How Long Does a Dental Crown Last?
Dental crowns offer reliable support for teeth that have lost strength or structure. But how long do they really last? If you’re wondering whether your crown will stand the test of time, you’re not alone. This blog breaks down what impacts crown durability—and how simple habits can help you get the most from your investment.
Average Lifespan of a Dental Crown
On average, a dental crown lasts between 10 and 15 years. Some patients report keeping theirs even longer—20 years isn’t unheard of with proper care. But every mouth is different, and the life of your crown depends on your habits, your bite, and even the material used. If you’re considering or already have dental crowns in St. Petersburg, FL, knowing how long they typically last helps you plan ahead and take better care of them.
Here’s a general guideline by crown material:
- Porcelain crowns: 10–15 years
- Metal crowns: 15–20 years
- Porcelain-fused-to-metal (PFM): 10–15 years
- Zirconia crowns: 15+ years
With regular checkups, even older crowns can keep doing their job.
Factors That Influence Crown Longevity
Several elements come into play when it comes to how long your crown will last. Some are within your control, while others depend on your dental history.
- Material Used
Some materials handle pressure better. Metal crowns tend to last longer, while porcelain crowns offer a more natural look but may chip over time. - Oral Hygiene Habits
Brushing, flossing, and professional cleanings keep decay and gum issues away. That means fewer chances of problems under or around your crown. - Bite and Grinding Habits
Do you clench or grind your teeth, especially at night? Over time, that force wears down your crown. A night guard can help reduce this risk. - Location of the Crown
Back teeth take more pressure when you chew. Crowns on molars wear out quicker than those on front teeth. - Skill of the Dentist
A well-fitted crown lasts longer. That’s why choosing an experienced dentist near you is crucial.
Signs Your Dental Crown May Need Replacement
Crowns aren’t forever. At some point, you may notice changes that signal it’s time for a replacement. Dentists in St. Petersburg can identify issues early and recommend the right time for a new crown to prevent further complications.
Watch for:
- Pain or sensitivity near the crown
- A visible crack or chip
- The crown feels loose
- Discoloration around the gumline
- Receding gums exposing the crown edge
- Food is getting stuck around the crown
Don’t ignore these signs. Early attention prevents bigger issues.
How to Make Your Dental Crown Last Longer
Want your crown to stick around for the long haul? Here’s how to protect it:
- Brush twice daily with a soft-bristled toothbrush.
- Floss daily, especially around the crown’s edges
- Avoid sticky or hard foods that can pull or crack the crown
- Wear a personalized night guard if you grind your teeth
- Don’t use your teeth as tools—opening packages or biting your nails can weaken the crown
- See your local dentist every 6 months for cleanings and exams
Patients who follow these steps often enjoy their crowns well past the 15-year mark.
Do Dental Crowns Ever Fail Early?
Yes, though it’s rare. Early failure usually points to one of the following causes:
- Poor fit or placement
- Improper bite alignment
- A weak natural tooth underneath
- Sudden trauma (like a fall or impact)
- Decay forming at the crown’s edge
If a crown falls out or cracks within a short time, your dentist can usually fix or replace it. At Flash Dentspa, we take time to make sure your crowns fit right from the start.
Dental Crown Replacement: What to Expect
If you’ve had your crown for over a decade or you’re experiencing discomfort, it might be time for a new one. Here’s what usually happens during a crown replacement:
Step 1: Evaluation
Your dentist will check the crown and tooth underneath for signs of damage or decay.
Step 2: Removal
The old crown is taken off gently. Sometimes, minor drilling is needed to loosen it.
Step 3: Preparation
Your tooth is cleaned and shaped again. If there’s decay, it gets treated first.
Step 4: New Impression
A mold or scan of your tooth is taken to ensure your new crown fits perfectly.
Step 5: Temporary Crown
Your tooth stays protected with a temporary crown during fabrication.
Step 6: Final Placement
The crown is fitted and adjusted for comfort.
You’ll walk out with a crown that looks good, feels natural, and works like a real tooth.
