What is PRF, and why do we use it after extractions?

TLDR: PRF, or platelet-rich fibrin, is a small clot of concentrated healing cells spun from your own blood and placed directly into the socket after a tooth extraction. Research links it to better soft tissue healing, less post-operative pain, and a lower rate of dry socket. It is $250 per site, separate from the cost of the extraction, usually not covered by insurance, and it is not right for every extraction. We will tell you honestly when it is worth it. Call (623) 933-8410 to schedule your appointment.

When a tooth comes out, what happens next depends on one thing: the blood clot that forms in the empty socket. That clot protects the bone and nerve underneath and gives your body the scaffolding to rebuild. Our guide to what to expect from an extraction spends real time on protecting that clot, because when the clot fails, recovery gets painful fast.

PRF gives that clot a head start. Instead of hoping the socket fills well on its own, we deliberately place a clot there, one made from your own blood and packed with the cells that drive healing.

What is PRF, exactly?

PRF stands for platelet-rich fibrin. It is a small, gel-like clot made from a sample of your own blood: a natural fibrin mesh holding a dense concentration of platelets, white blood cells, and the growth factors your body uses to repair tissue.

PRF was first described by Dr. Joseph Choukroun and colleagues in France in the early 2000s, and it is classified as a second-generation platelet concentrate. Nothing is added: no anticoagulants, no chemical activators, no donor or animal material. It is your blood, spun down and put back where it can do the most good.

The fibrin mesh matters as much as the platelets. Rather than releasing everything at once, it holds the cells in place and releases growth factors gradually as it remodels, which is why PRF behaves differently in a healing socket than a plain clot.

How is PRF made during your appointment?

It happens in the same visit, and it adds roughly 15 to 20 minutes. The steps are straightforward:

• A small blood draw. We take a sample from your arm at the start of the appointment, the same kind of draw you would have at a routine physical. It is one or two small tubes.
• A spin in the centrifuge. The tubes spin for roughly 10 to 12 minutes, separating the blood by weight and concentrating platelets and white cells into a middle layer.
• Collecting the PRF. That middle layer comes out as a soft, yellowish clot. Depending on the socket, we use it as a plug or press it into a thin membrane.
• Placement. Once the tooth is out and the socket is clean, the PRF goes into the site, and we place stitches over it if the site needs them.

What does the research actually show?

The benefits with the clearest support are better soft tissue healing, less pain, and fewer cases of dry socket. A 2025 systematic review and meta-analysis of split-mouth randomized trials, covering 21 studies and 701 patients, found that PRF significantly improved soft tissue healing and reduced the incidence of alveolar osteitis, the clinical name for dry socket. Pain in the days after surgery was lower as well.

Split-mouth trials are unusually good evidence: each patient gets PRF on one side and standard care on the other, so the comparison happens inside one mouth.

Dry socket is the complication most patients have heard of. Its reported incidence runs from 1% to 5% after routine extractions and climbs to roughly 20% after surgical removal of impacted lower wisdom teeth. A systematic review and meta-analysis on preventing dry socket after lower wisdom tooth surgery pooled seven randomized trials covering 776 extraction sites and found PRF cut the risk by roughly two-thirds, with the authors rating the certainty of that finding as moderate. Worth knowing: that figure comes from surgical wisdom tooth cases, the highest-risk extractions there are, so it is not a number to expect from a simple front tooth removal. A separate meta-analysis on recovery after lower wisdom tooth surgery reported reductions in both pain and swelling.

What the research does not show

The limits matter as much as the benefits. In that same 2025 split-mouth analysis, PRF did not produce a statistically significant improvement in bone healing, and the authors describe the hard tissue findings as unsettled. Findings on trismus, the jaw stiffness that makes it hard to open wide, are mixed: the wisdom tooth recovery meta-analysis found no real difference, while others reported a small benefit. The 2025 split-mouth review could not measure trismus at all, because both sides of the jaw share a single mouth opening. The trials in this area also tend to be small, and their methods vary, which is why review authors keep asking for larger studies before treating PRF as a settled standard.

The honest summary: PRF has good support for comfort and soft tissue healing, and weaker, less consistent support for bone. It is no substitute for clean surgical technique or for following your aftercare. Individual results vary, and anyone promising you a specific outcome is overselling it.

Why did Dr. Kubik start using PRF for extractions?

Dr. Kubik did not adopt PRF because it was new. She adopted it because of what she kept seeing over years of extractions and follow-up visits. Sites treated with PRF tended to look calmer at the follow-up, and patients described an easier recovery than they had braced for.

That kind of observation is not a clinical trial, and she would be the first to say so. It became part of how we practice because the pattern she saw in the chair matched what the published research reports.

It also fits how we prefer to practice: your own biology instead of a manufactured material, and minutes rather than another appointment. That matters most for patients whose healing we watch closely, including many of the older adults we see across the West Valley, whose medications and health conditions can slow recovery.

When do we recommend PRF, and when do we skip it?

We recommend it when healing is likely to need help, and skip it when it will not change your outcome. A simple extraction in a healthy mouth usually heals well on its own, and we will say so rather than add a step you do not need.

PRF tends to be most useful when:

• The extraction is surgical or the tooth is impacted, both of which carry a meaningfully higher dry socket risk
• You plan to replace the tooth later with an implant, a bridge, or a partial denture, so the socket needs to heal as cleanly as possible
• You have had a slow or painful recovery from a previous extraction
• Your health history or medications give us reason to expect slower healing
• Several teeth are being removed at once

If you plan to replace the tooth, tell us before the extraction, not after. How the socket is treated on the day the tooth comes out shapes what the site looks like months later.

What does PRF cost?

PRF is $250 per site at our office, and per site means per socket. If three teeth come out at the same visit and we treat all three sockets, that is $750. Multi-tooth cases add up quickly, so your written estimate will show the full total before you decide. The fee covers the blood draw, the processing, and the placement, and it is separate from the cost of the extraction itself.

Most dental plans have no benefit category for PRF, so it is usually not covered and is paid at the time of service. Before you agree to anything, you will hear the number and what we expect it to do for you. We are also happy to go over the insurance we accept.

Some sockets also need a bone graft. That is a separate procedure, $500 to $900 per site for an extraction socket, and individual cases vary. A graft does a different job from PRF: grafting rebuilds missing bone volume, while PRF supports healing in the socket. The useful difference for your budget is that a graft may be covered by insurance, while PRF generally is not, so the two line items behave differently on an estimate. If Dr. Kubik expects you to need a graft, she will tell you before the extraction, not after.

What does recovery look like when PRF is used?

Largely the same as any extraction, with the same rules. Protect the site for the first 24 hours, keep biting on the gauze, and avoid smoking, straws, and forceful rinsing for several days. Soft foods for two to three days. PRF supports the clot. It does not do the work for you, so aftercare still matters.

What patients most often report is a quieter first week: less soreness than expected, and a socket further along at the follow-up. If anything feels wrong before then, call us.

Talking it through at Copper Sky Dental

If you have an extraction coming up, ask us whether PRF makes sense for your case. Dr. Kubik will look at your X-ray, your health history, and your plans for replacing the tooth, then give you a straight answer. If it is not worth it for you, she will say so.

If you have an extraction plan from another office and want a second read, our free second opinion is open to you, no obligation. Bring your X-rays and the written estimate.
