Bone grafting is a common oral surgery procedure used to rebuild or strengthen areas of jawbone that have reduced in volume. It is most often recommended when planning dental implants, because an implant needs a stable amount of bone to sit in the correct position and remain supported over time. Although the idea of “adding bone” can sound daunting, treatment is carefully planned and is usually well tolerated, with clear aftercare to support healing.

What bone grafting is designed to achieve

Bone grafting, sometimes called bone augmentation, involves placing bone or a bone substitute into an area where the jawbone is too thin or has shrunk. The aim is to create a healthier foundation for future treatment, most commonly dental implant placement, and to help support the surrounding gum tissues.

Jawbone can reduce after:

• Tooth loss or tooth extraction (bone naturally shrinks when a tooth root is no longer present)
• Gum disease (periodontitis)
• Infection around a tooth
• Trauma or injury

Over time, reduced bone can make it harder or sometimes impossible to place an implant in a safe, stable, and aesthetically pleasing position without first rebuilding the area.

Who may benefit, and when it may not be suitable

Bone grafting may be suitable if:

• You are considering a dental implant and there is not enough bone volume to support it
• An implant can be placed, but extra bone is needed around it to improve long-term stability and gum health
• You have had a recent extraction and want to reduce the amount of natural shrinkage that can follow
• Implants are planned in the back of the upper jaw where the sinus reduces available bone height

It may be less suitable, or may need additional planning, if you:

• Smoke (healing is less predictable and complication rates are higher)
• Have uncontrolled diabetes or other medical conditions that affect healing
• Have untreated gum disease or poor oral hygiene (this can compromise graft and implant success)
• Are taking certain medicines that affect bone metabolism (your clinician will advise)

A graft can improve the chance of successful implant treatment, but it cannot guarantee a perfect cosmetic outcome in every case. Where bone and gum loss has been significant, the final tooth may look slightly longer at the gum line, and the gum shape may be harder to fully recreate.

Assessment and planning before treatment

A thorough implant assessment is essential. At your consultation, a clinician will:

• Review your medical history and current medications
• Examine your teeth, gums, bite, and the area being considered for an implant
• Assess gum health and screen for active infection or gum disease
• Take appropriate imaging, which may include a 3D scan (CBCT) to accurately measure bone height and thickness

This planning stage helps determine whether grafting is needed, which type is most appropriate, and whether it should be carried out at the same time as implant placement or as a separate staged procedure.

Sedation and pain control options can also be discussed during planning. Many patients have treatment comfortably with local anaesthetic alone, while others prefer sedation for anxiety or longer procedures.

Types of bone augmentation used in implant dentistry

The approach depends on how much bone is missing and where.

Minor bone augmentation (simultaneous grafting)

When bone loss is limited, grafting can sometimes be carried out at the same appointment as implant placement. Graft material is placed around the implant to increase local bone volume and support the gum tissues.

Staged bone grafting

If there is not enough bone to place an implant in the correct position, grafting may be performed first and the implant placed later, commonly after around 6 months of healing. This allows your natural bone to form and strengthen within the grafted area.

Sinus lift (upper back teeth)

In the back of the upper jaw, the sinus may limit available bone height. A sinus lift adds graft material below the sinus space to create enough height for implants. Depending on the starting bone level, this may be done at the same time as the implant or as a separate procedure several months beforehand.

Ridge preservation after extraction

After a tooth is removed, the socket and surrounding ridge can shrink. Ridge preservation involves placing graft material into the extraction socket to reduce shrinkage and help maintain the shape of the bone for future implant placement.

Materials used for bone grafting

Bone grafting typically involves two components:

Bone graft material (the “filler”)

Options may include:

• Your own bone (autograft): often collected from the same area or elsewhere in the mouth
• Processed animal-derived material (xenograft): widely used in dentistry for many years
• Synthetic material (alloplast): made in a laboratory
• Donor bone (allograft): may be used in certain staged grafts, such as a bone block, depending on clinical need and preference

The most suitable material depends on the size and location of the graft, your anatomy, and your treatment plan.

Barrier membrane

A protective membrane is often placed over the graft to stabilise it and help guide healing. Some membranes dissolve on their own (resorbable), while others may need a small follow-up procedure for removal (non-resorbable). Your clinician will explain which type is recommended and why.

What to expect on the day of the procedure

Bone grafting is carried out under local anaesthetic, with sedation available for suitable patients when needed. The steps vary by technique, but generally include:

• Numbing the area thoroughly
• Preparing the site and placing graft material where bone volume is needed
• Covering the graft with a membrane when indicated
• Closing the gum with stitches to protect the area during early healing

You will be given personalised aftercare instructions. If antibiotics or other medicines are prescribed, it is important to take them exactly as directed.

Healing timeline, recovery, and follow-up

Most people experience:

• Discomfort: often mild to moderate and typically improves over 4 to 5 days
• Swelling: usually peaks around day 2 to 3, then gradually reduces
• Bruising or stiffness: can occur, especially with larger grafts
• A small amount of bleeding: blood in saliva on the day of surgery can be normal

Time off work varies. Minor grafting may require little or no time away, while sinus lift or larger staged grafting can involve a longer recovery period.

Follow-up appointments are used to:

• Check healing and remove stitches if required
• Monitor gum health and plaque control
• Plan the next stage, such as implant placement once the graft has matured

For staged grafts, implant placement is commonly considered after several months, once imaging and clinical assessment confirm that bone has formed adequately.

Aftercare that supports the best result

Your clinician will tailor advice to your procedure, but common guidance includes:

Pain relief and swelling control

• Pain relief such as paracetamol or ibuprofen may be recommended if appropriate for you
• Swelling is expected and usually settles as healing progresses

Eating and daily activities

• A soft diet is usually advised for about a week, avoiding chewing directly on the surgical site
• Avoid hot drinks for at least 6 hours; cold drinks are typically fine
• Avoid strenuous exercise for the first few days and avoid swimming during early healing

Mouth care

• Do not rinse for at least 6 hours after surgery
• Warm saltwater mouthwashes are often started after the initial period, typically several times a day for a few days
• Brush the rest of your teeth as normal, but avoid brushing directly over the surgical site until advised
• If a mouthwash is recommended, use it as directed

Smoking and alcohol

• Smoking significantly increases the risk of complications and graft failure. Avoid smoking for at least two weeks after surgery, and ideally stop completely
• Avoid alcohol for about a week and avoid heavy drinking until healing is well established

Dentures

• If you wear a denture, you may be advised not to wear it for a period (often around two weeks) to avoid pressure on the graft. This is assessed individually.

Risks, limitations, and when to seek urgent advice

All surgical procedures carry some risks. Your clinician will discuss these with you in the context of your health and the planned technique.

Potential risks and complications can include:

• Infection, delayed healing, or graft material not integrating as intended
• Bleeding, swelling, bruising, or discomfort beyond what is expected
• Sinus-related symptoms after a sinus lift, such as congestion or a nosebleed in the first week
• The need for additional grafting if the desired bone volume is not achieved
• Aesthetic limitations in cases of significant bone and gum loss

Rarely, grafting in the lower jaw can be associated with nerve irritation or injury, leading to altered sensation or numbness in the lip, teeth, or tongue. If numbness persists longer than expected after anaesthetic, or if there is severe or unusual pain, urgent clinical advice is needed.

Your consultation journey and ongoing support

Bone grafting is only recommended after careful assessment and clear discussion of options. During your consultation, you can expect:

• A clear explanation of whether grafting is needed and why
• A personalised plan outlining timing, likely healing period, and the next steps toward implants if relevant
• Discussion of sedation options if you feel anxious about treatment
• Transparent review of expected benefits, realistic limitations, and potential risks

Our medical team remains involved throughout, from planning and imaging through to follow-up reviews and long-term maintenance advice. If you have concerns at any point during healing, you will be guided on what is normal, what is not, and how to access timely clinical support.
