A bone graft for a tooth is a procedure that adds or regenerates bone in the jaw, usually in preparation for a dental implant or to stabilise the area after tooth loss.
When a tooth is lost or extracted, the jawbone in that area can begin to deteriorate due to lack of stimulation. Over time, this bone loss can compromise the surrounding teeth and make it difficult to place dental implants. A bone graft helps restore the structure and density of the jawbone, improving both oral function and aesthetics.
According to studies, around 30% of dental implant cases require some form of bone grafting to support long term success. While this might sound intimidating, modern bone grafting procedures are safe, effective and commonly carried out in specialist dental practices.
Why Would Someone Need A Bone Graft?
Bone grafting is most often needed when there is not enough healthy jawbone to support a dental implant. This could be due to:
- Tooth loss over a long period
- Gum disease (periodontitis)
- Injury or trauma
- Developmental defects
- Tooth extraction that led to bone resorption
Without adequate bone support, implants may fail or teeth may shift, causing issues with bite and facial appearance. A bone graft restores the foundation needed to keep everything in place.

How Does Bone Loss Happen After Tooth Loss?
The jawbone relies on stimulation from chewing forces to stay healthy and strong. When a tooth is lost, that area of the bone no longer receives stimulation, causing it to slowly resorb or shrink. This process begins soon after tooth loss and can result in as much as 25% bone loss in the first year alone.
If left untreated, the jaw can become visibly sunken or weak, making it more difficult to restore teeth with bridges, dentures or implants later on.
What Are The Different Types Of Bone Grafts?
There are several types of bone grafts, depending on the patient’s needs and the surgeon’s approach:
- Autograft: Bone is taken from the patient’s own body, often from the chin or hip.
- Allograft: Bone is sourced from a human donor and processed to ensure safety and compatibility.
- Xenograft: Bone comes from an animal source, typically bovine (cow), and is thoroughly sterilised.
- Alloplast: A synthetic material that mimics bone structure and supports regeneration.
Each type has its own advantages and your dental specialist will recommend the most suitable option based on the location and size of the graft needed.
What Happens During The Procedure?
The procedure is generally straightforward and can often be carried out under local anaesthetic. Here is what you can expect:
- The gum is gently opened to expose the area needing the graft.
- The chosen grafting material is placed and secured.
- A membrane may be added to protect the graft and encourage healing.
- The gum is stitched closed and allowed to heal over several months.
Some cases may allow for immediate grafting, where the bone graft is done at the same time as a tooth extraction or implant placement. In other cases, it is done in advance and allowed to integrate fully before moving to the next stage of treatment.
Is Recovery Painful?
Mild discomfort or swelling is common after a bone graft, but this can usually be managed with over-the-counter pain relief and proper aftercare. Most patients return to normal daily activities within a day or two. Your dental professional will provide specific instructions to support healing, including guidance on diet, oral hygiene and any medication.
Healing time varies depending on the type and size of the graft, but most bone grafts take between 3 to 6 months to fully integrate with the natural bone.

Are Bone Grafts Always Successful?
Bone grafting has a high success rate, particularly when performed by an experienced dental specialist. Success depends on several factors including general health, oral hygiene and whether the patient follows post-operative care instructions. Smoking, for instance, significantly lowers the success rate by interfering with blood flow and healing.
Once the graft has healed, it creates a strong foundation for dental implants or helps stabilise the jaw for other treatments.
Is Bone Grafting Safe?
Yes, bone grafting is a routine procedure in modern dentistry and is considered very safe when carried out by qualified professionals. Materials used are biocompatible and thoroughly screened to minimise any risk of rejection or infection. With today’s advanced techniques, patients can expect predictable outcomes and lasting results.
Where Can I Get a Bone Graft?
Bone grafting is typically offered at specialist dental or periodontal clinics. If you are considering dental implants or have been told you do not have enough bone, speak to a periodontist or oral surgeon about your options.
At The Perio Centre, our specialist team offers expertly planned bone grafting procedures using the latest techniques and materials, helping patients achieve stable and long term results for implants and oral rehabilitation.
Concluding Thoughts
A bone graft for a tooth is a safe and effective way to restore lost jawbone, especially if you are preparing for dental implants or recovering from tooth loss. With 30% of implant cases requiring grafting, it is a common and trusted part of advanced dental care. Whether due to gum disease, injury or age-related bone loss, bone grafting can help rebuild your smile’s foundation and restore your confidence in lasting dental solutions.
