If you are weighing up a dental implant, the question behind the question is usually whether it will actually last. The reassuring answer from the research is yes, for most people. A widely cited systematic review put ten-year implant survival at about 96.4 percent, and longer studies show roughly 94 percent of implants still in place at fifteen years. Some cohorts followed for twenty years and beyond report survival in the 90 to 95 percent range. So dental implants are one of the most durable options in dentistry, but durability is not the same as fit-and-forget, and the post and the crown age differently.
Key takeaways
- Around 96 percent of implants are still functioning at 10 years, and about 94 percent at 15 years, according to large reviews.
- The titanium post (the part in the bone) usually outlasts the crown (the visible tooth) attached to it.
- The most common reason implants fail late is gum and bone infection around them, called peri-implantitis, which is largely preventable.
- Smoking, uncontrolled diabetes, poor cleaning and grinding are the biggest risk factors you can influence.
- With good hygiene and regular reviews, many implants last decades, but the crown may need replacing once during that time.
The post and the crown are two different lifespans
An implant is really two parts. The first is the screw-shaped post made of titanium or a titanium alloy, which fuses to the jawbone in a process called osseointegration. The second is the crown, bridge or denture that attaches on top and does the visible work of chewing and smiling. These wear out on very different timelines. The post, once it has integrated, can last for decades and often for life. The crown takes the daily load and is exposed to wear, staining and the occasional knock, so it is the part more likely to need replacing during the life of the implant. Studies tracking the prosthetic part specifically show shorter survival than the post, which is normal and expected rather than a sign of failure.
What the survival numbers really mean
| Time point | Implant (post) survival | What it means for you |
|---|---|---|
| 5 years | Around 97 to 98 percent | Early failures are uncommon and usually happen in the first year if at all |
| 10 years | About 96 percent | The large majority of implants are still doing their job |
| 15 years | About 94 percent at the implant level | Most are intact; the crown may have been refreshed by now |
| 20 years + | Roughly 90 to 95 percent in long cohorts | Implants are a genuinely long-term solution for most people |
One nuance worth knowing: survival measured per patient is a little lower than survival measured per implant, because someone with several implants is more likely to have at least one issue over time. That is statistics, not a warning, but it is why people having full-arch work should pay even closer attention to maintenance.
Why implants fail when they do
Most late implant problems come down to one issue: infection of the gum and bone around the implant, known as peri-implantitis. It behaves a bit like gum disease around a natural tooth. Plaque builds at the gum line, the tissue becomes inflamed, and if it is not controlled the supporting bone slowly recedes until the implant loosens. The encouraging part is that this is largely preventable with cleaning and monitoring. Other causes include implants placed into too little bone, excessive bite force from grinding, and rare mechanical issues like a fractured screw.
The four risk factors you can actually control
Smoking
Smoking is the single biggest modifiable risk. It impairs healing and blood supply to the gums and is consistently linked to higher implant failure. Cutting down or quitting before and after placement measurably improves the odds.
Blood sugar control
Well-managed diabetes is not a barrier to implants, but poorly controlled blood sugar slows healing and raises infection risk. Getting levels steady before surgery helps.
Daily cleaning
Implants cannot get cavities, but the gum around them still needs the same care as a natural tooth, plus a little extra attention under the crown. Most people do well with a soft brush and interdental brushes or floss designed for implants.
Grinding and clenching
Heavy night-time grinding loads the implant and the crown beyond what they were designed for. If you grind, a night guard protects the investment. Our guide on gum health covers the early warning signs that the tissue around any tooth or implant is struggling.
How implants compare with the alternatives over time
Longevity is one of the main reasons people choose implants over a bridge or denture, but it is not the only factor. A bridge typically lasts ten to fifteen years and a denture needs relines and remakes over time. We compare all three side by side, including the long-term cost picture, in our guide on implant versus bridge versus denture, and if you are replacing several teeth at once the All-on-4 guide is the relevant read.
What maintenance actually involves
Looking after an implant is not complicated. It means cleaning around it daily the way you would a natural tooth, keeping up regular professional cleans and check-ups so any early gum inflammation is caught and reversed, and protecting it from grinding if that applies to you. A professional review will usually include checking the gum around the implant, the bite, and occasionally an X-ray to confirm the bone level is holding. Our professional cleaning guide explains what a maintenance visit covers.
What it costs to place and maintain an implant
Implant fees vary with the number of teeth, whether bone grafting is needed and the type of crown. General market figures are covered in our implant cost guide.

Frequently asked questions
Do dental implants last a lifetime?
The titanium post often lasts for life once it has fused to the bone, especially with good care. The crown on top is more likely to need replacing once over several decades because it takes the daily wear.
What is the most common reason an implant fails years later?
Peri-implantitis, an infection of the gum and bone around the implant. It is closely tied to plaque control and is largely preventable with daily cleaning and regular reviews.
Can a failed implant be replaced?
Often yes. If an implant is lost, the site is allowed to heal and is assessed for a new implant, sometimes with a bone graft first. Your dentist will explain what your specific site allows.
Does grinding my teeth shorten an implant's life?
It can. Grinding overloads both the implant and the crown. A custom night guard is a simple, low-cost way to protect the work if you clench or grind.
Are cheaper implants less durable?
Not necessarily, but the brand, the planning and the skill of placement all matter. The survival figures quoted here come from well-placed implants maintained properly, so the conversation to have is about the whole package, not just the headline price.
The headline is genuinely positive. For most people who look after them, implants are a decades-long solution. The variable that matters most is not luck, it is the daily cleaning and the regular reviews that keep the gum and bone around the implant healthy.
