Infections after Dental Implant Surgery: Causes & Treatments


Tooth implant infection is a serious complication that can occur following dental implant surgery. While dental implants are generally considered a safe and effective way to replace missing teeth, infections can sometimes develop if proper oral hygiene is not maintained or if there are underlying health issues. If not promptly treated, these infections can lead to pain, swelling, and even the loss of the implant. Treatments for tooth implant infection may involve the use of antibiotics, mechanical debridement, surgery, and removal of the implant. 

This article will explore the causes, symptoms, and treatment options for tooth implant infection. We will also discuss how to prevent peri-implantitis from occurring in the first place and provide tips for maintaining good oral hygiene after dental implant surgery. By understanding the risks and taking proactive steps to prevent infection, patients can enjoy dental implants' benefits without worrying about complications.

Tooth implant infection is a serious complication that can occur following dental implant surgery.

What Is a Tooth Implant Infection?

A tooth implant infection, also known as peri-implantitis, occurs when bacteria invade the tissues surrounding a dental implant, leading to inflammation and potential damage to the bone supporting the implant. The severity of tooth implant infections can vary from mild gum discomfort to substantial degradation of the teeth and jawbone. If not addressed promptly, a tooth implant infection can cause bone loss and destabilize the implant.

Peri-implantitis can manifest shortly after the implant is restored with a dental crown or even years later. At times, there is little to no pain, so patients may not realize they have an infection.  

How Common Is Infection After Dental Implant?

Dental implant infections are relatively rare, with studies estimating the occurrence rate to be around 4-10% of all implant procedures. However, the risk of infection can be higher in patients with certain risk factors, such as poor oral hygiene, smoking, diabetes, and a compromised immune system.

What Can Cause Peri-implantitis?

Several factors can contribute to tooth implant infections, including:

  • Poor oral hygiene: Failing to practice good oral hygiene, such as brushing and flossing regularly, can lead to the buildup of plaque and bacteria around the implant, increasing the risk of peri-implantitis;
  • Smoking: Smoking has been associated with a higher risk of tooth implant infection due to its negative effects on the healing process and the body's immune response;
  • Pre-existing gum disease: Individuals with a history of gum disease (periodontitis) are at a higher risk of developing peri-implantitis, as the bacteria associated with gum disease can also affect the tissues around dental implants;
  • Systemic health conditions: Certain systemic health conditions, such as diabetes or autoimmune disorders, can compromise the body's ability to fight off infections and may increase the likelihood of peri-implantitis;
  • Poorly fitting prosthetic components: If the crown, bridge, or other prosthetic component attached to the implant does not fit properly, it can create spaces where bacteria can accumulate, leading to tooth inflammation and infection;
  • Trauma or excessive force: Excessive force or trauma to the implant site, such as from teeth grinding (bruxism) or improper bite alignment, can damage the surrounding tissues and increase the risk of peri-implantitis;
  • Dental cement: Residual dental cement on the implant creates a favorable environment for bacterial growth. This can eventually result in a tooth implant infection, leading to discomfort and potential complications;
  • Poor bone quality: Inadequate bone quality may not offer sufficient support for the implant, potentially leaving gaps that are susceptible to bacterial infiltration, increasing the risk of infection following tooth implant procedures;
  • Allergic reactions: In rare cases, some individuals may have allergic reactions to the materials used in the implant or prosthetic components, leading to inflammation and tissue damage.


What Are the Signs of an Infected Dental Implant?

Some common tooth implant infection symptoms can include:

  • Swollen and red gums around the implant site;
  • Pain or tenderness in the implant area;
  • Pus or discharge coming from the implant site;
  • Foul taste or odour in the mouth;
  • Fever or chills;
  • Difficulty chewing or biting;
  • Loose or wobbly dental implant;
  • Gum recession around the implant;
  • Persistent bad breath;
  • Visible threads on the implant;
  • Bleeding when brushing.


Signs of Dental Infection

How to Diagnose Tooth Implant Infection?

To diagnose a tooth implant infection, a dentist typically thoroughly examines the implant site. This may include taking X-rays to assess the bone and surrounding tissues. A sample of the fluid or tissue around the implant may also be taken for further analysis. Based on the findings of the examination and any additional tests, the dentist will be able to determine if an infection is present and develop a treatment plan accordingly.

How to Treat Tooth Implant Infection?

Common tooth implant infection treatment options are as follows:

Antibiotics 

Antibiotics are commonly prescribed to treat post-operative dental implant infections to help control the infection and prevent further complications. The choice of antibiotics and the duration of treatment will depend on the severity of the infection, the type of bacteria involved, and the patient's overall health. Some common antibiotics used to treat dental implant infections are amoxicillin, clindamycin, metronidazole, and ciprofloxacin.

It is essential to take antibiotics exactly as prescribed by your dentist, including completing the full course of treatment even if symptoms improve before the medication is finished. Failure to complete the full course of antibiotics can lead to antibiotic resistance and a recurrence of the tooth implant infection.

Antibiotics are commonly prescribed to treat post-operative dental implant infections.

Mechanical Cleaning

Mechanical cleaning involves physically removing the bacteria and debris from the infected implant site to help control the infection and promote healing. 

Ultrasonic devices and carbon fiber curettes are commonly employed for shallow mucosal pockets. Ultrasonic devices use high-frequency vibrations to break down plaque and bacteria on implant surfaces and pocket walls, while carbon fiber curettes delicately clean shallow pockets without harming the implant. On the other hand, deep pockets may be addressed using gentle scaling instruments or mechanical flossing to ensure thorough cleaning in hard-to-reach areas around the implant. Proper technique is crucial to avoid roughening the implant surface, which could lead to further complications.

In certain cases, locally administered antiseptics may be necessary to boost the efficacy of mechanical cleaning. These antiseptics play a crucial role in the treatment process by eradicating any remaining bacteria and preventing future infections. Combining mechanical cleaning techniques with antiseptic treatments can help ensure a successful resolution of dental implant infections while promoting long-term oral health and implant longevity.

Mechanical cleaning removes bacteria and debris from the infected implant site to control infection and aid healing.

Surgery

Surgery may be necessary to treat post-operative dental implant infections that have progressed significantly or are not responding to non-surgical treatments. Surgical intervention aims to remove the infected tissue, clean the implant site thoroughly, and address any underlying issues that may be contributing to the infection. 

The surgical treatment for dental implant infection typically involves several steps:

Firstly, an incision is made in the gum tissue surrounding the infected dental implant to access the affected area. This incision allows the dentist to visualize the extent of the infection and plan the appropriate treatment.

Once the area is accessed, the dentist carefully removes the infected implant from the bone and surrounding soft tissues. This removal is crucial to eliminate the source of the infection and allow for thorough cleaning of the area. Debridement, which involves removing any infected tissues, pus, or debris, is then performed to further aid in the healing process.

In cases where the infection has caused bone loss around the implant, bone grafting may be necessary to restore the bone volume and support the implant. This procedure helps stabilize the implant and improves its long-term success;

Antibiotic therapy may be prescribed following surgery to control the infection and prevent its spread.

Surgery may be necessary to treat post-operative dental implant infections.

Implant Removal

Implant removal is usually considered a last resort when all other treatment options have been exhausted. It is performed when the infected dental implants are causing complications such as significant bone loss or damage. 

The procedure involves surgically removing the infected implant from the jawbone. This allows the surrounding tissues to heal and the infection to be cleared.

After the implant removal, the area may need to be cleaned and debrided to ensure that all infected tissue is removed. Depending on the severity of the infection, additional treatments such as bone grafting or tissue regeneration may be necessary to restore the health of the jawbone and surrounding tissues.

Dental Implant Infection Home Remedies

It is important to note that treating a dental implant infection at home is not recommended, as infections around dental implants can be serious and may require professional intervention. 

However, some dental implant home remedies help manage symptoms and prevent the early dental implant infection from worsening before you can see your dentist. These include:

  • Maintain good oral hygiene: Continue to brush your teeth at least twice a day and floss daily, being gentle around the affected area to avoid further irritation;
  • Rinse with saltwater: Gently rinse your mouth with warm saltwater (1 teaspoon of salt in a glass of warm water) several times a day to help reduce inflammation and kill bacteria;
  • Use a cold compress: Applying a cold compress to the outside of your cheek near the affected area can help reduce swelling and alleviate discomfort;
  • Take over-the-counter pain relievers: If you are experiencing pain or discomfort, you can take over-the-counter pain relievers such as ibuprofen or acetaminophen as directed;
  • Avoid irritants: Avoid smoking, consuming alcohol, or eating hard or crunchy foods that may irritate the infected area.
