Dental implants are the closest thing modern dentistry offers to replacing a natural tooth. But patients considering implants in Brisbane often ask the same question: how long will this last?
The short answer is that a well-placed, well-maintained implant can last decades. The longer answer involves understanding that an implant is a two-part system, and each part has a different expected lifespan. (If you have just had an implant placed, our implant aftercare guide covers the first 8 weeks of recovery.)
The implant body: 20 years and beyond
The implant itself is a small titanium post surgically placed into the jawbone. Once the bone grows around it and fuses with the surface (a process called osseointegration), the implant becomes a stable, permanent anchor.
Published longitudinal studies show survival rates above 95% at the 10-year mark, and many implants placed 30 or more years ago remain functional. Titanium is biocompatible, meaning it does not corrode or react with surrounding tissue. Once integrated, the implant body does not wear down the way a filling or crown does.
This does not mean every implant lasts forever. Failure can occur at any stage. But when placement is done well and the patient maintains their oral health, the implant body is designed to be a long-term solution.
The crown on top: 10 to 15 years typically
The visible part of the implant - the crown - is a separate component. Implant crowns are typically made from porcelain or zirconia and are subject to the same forces as natural teeth: chewing, grinding, temperature changes, and general wear.
Most implant crowns last 10 to 15 years. Some last longer. When a crown wears out or chips, it can usually be replaced without disturbing the implant underneath. This is one of the design advantages of the implant system: the foundation stays. Only the restoration needs updating.
If you grind your teeth at night, a night guard can protect the crown and extend its life considerably.
What affects how long your implant lasts
Several factors influence implant longevity. Some are within your control. Others depend on clinical decisions made at the planning stage.
Oral hygiene. This is the biggest factor. Plaque and bacteria accumulate around implants the same way they do around natural teeth. Without consistent brushing and interdental cleaning, you risk developing peri-implantitis - a condition where the gum and bone around the implant become inflamed and start to break down. It is the common cause of late implant failure and it is largely preventable.
Smoking. Smokers have higher implant failure rates at every stage: during healing, during the first year, and over the long term. Tobacco impairs blood flow, slows healing, and increases infection risk. If you smoke and are considering an implant, your clinician will discuss this with you directly. Quitting before surgery improves outcomes.
Teeth grinding (bruxism). Chronic grinding places excessive force on the implant crown and the bone around it. This can cause crown fractures and, in some cases, bone loss around the implant. If you grind, we will typically recommend a custom night guard or occlusal splint to protect the restoration.
Bone quality and quantity. The density and volume of your jawbone at the implant site affect how well the implant integrates and how stable it remains. In some cases, bone grafting is needed before or during placement to create a suitable foundation. Your clinician assesses this with 3D imaging during the planning phase.
Implant placement quality. Position, angle, depth, and the prosthetic design all matter. An implant placed in an unfavourable position may be harder to clean, subject to unusual forces, or unable to support the intended crown properly. This is why detailed planning - including CBCT scanning and sometimes digital treatment planning - is standard at Ivy.
Systemic health. Uncontrolled diabetes, certain autoimmune conditions, and medications that affect bone metabolism can all influence implant outcomes. These do not necessarily rule out implants, but they need to be factored into the treatment plan.
How to maintain your implant for the long term
An implant does not get cavities. But it still requires maintenance. The gum and bone around it are living tissue that respond to bacteria and inflammation just like the tissue around natural teeth.
Daily cleaning. Brush twice daily with a soft-bristled brush. Pay close attention to the gum line around the implant crown. Use interdental brushes or floss designed for implants to clean the areas a toothbrush cannot reach. Your hygienist can show you the most effective technique for your specific restoration.
Professional reviews. Six-monthly dental reviews and professional cleans are important. During these appointments, your clinician checks the implant, the crown, the surrounding gum tissue, and the bone level on x-ray. Small problems caught early - a loose screw, early gum inflammation, slight bone changes - are far easier to manage than advanced peri-implantitis.
Avoid hard or damaging habits. Do not use your implant crown to open bottles, crack nuts, or chew ice. These seem obvious, but they account for a surprising number of crown fractures across all dental restorations.
Wear a night guard if recommended. If you grind or clench, protecting the crown is one of the most cost-effective things you can do. A custom night guard from $650 is far cheaper than replacing a fractured implant crown.
What happens if something goes wrong
If the crown chips or fractures, it can usually be replaced. The implant body stays in place. Your clinician takes a new impression (or digital scan) and a lab-made crown is fitted to the existing implant.
If peri-implantitis develops, treatment depends on how advanced it is. Early-stage inflammation often responds to professional cleaning and improved home care. Advanced cases may require surgical intervention to clean the implant surface and regenerate lost bone. In rare cases where the implant has lost significant support, removal may be the only option.
This is why regular reviews matter. The earlier a problem is identified, the more options you have.
Implants compared to other options
Dental bridges typically last 7 to 15 years and require the adjacent teeth to be filed down for support. Dentures last 5 to 10 years and may need relining as the jawbone changes shape over time. Implants, with their 20+ year track record for the body and 10 to 15 years for the crown, offer the longest expected lifespan of any tooth replacement option.
The upfront cost of a dental implant is higher than a bridge or denture. But when you factor in longevity and the preservation of surrounding teeth and bone, the lifetime cost often compares favourably.
