How long do dental implants last, and what needs maintaining?

Dental implants can remain in use for many years, but no implant has a guaranteed expiry date—or a guarantee of lasting for life. It also matters which part of the treatment you mean: the implant in the bone, the crown above it and the connecting parts do not necessarily need attention at the same time.

When comparing options, ask what can go wrong, what can be repaired and what ongoing care will involve.

What do long-term studies actually measure?

A 2019 systematic review by Howe and colleagues combined 18 prospective studies and estimated 96.4% implant survival at ten years. A sensitivity analysis allowing for missing follow-up data gave a lower estimate of 93.2%.

Those figures describe implants remaining in place across the included studies. They are not the chance that every patient will have ten years without a repair, nor a result measured at Ethical Dental. Individual risks and treatment circumstances vary.

“Survival” is therefore useful, but incomplete. A surviving implant can have needed treatment or a replacement crown along the way.

Does the crown last as long as the implant?

It may not. The crown is the visible tooth used for biting and chewing; an abutment connects it to the implant. Ceramic can chip, a connection can loosen and the shape or bite may need attention over time.

Some problems can be repaired while retaining the implant. Others need a replacement crown or more involved treatment. The design and condition of the components determine what is possible. Ask how your restoration would be accessed for repair, and what information about the implant system you should keep.

There is no single crown-replacement timetable that applies to every patient. Your dentist should assess its condition rather than replace it simply because a set number of years has passed.

Can an implant get gum disease?

Yes. Inflammation limited to the soft tissues around an implant is called peri-implant mucositis. Peri-implantitis also involves progressive loss of supporting bone. These conditions need assessment and treatment; an implant cannot get tooth decay, but its surrounding tissues can become unhealthy.

The EFP's clinical guidance emphasises prevention and ongoing supportive care. Keeping plaque under control, managing gum disease and addressing relevant risks are part of that care. A previous history of gum disease, smoking and poorly controlled diabetes deserve attention in an individual assessment.

Treatment depends on the findings. It is not accurate to promise that a clean alone will stop every case of peri-implantitis or restore lost bone.

What should I have checked?

Contact your dentist about persistent bleeding, swelling, discharge, a new unpleasant taste, recession around the implant or a crown that feels loose or different when you bite. These signs can have different causes; they do not all mean the implant has failed.

A loose connection and an implant that has lost its attachment to bone are different problems. They need a clinical examination to distinguish them. Avoid chewing on a loose restoration and arrange a prompt assessment.

Pain is not a dependable early-warning system. Routine review remains useful even when the implant feels comfortable.

What does ongoing care involve?

Ask for a cleaning demonstration with the tools that fit your restoration. Being told to “floss around it” is less useful than being shown exactly where to clean and having a chance to try it.

At review visits, the dentist assesses the restoration and surrounding tissues. The timing of reviews and any X-rays should reflect your circumstances. Tell the team if your health, medicines, smoking status or ability to manage cleaning has changed.

If grinding or clenching is a concern, discuss the bite and whether a protective appliance would be appropriate. Such an appliance is not a guarantee against implant or crown complications.

Does titanium wear out or rust?

Titanium resists corrosion, but “it can never corrode” is too strong. Our separate article on whether dental implants rust or corrode explains that distinction. For day-to-day care, new symptoms and changes deserve a dental assessment rather than a guess about the metal.

Include maintenance in the decision

Before proceeding, ask what reviews are included in the treatment fee, what long-term maintenance may cost and what would happen if a crown needed repair. Those questions belong beside the initial treatment price.

Our dental implant page explains treatment with Dr Sam Rosehill in Coffs Harbour and the current fees. If you are weighing up replacing a tooth, you can request a tooth-replacement consultation. If you already have an implant with symptoms, contact the team and describe the problem so they can arrange the appropriate assessment.
