A dental implant is a small titanium screw placed in the jawbone that acts as an artificial tooth root. It fuses biologically with bone (osseointegration), so the crown fitted on top handles chewing forces like a natural tooth.
Why implants are the best option
| Implant | Bridge | Denture | |
|---|---|---|---|
| Cuts adjacent teeth? | No | Yes | No |
| Prevents bone loss? | Yes | No | No |
| Lifespan | 20+ years / lifetime | 10–15 years | 5–7 years |
| Chewing ability | Near natural | Good | Limited |
Treatment stages
- Assessment — X-ray, and CT if needed, to measure bone height and density.
- Placement — minor surgery under local anaesthesia, 45–90 minutes.
- Healing (3–6 months) — the implant integrates with bone. A temporary tooth can be provided.
- Abutment and crown — the connector is fitted and the permanent crown placed.
Who is suitable?
Generally healthy adults over 18 with adequate bone. Uncontrolled diabetes, heavy smoking, untreated gum disease and certain bone medications (bisphosphonates) raise the risk. Where bone is insufficient, grafting can make implants possible. A full assessment decides.
Aftercare
Implants do not decay, but the surrounding gum and bone can become inflamed (peri-implantitis) — the leading cause of implant failure. Brush twice daily, clean between teeth, avoid smoking, and attend check-ups at least twice a year.
