The vast majority of dental implants are successful. However, as with any other surgical procedure, there are several internal and external factors that can cause failure of this treatment. If a problem does occur with your implant, contact your doctor immediately. Remember that for the most part, implant problems are minor and easy to resolve. A quick response now will allow for correction before you or your implant encounter serious problems. Problems with your implants can be avoided by planning a treatment schedule with your periodontist before the surgery, and by carefully following aftercare and oral hygiene instructions.

There are several reasons why a dental implant might fail. These include:

  • Failed osseointegration
  • Lack of bone volume or density
  • Infection
  • Nerve or tissue damage
  • Poor oral hygiene

Failed Osseointegration
Failed osseointegration simply means that the bone failed to fuse correctly with the implant. This causes the implant to be mobile and possibly even fall out. Failed osseointegration can be caused by incorrect positioning, insufficient bone density or volume, external forces or impacts, fractured implants, or even by a reaction to anesthesia.

Lack of Bone Density or Volume
Dental implants can also fail from a lack of bone density or volume. If you lack adequate bone height, width, or length, procedures such as a sinus lift or a bone graft can help but will add to your treatment time and the cost of the procedure. Patients who have been missing teeth for months or years will often require bone grafts before they can get implants. Implants may also protrude into the sinus cavity, causing the area to become infected or inflamed. X-ray and CT scans can easily detect this problem so that corrective surgery can be performed. Patients should inform their periodontist or oral surgeon of any sinus issues prior to the implant procedure.

Infection, or perio-implantitis, is a common complication for dental implants and is a form of gum disease. It can set it when bacteria is present during the surgery, or at any time after the surgery when good dental hygiene is not practiced. Infection involves inflammation of the gum or the bone around the implant, and it may not occur immediately. In most cases of infection, the implant must be removed.
Patients with diabetes, thin gums, smokers, and those with poor oral hygiene are at greater risk of developing infection. Smoking in particular significantly decreases the success rate of implants.

Nerve or Tissue Damage
If tissue around an implant is damaged, it can cause implant failure. When an implant is too close to the nerve, you may experience chronic pain, tingling, or numbness. As with other invasive surgeries, some tissue damage will occur during the procedure. Some bleeding and pain is expected for a couple of days following the surgery, but if the pain is extreme or the bleeding excessive, or if either of these conditions lasts longer than a few days, contact your periodontist immediately.

Poor Oral Hygiene
Dental implants have the potential to last as long as your natural teeth. However, they require the same care and attention as your original teeth. Brushing and flossing, as well as receiving regular dental exams and cleanings, will help to keep your teeth and your implants healthy. Failure to brush and floss increase your chances of developing gum disease, which contributes to dental implant failure. Smoking also greatly decreases the success rate of implants.

Other Reasons for Dental Implant Failure
Other, less common, causes of dental implant failure include foreign body rejection, allergic reactions, and the failure of the implant itself.

As with organ transplants, it is possible that a patient’s body will reject a dental implant as a foreign object and push it out. Patients may also experience an allergic or inflammatory response to the titanium alloy that the post is made of. Symptoms can range from itchiness to Chronic Fatigue Syndrome. Rarely, the implant itself may bend or break if subjected to excessive external forces, such as a sudden impact, or excessive pressure over time, such as grinding teeth.
