Short answer
Most dental crowns last about 10 to 15 years, and many last longer. How long yours lasts depends mostly on what is under it: healthy gums and a tooth kept free of new decay at the crown’s edge. Grinding, chewing ice and skipped cleanings are the most common reasons a crown fails early.
What is the typical lifespan of a crown?
A crown is a cap that covers a damaged tooth. It does not decay, but the tooth underneath it can. That is why the lifespan of a crown is really about the tooth and gums around it as much as the crown itself.
Research and everyday practice both show that most crowns are still working a decade after they are placed. Some last 20 years or more. Others need replacing sooner because of a crack, a loose fit or decay at the edge.
Do some crown materials last longer than others?
Material plays a role, but it is not the whole story. Each type has trade-offs between strength and looks.
| Material | Strength | Appearance | Often used for |
|---|---|---|---|
| All-ceramic or porcelain | Good, can chip under heavy force | Most natural | Front teeth |
| Zirconia | Very strong | Tooth-colored, slightly less translucent | Back teeth and front teeth |
| Porcelain fused to metal | Strong | Tooth-colored, a dark line may show at the gum over time | Back teeth |
| Gold or metal alloy | Very strong, wears gently on opposing teeth | Metal color | Back molars out of view |
Your dentist picks a material based on where the tooth is, how hard you bite and whether you grind. You can learn more on our dental crowns page.
What makes a crown fail early?
Decay at the edge
The seam where the crown meets the tooth is the weak point. If plaque sits there, decay can start under the crown. You may not feel it until it is large, which is one reason regular checkups and X-rays matter.
Grinding and clenching
Night grinding puts heavy force on crowns and can chip porcelain or crack the tooth underneath. A custom night guard takes that force instead of your teeth.
Hard and sticky foods
Ice, hard candy, popcorn kernels and using your teeth to open packages can chip a crown. Very sticky candy can pull a crown loose if the cement is already weak.
Gum disease
Gum disease can shrink the gums and bone around a crowned tooth. The crown edge becomes exposed and the tooth can loosen, even if the crown itself is fine.
How can you make your crown last longer?
- Brush twice a day with fluoride toothpaste, paying attention to the gumline around the crown.
- Floss or use a small brush between teeth once a day. Slide floss out sideways if the crown feels snug.
- Wear a night guard if you grind or clench. Replace it when it wears thin; see how long night guards last.
- Do not chew ice, pens or fingernails.
- Keep up with regular exams and cleanings so problems at the crown edge are caught early.
What are the signs your crown needs attention?
- The crown feels loose or moves when you bite.
- You see a chip, crack or dark line at the gum.
- Pain when you bite down, or sensitivity to hot and cold that lasts.
- Swelling, a pimple-like bump on the gum, or a bad taste near the tooth.
- Floss catches or shreds at the same spot every time.
Pain or swelling under a crown can mean the nerve inside the tooth is infected. In that case the tooth may need a root canal before a new crown is made. Despite its reputation, a root canal relieves pain rather than causing it.
What should you do if a crown comes off?
- Keep the crown in a small bag or container and bring it with you.
- Do not use super glue. It can damage the crown and the tooth.
- Chew on the other side and avoid sticky foods.
- Call us during office hours. If the tooth is sensitive, a little denture adhesive or temporary dental cement from a pharmacy can hold the crown in place for a short time.
How much does a crown cost to replace?
At Richmond Dental Care, self-pay crowns start at $1,199. Our price list shows that and other common treatments. Replacing a crown takes two visits, with the new crown placed about 5 days after the first. We do not offer single-visit crowns; see same-day dental crowns for how we get you out of pain quickly instead. If the tooth also needs a root canal or other work first, we give you a written estimate before anything is done. Insurance is verified ahead of time, and financing through Cherry, Sunbit and CareCredit is available.
We also offer Saturday crown appointments for people in Richmond and Fort Bend County who cannot take time off on weekdays.
When to call us
Call us if a crown is loose or has come off, if it hurts to bite on a crowned tooth, or if you see a crack or swelling near it. Swelling or a bad taste can mean infection, so do not wait for your next cleaning. Call (832) 612-2831 — we’re open Tuesday, Wednesday and Saturday, 9am–3pm.
Frequently asked questions
Some do, especially with good home care and regular checkups. But it is safer to expect that a crown will need replacing at some point, and to keep up with checkups so problems are found early.
Yes. The crown cannot decay, but the natural tooth at the crown’s edge can. Brushing along the gumline and flossing are the best protection.
Yes. A broken or missing crown leaves the tooth weak and open to decay and cracks. It can break further or become infected, so call to have it checked soon.
No. Whitening only works on natural enamel. If you plan to whiten, do it before a front crown is made so the crown can be matched to your new shade.
