How Long Do Dental Implants Last?

This distinction matters when you are comparing quotes or worrying about the future. Replacing a crown on an existing, healthy implant is a straightforward piece of work. Losing the implant itself is a different matter.

• The implant fixture — integrated into bone, and expected to be long term.
• The abutment — the connector, occasionally replaced if a screw loosens.
• The crown, bridge or denture — subject to chewing wear, and the part most likely to need attention first.

The gum and bone around it

The tissue around an implant can become inflamed in the same way gum tissue around a natural tooth can. If that inflammation reaches the bone, the bone supporting the implant is lost, and that is the most common route to losing an implant years after it was placed. It is often painless in its early stages, which is what makes regular checks valuable.

How well it is cleaned

An implant crown does not decay, but the tissue around it responds to plaque exactly as gum tissue does. Daily cleaning between the teeth — with a tool that actually fits that space — is the single most useful habit.

Smoking

Smoking increases the risk of implant problems both during healing and years later. If there is one modifiable factor with an outsized effect, this is it.

General health

Conditions that affect healing and immune response, particularly poorly controlled diabetes, make problems around implants more likely and harder to manage. Some medicines are also relevant, which is why medical history is reviewed before treatment.

Biting force and grinding

An implant has no natural cushioning ligament like a tooth root does, so it feels less and transmits force more directly. Heavy grinding puts stress on the crown, the screw and the bone. If you grind, protection is worth discussing.

Where in the mouth it is

Back teeth take far more load than front teeth, so implant crowns at the back tend to show wear or need adjustment sooner.

A more useful conversation is about risk. Ask which factors in your case are favourable, which are not, and what can be done about the ones that are modifiable. That gives you something to act on.

• Bleeding when you clean around the implant.
• Gum that looks red or puffy on one side.
• A persistent bad taste or odour from the area.
• The crown feeling higher, lower or different when you bite.
• Any movement, however slight.
• Discomfort that was not there before.

1. 1Brush twice daily and clean between the teeth once daily with the right tool for that space.
2. 2Attend every review, including the ones where nothing feels wrong.
3. 3Stop or reduce smoking.
4. 4Keep diabetes and other relevant conditions well controlled.
5. 5Get grinding assessed and protected if it applies to you.
6. 6Report anything that changes rather than waiting for the next appointment.
