If your dentist has mentioned bone grafting for dental implants, your first reaction may well be concern; the phrase sounds significant, and the prospect of an additional procedure before the implant itself can feel daunting. The good news is that dental bone grafting is a well-established, predictable procedure that routinely allows patients who would otherwise lack sufficient bone to go ahead with implant treatment. At Fitzroy Dental Practice in Fitzrovia, we explain every stage of the process clearly at your consultation. Here is an overview of what it involves and why it matters.
Why does the jawbone matter so much for dental implants?
A dental implant is a titanium post that the dentist places directly into the jawbone, where it fuses with the surrounding bone in a process called osseointegration. This fusion is what gives the implant its extraordinary stability, effectively anchoring it as securely as a natural tooth root. For osseointegration to succeed, the bone at the implant site needs sufficient volume and density to surround the post on all sides.
When a tooth is lost or extracted, the jawbone beneath it begins to resorb, effectively shrinking, because the stimulation the tooth root provided disappears. This process begins within weeks of tooth loss and continues for months to years, gradually reducing the height and width of the available bone.
What causes bone loss in the jaw, and how quickly does it happen after tooth loss?
Bone loss after tooth extraction begins almost immediately; studies show measurable resorption within the first four to six weeks. Without the mechanical stimulation of a tooth root, the alveolar bone has no biological signal to maintain its volume. Approximately 25% of bone width is resorbed within the first year of tooth loss, with further gradual reduction thereafter. Gum disease, trauma, infection, and certain medical conditions can accelerate this process significantly.
How do I find out whether I have enough bone for a dental implant?
A three-dimensional cone beam CT (CBCT) scan gives your dentist or implant surgeon the most accurate picture of your current bone volume, height, width, and density at the proposed implant site. This scan allows precise treatment planning, including whether a graft is needed, what type, and approximately how much graft material the site requires. At Fitzroy, we review CBCT imaging at your implant consultation before discussing any treatment.
What exactly is a dental bone graft, and where does the graft material come from?
A dental bone graft places a bone substitute material into an area of deficient jawbone to encourage the body to lay down new, living bone around and through the graft. Over time, the graft material resorbs, and the patient’s own bone replaces it, leaving a stronger, denser ridge that can support an implant.
Graft materials fall into four categories: autograft (the patient’s own bone, harvested from another site in the mouth or body); allograft (processed donor bone from a human tissue bank); xenograft (bovine-derived bone mineral, the most widely used material in UK implant dentistry); and alloplast (synthetic calcium phosphate or hydroxyapatite materials). Each has its own profile of benefits and indications; your dentist will recommend the most appropriate option for your situation.
Is a bone graft taken from my own body, or can other materials be used?
In the majority of routine bone grafting cases for dental implants, xenografts or synthetic materials remove the need for harvesting the patient’s own bone, eliminating a second surgical site and simplifying the recovery. Autograft (the patient’s own bone) is reserved for cases requiring large-volume reconstruction, where the biological properties of live bone cells are considered advantageous. Your dentist will explain the rationale for the recommended material at your consultation.
What is the difference between a socket preservation graft and a larger jaw bone graft?
A socket preservation graft (also called ridge preservation) places graft material into the extraction socket immediately after tooth removal, before significant bone loss has occurred. This is a relatively simple, quick procedure that minimises future bone loss and often means a patient avoids the need for a larger graft later. A larger jaw bone graft addresses an existing area of bone deficiency; it is a more involved procedure that typically requires a longer healing period before implant placement.
What is vertical bone grafting, and when is it needed?
Most bone grafting for implants addresses width, restoring a ridge that has become too narrow in a horizontal direction. Vertical bone grafting rebuilds height, the dimension that has been reduced when the jawbone has resorbed significantly downward. This is required when the remaining bone height is insufficient for standard implant length, and it is technically more demanding than horizontal augmentation.
Vertical bone augmentation typically uses block grafts (solid pieces of bone fixed to the deficient site with titanium screws), guided bone regeneration (GBR) membranes, or distraction osteogenesis in more advanced cases. Outcomes are excellent in appropriate cases, but the procedure demands specialist surgical expertise and a longer planning and healing period.
How is vertical bone grafting different from a routine socket preservation graft?
Socket preservation is a straightforward preventive measure placed at the time of extraction and healing within three to four months. Vertical bone grafting reconstructs an existing deficiency, technically more complex, requiring a longer healing period of six to nine months or more, and typically referred to an oral surgeon with specific expertise in advanced implant reconstruction.
Does significant bone loss mean I cannot have a dental implant at all?
Not necessarily. Even patients with significant bone loss can often undergo implant treatment after appropriate grafting. The assessment determines the degree of bone loss, the most suitable graft approach, and whether the case falls within the scope of a general implant dentist or warrants specialist referral. Very advanced bone loss in some patients may make conventional implants impractical, but alternatives such as implant-retained dentures or shorter implants may still be options worth discussing.
How long does a bone graft take to heal before an implant can be placed?
Healing time depends entirely on the type and scale of the graft. The guide below reflects what most patients experience, though your dentist will give you a timeline specific to your situation:
- Socket preservation graft: 3–4 months before implant placement
- Minor lateral (horizontal) augmentation: 4–6 months
- Sinus lift (lateral approach): 6–9 months
- Major vertical augmentation or block graft: 6–12 months
During the healing phase, the grafted material integrates with the surrounding bone, a process that cannot be meaningfully accelerated. Patience at this stage is what makes the difference between a stable, long-lasting implant and one that risks failure.
How long does healing take for a small socket graft versus a larger jaw bone graft?
A socket preservation graft placed at the time of extraction typically allows implant placement within three to four months, making it the most straightforward route for patients who know they want an implant from the outset. A larger reconstructive graft placed to address an existing deficiency adds significant time to the overall treatment journey, usually six months or more before the implant stage begins.
How will my dentist confirm the graft has healed enough for an implant to be placed?
A repeat CBCT scan at the appropriate stage of healing allows the dentist to assess the volume and density of new bone at the grafted site. The scan confirms whether the site meets the clinical criteria for implant placement or whether additional healing time is needed. This imaging-led decision removes guesswork from the process and ensures the implant stage only proceeds when conditions are optimal.
What does the bone grafting procedure involve, and how uncomfortable is it?
Your dentist carries out the graft under local anaesthetic; you feel no pain during the procedure, though you will be aware of pressure and movement. The dentist makes a small incision in the gum to access the bone, places and shapes the graft material, covers it with a collagen membrane to protect the site during healing, and closes the gum with sutures. The appointment typically takes between 45 minutes and 90 minutes, depending on the extent of grafting required.
Will the bone graft procedure hurt, and how long does the appointment take?
Under local anaesthetic, the procedure causes no pain. Post-operatively, discomfort is manageable with ibuprofen and paracetamol for most patients; most describe it as comparable to a straightforward tooth extraction rather than a major surgical procedure. Swelling and mild bruising around the treated area are normal in the first few days and resolve within a week to ten days in most cases.
What should I expect during recovery from a bone graft?
The first 48–72 hours involve the most noticeable swelling and discomfort. From day three or four, most patients feel significantly more comfortable and return to desk-based work. Avoid strenuous exercise for at least a week. Gentle saltwater rinses from the following day keep the site clean; your dentist advises specifically on diet, cleaning around the site, and any activity restrictions at your discharge appointment.
How much does bone grafting cost for dental implants in London?
Bone graft cost in London varies considerably depending on the type and complexity of the procedure. As a general guide:
- Socket preservation graft: approximately £300–£600
- Minor lateral augmentation: approximately £500–£900
- Sinus lift: approximately £1,200–£2,500 per side
- Major vertical augmentation: £2,000–£4,000+ depending on complexity
The cost of two dental implants with bone grafting in London, therefore, depends on which graft type is needed. A combined treatment plan with written fees per stage is what Fitzroy provides at your consultation, so you can plan with full clarity.
Is bone grafting available on the NHS, or is it only offered privately?
NHS bone grafting for implants is not available in most circumstances; dental implants themselves sit outside routine NHS provision, and the grafting associated with them follows the same private pathway. Exceptions exist in hospital settings for specific clinical indications (such as trauma or congenital defects), but for the vast majority of patients seeking implants in London, bone grafting is a private treatment.
Does Fitzroy offer 0% finance for implant and bone graft treatment?
Yes. We offer 0% interest-free finance over 12 months with no deposit required, making it possible to spread the cost of combined bone grafting and implant treatment without a significant lump-sum payment. Speak to our reception team when booking your consultation for full details.

Frequently Asked Questions
What is a dental bone graft?
A dental bone graft places bone or bone substitute material into an area of the jaw that has lost volume, encouraging the body to produce new bone. In implant dentistry, grafting rebuilds the ridge to a sufficient size and density to support a titanium implant post.
How long does a bone graft take to heal before an implant?
Socket preservation grafts typically allow implant placement after three to four months. Larger grafts, including sinus lifts and vertical augmentation, require six to nine months or more of healing before the implant stage can begin.
How much does bone grafting cost for dental implants in London?
Socket preservation grafts typically cost £300–£600. Sinus lifts and larger augmentation procedures range from £1,200 to £4,000+ depending on complexity. Fitzroy provides itemised written treatment plans and offers 0% interest-free finance.
Does bone grafting hurt?
The procedure itself is pain-free under local anaesthetic. Post-operative discomfort similar to a straightforward extraction is manageable with ibuprofen and paracetamol for most patients and resolves within a few days.
Can I still have implants if I have significant bone loss?
In most cases, yes, appropriate bone grafting restores sufficient volume for implant placement. The degree of bone loss and the most suitable graft type will be assessed at your consultation, including whether specialist referral is appropriate for complex cases.
