With good care, a dental implant can last many years and, for many people, decades. The implant post that sits in the jawbone is designed as a long-term fixture, while the crown on top usually wears faster and may need replacing at some point. How long yours lasts depends on your gum health, oral hygiene, smoking, general health, teeth grinding and regular dental check-ups.
Key takeaways
- A dental implant has three parts: the implant post in the bone, a connector (abutment) and the visible crown. Each part wears differently.
- The implant post is intended to be long-lasting; the crown may need replacing after years of chewing.
- Gum infection around an implant, called peri-implantitis, is one of the main reasons implants run into problems.
- Smoking, poorly controlled diabetes and teeth grinding can all shorten an implant's lifespan.
- Daily cleaning and regular dental reviews are the most practical ways to protect your implant.

How long does each part of a dental implant last?
Each part of an implant has a different expected life. The figures below are general ranges drawn from dental research and everyday clinical experience; your own outcome can be longer or shorter depending on the factors covered later in this article.
Part | What it does | General lifespan pattern |
|---|---|---|
Implant post (fixture) | Titanium screw that fuses with the jawbone and acts as the tooth root | Designed to be long-term; studies commonly report most implants still functioning 10 years or more after placement |
Abutment | Connector that links the post to the crown | Generally long-lasting; screws can occasionally loosen and be tightened or replaced |
Crown | The visible “tooth” you chew with | Subject to wear and chipping; often needs replacing after around 10 to 15 years, sometimes sooner or later |
These are not guarantees. Every mouth is different, and your dentist can give you a clearer picture after examining your teeth, gums and bone. For an overview of how implants are made and placed, see Royce Dental Group’s dental implants page.
Why do some dental implants fail?
Most implant problems come from infection, overload or the bone not bonding well with the implant. Problems can happen early, in the months after placement, or later, after years of use.
Early problems usually happen when the implant does not fuse properly with the jawbone during healing. This fusing process is called osseointegration. Smoking, infection or too much pressure on the implant during healing can interfere with it.
Later problems are more often linked to gum and bone health around the implant. Plaque (the sticky film of bacteria that builds up on teeth) can collect around an implant just as it does around natural teeth. If it is not removed, it can inflame the gums (peri-implant mucositis) and, over time, lead to bone loss around the implant (peri-implantitis). Excessive biting forces from grinding or clenching can also crack crowns or loosen components.
What factors affect how long your implant lasts?
- Oral hygiene. Brushing twice a day and cleaning around the implant with floss, interdental brushes or a water flosser helps prevent plaque build-up.
- Gum health. People with a history of gum disease may have a higher risk of problems around implants and usually benefit from closer monitoring. Our article on gum and periodontal disease explains the warning signs.
- Smoking and vaping. Smoking reduces blood flow to the gums and slows healing, which is linked to higher rates of implant complications.
- Diabetes and general health. Poorly controlled blood sugar can affect healing and raise infection risk. Keeping conditions such as diabetes well managed with your doctor supports your oral health too.
- Teeth grinding (bruxism). Grinding or clenching, often at night, puts heavy force on implants and crowns. A night guard may be recommended.
- Bone quality and volume. Enough healthy bone is needed to support the implant. Your dentist assesses this with X-rays or scans before treatment.
- Implant position and bite. Implants at the back of the mouth take more chewing force. A well-planned bite helps spread that force evenly.
- Regular check-ups. Professional cleaning and reviews allow early signs of trouble to be picked up before they become serious.
How can you make your dental implant last longer?
You can protect your implant with simple daily habits and routine professional care:
- Clean carefully every day. Brush gently around the gumline of the implant crown and clean between teeth daily.
- Keep up with dental visits. Your dentist will advise how often you should come in, commonly every six months, or more often if you have a history of gum disease.
- Stop smoking. If you smoke, quitting is one of the most helpful things you can do for your implant and gums. HealthHub and your polyclinic can support you with quit-smoking programmes.
- Protect against grinding. Wear a night guard if your dentist recommends one.
- Avoid using your teeth as tools. Do not open packets, bite fingernails or crack hard shells with your implant crown.
- Act on early signs. Bleeding, swelling or tenderness around an implant should be checked promptly, not left to see if it settles.
A periodontist, a dentist with additional training in gum health, may be involved in caring for implants in people with gum problems. You can read practical tips in our article 5 things I would and wouldn’t do as a periodontist.
Do dental implants last longer than bridges or dentures?
Implants and bridges are generally considered comparable in how long they last, while dentures may need adjusting or replacing more often. The right choice depends on your mouth, health and preferences, and implants involve surgery and a healing period.
If you are weighing up options for missing teeth, our article on options after losing one or more teeth compares them. For people missing most or all teeth in a jaw, All-on-4 implant-supported teeth are another option to discuss with your dentist.
When to see a dentist
Contact your dentist promptly if you notice:
- Bleeding, swelling, redness or pus around an implant.
- An implant crown that feels loose, moves or makes a clicking sound.
- Pain or discomfort when biting.
- A chipped or cracked implant crown.
- Receding gums that expose metal near the gumline.
- A change in how your teeth fit together.
Many implant problems can be managed more simply when found early. To arrange a review, you can find a Royce Dental Group clinic near you or book an appointment online.
