Risks of dental implant

When an experienced dentist performs dental implant surgery, it is considered to be one of the safest and most predictable types of dental surgery. The implant provides strong support for teeth replacement and allows the appearance and function of the teeth to be restored, including the stimulation of bone regrowth underneath the tooth. However, several risks and complications are associated with dental implants and should be considered and minimized.

There are various factors that can affect the healing period following a dental implant, such as the quality of the bone and bone density at the site and the response of the tissue to the implant. In order to reduce the risks during the healing period following a dental implant, it is recommended to avoid applying excessive force to the implant as it heals.

Failure to Integrate

Primary implant stability, which refers to the stability of a dental implant directly following the procedure, is a significant factor for the integration of the implant into the bone. Insufficient primary stability can lead to failure of the implant within the initial weeks.

As the bone surrounding the implants begins to regrow and fuse with the dental implant, this supports the implant and provides secondary stability. This continues to strengthen as the fusion between the bone and implant increases, eventually leading to biological stability in the ideal scenario.

When the implant cannot be placed in the bone sufficiently to provide primary stability of the implant, there is an increased risk of failure of osseointegration. Prophylactic antibiotics are usually given prior to the implantation procedure, as this can help to reduce the risk of implant failure by a third.

During the procedure to place a dental implant in the jaw, some of the nearby anatomic structures are sometimes injured. This includes perforation of the maxillary sinus, inferior border, lingual plate, labial plate, inferior alveolar canal, or gingiva.If the maxillary sinus cavity is perforated by the implant, for example, this can lead to sinus problems and infections in the area in the future.

Infection is a considerable complication of dental implantation. Infection can occur in the affected area, presenting as an abscess, fistula, suppuration, inflammation or radiolucency. Additionally, it can also affect wider areas of the body to cause a systemic infection.

Although antibiotics are often given prior to the implantation procedure to help increase the chance of success of integration, they are unlikely to help reduce the risk of infection.

The Complications and Risks

There are also some other complications and risks linked to dental implants such as:

  • Nerve injury: this causes pain, numbness or paresthesia in the surrounding tissues (e.g. teeth, gums, lips or chin)
  • Tissue necrosis: the cells in the flap of tissue around the implant may die in approximately 1 in 20 cases.
  • Gingival recession: the gingiva next to the dental implant may recede to expose the metal abutment that holds the prosthetic in place.
  • Dehiscence: this failure of wound healing requires bone grafting
  • Excessive bleeding
  • Hyperplasia


In order to increase the likelihood of success of a dental implant, the mouth, gums and jaws should be in a healthy condition. There are some cases when a dental implant is contraindicated because the risk of failure is significantly higher, such as if the patient has:

  • Untreated tooth decay
  • Active periodontal disease
  • Uncontrolled diabetes
  • Diminished jawbone strength and thickness making it unable to support the implant

This is because people with these conditions have an increased risk of infection and implant failure, or it is more likely that the dental implantation will fail. Smokers should be encouraged to quit before they are offered a dental implant as quitting significantly increases the chances of success.

10 common question about dental implant risks

1What is the downside of dental implants?
What are the disadvantages of dental implants? Dental implants have several disadvantages compared to other methods of replacing lost teeth. ... A single implant may cost up to $5000 (and your insurance may not pay for it). However, a dental implant usually lasts longer than other tooth-replacement methods.
2What are the signs of dental implant failure?
If you have early or late-stage dental implant failure, signs of a complication include: difficulty chewing. gum inflammation. gum recession. increased swelling. loosening of an implant or a replaced tooth. severe pain or discomfort.
3How long do dental implants last?
A crown, however, is rated to last about 10 to 15 years before normal wear can cause the tooth to require replacement, although excellent dental hygiene could extend the life beyond 15 years. Mouth location is also a factor in the expected longevity of a dental implant.
4What are the negative effects of dental implants?
Infection at the implant site. Injury or damage to surrounding structures, such as other teeth or blood vessels. Nerve damage, which can cause pain, numbness or tingling in your natural teeth, gums, lips or chin. Sinus problems, when dental implants placed in the upper jaw protrude into one of your sinus cavities.
5Do dental implants last forever?
The short answer is that dental implants can last a lifetime. Here's the long answer. ... That isn't to say that dental implants work perfectly all the time, but recent studies have shown that dental implants have a 98% success rate (source). Many dentists conservatively estimate that implants will last about 25 years.
6What happens if dental implant fails?
In many early failures, the implant is quite loose. This is often due to poor healing ability of the patient, infection, lack of stability when it was placed (not firm enough in the bone) or most likely micro motion (too much movement of the implant during the healing process).
7Can Dental Implants Make You Sick?
Although titanium is generally considered safe, one study showed that patients had severe health problems after receiving dental implants. Medical issues included neurological problems, depression, and chronic fatigue syndrome. ... "If a patient has a hole in his mouth, his bite is going to be compromised.
8What is the success rate of dental implants?
90%–95% has been reported as the success rate of implants over the 10 years.[1] Although it has become the treatment of choice for most of the dentists, still, the complications arising from dental implant placement are the biggest challenge.
9How painful is it to get dental implants?
As the other answers describe, you should have minimal to no pain. ... However, people who undergo the procedure often say that having a tooth removed is more painful. A dental implant requires that your dentist make incisions in your gums. You will receive local anesthesia to numb your mouth during the procedure.
10Are antibiotics necessary after dental implant surgery?
Prophylactic antibiotic for each implant surgery is not mandatory. Antibiotics are however useful in preventing postoperative infections after implant placement. To achieve high long-term survival and success rates of dental implants, antibiotic prophylaxis is required.
