How dental implants work – explained in plain English

An implant replaces the root of a missing tooth, not just the part you see. This guide shows what goes where, why your jawbone matters and how treatment fits around a busy working week at 223 Waterloo Road.

The key facts

  • Three parts: post, abutment and crown
  • The post bonds with your jawbone over a few months
  • Neighbouring teeth are not filed down
  • Planned with a 3D scan taken in our own practice
  • Written, itemised quote before treatment

The short version

A dental implant is a small, screw-shaped post that sits in your jawbone where a tooth root used to be. Over the following months, bone grows tightly against its surface and holds it firm. A connector called an abutment is then attached, and a crown – the part you see – is fixed on top. Together they behave like a tooth with its own root, so you can bite, smile and brush in the usual way.

A natural tooth and an implant, side by side

Your own teeth are held in the jaw by their roots. An implant copies that design, with a titanium post doing the job of the root.

The three parts of an implant

The implant post

A threaded post, only a few millimetres wide, placed in the jawbone. Its surface is designed so that bone can grow onto it. Once settled, it acts as the new root.

The abutment

A small connector that fixes into the post and rises through the gum. It gives the crown a firm, accurately shaped base and links what is in the bone with what is in your mouth.

The crown

The visible tooth, made in a dental laboratory to match the shade and shape of your own teeth. Depending on the design, it is screwed or cemented onto the abutment.

What they are made of

Most implant posts are titanium or a titanium alloy, a metal with a long history in medicine and dentistry. Some systems use other materials, such as ceramic. Your dentist explains the system they recommend and why.

Why your jawbone matters

An implant is only as steady as the bone around it. After placement, your body gradually lays down new bone onto the implant's surface – a process called osseointegration. It takes weeks to months, which is why the final crown is not fitted straight away. Bone also needs work to do: when a tooth is lost, the bone that held it slowly shrinks because it is no longer being used. An implant passes biting forces back into the jaw, which helps to keep that bone in use.

Over weeks and months, new bone grows into the space around the implant until it hugs the threads. Only then is the implant ready to carry a crown. Illustration only.

If your 3D scan shows there is not enough bone, we explain the options, which may include grafting, and include it in your written quote.

From first visit to final crown

  1. Consultation (£75)
    We examine the gap and explain your options and costs. The fee is taken off your treatment if you go ahead.
  2. CBCT 3D scan
    Taken in our own practice, so there is no extra trip elsewhere. It shows the height and width of your bone.
  3. Written plan and quote
    Every stage is itemised before you decide.
  4. Implant placement
    Carried out under local anaesthetic. Many people go back to work the next day; some tenderness for a few days is normal.
  5. Healing time
    Usually a few months while the bone bonds with the implant. For a front tooth, a temporary is normally planned so you are not left with a gap.
  6. Abutment and crown
    Once the implant is stable, your crown is made and fitted, and we show you how to keep it clean.

Fitting treatment around your working day

Most visits are short. We are a few minutes' walk from Waterloo station, so many appointments can sit before work or over a long lunch. We map out the sequence of visits with you at the start, so you know in advance which day might need a little time off afterwards.

What an implant can replace

One tooth

A single implant and crown fills one gap without touching the teeth either side.

Several teeth in a row

An implant bridge lets two implants carry three or four teeth, so you do not need one implant per tooth.

A loose denture

An implant-retained denture clips onto implants so it stays put when you eat and talk.

A full arch

All-on-4 fixes a full arch of teeth on four implants. A wider full mouth restoration is also possible.

Is an implant suitable for me?

FactorWhat it means for you
Gum healthGum disease can affect healing and suitability, so we treat and stabilise it first.
SmokingSmoking can affect how the gum and bone heal. We talk about it openly and assess you individually.
Diabetes and general healthDiabetes and some other conditions can affect healing. Many people with well-managed conditions can still be considered.
AgeImplants are placed once the jaw has finished growing. After that, general health matters far more than age.
BoneYour CBCT scan shows how much there is before you commit to anything.

Questions about how implants work

Is an implant just a false tooth?

Not quite. The crown on top is made in a laboratory, but the post underneath replaces the root and is held by your own bone. It is fixed, so it does not come out like a denture.

Can my body reject an implant?

An implant is not living tissue, so it is not rejected like a transplanted organ. Occasionally one does not bond with the bone; if so, we explain what can be done.

Will it feel like my own tooth?

It feels firm and solid. An implant has no nerve inside, so biting can feel slightly different at first, but most people quickly stop noticing it. Placement is done under local anaesthetic; we do not offer sedation.

Do implants need special cleaning?

Brush twice a day, clean between your teeth with small interdental brushes, and keep up regular check-ups and hygiene visits. The gum around an implant can become inflamed if plaque is left, just like around a natural tooth.

How long until I have a tooth again?

The final crown usually follows a few months after the implant is placed. For a visible tooth, we plan a temporary so you are not without a tooth at work.
