When Dental Implants Fail

DENTAL IMPLANTS ARE INCREDIBLE

Dental implants help you to maintain your chewing power, prevent damage to adjacent teeth, maintain bite stability, ensure you can eat a full range of foods, and remain and can chew properly and are a fixed tooth replacement when you’ve been unfortunate and lost a tooth. People are supposed to have fixed teeth, not gaps, and certainly not lumps of plastic that are removed and placed in a glass by the bed at night.

So what happens when dental implants fail? There is a complex interplay between your body and dental implant healing and maintenance. It’ll be easier to break things down to explain what can happen.

EARLY DENTAL IMPLANT FAILURE

Early dental implant failure is when your body rejects the implant, usually before the crown has been placed but anything up to a year after the crown has been secured onto the implant. Why does this happen? Well, it’s often very difficult to tell and frequently there is no reason for it. Studies show whenever an implant is placed, there is a 2% risk of the body rejecting the implant (my failure rate is half this, around 1%). Sometimes there is no obvious reason for the failure. In these instances we wait for the area to heal and place another implant; there is a 2% risk of failure each time an implant is placed. Other times, there may be a reason why the implant has failed (infection, smoking, poorly controlled diabetes, complexity of the procedure, experience of the surgeon, stress—this is why we take a medical history before placing an implant to ensure you are suitable for the procedure). If you experience an early failure, I may recommend a blood test with your GP to ensure there are no underlying health issues. If your treatment is more complex, I may request this blood test first.

LATE DENTAL IMPLANT FAILURE

Late dental implant failure is what happens if your implant fails after a year. Despite what you may have been told, implants do not last forever, and you can develop issues with them in the future. Why is this? Very simply, because your body is constantly dissolving and reforming the bone around your implant. This is natural and part of bone metabolism. The bone around your implant is completely remodelled every 6 months. You may have no problems for many, MANY years, and then if you were to become sick or put on certain medications, the bone reforming process can be interrupted. Implants can also develop gum disease-type infections, which can cause problems and in extreme cases lead to the loss of the implants.

But it’s not all doom and gloom! Despite this, dental implants are still one of the most successful treatment options in dentistry.

PREVENTING IMPLANT FAILURE

Preventing dental implant failure requires a strategic approach, where the knowledge and skill of your surgeon will play a HUGE role. I’m fortunate to be in a position where I ONLY place and restore dental implants. Many other dentists offer a range of services. Generating a healthy implant restoration and having it last a long time requires excellence in surgery, a deep understanding of implant systems, management of the gums, crown material choice, and even how the crown, which is to be secured to the implant, is finished and handled before it is fit. Your maintenance appointments with your general dentist and hygienist are also critical. We are aiming to stack the odds in our favour for longevity instead of having them stacked against us. What does all of this mean? This means dental implants CAN last a long time IF they are done correctly and maintained well. This can’t be done cheaply, which is why my fees are higher than average.

WHEN A DENTAL IMPLANT FAILS

Even after a long time, it can be possible to replace the implant. Sometimes it’s harder to do and may require more work, but it’s usually possible. An absolute must for me is doing everything I can NOW to try and get your implants lasting as long as possible. My premium implants are resistant to gum disease-type problems; the materials I use to make your teeth are very specific, and my lab knows if they don’t make the work perfectly, I’ll send it back to have it remade as many times as necessary (fortunately, I have a good lab, so this is rarely the case!).

I wish it were a black-and-white answer for you, but it’s much more subtle and complex than that. Which is exactly why I LOVE dental implants.
