Key Takeaways
- The titanium implant post usually lasts 20 years or more, and often for life.
- The crown on top wears faster and may need replacing after 10 to 15 years of chewing.
- Gum infection around the implant (peri-implantitis), smoking, diabetes, and teeth grinding are the main threats.
- Daily cleaning and regular checkups do more for implant lifespan than any brand or material choice.
Most Dental Implants Last Two Decades or More
A review of 23 long-term studies covering 7,711 implants found a 94.6% survival rate after an average of 13.4 years. So, how long do dental implants last? The titanium post typically lasts 20 years or more, and in many patients it lasts for life, while the crown attached to it usually needs replacing sooner. If you are weighing an implant against a bridge or denture, that difference matters for planning both cost and future visits. Knowing what to expect from implant dentistry helps you plan for future restoration work and build habits that protect your investment.
What Are Dental Implants?
Dental implants are a tooth replacement option if you are missing one or more teeth. Unlike other options like dentures, dental implants do not require adhesive to stay in place and look and feel like your natural teeth.
Dental implants are surgically placed into the jawbone. After it has healed, a crown is placed on top. An implant has three parts, which include the titanium post in the bone, a small connector called an abutment, and the crown you see. Each part wears at a different rate, so a single lifespan number can mislead.

How Long Do Dental Implants Last?
If you’re considering dental implants, you may wonder how long they’ll last. The post itself is the most durable part. A 2024 meta-analysis in Clinical Oral Investigations found that about 4 out of 5 implants were still in place after 20 years. This is because the implant bonds with the surrounding bone tissue, forming a solid foundation for a prosthetic tooth.
While the post can be permanent, the crown attached may need to be replaced due to normal wear and tear. A systematic review in Clinical Oral Implants Research reported that 93.9% of metal-ceramic implant-supported restorations were still working after 10 years. How long the crown on your dental implants lasts depends on your bite force, grinding habits, and what you chew. Abutment screws can also loosen over time, which is usually a quick fix.
Why Do Some Dental Implants Fail?
Dental implants are one of the most successful procedures, but like any other medical procedure, they are not perfect. Dental implant lifespan drops when one of these problems develops:
1. Peri-implantitis: Peri-implantitis is a gum disease that attacks dental implants with an infection, damaging the bone around the implant. This condition can result in a loose implant. A 2025 meta-analysis in the Journal of Periodontology found that it affects about 21% of implant patients, with smoking and alcohol use, a history of gum disease, and diabetes as the main risk indicators.
2. Failed osseointegration: Failed osseointegration occurs when the bone does not fuse with the implant, leaving it unstable. It usually shows up within the first few months after surgery. This is often linked to factors such as bone quality or smoking. However, it can also be related to the surgical technique used by your dentist.
3. Lifestyle and oral hygiene practices: If you grind your teeth or don’t brush and floss regularly, this can put extra stress on your implants and cause them to fail. A history of gum disease can also increase your risk of implant failure.
How Can You Protect Dental Implant Longevity?
The answer to “how long do dental implants last?” depends as much on what happens after surgery as during it. Five factors have the biggest effect:
- Oral hygiene: Proper brushing and flossing keep your implant clean and free of bacteria. Implants cannot decay, but the gum and bone around them can become infected the same way they do around natural teeth. Visit your dentist regularly for checkups.
- Location of the implant: Implants placed in the lower jaw tend to be more successful than those in the upper jaw, because the lower jaw typically has denser bone to support the implant. Upper back teeth sometimes need a bone graft first.
- Overall health: If you have certain medical conditions like diabetes, keeping blood sugar controlled lowers your risk of infection around the implant. Quitting smoking before surgery also improves healing.
- Bite protection: For patients who grind at night, Dr. David Tycast often recommends a custom night guard, which Dental On First fabricates for implant patients and natural-tooth patients alike. Patients who play hockey or other contact sports should wear a sports guard as well.
- The experience of your dentist: Dr. Tycast has placed and restored implants since completing his dental studies at the University of Minnesota School of Dentistry in 2007, and he plans each case around the patient’s bone, bite, and health history before surgery.
Planning for an Implant That Lasts
If you already have an implant, ask for it to be checked at your next cleaning, especially if you notice bleeding, swelling, or a change in your bite. Small problems like a loose screw or early gum inflammation are far easier to treat than bone loss. If you are still deciding whether an implant fits your situation, bring your medical history and any past dental X-rays to your consultation so the team can assess bone levels and risk factors up front. Knowing how long dental implants will last for you starts with that first exam.

FAQs
Common signs of dental implant failure include gums that bleed or swell around the implant, pain when biting, a loose feeling, or pus near the gumline. Some bone loss causes no symptoms, which is why dental X-rays at checkups matter.
In many cases, a failed dental implant can be replaced. The dentist removes the implant, lets the site heal, and may add a bone graft before placing a new one. A systematic review found that implants in grafted bone had 10-year survival rates between 91.6% and 100%, similar to non-grafted sites.
No. The titanium post and crown cannot decay. However, the gum tissue around them can become inflamed, so flossing and cleaning around the implant are just as necessary as with natural teeth.
Most patients do well with checkups every six months. Patients with a smoking habit, history of gum disease, or diabetes may need to visit more frequently.
Implants usually last longer because they do not depend on neighboring teeth for support. A bridge relies on the teeth on either side, and decay or gum disease in those teeth can shorten its life.
