Dental implants have revolutionized the field of dentistry by offering a permanent, aesthetic solution to replace missing teeth. However, despite their high success rate, there is a possibility that the body may reject them.
Dental implant rejection can happen for various reasons, making it essential to understand the process, recognize the symptoms, and know what to do if it occurs.
At Clínica Dental Arpón y Quijada, we offer specialized dental implant services. Dr. Arpón is a specialist with extensive qualifications in oral surgery and implantology. In this article, our professionals respond your questions.
We’ll explain everything you need to know about dental implant rejection, from the initial signs to the timeframe in which the body may reject it.
Dental implant and process
A dental implant is a small titanium piece inserted into the jawbone or maxilla, designed to replace the root of a lost tooth. A dental crown is placed on this implant, simulating a natural tooth.
The dental implant procedure involves several steps, including a healing period called the osseointegration process, in which the bone bonds with the implant to form a strong base.
Local anesthesia is typically used to place or remove a dental implant, and maintaining good oral hygiene before, during, and after the procedure is essential.
What happens when the body rejects a dental implant?
Dental implant rejection occurs when the body fails to accept the implant as part of its bone structure. This means the body doesn’t recognize it as a dental component, preventing successful osseointegration.
Rejection can be caused by infections, lack of post-operative care, or underlying health issues in the patient.
Causes of dental implant rejection
Dental implant rejection can result from both internal and external factors. The most common causes include:
- Infection at the implant site. Poor hygiene or bacterial infection during healing can compromise implant success. Therefore, rigorous dental and oral hygiene is crucial.
- Lack of bone integration. If the bone does not properly bond with the implant, it can cause movement or rejection.
- Habits like smoking. Smoking reduces blood flow to the gums, slowing healing and increasing infection risk.
Symptoms of dental implant rejection
Signs of dental implant rejection appear after surgery or within the first months of recovery. Common symptoms include:
- Persistent pain. Ongoing pain that does not diminish over time may indicate a problem.
- Swelling and redness. While some swelling is normal after surgery, persistent or worsening inflammation may indicate infection.
- Loose implant. If the implant feels loose, it may mean the bone hasn’t properly integrated.
- Pus or discharge. Pus around the implant area is a clear sign of infection.
- Fever. Prolonged fever following dental surgery can signal an infection.
If the implant needs to be removed, with or without anesthesia, there are two options:
- Healing. The dental team will ensure the area is clean for proper healing, similar to a regular tooth extraction. The implant can be re-placed after three months.
- Bone regeneration with artificial bone. This option helps retain bone volume so that a new implant can be placed after a few months.
How long does it take for the body to reject a dental implant?
Implant rejection can occur at different times, depending on the underlying cause. The body may show signs of rejection within the first weeks or months after placement, typically within the healing period, which lasts between three and six months.
In rare cases, rejection may occur after several years, though this is uncommon.
What to do if the body rejects a dental implant
If you experience any of these symptoms or suspect your body is rejecting the implant, you should visit your dentist as soon as possible. The dentist will evaluate the situation, taking X-rays to check for bone integration issues or signs of infection.
In some cases, infection can be treated, or adjustments can be made to save the implant. If rejection is final, the implant will be removed, and alternative treatments planned. Success depends largely on the cause of rejection and prompt intervention.
How to prevent dental implant rejection
While it is not always possible to prevent implant rejection, certain measures can significantly reduce the risk. These include:
- Maintaining excellent oral hygiene. Brush and floss regularly to prevent infections.
- Following Dentist’s Instructions. After surgery, closely follow recommendations regarding diet, antibiotics, and physical activity.
- Avoiding tobacco. Quitting smoking before and after surgery improves the chances of success.
- Controlling underlying health conditions. Keeping conditions like diabetes under control.
Frequently asked questions about dental implant rejection
- Is dental implant rejection common?
Dental implant rejection is rare, with a success rate above 95%. However, it can occur, particularly if infections or pre-existing health issues are present.
- What are the first symptoms of implant rejection?
Initial symptoms include persistent pain, excessive swelling, pus discharge, and implant mobility.
- How long does it take for implant rejection to become noticeable?
Signs of rejection usually appear within the first three to six months, the period needed for the implant to integrate with the bone.
- What should I do if I think my implant is being rejected?
Visit your dentist as soon as possible. Depending on the cause, the problem can be addressed, or the implant removed if rejection is irreversible.
- Can I get another implant after rejection?
Yes, in most cases, a new implant can be placed. However, the cause of rejection must be treated before attempting another implant.
- Is dental implant rejection painful?
Most implant failures are painless. Patients may experience mobility in the implant without noticing it, especially during the healing phase in the first weeks. In rare cases, if failure occurs later, patients may notice pain, gum inflammation, and implant crown mobility.
