A dental crown is one of the most reliable investments you can make in a damaged tooth — but “how long will it last?” is the question we hear most often at our Keller office. The honest answer: it depends on the material, where the crown sits in your mouth, and how you care for it. Here’s what the research and our clinical experience show.
The short answer: 10–15 years, often much longer
Most modern crowns last 10 to 15 years, and it’s common for a well-placed, well-maintained crown to serve 20 years or more. Studies of zirconia and porcelain-fused-to-metal crowns consistently show survival rates above 90% at the 10-year mark. The variables that move the number are the ones you and your dentist control together: material choice, fit, bite forces, and daily hygiene.
Crown materials compared
- Zirconia. Exceptionally strong and increasingly the standard for back teeth, where chewing forces are highest. Modern zirconia also mimics natural enamel well enough for many front-tooth cases. This is the material we most often recommend at Keller Parkway Dental.
- Porcelain / ceramic. Excellent esthetics for front teeth; slightly more prone to chipping under heavy bite forces than zirconia.
- Porcelain-fused-to-metal (PFM). A proven workhorse for decades. Durable, though the metal margin can eventually show as a dark line near the gum.
- Gold and metal alloys. The longest track record of all — gentle on opposing teeth — but rarely chosen today for visible areas.
What shortens a crown’s life
- Decay at the margin. The crown itself can’t decay, but the tooth under it can. Decay creeping under the edge of a crown is the #1 reason crowns are replaced — and it’s preventable with daily flossing and regular checkups.
- Grinding and clenching (bruxism). Nighttime grinding can chip porcelain and loosen cement. If you wake with a sore jaw or your partner hears grinding, ask us about a custom night guard — it protects the crown and every other tooth too.
- Chewing ice, pens, and hard candy. Crowns are strong, not indestructible.
- Gum disease. A crown is only as stable as the tooth and bone supporting it. Healthy gums are part of crown longevity.
Signs your crown may need attention
Call us if you notice a crown that rocks or feels loose, new sensitivity or pain around a crowned tooth, a visible dark line or gap at the gumline, or a chip you can feel with your tongue. Small problems caught early are usually simple to fix; a loose crown left alone invites decay underneath — which can turn a straightforward re-cement into a root canal or a new restoration.
How we make crowns last at Keller Parkway Dental
Longevity starts on day one. We take the time to prepare the tooth conservatively, capture precise impressions, and check the bite carefully at seating — a crown that meets its opposing tooth evenly wears evenly. From there, your role is simple: brush twice a day, floss along the crown’s gumline daily, wear your night guard if we’ve recommended one, and keep your regular cleanings so we can check the margins before problems start.
What a crown costs in Keller
At Keller Parkway Dental, crowns are $899. If a tooth is too damaged for a filling but doesn’t need to be extracted, a crown is very often the treatment that saves it — and per year of service, it’s one of the best values in dentistry. You can see our current offers on our specials page.
