The honest answer: 10–15 years is typical, and a good crown that's cared for often runs 20 or more. I've seen crowns from the 1980s still doing their job, and I've seen crowns fail in three years. The difference is rarely luck — it comes down to four things, and you control two of them.
What the lifespan actually depends on
1. The material
Today's sintered zirconia is the most durable crown material in common use — dramatically stronger than the porcelain-fused-to-metal crowns of twenty years ago, which could chip their porcelain veneer layer. A monolithic zirconia crown has no veneer layer to chip; failures of the crown itself are rare. eMax (lithium disilicate) is somewhat less strong but still excellent, and earns its keep on front teeth where translucency matters. (More on materials in our CEREC vs. lab-made crown guide.)
2. The fit
This is the factor patients never see and can't shop for on price lists. A crown meets your tooth at a margin — a seam, usually right around the gumline. The tighter and smoother that seam, the less chance bacteria have of getting underneath. Crowns crafted by an experienced lab ceramist against a clean digital scan fit better than rushed work, and fit is destiny: most crowns don't break — they get undermined.
3. Your habits
A crown is strong, but physics is undefeated. Chewing ice, un-popped popcorn kernels, and hard candy is how crowns (and natural teeth) crack. And if you grind or clench at night, you're applying hundreds of pounds of force to the crown for hours — a simple nightguard is the cheapest crown insurance there is. We make them; ask at your visit.
4. The tooth underneath
The crown can be perfect and the tooth can still get cavities at the margin. Brushing along the gumline and flossing around a crowned tooth matters more, not less, after the crown goes on. Decay at the margin is the number-one reason crowns get replaced.
Warning signs your crown is failing
- A dark line or gap at the gumline — the margin may be opening or the gum receding past it.
- Food constantly catching around one crown — something has changed shape.
- New sensitivity or pain when you bite — possible decay underneath or a crack in the root.
- A rough or chipped edge your tongue keeps finding.
- Looseness. A rocking crown needs attention this week, not this year — the cement seal has failed and bacteria are getting in.
None of these mean the tooth is lost. Caught early, many of them are simple fixes. Ignored, they turn a $799 problem into a root canal or an extraction-and-implant decision.
Will insurance pay to replace an old crown?
Usually yes, if there's a legitimate clinical reason. Most plans have a replacement clause of 5–8 years — once your crown is older than that, the plan will typically cover ~50% of a replacement just as it did the original. If you have an aging crown with any of the warning signs above, there's a decent chance insurance shares the bill. Text a photo of your card to (801) 254-0713 and we'll check your plan's clause before you come in. The full cost math is in our crown cost guide.
How we stack the odds in your favor
Every crown we place is full-strength, lab-sintered zirconia, designed by an experienced ceramist, seated by the same dentist who prepped it — and we put our money where our mouth is: if your crown ever breaks, we replace it. No questions asked. That guarantee is easy to offer when you've placed thousands of crowns since 2006 and know how rarely good ones fail.
Got an aging crown — or a tooth that needs its first one?
$799 flat. Exam, X-rays, and core buildup included. Replacement guarantee on every crown.
Common questions
How long does a crown last on average?
10–15 years is typical; well-made, well-cared-for crowns commonly last 20+. Material, fit, your bite habits, and hygiene at the margin decide which end of that range you land on.
What's the most common reason crowns fail?
Not breakage — decay creeping under the crown's edge. That's why fit quality and brushing along the gumline matter more than anything else.
Do crowns wear out faster if I grind my teeth?
Yes — grinding is one of the hardest things you can do to a crown (and to your natural teeth). A nightguard is inexpensive protection; we can make one for you.
Will insurance cover replacing my old crown?
Most plans cover ~50% of a replacement once the crown is past the plan's replacement clause, usually 5–8 years, when there's a clinical reason. We'll verify your plan's exact terms for free.
