How To Know If Bone Graft Is Infected?

Request Appointment

"How to know if bone graft is infected?" It's a valid concern for anyone who has undergone or is considering bone graft surgery, whether for dental implants or orthopedic procedures. Bone grafting is a common procedure used in dental and orthopedic surgeries to repair bone defects, facilitate fracture healing, or support dental implants. While bone grafts are generally safe, there is a risk of infection, which leads to complications if not identified and treated promptly. It is important to recognize the signs and symptoms of an infected bone graft for timely treatment and to ensure the best possible outcomes.

Let us explore the key indicators of bone graft infections, factors that increase infection risks, preventive measures, and what steps to take if you have an infection. Understanding these aspects allows you to take proactive steps towards a smoother recovery journey.

What is a Bone Graft? 

Bone grafts are surgical procedures involving the transplantation of bone tissue to a specific area of the body. The primary goal is to stimulate bone growth or replace missing bone segments. These grafts can be sourced from different materials, including:


Bone tissue is taken from the patient's own body, often from another bone site.


Donor bone tissue is obtained from another human source, typically from tissue banks.


Synthetic materials are designed to mimic bone structure and promote bone growth.

What are the Signs and Symptoms of Bone Graft infection? 

The common signs and symptoms of Bone Graft infection are:

  1. Increased Pain: Persistent or worsening pain around the graft site, especially if it does not respond to pain medication, can indicate an underlying infection.
  2. Swelling and Redness: Localized swelling, redness, or warmth at the graft site are common signs of inflammation, which may signify an infection in progress.
  3. Fever: A fever, especially if accompanied by chills or sweats, suggests a systemic response to infection. It can indicate a more serious infection affecting the entire body.
  4. Pus or Drainage: Any discharge of pus or fluid from the surgical site is a clear indicator of infection and requires immediate medical attention.
  5. Delayed Healing: Signs of delayed healing at the graft site, such as persistent open wounds or lack of improvement over time, may indicate an underlying infection compromising the healing process.

Identifying these signs and symptoms is important because it helps catch any potential infection early on after a bone graft surgery. Getting medical help promptly can prevent complications and support a smoother recovery process.

Why would a Bone Graft procedure fail?

In most cases, dental bone grafts heal without issues, setting the stage for successful dental implants. This dependability is why so many opt for implants as a lasting solution for missing teeth. Yet, there are times when a bone graft doesn't achieve the desired outcome. Here are a few common reasons why:

Poor Home Care and Oral Hygiene 

Just like with any surgical procedure, taking good care of your bone graft site at home is crucial. Inadequate home care or neglecting proper oral hygiene can accumulate bacteria around the surgical area, increasing the risk of infection. Maintaining cleanliness around your surgical site is vital for optimal healing.

Dentist's lack of Experience 

Complex dental bone graft procedures are typically performed by oral surgeons, periodontists, or other specialized professionals who are experts in oral rehabilitation. They have the necessary skills, resources, and technology to ensure precise and minimally invasive treatment.

While some general dentists may offer bone grafts, especially in conjunction with procedures like tooth extractions for implant placement, a lack of experience in bone grafting can pose risks. Choosing an experienced and qualified dentist for a bone graft procedure is essential for a successful outcome and reduced complications.

Bone Tissue Contamination 

Before a bone grafting procedure, the bone graft material is carefully kept sterile. However, if the processed bone minerals get contaminated during preparation or placement, it can compromise the surgical site. This highlights the importance of having a periodontist or oral specialist with expertise in such procedures.

Active Oral Infection 

Do you suffer from periodontal disease? Persistent gum disease can pose risks to various dental procedures, including dental implants and bone grafts. Even though gum disease may have caused bone loss necessitating a graft, resolving the infection is crucial before proceeding with a bone graft. Periodontal treatments like deep cleanings and diligent home care can help alleviate inflammation within a few weeks, ensuring a healthier environment for successful grafting.

Intense Pain after a Bone Graft: 

Feeling intense pain after a bone graft isn't typical. Bones and bone graft materials don't have pain receptors. If you're experiencing significant pain, it might be due to a secondary infection. Over-the-counter pain relievers like Motrin are enough for minor discomfort after a bone graft. But if your pain worsens or you need stronger medication after a few days, there might be issues with the graft site that need attention.

Drainage or Swelling around Dental Bone Graft: 

After oral surgery, some swelling is normal, especially with procedures like tooth removal or extensive bone grafts. However, if you notice excessive swelling or discharge (pus) around the graft area, it could be a sign of bone graft failure. Alongside swollen and tender gums, any unusual discharge or swelling should prompt a call to your dentist in Los Angeles for immediate evaluation.

Soreness or Redness a Few Days After Surgery: 

While a bit of redness and soreness are expected after surgery, it should gradually improve. If redness persists or worsens over time, it might indicate infection or graft rejection. Sometimes, discomfort may also be due to a bone chip moving through the gum tissue, potentially indicating graft failure. It's essential to have any concerning symptoms checked by the dentist to monitor healing and address any underlying issues.

Steps to Take If Infection Is Suspected 

The following steps must be taken if a bone graft is infected:

  1. Consult Your Healthcare Provider: Contact your dentist, orthopedic surgeon, or healthcare provider immediately if you suspect a bone graft infection.
  2. Clinical Examination: Healthcare professionals will evaluate the graft site, possibly using imaging studies like X-rays or CT scans, to assess the infection.
  3. Antibiotic Treatment: Antibiotics are typically prescribed to treat bacterial infections based on the type and severity of the infection.
  4. Surgical Intervention: In severe cases or if the infection does not respond to antibiotics, surgical procedures such as debridement (removal of infected tissue) or graft removal may be necessary.

Preventive Measures for Bone Graft Infection 

To reduce the risk of bone graft infections, follow these preventive measures:

  • Adhere to post-operative care instructions provided by your healthcare provider.
  • Maintain good hygiene, especially around the surgical site.
  • Avoid smoking or using tobacco products, as they impair healing and increase infection risk.
  • Report any unusual symptoms or concerns to your healthcare provider promptly.

What our Patients say about us


My visit was incredible. I had my “All on Four” appliances cleaned, and it was a painless and thorough experience. Dr. Scott and all his staff are very friendly. During the cleaning, Mary was gentle and let me know everything she was doing and how it would feel. She gave me tips on how to clean my implants/appliances better and gave me a small brush to do the underside more effectively. Dr. Scott and Mary suggest cleanings take place every 3 months so I will be back in December.
