If you’ve been told you need a bone graft before an implant, it’s normal to have questions, and it’s normal to feel a bit put off by the idea. This page explains what a bone graft actually involves, why it’s sometimes necessary, and what to expect if you go ahead with one.
The short version: a bone graft rebuilds bone that’s been lost, usually after a tooth’s been missing for a while, so that an implant has enough solid bone to anchor into. It’s a well-established, routine part of implant dentistry, not a rare or experimental add-on.
Your jawbone needs the pressure of a tooth root to keep its shape and density. Once a tooth is gone, whether from extraction, gum disease, or injury, the bone underneath starts to shrink gradually, a process that continues for years if left unaddressed.
This matters specifically for implants because an implant needs a certain amount of solid bone around it to stay stable long-term. If too much bone has been lost, either in height or width, there isn’t enough to support an implant safely without adding some back first.
Common reasons a bone graft comes up include:
Not everyone needs a bone graft before an implant. It depends entirely on how much bone you have left, which is assessed with a scan before any treatment plan is confirmed.
There are several approaches, and which one applies depends on how much bone needs rebuilding and where.
Socket preservation is done immediately after an extraction, filling the socket with graft material to slow down the bone loss that would otherwise follow. It’s the simplest form of grafting and is often done as a precaution even when an implant isn’t planned right away.
Particulate (or granular) bone grafts use small particles of graft material to fill in minor bone defects, often combined with a protective membrane. This is the most common approach for moderate bone loss.
Block bone grafts use a solid piece of bone, sometimes taken from elsewhere in your own jaw, to rebuild a larger area where bone loss is more significant. These take longer to heal than particulate grafts.
Guided bone regeneration (GBR) combines graft material with a barrier membrane that keeps other tissue from growing into the area while new bone forms, used where the bone needs to regenerate in a specific shape.
Sinus lifts address the upper back jaw specifically, gently lifting the sinus membrane and packing graft material underneath to create enough height for an implant.
Graft material itself can come from your own bone (usually from elsewhere in the jaw), a donor source, or a synthetic substitute. We’ll talk through which is most appropriate for your case rather than defaulting to one option.
1. Assessment and scan. A 3D scan maps your existing bone volume precisely, showing exactly how much is missing and where.
2. Local anaesthetic. The procedure is done under local anaesthetic, sometimes with sedation available for more involved cases or anxious patients.
3. Placing the graft. The gum is opened, graft material is placed in the area needing rebuilding, and a membrane is added if the case calls for guided bone regeneration.
4. Closing up. The gum is closed with dissolvable stitches, and the graft is left undisturbed to integrate with your existing bone.
Most bone graft procedures take under 90 minutes, though this varies with the size and type of graft involved.
Initial healing, meaning the gum closing over and swelling settling, typically takes one to two weeks. Some tenderness, swelling, and mild bruising in the first few days is normal and manageable with over-the-counter painkillers, similar to what you’d expect after a tooth extraction.
Full integration of the graft with your existing bone, which is what actually needs to happen before an implant can be placed, takes considerably longer: usually three to six months, depending on the graft type and size. Larger block grafts sit at the longer end of that range.
During healing, stick to soft foods for the first week, avoid putting pressure on the graft site, and keep up with any prescribed rinses or antibiotics. Smoking significantly slows bone healing and increases the risk of graft failure, so it’s worth avoiding entirely during this period if you can.
This is usually the question people actually want answered. Once the graft has fully integrated, which your dentist confirms with a follow-up scan rather than guessing based on time alone, the implant can be placed. For most patients, that means somewhere between three and six months after the graft.
In some cases, particularly minor socket preservation grafts, an implant can be placed at the same time as the graft or only a few months later. Larger grafts, especially block grafts rebuilding significant bone loss, sit at the longer end. We’ll give you a realistic timeline specific to your scan, not a generic estimate.
Bone grafting is a well-established procedure, but it’s not without downsides worth knowing about upfront.
None of this makes bone grafting the wrong choice when it’s needed. It means going in with a realistic sense of the timeline and process, rather than expecting it to be a quick add-on step.
A bone graft isn’t always the only route to an implant when bone loss is a factor. Depending on how much bone you have and where, some alternatives exist.
Shorter or narrower implants can sometimes work in areas with mild bone loss without needing a graft at all, though this depends heavily on the specific site and forces involved.
All-on-4 and similar full-arch approaches are specifically designed to use the denser bone that often remains at the front of the jaw, sometimes avoiding the need for grafting even in patients who’ve lost significant bone elsewhere. Our All-on-4 page covers this in more depth.
Dentures remain a non-surgical option if grafting and implants aren’t the right fit for your situation, though they don’t address the underlying bone loss the way an implant does. Our dentures page explains the trade-offs.
We’ll only recommend a graft where it’s genuinely needed for the outcome you want, not as a default step in every implant case.
Bone grafting at Aqua Dental Clinic starts from £500. The exact cost depends on the type of graft, the amount of bone being rebuilt, and whether it’s combined with an implant procedure or done as a standalone step.
Our payment plans and membership plans may also apply. Full current pricing, including for implants themselves, is listed on our dental fees page. The only way to get an exact figure for your case is a scan and assessment.
Bone grafting only works as well as the planning behind it. Every graft we place starts with a detailed 3D scan, not a guess based on an X-ray or a quick look, so we know exactly how much bone is missing and which graft type actually addresses it.
We also won’t recommend a graft you don’t need. If your bone volume supports an implant without one, or a different implant approach like All-on-4 avoids the need for grafting altogether, we’ll say so. You can see the planning technology behind that on our technology page.
If dental anxiety is part of what’s holding you back from a procedure that sounds more involved than it is, our nervous patients page explains how we handle that.

The procedure itself is done under local anaesthetic, so you shouldn’t feel pain during it. Afterwards, expect swelling and tenderness similar to a tooth extraction, manageable with over-the-counter painkillers.
Initial healing takes one to two weeks. Full integration with your existing bone, needed before an implant can be placed, usually takes three to six months depending on the graft size and type.
Sometimes, for minor grafts like socket preservation. Larger grafts need to fully integrate first, which typically means a wait of several months before the implant is placed.
Not necessarily. It depends on how much bone you have left, which we assess with a 3D scan. Some patients have enough bone already, and some cases, like All-on-4, are specifically designed to work around limited bone.
Bone grafting is a well-established, routine procedure with a high success rate. Individual factors like smoking, overall health, and how well aftercare instructions are followed all affect the outcome.
Shorter or narrower implants can sometimes avoid the need for grafting in cases of mild bone loss, and full-arch approaches like All-on-4 are designed to use existing denser bone. Dentures remain a non-surgical alternative if implants aren’t the right fit.
Availability depends on clinical need and individual circumstances. We can talk through both NHS and private routes at a consultation.
Sedation options can be discussed and arranged in advance, particularly for larger grafts or anxious patients.
It can come from your own bone (often from elsewhere in the jaw), a donor source, or a synthetic substitute, depending on the type and size of graft needed. We’ll talk through which is most suitable for your case.
