Many people in Stamford, CT ask how long do dental implants last, and the research is encouraging. In one large long-term study, 94% of implants were still in place after 15 years. That does not mean every implant will last that long. Your own results depend on your health, your daily habits and the care you keep up after the implant is placed.
An implant has two main parts that age in different ways. The titanium post sits in the jawbone and is built for the long term. The crown on top takes the daily wear, so it may need to be replaced sooner. Knowing the difference helps you plan with your dentist. At Newfield Dental, our team guides you through every stage of dental implants in Stamford, CT, from the first exam to the final crown.
How long do dental implants last on average?
Researchers followed 10,871 implants placed in 4,247 patients for up to 22 years. They tracked how many implants stayed in place over time. The numbers stayed high, and they dipped slowly as the years went by.
| Years after placement | Implants still in place |
|---|---|
| 3 years | 98.9% |
| 5 years | 98.5% |
| 10 years | 96.8% |
| 15 years | 94.0% |
Cumulative implant survival from a published cohort study of 10,871 implants. These are research figures, not Newfield Dental’s results.
The study also measured the bone around each implant. Bone loss stayed small, averaging about 0.49 mm at 8 to 10 years. That matters because steady bone is what keeps an implant firm.
These figures come from one dentist’s patients over many years. They show what is possible, not what is promised. Your dentist can tell you how your own mouth compares.
So, how long do dental implants last for most people? Many last well past 10 years. The American Dental Association calls implants an excellent long-term option for restoring your smile.
The implant post and the crown wear differently
A dental implant is built in layers. A small titanium post goes into the jawbone. The bone then grows around it and holds it in place. A connector and a custom crown are added on top.
The healing phase sets the stage for the years that follow. For the first three to six months after surgery, the implant sits beneath the gum and slowly bonds with the jawbone. During that time you may wear a temporary denture and eat a soft diet. The ADA calls this bonding osseointegration, and it is what makes an implant so strong.
The post sits below the gum line, where it is protected. The crown is the part you chew with every day. Over time a crown can chip, wear down or loosen. It may need to be replaced while the post stays put.
That is why a dentist may talk about two separate lifespans, one for the post and one for the crown. You can read more about how crowns work on our dental crowns page.
At Newfield Dental, your care team includes Dr. Stephen Poon and, for surgery, an oral and maxillofacial surgeon referred by our practice. The full implant process usually takes six to eight months from start to finish.
How long do dental implants last if you smoke or have diabetes?
Your health matters more than your age. The ADA says your general health is more of a factor than your age when it comes to implants. It also notes that chronic illnesses such as diabetes may interfere with healing after surgery, and that tobacco can slow healing.
The long-term study points the same way. Cigarette smoking and diabetes were both linked to a higher chance of implant failure.
None of this means you cannot have an implant. It means your dentist should look at your health history first. At Newfield Dental, an implant evaluation starts with an exam, X-rays and a review of your health history.
Gum health matters too. The same study tracked peri-implantitis, which is inflammation that damages the bone around an implant. It appeared in 2% of implants at 2 to 3 years and in 7.1% at 8 to 10 years. An earlier, milder inflammation called peri-implant mucositis appeared in about 12% of implants at 8 to 10 years.

How to make dental implants last longer
When patients ask "how long do dental implants last," the honest answer includes their own habits. Daily care and regular visits do most of the work.
Clean around the implant every day
Brush twice a day and clean between your teeth once a day, just as you would with natural teeth. Plaque builds up around an implant the same way it does around a tooth. Your dentist or hygienist can show you the best tools for the space around your implant.
Keep your checkups and cleanings
A professional cleaning lets your team check the gums and bone around the implant before a small problem grows. At a checkup your dentist also looks at how the crown fits and how your bite comes together, and may take X-rays to see the bone. Patients with a history of gum disease may need extra support. Our periodontal maintenance visits are one option your dentist may recommend.
Build a strong foundation first
An implant needs enough healthy bone to hold it. If you have lost bone, your dentist may suggest a graft before the implant goes in. Our post on bone grafting for dental implant preparation explains how that step works.
Follow your aftercare instructions
How you treat the implant in the first weeks matters. Stick to the soft diet your dentist recommends while the site heals, and keep your follow-up visits. Our home care instructions page lists what to do after a procedure at our office.
Look after your overall health
If you smoke, talk to your dentist or doctor about quitting before surgery. If you have diabetes, work with your doctor to keep it under control. Both were linked to implant problems in the research.
Signs your implant needs a checkup
Call your dentist if the gums around an implant bleed, look red or feel swollen. Pain when you bite, a crown that feels loose, or a shifting feeling in the tooth are also reasons to call. Catching a problem early gives your dentist more options.
Do not wait for your next routine visit if something feels wrong. A short exam can tell you whether the implant needs care, and a quick visit now can spare you a bigger problem later. Our team in Stamford would rather see you early than hear about a problem months after it began.
Frequently asked questions
Can dental implants last a lifetime?
Some can. The ADA calls implants an excellent long-term option, and many patients keep theirs for decades with good care. No dentist can promise that for any one patient, though. Ask for an honest estimate based on your health, your bone and your habits. The best predictor is how well the implant is planned, placed and cared for over time.
Do dental implants need to be replaced?
The titanium post often stays for many years. The crown on top takes daily wear and may need to be replaced sooner. Your dentist will check both at each visit and tell you if either one needs attention. In many cases a worn or loose crown can be replaced without removing the post.
Can dental implants get cavities?
The post and crown are not natural tooth structure, so they do not decay the way a tooth does. The gums and bone around them can still become inflamed or infected. Daily cleaning and regular checkups protect the tissue that holds your implant in place.
How often should I see the dentist with dental implants?
Your dentist will set a schedule based on your gum health and your risk factors. Patients with a history of gum disease may need more frequent visits. Keep your regular checkups and cleanings so your team can watch the bone and gums around the implant.
