Dental implants are a popular way to replace missing teeth, and one of the first questions people ask is how long they last. The answer depends on the implant, the crown on top, your general health and how well the area is cared for.
Key points
- The implant post placed in the bone can last many years with good care.
- The crown on top wears with use and may need replacing over time.
- Smoking, gum disease, grinding and poor cleaning are the main risks.
- Regular check-ups and cleans help implants last longer.
The implant post vs the crown
An implant has two main parts. The implant post sits in the jawbone and, once healed, can stay in place for many years. The crown on top is what you see and chew with. Like natural teeth and other crowns, it wears with use and may need replacing at some stage. Individual results vary, and we will talk through what to expect for your situation.
What affects how long an implant lasts
- Smoking, which slows healing and raises the risk of problems.
- Gum health. Infection around an implant, called peri-implantitis, is a leading cause of implant problems.
- General health, such as poorly controlled diabetes.
- Grinding or clenching, which puts extra force on the crown.
- Cleaning and check-ups, which help catch problems early.
How to look after your implant
- Brush twice daily and clean around the implant every day with floss, interdental brushes or a water flosser.
- Keep up regular check-ups and professional cleans.
- Wear a night splint if you grind your teeth.
- Avoid smoking and chewing very hard objects such as ice.
Implants compared with bridges and dentures
Each option has advantages depending on your mouth, bone and budget. Read our comparison of implants, bridges and dentures, or learn more about dental implants at Glenmore Park. Any surgical procedure carries risks; we discuss these with you before treatment.
Signs an implant needs checking
- Bleeding, swelling or tenderness of the gum around the implant.
- A crown that feels loose or a change in how your teeth bite together.
- A bad taste or bad breath around the implant.
- Gum shrinking back so more of the implant or crown shows.
Problems caught early are usually simpler to manage, so contact us if you notice any of these.
Common questions
Do implants need special cleaning?
They need the same daily care as natural teeth, plus careful cleaning where the crown meets the gum. Interdental brushes or a water flosser often help. We can show you the best tools at your next visit.
Can an implant crown be replaced?
Yes. If the crown wears or chips, it can usually be replaced without removing the implant post, as long as the implant and surrounding bone remain healthy.
Is everyone suitable for implants?
Not always. Bone levels, gum health, smoking and some medical conditions affect suitability. An assessment with X-rays or a scan helps decide whether implants, a bridge or dentures suit you best. The Australian Dental Association also has general information about tooth replacement options.
