A dental implant replaces the root of a missing tooth with a small titanium post, then supports a natural-looking crown on top. Here is how it works from start to finish.

What is a dental implant?
An implant has three parts: a post placed in the jawbone, an abutment that connects it, and a crown that looks and functions like a tooth. The post acts as an artificial root.
Titanium is used because it bonds well with bone, a process called osseointegration. Over a few months the bone grows around the post and holds it firmly in place.
The process, step by step
- Consultation: an examination, X-rays or a 3D scan to plan treatment.
- Placement: the post is placed in the jawbone under local anaesthetic.
- Healing: the bone integrates with the implant over several months.
- Abutment: a connector is attached to the post.
- Crown: a custom-made crown is fitted on top.
Timelines vary. Some people can have a temporary tooth fitted sooner, and some need extra steps first, such as a bone graft.
One tooth or several
A single implant replaces one tooth. A few implants can support a bridge across several missing teeth, and four to six can anchor a full arch, which can be more secure than conventional dentures.
Caring for an implant
An implant cannot decay, but the gums around it can still become inflamed. Brush and clean between it as you would a natural tooth, and keep up regular check-ups.
Frequently asked questions
Is getting an implant painful?
Placement is done under local anaesthetic. Soreness for a few days afterwards is common and usually manageable with standard pain relief.
How long do implants last?
With good care, the implant itself can last for many years, often decades. The crown may need replacing sooner because of wear.
Does a missing tooth have to be replaced?
Not always, but gaps can allow neighbouring teeth to drift and affect your bite. Your dentist can talk through the options.
