
Pain or sensitivity around the crowned tooth could indicate decay underneath or a loose crown. If you notice the crown feels loose or wobbly, don’t wait; see your dentist immediately.
Chips or cracks in the crown material are obvious red flags, as is any discolouration around the gum line. Sometimes you might notice an unpleasant taste or smell coming from the crowned tooth, which could signal decay or infection underneath.
How to maximise your crown’s lifespan
The good news is that you have significant control over how long your crown lasts. Here’s how:
- Maintain excellent oral hygiene with regular brushing and flossing. Pay special attention to the gum line where the crown meets your natural tooth. This junction is particularly vulnerable to plaque buildup.
- Avoid using your teeth as tools. Try not to open packages or bottles with them, and be mindful of hard foods that could damage your crown.
- Treat teeth grinding. If you grind or clench your teeth, especially at night, talk to your dentist about getting a night guard or splint to preserve your teeth and enamel.
- Regular dental checkups and cleanings are non-negotiable. Your dentist can monitor your crown’s condition and catch any issues early. Don’t skip these appointments, they’re your crown’s best friend for long-term success.
