Why might I need bone grafting before a dental implant?
What a 3D scan shows, how grafting changes timing and when another way to replace the tooth may be more proportionate.

An implant needs enough healthy bone in the planned position. Bone can shrink after extraction, infection or long-term tooth loss, but that does not mean every implant site needs grafting.
What the assessment considers
- Bone width and height on 3D imaging
- Nearby nerves and the sinus
- Gum thickness and the visible contour
- Medical and smoking risks
- Whether another implant position or treatment avoids grafting
How timing can change
A graft may be placed before the implant or at the same appointment, depending on the defect and planned stability. Healing can add months, and the sequence should be explained before treatment starts.
Alternatives remain valid
A bridge, denture or different implant approach may offer a better balance of intervention, timing and cost. Complex grafting may also be referred for specialist surgical care.
