If you’re thinking about getting dental implants in Calgary, you’re probably wondering how long do dental implants last.
After all, this is a big decision that involves your time, money, and quality of life. The good news? Dental implants are built to last—and the research backs that up.
Here’s the short answer: More than 95% of dental implants still work after 10 years, and about 80% last 20 years or longer. Many people keep their dental implants for 25 to 30 years, and some even last a lifetime.
Let’s break down what affects how long your dental implants will last and what you can do to get the most years out of them.

What the Research Shows About Dental Implant Lifespan
Multiple studies tracking thousands of dental implants over many years show consistent success:
- At 5 years: 98.5% of dental implants are still working
- At 10 years: 90-95% remain functional
- At 20 years: 78-92% are still in place and working
Some Calgary patients have kept their dental implants for 25 to 30 years without any problems. These numbers come from a 2024 research review—the most complete look at 20-year implant results we have so far.
The titanium post that goes into your jawbone can genuinely last a lifetime. What usually needs replacing is the crown (the tooth-looking part on top), which typically lasts 10 to 15 years before normal wear requires an update.
Think of it like replacing tires on a car—the frame lasts, but parts that get constant use need refreshing.
How Dental Implants Stack Up Against Other Options
Understanding how different tooth replacement methods compare helps you plan for the long term.
Traditional dental bridges typically last 10 to 15 years, though some need replacement after just 5 to 7 years. These bridges require grinding down the healthy teeth next to your missing tooth, which creates weak points. If those support teeth get cavities or break, the whole bridge fails.
Traditional dentures have the shortest lifespan at 5 to 10 years. They need frequent adjustments because your jawbone gradually shrinks when you wear dentures (which actually speeds up the bone loss). Upper dentures usually last a bit longer than lower ones—about 10.3 years versus 8.6 years.
Implant-supported bridges and dentures offer a middle ground. The dental implants can last a lifetime while the bridge or denture portion needs replacement every 10 to 15 years.
Beyond just how long they last, dental implants give you better function. Traditional dentures reduce your biting force by 75% in the first five years and 97% after 15 years—severely limiting what you can eat.
Dental implants restore full chewing power and feel like natural teeth. They also prevent bone loss, keeping your facial structure from that sunken look some denture wearers develop.
Over 20 years, dental implants often cost less despite higher upfront prices. A single dental implant might cost $4,000 plus $1,500 for a crown replacement at year 15 (total: $5,500).
A bridge costing $3,500 would need replacement at year 12 (total: $7,000 or more). Traditional dentures look cheapest at first but need multiple replacements and adjustments that add up.
What Affects How Long Your Dental Implants Will Last
Your personal results depend on several factors—some you can control, others you can’t.
Smoking (The Biggest Risk Factor)
Smoking is the single worst thing for dental implant success. Smokers face a 140% higher risk of dental implant failure compared to non-smokers—11% failure rate versus just 5% for non-smokers.
Smoking restricts blood flow, slows healing, and increases infection risk around dental implants. Many Calgary dentists won’t place dental implants in active smokers because of these poor results.
The good news: quitting before your procedure significantly improves your chances.
Your Daily Cleaning Routine
Dental implants are less resistant to bacteria than natural teeth, making daily brushing and flossing critical. Poor cleaning leads to peri-implantitis—a destructive infection affecting the bone around your implant.
This happens in about 20% of all dental implants and 22% of dental implants in people who’ve had gum disease before. The infection spreads faster around implants than natural teeth, so small problems can quickly become big ones.
Regular professional cleanings every 6 months (or every 3 months if you’re high-risk) catch issues early when they’re still fixable.
Medical Conditions
Diabetes: Well-controlled diabetes shows minimal impact on dental implant success, but uncontrolled diabetes increases failure risk by 78%. Type 1 diabetes shows particularly poor results (347% higher risk). The key is control—patients with HbA1c levels below 7% achieve success rates similar to non-diabetics.
History of gum disease: This increases failure rates tenfold because the same bacteria that caused your gum disease can attack dental implant surfaces. You can still get dental implants, but you’ll need extra-careful cleaning and closer monitoring.
Teeth grinding (bruxism): Grinding creates excessive forces that prevent proper bone-implant fusion. Patients who grind their teeth show survival rates as low as 28-30% at 5 years without treatment—basically a 70% failure rate. Fortunately, wearing a custom nightguard protects your dental implants and prevents this problem.
Location in Your Mouth
Dental implants placed in your lower jaw perform better than those in your upper jaw—about 97% versus 95% success at 5 years.
The back upper jaw, particularly the molar area near your sinuses, is the most challenging spot due to lower bone density.
Your dentist may recommend bone grafting or sinus lift procedures to improve conditions in these areas.
Age and Medications
Patients 60 to 79 years old show 2.24 times higher failure risk than those under 40, though this often relates to health conditions that come with age rather than age itself.
Bisphosphonates (often prescribed for osteoporosis) increase failure risk by 65%. Oral bisphosphonates show relatively safe results (98.8% survival) while intravenous forms used for cancer treatment carry much higher risks. If you take these medications, discuss timing with both your doctor and dentist.
How to Make Your Dental Implants Last Decades
Following simple maintenance steps dramatically improves your odds of long-term success. Think of dental implant care as a few minutes daily that protects thousands of dollars and keeps your smile working well.
Daily Home Care
Brushing: Brush at least twice daily using a soft-bristled toothbrush (electric toothbrushes work particularly well) with gentle circular motions along the gumline for a full 2 minutes. Use non-abrasive toothpaste—highly abrasive formulas can scratch implant surfaces.
Flossing: Floss daily using unwaxed, soft floss with a gentle shoe-shine motion around the dental implant connector. For connected dental implants or bridges, you’ll need floss threaders to reach areas underneath.
Extra cleaning tools: Interdental brushes (small cone-shaped brushes) clean gaps between dental implants and hard-to-reach spots that regular brushing misses.
Water flossers (like Waterpik with a Plaque Seeker tip) are clinically 2 times more effective than string floss alone for dental implant care. Use your water flosser after regular flossing to flush out remaining debris and bacteria.
Daily alcohol-free antimicrobial mouthwash reduces bacteria and helps prevent infection.
Professional Care
Schedule cleanings and check-ups every 6 months minimum, or every 3 months if you smoke, have diabetes, or have had gum disease. These hour-long appointments should include:
- Specialized cleaning with plastic or carbon fiber instruments (not metal, which scratches titanium)
- X-rays to monitor bone levels
- Probing depth measurements
- Bite checks
- Examination for bleeding, swelling, or movement
Your dental team uses these visits to track changes and catch problems early.
Lifestyle Changes
If you smoke: Quitting is the single most impactful decision you can make—not just for implants but overall health.
If you grind your teeth: Wear your custom nightguard every night without exception.
Food choices: Avoid chewing ice, hard candies, and popcorn kernels, which can damage crowns. Sticky foods like taffy and caramel can dislodge restorations. Cut hard fruits and vegetables into small pieces rather than biting directly.
Nutrition: Maintain a balanced diet with adequate calcium and vitamin D to support bone health.
Diabetes management: Work with your healthcare team to keep your HbA1c below 7%.
What to Expect Over Time
Setting realistic expectations helps you plan and avoid surprises. While dental implants have excellent long-term success rates, they’re not maintenance-free.
Survival versus success: A dental implant that “survives” stays in your jaw and works but may have some bone loss or mild infection that needs watching.
A dental implant that “succeeds” meets stricter standards: no movement, minimal bone loss, no pain, and healthy surrounding tissues. About 10 to 15% more implants survive than strictly succeed, meaning some dental implants work fine but aren’t perfect.
Crown replacement: Your crown will likely need replacing before the dental implant itself. Most crowns last 10 to 15 years before needing replacement—a relatively simple procedure that doesn’t involve the bone or implant post. Budget for this eventual maintenance.
Possible complications: Peri-implantitis affects roughly 1 in 5 dental implants over time, with higher rates (22%) in people who’ve had gum disease. The key is catching and treating it early before significant bone loss happens.
Regular dental visits and home monitoring for warning signs allow you to act while problems are still manageable.
The Bottom Line for Calgary Patients
Dental implants offer the most durable tooth replacement solution, with strong evidence supporting 20+ year lifespans for most people.
Success rates exceeding 95% at 10 years and 80% at 20 years show the reliability of modern implant dentistry.
Your individual results depend heavily on your commitment to oral hygiene, smoking status, management of conditions like diabetes, and consistent professional care.
The patients who achieve decades of dental implant function follow daily brushing and flossing routines, use specialized tools like water flossers, see their dentist every 6 months, avoid smoking, and address problems quickly.
The dental implant itself can genuinely last a lifetime with proper care, though the crown will need replacement every 10 to 15 years due to normal wear.
Understanding these factors and maintenance requirements helps you make an informed decision and get the most from your investment in your smile and quality of life.
