A dental crown is a durable cap that’s custom-made to fit over a tooth that’s been damaged, weakened, or cosmetically compromised. It restores the tooth’s strength, shape, and function—while also improving its appearance. At Green Line Dental Care, one of the most common questions we hear from patients is: How long do dental crowns actually last?
The truth is, crown longevity varies. It depends on things like oral hygiene, bite pressure, and ongoing dental care. But with proper maintenance, many crowns remain strong and effective for years—and often much longer than patients expect.
In this guide, we’ll break down the purpose of dental crowns, how they hold up over time, and what you can do to extend their lifespan.
What Are Dental Crowns Used For?
Crowns are one of the most effective and flexible solutions in modern dentistry. In fact, getting a crown is often a necessary final step after a root canal to protect the treated tooth from breaking. They can:
Reinforce damaged structure after trauma or large fillings
Restore cracked or broken molars
Enhance cosmetic concerns, like shape, alignment, or discoloration
Serve as support for a dental bridge
They’re also frequently used in full-mouth treatment plans or as part of urgent emergency repairs. For a complete overview, see this external guide on crowns.
When Crowns Make a Difference
Crowns are not just used reactively—they also play a major role in long-term dental planning. For patients with conditions like tooth enamel erosion, aggressive bite forces, or cosmetic misalignment, a well-placed crown can serve as both a functional and aesthetic improvement.
Whether it’s part of a full smile makeover, a veneer alternative, or a single restorative treatment, crowns are a versatile tool in modern dentistry.
How Long Do Dental Crowns Last?
Dental crowns are designed to be durable and long-lasting. With proper care and routine dental visits, many patients enjoy their crowns for many years without issue. In fact, it’s not uncommon for well-maintained crowns to remain functional far longer than expected.
A few important factors can influence how long your crown lasts:
Oral Hygiene Habits
Brushing twice a day, flossing daily, and scheduling regular teeth cleanings help prevent plaque buildup and gum disease around the crowned area. Good oral hygiene supports gum health and prevents bacteria from infiltrating crown margins.
Clenching or Grinding (Bruxism)
If you grind your teeth at night or clench your jaw during the day, you’re putting extra pressure on your crown. A nightguard may be recommended to protect both your crown and natural teeth.
Diet and Chewing Habits
Hard foods like ice, popcorn kernels, or hard candy can damage crowns. So can habits like chewing pens or fingernails. A crown is strong—but not indestructible.
Excessive wear also affects your tooth enamel, particularly if erosion or grinding is present.
Crown Placement and Bite Alignment
A properly placed crown designed to fit your bite will wear more evenly and last longer. At Green Line Dental Care, we use CEREC technology and digital smile design to ensure precision.
Materials, Software, and Technology
We don’t specify crown materials by brand, but advances in dental software and manufacturing now offer incredibly natural-looking and durable options. With our in-office CAD/CAM systems, we mill precise restorations tailored to your bite and structure.
Technologies like CBCT imaging, intraoral cameras, and digital x-rays enhance our planning and placement accuracy.
We also rely on ultrasonic scalers for gentle, thorough cleanings during follow-up visits. These innovations reduce chair time and support better long-term outcomes.

Aesthetic Benefits of Crowns
Crowns are essential in modern prosthodontics because they do more than protect teeth—they elevate aesthetics. We routinely use them to:
Improve color, shape, and contour of teeth
Enhance overall smile balance
Replace missing teeth when combined with implants or bridges
Well-designed crowns blend seamlessly with surrounding teeth and can last longer when aligned properly with your natural bite.
Signs Your Dental Crown Needs Replacement
Even the most durable crown has a lifespan. If you notice any of the following signs, book a dental exam promptly:
Pain when chewing or brushing
Discoloration around the crown margin
Fracture or visible chip
Loosening or shifting of the crown
Delaying treatment can expose the underlying structure or allow bacteria to spread beneath the restoration. In cases where infection reaches the pulp, treatment may be needed.
What If a Crown Comes Off?
Crowns can dislodge due to wear, sticky food, or trauma. If this happens:
Do not try to glue it back
Store the crown safely and bring it to your appointment
Avoid chewing on the affected side
In many cases, we can clean and recement the crown. If the crown is damaged, we’ll take impressions and prepare a new restoration.

Insurance Coverage for Crowns
We accept most dental insurance plans and provide estimates before beginning treatment. Coverage for crowns varies depending on whether the procedure is restorative or cosmetic.
Our team can help you understand your benefits and maximize them. We also offer flexible payment options for uncovered portions.
Keeping Crowns in Top Shape
Your daily routine plays a major role in longevity. Here’s what we recommend:
Brush twice daily with fluoride toothpaste
Floss carefully around the crown to remove trapped food and plaque
Use alcohol-free mouthwash to support gum health
Avoid biting hard or sticky items
Visit us for regular cleanings and exams
Ask about optional periodontal therapy if you experience gum inflammation
