Bone Grafting
Rebuilding the jawbone to make implants possible, preserve facial structure, and restore the foundation for healthy teeth.
Bone needs teeth to stay strong
Your jawbone is living tissue. Like every other bone in your body, it needs constant stimulation to maintain its density — and for the jaw, that stimulation comes from tooth roots. Every time you chew, the forces transmitted through your teeth tell the surrounding bone to stay strong.
When a tooth is lost — to extraction, decay, or injury — that stimulation stops. According to the National Institute of Dental and Craniofacial Research, the jawbone in that area can begin resorbing within just a few months, losing up to 25% of its width in the first year alone. Left long enough, the loss reshapes the face — giving the sunken appearance often seen with long-term tooth loss.
Bone grafting reverses this loss. By transplanting bone material into the deficient area, we trigger your body to grow new bone — restoring the foundation needed for implants, bridges, or simply preserving facial structure for the long term. For patients across Fremont, Cupertino, Milpitas, and the wider Bay Area, it's a routine, predictable procedure with a strong track record.
Common reasons we recommend grafting
Most patients learn they need a bone graft during planning for a dental implant. The implant requires a minimum bone volume to anchor securely — and when that volume isn't there, grafting becomes the first step that makes everything else possible.
But implants aren't the only reason for grafting. We also recommend it in several other situations, often years before an implant is even discussed.
Four common grafting procedures
Not all grafts are the same. The approach depends on where the bone is needed, how much is missing, and what the long-term plan is for the area. Most patients only need one of these four.
Socket Preservation
Placed immediately after a tooth extraction. Fills the empty socket with graft material to preserve bone for a future implant. Adds minimal time to the extraction visit.
Ridge Augmentation
Rebuilds the width or height of the jawbone ridge where teeth have been missing for some time. The standard pre-implant graft when bone has already started to resorb.
Sinus Lift
A specialized graft for the upper back jaw, where the sinus floor sits close to the molar roots. The sinus is gently lifted and bone added below it to support upper implants.
Block Graft
For significant bone deficiencies. A small block of bone (typically taken from another area of your jaw) is secured into the deficient site. Longer healing, but powerful results.
Where does the graft material come from?
Modern grafting uses one of four material sources depending on the case. All are extensively regulated and have decades of clinical use behind them. The American Association of Oral and Maxillofacial Surgeons considers all four to be safe and effective when used appropriately.
We'll discuss which option fits your case during your consultation. Most patients are surprised to learn that they don't need their own bone harvested — synthetic and processed materials work just as well for most situations.
Autograft
Bone harvested from elsewhere in your jaw or body. Highest integration rate. Reserved for larger reconstructions where the trade-off of a second surgical site is worthwhile.
Allograft
Sterilized human bone from tissue banks, FDA-regulated and screened. The most common graft material — predictable results, no second surgery needed.
Xenograft
Typically derived from purified bovine (cow) bone. Acts as a scaffold for your own bone to grow into. Long track record, especially for sinus lifts and ridge augmentation.
Synthetic
Bioactive ceramics and calcium-based compounds. No human or animal source. Increasingly common as the technology improves — fully resorbed and replaced with your own bone.
What grafting actually involves
A typical bone graft procedure takes about an hour, performed under local anesthesia with sedation options available. The healing time afterward is what makes the timeline long — the actual surgery is straightforward.
For socket preservation grafts done at the same time as a tooth extraction, the entire procedure adds only about 15 to 20 minutes to the extraction visit.
- Consultation & 3D imaging Cone-beam CT imaging maps your existing bone in 3D so we know exactly where graft material is needed and how much.
- Numb & access the area Local anesthetic is applied, then a small incision exposes the bone. Sedation is added if you've chosen it.
- Place the graft material Graft material is shaped into the deficient area. A protective membrane is placed over it to keep the gum tissue from interfering with bone growth.
- Close & heal The gum is sutured closed. The graft integrates with your existing bone over the next 3 to 6 months — that's where the real "growth" happens.
Bone grows slowly — and that's a feature
Unlike soft tissue (which heals in weeks), bone needs months to fully integrate a graft. The graft material acts as a scaffold that your body's own bone-forming cells gradually grow into and replace. By the time we place an implant, the grafted area looks and behaves like the bone that was always there.
The exact timeline depends on the graft type and your individual healing — but here's the general progression for a typical pre-implant graft.
Caring for the graft site
The first two weeks are the most important. After that, the graft is well-protected and your normal routine returns. Here's what to expect — and what to avoid.
First two weeks
- Soft foods only. Avoid chewing on the graft side entirely.
- No smoking or vaping. Nicotine significantly reduces graft success.
- Gentle saltwater rinses. Twice daily — no swishing, just hold and tilt.
- Mild swelling and bruising are normal for 3–5 days. Ice packs help.
- Avoid disturbing the area with your tongue, fingers, or toothbrush bristles directly.
Long-term healing
- Resume normal brushing around the graft area at 2 weeks (still gentle).
- Return for healing checks at scheduled intervals. We monitor with imaging.
- Avoid heavy chewing on the area for 3+ months.
- No high-impact sports without a mouthguard for the first month.
- Call us about increasing pain, swelling after day 5, fever, or any pieces of graft material coming loose.
Things patients often ask
Does bone grafting hurt?
Not during the procedure — you'll be fully numbed, with sedation options if you prefer. Afterward, most patients describe the discomfort as similar to a tooth extraction: mild to moderate soreness for 3 to 5 days, well-controlled with over-the-counter pain relievers. Prescription pain medication is used selectively for larger grafts.
How long does the whole process take?
The surgery itself takes about an hour (15–20 minutes for socket preservation done with an extraction). The healing and integration phase takes 3 to 6 months for most grafts before an implant can be placed. Larger block grafts may need 6 to 9 months.
Is the graft material safe?
Yes. All graft materials used in dentistry are FDA-regulated and have decades of clinical use. Allografts (donor bone) are sterilized and screened to medical-grade standards. Xenografts (bovine) are processed to remove all organic material. Synthetic materials contain no human or animal source. The AAOMS considers all four sources safe when properly indicated.
What if my graft fails?
Graft failures are uncommon but possible — typically caused by smoking, poor oral hygiene, untreated infection, or systemic conditions like uncontrolled diabetes. Most failed grafts can be redone successfully after a healing period. We'll discuss your individual risk factors during the consultation.
Does insurance cover bone grafting?
Coverage varies significantly by plan. Many PPO dental plans cover bone grafting when it's medically necessary (for example, to support a planned implant), while others classify it as elective. Some medical insurance plans also contribute when grafting follows trauma or treats a medical condition. We verify benefits and provide a detailed estimate before scheduling.
Can I get a graft and an implant at the same time?
Sometimes, yes. If the bone deficiency is small enough, we can place both in a single visit — the graft fills the space around the implant as it integrates. For larger deficiencies, we typically graft first, wait for healing, then place the implant. Your 3D imaging will tell us which approach works for your case.
Do I really need a graft? Can't I just get the implant?
If the bone volume is borderline, sometimes a smaller implant or a different angle can work without grafting. But forcing an implant into insufficient bone leads to failure — which costs more in the long run than grafting properly the first time. We'll show you the 3D imaging so you can see exactly what we're working with before recommending grafting.
