With good care, the titanium implant post often lasts 25 years or longer, sometimes a lifetime, while the crown on top typically needs replacement every 10 to 15 years from normal chewing wear. Long-term studies show roughly 90 to 95 percent of dental implants are still functioning at the 10-year mark.

That gap surprises a lot of our patients. The fixture in the bone and the tooth-shaped crown on top are two different parts with two different timelines. Once you understand that, the question "how long will this last?" gets a much clearer answer. At Inspire Dental in Tigard, we walk King City and Bull Mountain patients through this every week, because most people weighing an implant want to know they are making a once-in-a-lifetime decision.

How long do dental implants actually last?

A dental implant is two pieces working as one. The first is the titanium post that sits in your jawbone, acting as a replacement root. The second is the crown (and a small connector called the abutment) that screws onto the post and looks like a tooth. They wear at very different rates.

According to systematic reviews published in journals like Clinical Oral Implants Research, roughly 90 to 95 percent of dental implants are still in function at the 10-year mark. Many go far beyond that. The crown, on the other hand, takes a daily beating. The ADA notes that implant crowns typically need replacement every 10 to 15 years. Same as a crown on a natural tooth. That's normal, and it does not mean the implant failed.

So when a patient from Summerfield asks if their implant will last the rest of their life, the honest answer is: the post probably will. The crown on top will likely be swapped at some point. That is a much smaller, less expensive procedure than placing a new implant.

Why does the fixture outlast the crown?

The post lasts because of a biological lock called osseointegration. As the NIDCR describes it, bone cells grow directly onto the titanium surface and fuse with it. There is no glue, no cement, no moving part. Your jawbone treats the implant like part of itself.

The crown does not get that protection. It sits above the gumline and absorbs every bite, every grind, every cup of coffee. Porcelain and zirconia are tough, but they are not indestructible. Over a decade or two, a crown can chip, wear flat in spots, or stain in ways a polish cannot fix. The good news? We can unscrew or remove the crown and place a new one without disturbing the post underneath.

That's the whole trick.

What shortens an implant's life?

Most implant failures are not random. They trace back to a handful of preventable causes.

• Peri-implantitis. The American Academy of Periodontology identifies this as a leading cause of late implant failure. It is an infection of the gum and bone around the implant, very similar to gum disease around a natural tooth. If it is caught early, we can treat it. If it is ignored, bone melts away and the implant loosens.

• Smoking. Peer-reviewed studies and CDC data consistently show smokers experience significantly higher implant failure rates than non-smokers. Nicotine restricts blood flow to the gums and slows healing.

• Uncontrolled diabetes. The ADA flags this as a real risk factor. When blood sugar runs high, healing slows and infection risk climbs.

• Untreated bruxism. Patients who grind their teeth at night can crack an implant crown the same way they crack natural enamel. We see this often in stressed-out professionals commuting the Highway 217 corridor to tech jobs.

• Skipped cleanings. Plaque builds up at the gumline around an implant just like it does around a tooth. No exceptions.

What helps implants last decades?

The patients with 20-plus-year-old implants do the same handful of things, consistently. Nothing exotic.

• Brush twice a day and floss or use a water flosser around the implant. Pay attention to the gumline where the crown meets the gum.

• Keep your hygiene visits twice a year so we can use implant-safe instruments to clean the post without scratching it.

• Wear a nightguard if you grind. Custom-fit, not the drugstore kind.

• Get gum disease treated promptly. Even mild bleeding around an implant deserves a look.

• Don't smoke. If you do, even cutting back helps healing and longevity.

Simple as that.

When does a crown or implant need replacing?

Here are the signs we look for at routine visits, and the ones you should bring to our attention between visits:

• A visible chip, crack, or worn-down edge on the crown

• The crown feels loose or wiggles when you press it with your tongue

• Food traps under or around the crown that didn't before

• Gum recession exposing a metallic edge or the abutment underneath

• Pain, swelling, or any mobility at the implant site

A new crown on a healthy implant is a relatively quick appointment. A failed implant is a bigger conversation. That is why we'd much rather see you for something small early than something serious late.

Caring for your implant in Tigard

A retired teacher from King City came in last spring for her regular cleaning. She had received her implant from one of the legacy dentists at this Pacific Highway location more than 18 years ago. The post looked great on her X-ray. Her bone levels had barely changed. But the crown had a hairline crack from years of crunching ice. We replaced just the crown. Same implant, fresh tooth, same afternoon plan to grab coffee on her way home.

That is the longevity story most of our Bull Mountain and Tualatin patients can expect when they stay on top of cleanings. We monitor implant bone levels with periodic X-rays, watch for early peri-implantitis, and flag wear on the crown before it becomes a fracture. If something feels off, a click when you chew, tenderness in the gum, a sense that the bite is different, tell us early.

Every single time.

The post is built for a lifetime. The crown is built for a decade or two. Plan for both, and you plan well.

Frequently Asked Questions

Can a dental implant last a lifetime?

The titanium post often can, especially in patients who don't smoke, control any systemic conditions like diabetes, and keep up with hygiene visits. Many of our patients are well past 20 years on the same implant fixture. The crown on top, however, is more likely to be replaced once or twice over a long lifespan as a normal maintenance step.

How often does the crown on an implant need to be replaced?

The ADA suggests most implant crowns last 10 to 15 years before wear, chipping, or staining warrant replacement. Some go longer. Heavy grinders or patients who frequently chew hard foods may see crowns wear faster. Replacing the crown is straightforward and does not involve removing the implant post in the bone.

Does insurance cover replacing an implant crown?

Many dental plans cover crown replacement after a certain number of years, often five to seven, similar to how they cover crowns on natural teeth. Coverage for the original implant placement varies more widely. We are happy to review your specific plan during a consultation so you know what to expect before any work is scheduled.

Can a failed implant be redone in the same spot?

Often yes, though it depends on how much bone remains. If an implant fails due to infection or bone loss, we sometimes need a bone graft and a healing period before placing a new implant in the same location. Acting quickly when symptoms appear preserves your options.

Do older adults get the same lifespan from implants as younger patients?

Yes, age alone is not a barrier. Plenty of our patients in their 70s and 80s have received implants that are still going strong years later. What matters more than age is bone health, gum health, and managing conditions like diabetes. Many retirees in Summerfield and King City are excellent implant candidates.
