Bone Grafting Waterloo
Bone grafting is often closely associated with dental restorations such as bridge work and dental implants. In the majority of cases, the success of a restoration procedure can hinge on the height, depth, and width of the jawbone at the implant site. When the jawbone has receded or sustained significant damage, the implant(s) cannot be supported on this unstable foundation and bone grafting is usually recommended for the ensuing restoration.
There are several major factors that affect jaw bone volume:
- Periodontal Disease – Periodontal disease can affect and permanently damage the jaw bone that supports the teeth. Affected areas progressively worsen until the teeth become unstable.
- Tooth Extraction – Studies have shown that patients who have experienced a tooth extraction subsequently lose 40-60% of the bone surrounding the extraction site during the following three years. Loss of bone results in what is called a “bone defect”.
- Injuries and Infections – Dental injuries and other physical injuries resulting from a blow to the jaw can cause the bone to recede. Infections can also cause the jaw bone to recede in a similar way.
Reasons for Bone Grafts
Bone grafting is a highly successful procedure in most cases. It is also a preferable alternative to having missing teeth, diseased teeth, or tooth deformities. Bone grafting can increase the height or width of the jawbone and fill in voids and defects in the bone.
There are essentially two basic ways in which bone grafting can positively impact the health and stability of the teeth:
Jaw Stabilization – Bone grafting stabilizes and helps restore the jaw foundation for restorative or implant surgery. Deformities can also be corrected and the restructuring of the bone can provide added support.
Preservation – Bone grafting can be used to limit or prevent bone recession following a tooth extraction, periodontal disease, or other invasive processes.
Oral Examination
Initially, the dentist will thoroughly examine the affected area in order to assess the general condition of the teeth and gums. If periodontal disease is present or the adjacent teeth are in poor condition, these factors will be fully addressed before the bone grafting procedure can begin. The dentist will also recommend panoramic x-rays in order to assess the precise depth and width of the existing bone. On occasion, a CAT scan may be recommended to determine the bone condition. Depending on these results, the dentist may also anesthetize the area and explore into the gum in order to determine what kind and how much bone is required.
What Does Bone Grafting Involve?
There are several types of bone grafts. Your dentist will determine the right type for your particular condition.
Autogenous Bone Graft – Harvested from the patient’s own body (usually from the posterior part of the lower jaw or the chin). This method is usually preferred because it produces the most predictable results.
Allograft Bone Graft – Cadaver or synthetic bone is used in this type of graft.
Xenograft – Cow bone is used in this type of graft.
The bone grafting procedure can often take several months to complete. Bone is typically harvested from your own body (or on rare occasions obtained from a “bone bank”) and added to the affected site. This bone will fuse with the existing bone and the migration of cells will cause firm adhesion and cell growth. Supplementing the jaw with bone will result in greater bone mass to help support and anchor the implant(s).
During the surgery, the dentist will numb the grafting and extraction sites using local anesthetic. A small incision will be made to prepare the site for the new bone and it will be anchored into place. On occasion, a synthetic membrane may be used to cover the new bone. This membrane prevents soft tissue and bacterial invasions, and encourages new bone growth. The surgery does not require an overnight stay, and you will be provided with comprehensive instructions for your post-operative care. The dentist will prescribe medications to help manage infection, discomfort and swelling.

What to Expect From a Bone Grafting Procedure
Bone grafting rebuilds jaw bone that has been lost — usually from tooth extraction, gum disease, injury, or long-term denture wear. The procedure creates the foundation needed for dental implants and helps preserve the natural shape of the jaw and face. Bone grafting ranges from small same-day procedures done at the time of a tooth extraction to larger staged procedures done weeks or months in advance of implant placement.
On the day of surgery, the area is numbed with local anaesthetic. Sedation is available for larger grafts or for patients who would prefer it. The dentist or surgeon gently opens the gum to access the bone, places the graft material into the area where bone is needed, and may cover it with a membrane to protect the new bone as it forms. The gum is closed with sutures. The whole appointment usually takes 30 minutes to two hours depending on the size of the graft.
Healing is mostly invisible to the patient but very active under the gum. Over three to six months, your body integrates the graft material with existing bone, gradually forming new living jaw bone strong enough to support implants or stabilize the area around teeth. Follow-up x-rays track this process. Once integration is complete, implant placement (if planned) or further treatment can proceed.
Who Is a Candidate for Bone Grafting
Bone grafting is most often discussed in the context of dental implants, but it has other applications too. You may be a candidate when:
- A tooth has been or will be extracted and you may want an implant later — a graft at the time of extraction preserves the bone for future use
- An implant is planned but imaging shows the bone is too thin or too short to support it reliably
- Periodontal disease has caused bone loss around natural teeth and grafting may help stabilize them
- A sinus lift is needed because back upper jaw bone is too short under the sinus floor to hold an implant
- A denture is causing accelerating bone loss and grafting can slow it
- Trauma or a cyst removal has left a bony defect that needs to be filled
Active heavy smoking, uncontrolled diabetes, certain medications, and chemotherapy can affect healing and graft success; these are evaluated at consultation so the right plan can be built around your medical situation.
Recovery and Care After a Bone Graft
The first 48 hours involve mild to moderate swelling and discomfort, controlled with over-the-counter pain medication and cold compresses on the cheek. Avoid spitting forcefully, drinking through a straw, or smoking for the first week — these can dislodge the graft. Sleep with the head slightly elevated for the first few nights to reduce swelling.
Stick to soft, room-temperature foods for the first week: yogurt, smoothies, scrambled eggs, mashed potatoes. Avoid the surgical site when brushing for the first few days, using the prescribed antimicrobial rinse instead. Sutures are removed at the one to two-week follow-up. Most patients return to normal activities within a few days; vigorous exercise waits until the surgeon clears it.
Bone integration over the next three to six months is the most important phase. There is little for the patient to do during this time other than maintain good oral hygiene, attend follow-up visits, and protect the area from heavy chewing forces. Follow-up x-rays at three and six months confirm the graft has integrated before the next phase of treatment (implant placement, for example) is scheduled.
Cost and Insurance Coverage
Bone grafting cost depends on the type and amount of graft material, whether membranes or biologic agents are used, and the complexity of the site. A simple extraction socket graft costs less than a major sinus lift or ridge augmentation. Trillium follows the current Ontario Dental Association Suggested Fee Guide for grafting procedures, and we provide a written estimate at the planning visit.
Most private dental insurance plans cover a portion of bone grafting when it is medically necessary for tooth stability or future implant placement. Coverage levels vary; we submit a pre-determination to your insurer before treatment so the breakdown is clear before treatment starts.
Frequently Asked Questions
Where does the graft material come from?
Several sources are used: your own bone (autograft), donor human bone (allograft) processed through a regulated bone bank, animal-derived bone (xenograft), or synthetic materials. Each has trade-offs; your dentist will explain why a particular material is recommended for your situation.
Is bone grafting painful?
The procedure is done under local anaesthetic, so no pain during surgery. Post-operative discomfort is usually mild to moderate for the first few days and managed with over-the-counter medication. Larger grafts may involve more swelling and slightly longer recovery.
How long until I can get an implant after the graft?
Three to six months for most grafts. The exact wait depends on graft size, location, and how integration progresses. Skipping this wait risks implant failure, so your dentist will confirm with imaging before scheduling implant placement.
Will my body reject the graft?
True rejection is very rare. Donor and synthetic graft materials are processed to remove cells and proteins that would trigger an immune response. The body integrates the material as a scaffold for new bone to form around. Failures, when they happen, are usually due to infection or movement of the graft, not rejection.
Can I avoid bone grafting?
Sometimes. If imaging shows enough natural bone for an implant, no graft is needed. Implants can also be designed in different sizes or positions to work with available bone. In some cases, a fixed bridge or denture is chosen over implants specifically to avoid grafting. Your dentist discusses all options.
What if the graft does not take?
Graft failure is uncommon when patients follow aftercare instructions. If it does happen, the area heals and another graft can be attempted later, or alternatives to implants (bridges, dentures) are discussed.
