PRF Therapy: Using Your Body's Own Healing Factors
Medically reviewed by Dr. Sergio Calleja, DDS, MPH — Board-Certified Oral & Maxillofacial Surgeon · Last reviewed 2026-02-05
PRF therapy uses a small sample of your own blood — spun in a centrifuge to concentrate the cells and proteins that drive healing — to help a surgical site recover. The concentrate is formed into a soft membrane or plug and placed directly where it is needed, such as an extraction socket or an implant site.
Because PRF comes entirely from you, it carries no risk of rejection or disease transmission. This guide explains, in plain language, what PRF actually is, how it differs from the older PRP, where the evidence is strong and where it is still developing, and why we present it as a helpful adjunct rather than a miracle cure.
What Is PRF, Exactly?
PRF stands for platelet-rich fibrin. Your blood contains platelets — tiny cells packed with growth factors, the natural signaling proteins that tell tissue to repair itself and build new bone and blood vessels. PRF is simply a way to concentrate those platelets and growth factors from your own blood and deliver them right to the surgical site.
The process is quick and happens chairside. We draw a small sample of blood, much like a routine lab test. The tubes go into a centrifuge — a machine that spins them fast for roughly ten minutes — which separates the blood into layers. The middle layer is a firm, gel-like clot rich in platelets and white cells, held together by fibrin, a natural scaffold protein. That clot is lifted out and gently pressed into a membrane or plug that the surgeon tucks into the site.
The full name of the version used in dentistry is L-PRF, or leukocyte- and platelet-rich fibrin. "Leukocyte" means white blood cells, which are part of your immune defense and add to the healing mix. Everything about PRF is autologous — a medical word meaning it comes from your own body — so nothing foreign is introduced.
Where PRF Is Used
Dr. Calleja may use PRF as an adjunct — an add-on that supports the main procedure — in situations such as:
- Tooth extraction sockets, where it may help the site heal and, evidence suggests, reduce the risk of a painful dry socket
- Bone grafting, where PRF is mixed with graft material to help hold it together and support new bone formation
- Dental implant sites, to support the soft tissue and bone around a newly placed implant
- Sinus procedures done before upper-jaw implants
- Ridge preservation — filling a socket after extraction to help maintain bone shape for a future implant or denture
- Cases where a patient wants to draw on their own biology to support recovery
Why Patients Consider PRF
- 100% from your own blood — no rejection and no disease-transmission risk
- No chemical additives, unlike some older techniques
- Growth factors are released gradually as the fibrin scaffold breaks down
- Prepared chairside during the same visit — no extra appointment
- Adds only a simple blood draw to your existing procedure
- May support healing of the main procedure without changing your recovery routine
The Chairside Process, and How PRF Differs From PRP
PRF adds just a few minutes to your existing procedure and requires nothing special from you beforehand. Here is how it works, step by step.
- Blood draw: A small sample of your blood is drawn from your arm, exactly like a routine lab test.
- Centrifuge: The tubes spin in the centrifuge for about ten minutes, separating the blood so the platelet- and fibrin-rich layer forms.
- Preparation: The surgeon lifts out that clot and presses it into a thin membrane or shapes it into a plug.
- Placement: The PRF is set directly into your extraction socket, graft, or implant site during the same surgery, then the area is closed as usual.
Risks and an Honest Look at the Evidence
The risks of PRF are essentially the risks of a routine blood draw: brief discomfort, a small bruise, or lightheadedness in people sensitive to needles. Because the material is 100% your own blood with no additives, there is no risk of allergic reaction to the concentrate, no rejection, and no chance of catching a disease from a donor. It adds no separate recovery of its own.
On effectiveness, we believe in giving you the honest picture. PRF is widely used and biologically sensible, and for some uses the research is encouraging. In tooth extraction — especially lower wisdom teeth — several studies report less post-operative pain and a lower rate of dry socket (the painful condition when a socket loses its protective clot) when PRF is placed. That is a genuinely promising signal.
At the same time, the evidence quality varies by application, and study results are not uniform. Some trials show clear benefit, others show little measurable difference, and long-term data for uses like implant survival in PRF-treated sites is still limited. For that reason Dr. Calleja presents PRF as a helpful adjunct that may support your body's own healing — not a guaranteed outcome and not a substitute for sound surgical technique. He will tell you candidly whether the evidence supports using it in your specific case.
Recovery With PRF
PRF does not add a recovery period of its own — its whole purpose is to support the healing of the procedure it accompanies. You follow the same aftercare instructions you would for your extraction, graft, or implant, whatever that main procedure requires.
The one small extra is the blood-draw site on your arm, which may show a minor bruise for a day or two and needs no special care. Where PRF is placed in the mouth, it is gradually absorbed by your body over the following days as the fibrin scaffold releases its growth factors and dissolves — there is nothing to remove.
As always, follow your post-operative instructions closely: keep the site clean, eat soft foods at first, and protect any clot in an extraction socket. Call the office for fever, bleeding that will not stop with gentle pressure, or worsening pain or swelling after the first few days.
Terms You'll Hear
Doctors and patients often use different words for the same thing. Here's how they connect:
- "blood platelet healing treatment" = PRF (platelet-rich fibrin)
- Concentrating the healing platelets from your own blood into a membrane placed at the surgical site.
- "the healing membrane or plug" = L-PRF membrane / clot
- The gel-like layer of platelets, white cells, and fibrin lifted from the spun blood and placed in the wound.
- "the spinning machine" = centrifuge
- A device that spins the blood tubes fast for about ten minutes to separate out the platelet-rich layer.
- "natural repair proteins" = growth factors
- Signaling proteins in platelets that tell tissue to repair itself and build new bone and blood vessels.
- "from your own body" = autologous
- Made entirely from your own blood, so there is no rejection and no disease-transmission risk.
- "older platelet technique" = PRP (platelet-rich plasma)
- The first-generation method that uses additives and releases growth factors quickly; PRF is the additive-free second generation.
Frequently Asked Questions
What is PRF therapy?
PRF stands for platelet-rich fibrin. A small sample of your own blood is spun in a centrifuge to concentrate its platelets and growth factors — the natural proteins that drive healing — into a soft membrane or plug. The surgeon places that concentrate at your surgical site, such as an extraction socket or implant site, to support recovery. It is used as an add-on to the main procedure.
How is PRF different from PRP?
PRP (platelet-rich plasma) is the older, first-generation technique; PRF is considered the second generation. PRP is prepared with an added anticoagulant and sometimes other chemicals, and it releases its growth factors quickly. PRF uses no additives at all — it relies only on your own blood clotting naturally into a fibrin scaffold, which then releases growth factors slowly over a longer period. That slower, additive-free release is the main reason many surgeons now prefer PRF.
Is PRF safe?
PRF is very safe because it is 100% your own blood with nothing added. There is no risk of rejection, no risk of an allergic reaction to the material, and no chance of disease transmission from a donor. The only real risks are those of the blood draw itself — a brief pinch, a possible small bruise, or lightheadedness for people sensitive to needles.
Does PRF really work, or is it hype?
The honest answer is that PRF is a promising, widely used adjunct — not a miracle. For some uses, such as reducing pain and dry-socket risk after tooth extraction, the research is encouraging. For others, the evidence is mixed or still developing, and results vary between studies. Dr. Calleja uses PRF where it makes biological sense and will tell you candidly how strong the evidence is for your particular procedure.
Can PRF prevent dry socket?
Several studies, especially after lower wisdom-tooth removal, report less pain and a lower rate of dry socket when PRF is placed in the socket. That is a genuinely promising finding, though not every study agrees and PRF is not a guarantee. It is one tool that may lower the risk alongside good technique and careful aftercare.
How long does the PRF process take?
It adds only a few minutes to your existing appointment. We draw a small blood sample, spin it in the centrifuge for about ten minutes while your procedure is underway, then place the finished PRF at the surgical site during the same visit. No separate appointment is needed.
Does PRF hurt or make recovery longer?
No. PRF adds no recovery of its own — it is there to help the main procedure heal. The only extra is a routine blood draw from your arm, which may leave a small bruise. You follow the same aftercare instructions as you would for your extraction, graft, or implant.
Will my insurance cover PRF?
Coverage varies. PRF is often considered part of the surgical procedure or an add-on that may not be separately covered by every plan. Our team will explain any cost clearly before your surgery so there are no surprises.
