Getting a dental crown is a big investment in both money and your smile. The good news? With the right care, a dental crown can last 15, 20, or even 30 years. The bad news? Many people unknowingly do things every day that shorten their crown’s life without realising it.
In this guide, you will find simple, dentist-approved tips to help your dental crown last as long as possible, no complicated routines, just practical habits that really work.
What Is a Dental Crown and Why Does Longevity Matter?
A dental crown is a tooth-shaped cap that fits over a damaged or weakened tooth to restore its shape, size, strength, and appearance. Learn more about what a dental crown is and how it works on our dedicated page.
Crowns are used for many reasons:
- To protect a tooth after a root canal
- To cover a cracked or broken tooth
- To restore a severely decayed tooth
- To anchor a dental bridge
- To improve the look of a misshapen or discoloured tooth
A dental crown is not a one-time fix. It needs care just like your natural teeth. And because replacing a crown can cost hundreds to thousands of dollars, making it last longer saves you a lot of money and time in the dentist’s chair.
| Quick Fact
Most dental crowns last 10–15 years on average. But with proper care? Many patients keep theirs for 20–30 years. Your daily habits make the biggest difference. |
How Long Does a Dental Crown Last? (By Material)
The material your crown is made from plays a big role in how long it will last. Here is a quick comparison:
| Crown Material | Average Lifespan | Key Advantage |
| Gold / Metal | 20–30+ years | Highest durability |
| Zirconia | 15–20+ years | Best balance of strength & looks |
| Porcelain-Fused-to-Metal (PFM) | 10–15 years | Good strength, natural look |
| All-Ceramic / All-Porcelain | 10–15 years | Best aesthetics, front teeth |
| Composite Resin | 5–8 years | Budget option, shorter life |

10 Care Tips to Make Your Dental Crown Last 15+ Years
Tip 1: Brush Twice a Day The Right Way
Brushing is not just for your natural teeth. The tooth under your crown can still decay. Use a soft-bristle toothbrush and fluoride toothpaste. Brush at the gumline where the crown meets your tooth. This area is especially vulnerable to plaque build-up. Brush for at least two minutes, twice a day, every day.
Avoid hard-bristle brushes and abrasive whitening toothpastes; these can scratch porcelain crowns and weaken the surface over time.
Tip 2: Floss Around Your Crown Daily
Flossing is one of the most important and most skipped steps in crown care. Food and bacteria build up at the edges of the crown where it meets your gum. If you do not floss, decay can form under the crown, causing it to fail early.
Use gentle C-shaped flossing motions rather than snapping the floss up and down. You can also use a water flosser or interdental brush for easier cleaning around the crown margins.
Tip 3: Avoid Chewing Hard and Sticky Foods
Your crown is strong, but it is not indestructible. Biting on hard things puts enormous pressure on the crown and can cause it to crack, chip, or loosen. Avoid:
- Ice cubes
- Hard-boiled sweets and lollipops
- Crunchy nuts or popcorn kernels
- Sticky toffees, caramel, or chewy sweets
- Hard bread crusts or bagels
Sticky foods are especially dangerous because they can pull the crown loose from the tooth underneath.
Tip 4: Wear a Night Guard If You Grind Your Teeth
Teeth grinding (called bruxism) is one of the top reasons dental crowns fail early. If you grind or clench your teeth at night, the repeated pressure can crack or wear down even the strongest crown.
Many people grind their teeth without knowing it. Signs include a sore jaw in the morning, headaches, or a partner telling you they hear grinding at night. Talk to your dentist about a custom night guard. It is a simple protective device you wear while you sleep that takes the pressure off your crown.
Tip 5: Do Not Use Your Teeth as a Tool
Using your teeth to open packaging, bite nails, tear tape, or crack nuts puts sudden, uneven pressure on your crown. This is a common cause of chipping and cracking. Get a pair of scissors, and your crown will thank you.
Tip 6: Attend Regular Dental Check-Ups
Visit your dentist every 6 months for a check-up and professional cleaning. During these visits, your dentist will:
- Check the crown’s fit and integrity
- Look for early signs of decay at the crown margin
- Assess your bite alignment to ensure the crown is not under extra stress
- Clean areas that your toothbrush cannot reach

Tip 7: Cut Down on Sugary and Acidic Foods
Even though the crown itself cannot decay, the natural tooth structure underneath it can. Sugar feeds the bacteria that cause decay. Acidic foods and drinks (like fizzy drinks, citrus juice, and vinegar) can weaken the cement that holds the crown in place over time.
Try to limit sugary snacks between meals, rinse your mouth with water after acidic drinks, and wait 30 minutes before brushing after eating acidic foods.
Tip 8: Use Fluoride Mouthwash
Adding a fluoride mouthwash to your routine gives your natural tooth structure extra protection underneath the crown. It also helps keep the surrounding gum tissue healthy, which is essential for crown stability. Use it once a day after brushing.
Tip 9: Address Bite Problems Early
If your crown feels too high or uneven when you bite down, do not wait; call your dentist. An uneven bite puts extra stress on the crown every time you eat or speak. Over time, this leads to faster wear and potential cracking. This is a quick, easy fix when caught early.
Tip 10: Choose an Experienced Dentist for Crown Placement
The quality of crown placement matters as much as your aftercare. A well-fitted crown with sealed margins is far less likely to develop decay or come loose than one that was not placed precisely. At Essentials Dental, we use

Warning Signs Your Crown May Need Replacing
Even with great care, crowns do not last forever. Watch out for these signs that your crown might need attention:
- Sensitivity or pain when biting down
- A dark line at the gumline (common with older PFM crowns)
- The crown feels loose or wobbly
- Visible cracks, chips, or rough edges
- Persistent tooth sensitivity to hot or cold
- Swelling or tenderness in the gum around the crown
If you notice any of these, do not wait. Early action can save your crown and the tooth underneath it.

Frequently Asked Questions (FAQs)
Q: How long should a dental crown last?
Most dental crowns last between 10 and 15 years on average. However, with excellent daily care, many crowns last 20 to 30 years. Gold and zirconia crowns tend to have the longest lifespans.
Q: Can a dental crown last a lifetime?
In some cases, yes, particularly gold crowns in patients with excellent oral hygiene and no grinding habits. While it is rare for most crown types, 30+ year lifespans are possible with the right care.
Q: Can decay form under a dental crown?
Yes. The crown itself cannot decay, but the natural tooth structure underneath it can. This is called secondary caries or recurrent decay. Regular brushing, flossing, and dental check-ups are essential to prevent this.
Q: What foods should I avoid with a dental crown?
Avoid hard foods like ice, boiled sweets, and popcorn kernels. Also, avoid sticky foods like toffee, caramel, and chewing gum, as these can pull the crown loose over time.
Q: Does grinding your teeth damage dental crowns?
Yes. Teeth grinding (bruxism) is one of the most common causes of premature crown failure. A custom night guard from your dentist will protect your crown while you sleep.
Q: How do I know if my crown needs to be replaced?
Signs include pain or sensitivity when biting, a loose or wobbly feeling, visible cracks, a dark line at the gumline, or persistent gum swelling near the crown. Contact your dentist if you notice any of these.
Q: Can I whiten my dental crown?
No. Dental crowns do not respond to whitening treatments. If you want to whiten your teeth, do so before getting a crown so your dentist can match the crown shade to your whitened teeth.
Q: Is it normal for a crown to feel sensitive after placement?
Some mild sensitivity in the first few weeks after a new crown is placed is normal. However, if sensitivity is severe or lasts more than a few weeks, contact your dentist for a check.
Conclusion
A dental crown is one of the best investments you can make for your oral health, but only if you look after it properly. The good news is that making your crown last 15, 20, or even 30 years does not require anything complicated. It comes down to consistent daily habits: brush well, floss every day, avoid hard and sticky foods, wear a night guard if you grind, and see your dentist regularly.
The most important thing you can do right now is book a check-up if it has been more than 6 months since your last visit. Regular professional care is the single biggest factor in extending your crown’s life.
