If you're considering dental implants, you're making a significant investment, and you want to know it'll last. Online, you'll see everything from "20 years" to "a lifetime" to the occasional horror story about implants failing early. So what's the honest picture?
At South Wilts Implant Centre, we think patients in Salisbury deserve a straight answer. Here's how long dental implants actually last, why they sometimes fail, and what you can do to make sure yours go the distance.
The Honest Answer
There are two parts to every dental implant, and they don't last the same amount of time:
- The implant itself - the titanium post placed in your jawbone. Designed to last for decades, and often a lifetime with proper care.
- The crown, bridge or fixed teeth on top - the visible part. Typically lasts 15 to 20 years or more, and may need occasional adjustments or repairs over time.
So when someone says "dental implants last a lifetime," they're usually talking about the implant itself. The crown or bridge on top is more like a car tyre: built to last a long time, but you'll likely replace it at some point. That's completely normal and doesn't mean the implant has failed.
What UK Success Rates Actually Show
UK studies consistently show dental implants have high success rates, with overall failure rates typically only around 2% to 3%. Properly cared for, implants outperform most other tooth replacement options over the long term.
The crucial phrase is "properly cared for." The small percentage of implants that do fail early tend to fail for specific, often preventable reasons, which brings us to the next question.
Why Dental Implants Sometimes Fail
When implants fail, it's usually down to one or more of these causes:
- Gum disease around the implant (peri-implantitis) - the single biggest risk. Gum infections that aren't caught and treated early are the leading cause of implant failure. Good oral hygiene and regular check-ups prevent most of this.
- Smoking - smokers have noticeably lower implant success rates because smoking slows healing and affects gum health. Quitting, or at least cutting back, before and after treatment makes a real difference.
- Poorly controlled diabetes - well-controlled diabetes is generally fine, but uncontrolled blood sugar levels make healing harder.
- Inadequate planning or placement - this is why who places your implants matters. Detailed 3D scans and careful planning prevent most technical failures.
- Bite issues or grinding - excessive force on implants (often from grinding at night) can cause long-term problems. A night guard fixes this.
The reassuring news is that most of these factors are manageable, whether by your clinician's planning or by your own care at home.
What You Can Do to Make Implants Last
Most of what keeps implants going strong is within your control:
- Clean around them properly - implants need the same care as natural teeth, plus interdental brushes or a water flosser to clean around the implant where a regular toothbrush can't reach.
- See the hygienist regularly - usually twice a year, more often if you've had gum disease in the past. This is the single biggest thing you can do to catch problems early.
- Come in for check-ups - we can spot early signs of trouble (inflammation, bite changes, loose crowns) long before they become serious.
- Don't smoke - the single most controllable lifestyle factor for implant longevity.
- Tell us about grinding - a simple night guard can prevent years of wear.
Warning Signs to Watch For
Implants don't usually fail overnight. If you notice any of these, get in touch:
- Gum around the implant looks red, swollen or bleeds when brushed
- The crown or fixed teeth feel loose or your bite feels different
- Persistent soreness or a bad taste from the implant area
- Receding gums around the implant
Most of these are treatable if caught early. The patients who lose implants are usually the ones who ignored symptoms for months.
FAQs
Can dental implants really last a lifetime?
The implant post itself often does, especially in healthy patients with good oral hygiene. The crown or bridge on top is more likely to need replacing once or twice over a lifetime.
How often should I have my implants checked?
We'd recommend a check-up and hygienist appointment at least every six months. If you've had gum disease, more often.
Do implants need replacing?
The titanium post generally doesn't. The crown or bridge on top may need replacement after 15 to 20 years. Occasional adjustments or small repairs are more common than full replacements.
What happens if an implant does fail?
It depends on why. Sometimes a failed implant can be replaced after healing; sometimes a different treatment plan is needed. We'd talk you through the options honestly.
