If you are weighing up an implant, knowing how long dental implants last matters as much as how it looks.
You may have heard that an implant can last a lifetime with proper care. The research behind that promise is worth seeing for yourself.
This guide covers the figures, what shortens an implant’s life, how to protect it and what applies to full arches.
How Long Do Dental Implants Last: The Answer in Numbers
With good care, the titanium post of a dental implant can last 20 years or more, and often a lifetime. A 2021 study in Clinical Implant Dentistry and Related Research followed 10,871 implants for up to 22 years. It found 96.8% still in place at 10 years and 94.0% at 15. Hospital guidance puts the success rate at 80 to 95% over 15 years in patients with healthy mouths. How long dental implants last for any one person depends on their health and daily care, so nobody can promise an exact figure.
The study’s figures, year by year:
| Years since placement | Implants still in place |
|---|---|
| 3 years | 98.9% |
| 5 years | 98.5% |
| 10 years | 96.8% |
| 15 years | 94.0% |
The study cannot give the average life of dental implants, because most were still in place when it ended.
Dental Implant Lifespan: What the Figures Mean
Each source counts something different. The study counts implants still in place, while the hospital guidance gives a success rate. The guidance also reports a lower rate, 80 to 85% over seven years, for patients who have gum disease. Healthy gums play a real part in how long dental implants last.
How Long Does a Dental Implant Last: The Post & the Crown
A dental implant has two parts, and each ages in its own way. The titanium post sits in your jawbone in place of the tooth root. On top sits the crown or bridge, the part you see and chew with.
The teeth on your implants will wear over time, as crowns and bridges on natural teeth do, so the answer to how long dental implants last comes in two halves. The post should stay in place, while the crown usually lasts 10 to 15 years before it needs renewing.
Why the Titanium Post Lasts So Long
After placement, your jawbone heals around the post and bonds with it. Our implant page explains that the screw’s design and material promote fusion with the bone. Once that bond forms, the post can stay in place for many years.
How Long Will a Dental Implant Last?
Your own health and habits shape how long dental implants last. The outcome depends on your jawbone, your gums and whether you smoke. The research names these factors:
- Smoking. Smokers have a much greater failure rate, and the 22-year study linked smoking with failure.
- Gum disease. Success rates are lower in patients who have gum disease.
- Cleaning. Poor cleaning can lead to bone loss around an implant.
- Grinding. Grinding your teeth can overload implants.
- Diabetes. The 22-year study linked diabetes with failure too.
Your dentist will weigh each of these, because together they affect how long a dental implant lasts.
Helpful Tip: If you smoke, ask about support to stop before your treatment starts.
Why Your Assessment Looks at Your Health First
To have an implant, you need reasonable general health, good oral hygiene and enough jawbone. Your assessment will therefore check your gums, bone and general health first.

How Do You Keep Dental Implants Healthy?
When it comes to how long dental implants last, daily care is the part in your own hands.
Clean every day. Meticulous cleaning is critical to long-term success. Without it, the gum around an implant can bleed and swell, and infection can reach the bone.
Keep your check-ups. Implant patients are usually asked to see a dentist or hygienist every three to six months. At those visits, the dentist or hygienist will check the implants and clean them professionally.
Expert Tip: Clean around your implant crown as carefully as around your natural teeth.
Why Regular Maintenance Makes a Measurable Difference
One study followed 100 patients with fixed crowns or bridges on implants. It compared those who kept up regular maintenance visits with those who did not. Of the first group, 96.8% kept their implants, against 86.8% of the second. If your last check-up was a while ago, book one of our regular hygiene appointments and ask us to check your implants.
Do Dental Implants Last Forever: Single Teeth & Full Arches
Dental implants are made to replace a missing tooth permanently. Mos implants can last a lifetime with proper care. The evidence ties the life expectancy of dental implants closely to health and daily care. That’s why the answer to how long dental implants last differs from one person to the next.
How Long Do All-on-4 Implants Last?
With All-on-4, a full arch of teeth sits on four titanium implants. Our all-teeth implant page calls it a permanent and stable solution. The same care applies as for a single implant. The bridge takes the wear, and bridges on implants may need refurbishing with time. Our All-on-4 implants guide explains the treatment.
Frequently Asked Questions – Dental Implant Lifespan
How long implants last depends on your health, smoking and daily care, and while the post is made to stay, the crown on top may need replacing.
How long does an implant last if you smoke?
Smoking makes failure more likely, though nobody can put a number of years on it. Smokers have a much greater failure rate, and the 22-year study found the same link. Some hospital implant services ask patients to stop at least six months before treatment, so ask your dentist about support to stop.
Are dental implants permanent?
Yes. The titanium post is made to stay. Our single tooth implant page says an implant is designed to last a lifetime with proper care. In the 22-year study, 94.0% of implants were still in place after 15 years. The crown on top may need replacing, but that does not mean replacing the implant.
How strong are dental implants?
They are strong enough to bite and chew like natural teeth. The titanium screw’s design and material promote fusion with the bone, which gives it stability. Once healed, an implant looks, feels and works like a natural tooth. Grinding is the strain to watch for, because it can overload an implant.
What happens to dental implants after 20 years?
The longest study we cite followed implants for up to 22 years. Most were still in place when their follow-up ended. The study’s last reported figure is 94.0% still in place at 15 years. Over that time, the crown or bridge on top may need refurbishing because of wear.
Can the crown on an implant be replaced?
Yes. The teeth on your implants will wear over time and may need replacing. The titanium post underneath usually stays where it is, so your dentist can renew a worn crown on the same implant. Ask your dentist to check it at each visit.
Does diabetes affect how long implants last?
It can. The 22-year study linked diabetes with implant failure. Its authors advise considering risk factors like this before placing an implant. Tell your dentist about diabetes at your assessment, so your treatment takes it into account. Regular check-ups then let your dentist keep a close eye on the implant.
How long do you wear a temporary bridge with All-on-4?
You usually wear it for three months or more. Our all-teeth implant page explains that a temporary bridge is made on the day of placement. It stays securely in place while you heal. The final bridge goes in once healing is complete.
Do implants help keep the jawbone healthy?
Yes. Our implant pages explain that implants help maintain your jawbone’s density and prevent jawbone recession. That also helps preserve the shape of your face over time.
How Long Do Implants Last: What to Remember
As for how long dental implants last, the short version is encouraging. The titanium post is made to stay. In one 22-year study, 94.0% of implants were still in place after 15 years. The crown on top takes the daily wear and may need renewing along the way. Smoking, gum disease, grinding and diabetes can all shorten an implant’s life, while daily cleaning and regular check-ups protect it.
What to keep in mind:
- The post is made to last. Our implant page says it’s designed to last a lifetime with proper care.
- The figures are reassuring. Most implants in the 22-year study were still in place at 15 years.
- The crown may need renewing. Wear on the crown is normal over time.
- Your health plays a part. Smoking, gum disease and diabetes raise the risk of failure.
- Maintenance makes a difference. Patients who kept up maintenance visits kept their implants more often.
At your assessment, your dentist will check your gums, bone and general health, and explain what that means for your own implant. From there, the routine is simple. Clean around your implants every day and keep your check-ups and hygiene visits. Mention any grinding or changes in your health, too. Those habits give your implant the best chance of lasting for many years.
