Bone Grafting for Dental Implants, Explained
Jawbone starts shrinking the day a tooth comes out. A bone graft rebuilds that foundation so an implant has something solid to hold onto — here's when you actually need one, what it feels like, and why the small graft now beats the big rebuild later.
Why bone melts away after tooth loss
Your jawbone is use-it-or-lose-it tissue. Every time you chew, the tooth root transmits force into the bone around it, and that stimulation is what tells the bone to stay dense. Pull the tooth and the signal stops — no root means no stimulation, and the body starts reabsorbing the bone it thinks you no longer need. The loss is fastest right away: about 25% of the ridge width disappears in the first year after an extraction, and it keeps shrinking slowly after that.
That matters because a dental implant is essentially a new root, and it needs enough bone to anchor into. Wait years after an extraction and the foundation may simply not be there anymore, which is where grafting comes in.
How we know you need one (hint: not guesswork)
Nobody can eyeball bone volume. At your free consult we take a 3D scan that measures the height and width of your ridge to the millimeter, shows exactly where nerves and sinuses sit, and answers the question definitively: enough bone, or not. If your bone is adequate, and for many patients it is — we'll tell you that, and no graft gets sold to you. If it's short, you'll see the scan yourself and the graft goes into your written quote with a price next to it.
Graft types, in plain English
| Graft type | When it's used | Our price |
|---|---|---|
| Socket preservation granules placed the day of extraction | At extraction — the cheap insurance that keeps your options open | $400–600 |
| Ridge augmentation rebuilding a ridge that already shrank | When the tooth has been gone for years | case-by-case |
| Sinus lift adding bone below the sinus floor | Upper molars, when the sinus sits low | from $800 |
Like everything here, those prices run about 20% below the typical Salem office, and every quote is itemized in writing before anything is scheduled.
What it actually feels like
Less dramatic than it sounds. Most grafts are done at the same visit as the extraction, under the same anesthetic: after the tooth comes out, sterile bone granules — think coarse sand — are packed into the socket and covered with a small protective membrane. It adds minutes to the appointment, not a second surgery, and recovery feels like a normal extraction. This isn't surgical-movie stuff; many patients don't realize the graft happened until we tell them it went well.
Healing: 3–4 months
The granules aren't the final product. They're scaffolding. Over 3–4 months your own bone grows through the granules and replaces them, leaving a solid, living ridge. A follow-up scan confirms the site is ready, and then the implant is placed. If you're mapping out the whole journey, our implant timeline guide shows where grafting fits in the full 3–6 month process.
The money angle: $500 now vs. $2,000+ later
Here's the math that makes socket preservation the easiest recommendation we make. A $400–600 graft placed the day the tooth comes out keeps the bone you already have. Skip it, let the ridge shrink for a few years, and rebuilding that same site later often costs $2,000 or more, plus 3–4 extra months of healing before an implant can even be placed. That's why we bring it up at extraction time, in writing, with a price — never sprung on you mid-surgery when you can't exactly discuss it.

Payment plans cover grafting like everything else.
