Can a dental implant last 40 years? You want to know if your investment in your mouth will stay strong for the rest of your life. Dental implants act as artificial roots for your missing teeth, and they sit directly in your jawbone. Modern dentistry offers options like All on 4 dental implants to replace a full set of teeth. If you take care of them, they can last for many decades. We will discuss the science, the costs in Australian dollars, and the steps you must take to make your implants last.
Can dental implants last 40 years?
Yes, a dental implant can last 40 years. Evidence shows that the very first patient to receive modern dental implants kept them for more than 40 years. In 1965, a Swedish doctor named Per Ingvar Branemark placed the first modern titanium implants into a patient named Gosta Larsson. Larsson had lost his teeth, and the new implants allowed him to eat and speak normally. He used those exact same implants until he died in 2006, which was 41 years later.
Modern clinical studies back up this case. Research shows that titanium is highly compatible with human bone. Your body does not reject titanium. Instead, the bone grows around the screw and locks it in place. Dentists call this process osseointegration. Once this process finishes, the screw becomes a permanent part of your jaw. If you keep your gums clean and do not smoke, the metal root will easily last 40 years.
What is the success rate of dental implants after 40 years?
The success rate of dental implants after 40 years is over 90 percent. All on 4 dental implants. A study published in the International Journal of Oral and Maxillofacial Implants tracked patients over several decades. The researchers found that 90 to 95 percent of implants stayed healthy and did not need removal.
However, you must know the difference between the implant screw and the tooth crown. The implant screw is the metal part under your gums. The crown is the plastic or porcelain tooth that you see. While the metal screw has a success rate of over 90 percent after 40 years, the crown on top does not last that long. The crown will wear out from chewing food. You will need to replace the crown every 15 to 25 years. Replacing a crown is a simple procedure that does not require surgery.
Can dental implants last 60 years?
Yes, dental implants can last 60 years if you receive them at a young age and maintain excellent oral health. The second patient in the world to get modern titanium implants was Sven Johansson. He received his implants in 1967 when he was a young man. He lived for more than 50 years with those same implants and they stayed strong. The titanium did not break down or rust.
To make an implant last 60 years, you must get the implant when you are young and keep your mouth very clean. The metal itself does not wear out. Titanium is stronger than human bone. The only thing that can destroy the implant is the loss of the bone that holds it. If your bone remains healthy, the implant will stay in place for 60 years or more.
What happens to dental implants after 30 years?
After 30 years, your dental implant screw will remain fused to your bone, but the surrounding mouth will change. Clinical data shows that three major things happen after 30 years.
First, the porcelain crown on top of the implant will show wear. You might notice small cracks or chips in the porcelain. The dentist will need to unscrew the old crown and make a new one.
Second, your natural teeth will shift. Natural teeth sit in a tiny ligament that allows them to move over time. Implants do not have this ligament. The implant stays in the exact same spot. After 30 years, you might notice small gaps between your implant and your natural teeth.
Third, your jawbone will change. As you get older, your jawbone naturally loses some density. However, the implant actually protects the bone. When you chew, the implant stimulates the bone and keeps it strong. The bone around the implant will stay thicker than the bone in areas where you have missing teeth.
At what stage do dental implants fail?
Dental implants fail either in the first six months after surgery or many years later due to gum disease. The first stage of failure is early failure. This happens within the dental implant surgery. During this time, your bone must grow around the titanium screw. If the bone does not heal properly, the implant will become loose. Early failure happens if the surgeon places the implant incorrectly, if you get an infection, or if you put too much pressure on the tooth before it heals.
The second stage of failure is late failure. This happens years after the surgery. Late failure occurs when bacteria get under the gums and destroy the bone that supports the implant. If you do not clean your teeth, the bone will slowly dissolve. Once the bone is gone, the implant will fall out.
What causes a dental implant to fail?
The main causes of dental implant failure are periimplantitis, bruxism, and poor oral hygiene. Let us look at how these three factors damage your implants.

First, periimplantitis is the most common cause of late failure. This is an infection that starts in the gums and moves into the bone. Bacteria build up on the implant crown and slide down under the gum line. The body tries to fight the bacteria, and this fight causes inflammation. The inflammation destroys the bone around the implant.
Second, bruxism is the medical word for grinding or clenching your teeth. Many people grind their teeth at night without knowing it. This grinding puts huge pressure on the implant. The constant pressure can break the porcelain crown, bend the abutment screw, or damage the bone holding the implant.
Third, poor oral hygiene allows plaque to build up. Plaque is a sticky film of bacteria. If you do not brush and floss, the plaque will turn into hard tartar. Only a dentist can remove tartar. The bacteria in tartar will cause infections and lead to implant failure.
How do you keep your dental implants healthy for decades?
You keep your dental implants healthy by following a strict daily cleaning routine and visiting your dentist regularly. To maintain your implants, you must perform these daily steps.
- Brush your teeth twice a day. Use a soft toothbrush and brush for two full minutes. Make sure to clean the area where the implant meets the gum line.
- Floss between your teeth every day. Use thick implant floss or a water flosser to clean the spaces under the crowns.
- Use an interdental brush. These tiny brushes slide between the teeth to clean hard to reach spots.
- Wear a night guard if you grind your teeth. A custom night guard from your dentist will absorb the pressure and protect your implants.
- Eat healthy foods. Avoid hard candies and sticky sweets that can damage the crowns.
- Do not smoke. Smoking reduces blood flow in your gums and makes it harder for your body to fight infections.
- Visit your dentist twice a year. The dentist will check the bone levels with x rays. They will also clean the parts of the implant you cannot reach.
How much does it cost to maintain dental implants in Australia?
Maintaining dental implants in Australia costs between 150 and 350 Australian dollars per year for basic cleanings, and up to 4000 Australian dollars for major crown repairs. Let us break down these costs.
A standard dental checkup and professional clean costs around 200 to 300 Australian dollars. During this visit, the hygienist cleans the implants with special plastic tools that do not scratch the titanium.
If the porcelain crown breaks or wears out after 20 years, a new crown costs between 2000 and 4000 Australian dollars.
For a full arch restoration like All on 4 dental implants, the maintenance costs can be higher. The acrylic teeth on a full bridge may wear down after 10 to 15 years. Replacing the teeth on a full bridge costs between 5000 and 12000 Australian dollars. The titanium screws inside the bone do not need replacement, so you do not have to pay for another surgery.
Frequently Asked Questions About Dental Implant Longevity
Do dental implants feel like natural teeth?
Yes, dental implants feel very similar to natural teeth. You can chew, bite, and speak without feeling any movement. The only difference is that implants do not have nerves, so you will not feel hot or cold temperatures through the implant.
Can you get gum disease with dental implants?
Yes, you can get gum disease around dental implants. This disease is called periimplantitis. It is caused by bacteria and plaque. You must brush and floss your implants just like natural teeth to prevent this disease.
What materials make up a dental implant?
A dental implant has three parts. First, the screw is made of medical grade titanium. Second, the abutment is a small connector made of titanium or zirconia. Third, the crown is the artificial tooth made of porcelain, zirconia, or metal alloy.
Will a dental implant last forever?
Yes, a dental implant screw can last forever if you keep your gums healthy and do not smoke. The titanium screw fuses with your bone and becomes a permanent part of your jaw. The crown on top will last 15 to 25 years before needing replacement.
Are dental implants safe?
Yes, dental implants are safe. Dentists have used titanium implants for over 50 years. The success rate is over 95 percent for the initial healing phase, making it one of the safest procedures in dentistry.
