Quick answer
You may need a bone graft before a dental implant if there is not enough healthy jawbone to securely support the implant. Bone loss can occur after a tooth has been missing for some time, following gum disease, infection, trauma, or previous tooth removal. A bone graft helps rebuild the area and create a stronger foundation for implant placement. However, not every patient needs one — your dentist will assess your bone levels using an examination and dental imaging before recommending treatment.
What is a dental bone graft?
A dental bone graft is a procedure used to increase or support the amount of bone in part of the jaw.
The graft material is placed in an area where more bone is required. It acts as a framework or scaffold that supports new bone formation as the area heals. Depending on the situation, graft material may come from your own bone or from processed human, animal-derived or synthetic materials. Your dentist should explain which material is being considered and why it is appropriate for you.
The goal is not simply to “fill a hole”. The aim is to create a stable foundation that allows the implant to be positioned appropriately and surrounded by sufficient supporting bone.
Why can bone disappear after a tooth is lost?
Your jawbone is living tissue that constantly remodels itself. When natural teeth are present, forces from biting and chewing are transferred through their roots into the surrounding bone. Once a tooth is removed, the bone in that area no longer receives the same stimulation.
Over time, some of this bone can shrink or resorb. The amount of bone loss varies considerably from person to person.
How do we know whether there is enough bone?
Your dentist begins with a clinical examination of your teeth, gums and bite. Dental X-rays are usually required, and in some implant cases a 3-dimensional CBCT scan may be recommended. This allows the clinician to assess the jaw in three dimensions and evaluate important structures around the proposed implant area.
The assessment may consider bone height, bone width, the shape of the ridge, nearby anatomy such as the maxillary sinus or important nerves, gum health, medical conditions, medicines and other factors that may influence healing.
Factors that can influence bone volume or healing include:
- how long the tooth has been missing
- previous infection around the tooth
- periodontal (gum) disease
- trauma
- the original shape and thickness of the jawbone
- previous extraction procedures
- smoking or vaping
- some medical conditions and medicines

When might I need a bone graft?
1. Bone loss after a tooth has been missing
When a tooth has been absent for months or years, the ridge may become narrower or shorter. If the remaining bone cannot adequately support an implant in the planned position, grafting may be recommended.
2. Bone loss from gum disease
Advanced periodontal disease can destroy some of the bone supporting the teeth. If an affected tooth is later removed and an implant is considered, additional bone reconstruction may sometimes be necessary.
3. Previous dental infection
Long-standing infection around a tooth root can damage surrounding bone. Following removal of the infected tooth and appropriate healing, grafting may be considered if the residual bone is insufficient for implant placement.
4. Naturally thin jawbone
Some people naturally have narrow bone around certain teeth, particularly in the front part of the mouth. Even if the tooth was removed recently, the anatomy may mean that additional bone is required.
5. Upper back teeth and the sinus
Above the upper premolar and molar teeth are the maxillary sinuses. After upper back teeth are lost, there may sometimes be inadequate vertical bone beneath the sinus for an implant. In selected cases, sinus augmentation may be considered.
6. Do I need bone graft when my teeth is being removed and a plan for implant is made?
May or may not – depend on infection present or not.
7. Do I need a bone graft if implant is placed at the same time?
May or may not – depend on infection present or not.

Can the bone graft and implant be done at the same time?
Sometimes, yes. If only a relatively small amount of additional bone is required and the implant can achieve adequate initial stability, grafting may sometimes be performed at the same appointment as implant placement.
However, when a larger defect exists, the clinician may recommend bone grafting first, followed by a healing period and then implant placement. There is no single timeline that applies to every patient.
What types of bone grafting are used?
Bone grafting is an umbrella term covering several techniques. The procedure selected depends on the size and location of the defect and the planned implant position.
Guided bone regeneration
Often used when a localised area around the planned implant needs additional bone. Graft material is placed in the deficient area and may be protected by a membrane while healing occurs.
Socket or ridge preservation
After a tooth is removed, graft material may sometimes be placed in the extraction site to help preserve the ridge dimensions. This can reduce some post-extraction collapse, although future grafting can still be required.
Ridge augmentation
If the jaw ridge has already become too thin or irregular, grafting may be used to increase its width or shape before implant treatment.
Block grafting
When substantially more bone is required, a block of bone may sometimes be used. This is more involved and may require a separate donor site.
Sinus augmentation
For implants in the upper back jaw, bone may sometimes need to be added beneath the maxillary sinus. Different sinus augmentation techniques are available depending on the amount of existing bone and the treatment plan.
Where does the graft material come from?
| Graft Type | What it means |
|---|---|
| Autograft | Bone taken from another area of your own body, often another part of the jaw for smaller grafts. |
| Allograft | Processed donor human bone from an appropriately regulated source. |
| Xenograft (most common) | Processed bone-derived material from another species, commonly bovine origin. |
| Synthetic graft material | Man-made materials designed to act as a scaffold for bone healing. |
What happens during the procedure?
The exact procedure depends on the type of graft required, but a typical minor graft may involve:
- Local anaesthetic is used to numb the treatment area.
- The gum is carefully opened to access the underlying bone.
- The implant site and bone defect are assessed.
- Graft material is placed where additional bone is required.
- A membrane may be positioned over the graft.
- The gum is repositioned and closed with sutures.
- The area is allowed to heal.
If the implant is being placed at the same appointment, implant placement takes place as part of the same surgical procedure. More extensive grafting can involve additional surgical steps.
Does a bone graft hurt?
The procedure itself is usually performed with appropriate anaesthesia, so the treatment area should be numb during surgery. Afterwards, some tenderness, swelling, bruising, minor bleeding or oozing and discomfort can occur. Your dentist will provide specific postoperative instructions and discuss appropriate pain relief for you.
How long does a bone graft take to heal?
There is no single healing period that applies to every bone graft. A smaller graft performed at the same time as implant placement may not necessarily add a separate long healing phase. A larger graft completed before implant placement may need several months to mature before the implant can be placed.
Healing time varies with the procedure, graft size, graft material, site, medical factors and individual healing response. Your dentist will monitor the site and decide when it is ready for the next stage.
Can a bone graft fail?
Yes. Like all surgical procedures, bone grafting cannot be guaranteed. Possible complications vary according to the procedure and site.
- infection
- wound opening
- graft or membrane exposure
- bleeding
- swelling or bruising
- pain
- insufficient new bone formation
- partial or complete loss of graft material
- delayed healing
- damage to nearby anatomical structures
- altered sensation or nerve injury in certain surgical areas
- sinus-related complications when grafting near the upper jaw sinus
- need for additional grafting or treatment
What can I do to help my graft heal?
Do not disturb the surgical site: Avoid repeatedly touching the area with your tongue or fingers.
Follow cleaning instructions carefully: You may temporarily be asked to modify brushing or cleaning around the surgical site.
Take prescribed or recommended medication as directed: Do not start or stop medicines unless advised by an appropriate healthcare professional.
Avoid smoking: Smoking can impair wound healing and increase treatment risks.
Follow dietary instructions: A softer diet may be recommended initially.
Attend review appointments: Your dentist needs to monitor the wound and graft healing.
When should I contact my dentist after bone grafting?
Some discomfort, swelling and bruising can be expected after surgery. Contact your dentist if you are concerned, particularly if you develop:
- increasing rather than improving pain
- significant swelling
- persistent or heavy bleeding
- fever or feeling unwell
- pus or an unpleasant taste associated with the surgical site
- wound opening
- graft material becoming substantially exposed
- persistent altered sensation
- symptoms that are worsening rather than gradually improving
For significant or rapidly worsening symptoms, urgent assessment may be required.
Do I have to have a bone graft?
Not necessarily. The decision depends on your treatment goals, anatomy and the alternatives available. Depending on your individual situation, alternatives may include modifying the planned implant approach, a dental bridge, a removable partial denture, another prosthetic solution or leaving the space untreated in selected circumstances. A specialist opinion may also be appropriate for more complex cases.
Dr Monica's advice
“When we discuss a bone graft, the goal is not to make implant treatment more complicated. The goal is to create the right foundation before we place the implant. Every patient is different, so we assess the bone, gums, bite and overall health carefully before deciding whether grafting is actually needed.”

Frequently Asked Questions
1. Does everyone need a bone graft before an implant?
No. Many patients have enough existing bone for implant placement without grafting.
2. How will my dentist know if I need one?
Your dentist will assess the implant area clinically and usually with X-rays. A CBCT scan may also be recommended when three-dimensional information is needed.
3. Can bone grafting be performed at the same time as the implant?
Sometimes. Small defects may sometimes be grafted during implant placement. Larger defects may require grafting and healing first.
4. How long will I need to wait after a bone graft?
It depends on the procedure. Some grafts are performed with the implant, while other cases require several months of healing before implant placement.
5. Where does the graft material come from?
It may come from your own bone or from processed human, animal-derived or synthetic materials. Your dentist should explain the material proposed for your treatment.
6. Is bone grafting safe?
Bone grafting is an established surgical technique, but it still carries risks including infection, graft exposure, pain, swelling, incomplete bone formation and graft failure.
7. Can smoking affect a bone graft?
Yes. Smoking can impair wound healing and is associated with a higher risk of complications and treatment failure.
8. What is a sinus lift?
A sinus lift is a particular grafting procedure used in some patients who need additional bone beneath the maxillary sinus in the upper back jaw.
9. Can I have an implant without having a recommended bone graft?
Sometimes another treatment plan may be possible, but it depends on the anatomy and treatment goals. Your dentist can discuss alternative implant approaches, bridges, dentures or other options.
10. Does grafted bone last permanently?
The purpose of grafting is for the site to heal and develop sufficient supporting bone. Bone remains a living tissue and can change over time, so long-term oral health and implant maintenance remain important.
