How Long Implants Last
An implant is a long-term investment, so it is fair to ask how long it will last. The honest answer is that it depends on a few things you can control and a few you can't. Here is what I tell patients.
How Long Do Dental Implants Last?
A well-planned, well-maintained dental implant can last for decades and often for life, although the crown on top usually needs replacing at some point, commonly after 10 to 15 years or more. At Comely Bank Dental in Edinburgh, a single implant with its crown is £2,900, and how long it lasts depends heavily on your gum health, whether you smoke, how hard you bite and how well it is looked after.
How Long Does a Dental Implant Last?
A dental implant that integrates well with the bone and is looked after can last for decades, and for many people it lasts the rest of their life. It is made of titanium, which doesn't decay, and once it has fused with the bone it becomes a stable foundation.
That said, an implant is not a guaranteed lifetime fix. The implant in the bone and the crown on top have different lifespans, and both depend on your health, habits and maintenance. Research on implants generally shows that a large majority are still in place and working well after ten years, and many continue far beyond that.
I find it more useful to talk about what makes an implant last, because much of that is in your hands and mine.
The Implant and the Crown: Two Different Lifespans
It helps to think of an implant tooth in three parts:
- The implant, the titanium post in the bone. This is the part designed to last indefinitely.
- The abutment, the connector that joins the implant to the crown. It is usually long-lasting but can be replaced if needed.
- The crown, the visible tooth. Like a crown on a natural tooth, it is subject to wear, chipping and the forces of chewing.
The crown usually lasts 10 to 15 years, often longer, before it needs replacing. Replacing an implant crown is normally far simpler than the original treatment because the implant underneath stays where it is. The guide fee for a new implant crown is £1,100.
By comparison, a crown on a natural tooth has a similar lifespan for the crown itself, but the tooth underneath can still decay or crack, which an implant cannot.

What Shortens the Life of an Implant?
A few factors make the biggest difference:
- Smoking. It reduces blood flow to the gums and bone, and smokers have consistently higher rates of implant complications and failure. Stopping helps at any stage.
- Gum disease. If you have had gum disease around your natural teeth, you are more likely to develop a similar infection around an implant, called peri-implantitis.
- Grinding and clenching. Heavy forces can loosen screws, chip crowns and, over time, strain the bone. A night guard can protect the implant.
- Poorly controlled diabetes. Well-managed diabetes is not usually a problem, but poor control affects healing and the gums.
- Infrequent cleaning. Plaque around an implant causes inflammation just as it does around teeth.
- Planning and design. The position of the implant and the shape of the crown affect how easy it is to keep clean and how forces are spread.
None of these automatically rules out implants. They are all things we look at carefully when planning, and some can be improved before treatment starts.
Does It Matter Where in the Mouth the Implant Is?
Position makes some difference, though not as much as gum health and habits.
- Back teeth take the heaviest chewing forces, so crowns there are more likely to chip or wear, and screws are more likely to loosen in people who grind.
- The upper jaw often has softer bone than the lower jaw, which can mean a slightly longer healing period before the crown is fitted.
- Front teeth take less force, but the gum and bone there are thin, so appearance over the long term depends on careful positioning and a healthy, stable gum line.
These differences are taken into account when choosing the implant's length and width, the design of the crown and how often you are reviewed. They are rarely a reason not to have an implant, but they are part of an honest conversation about what to expect.
How Does Careful Planning Help Implants Last?
Implant lifespan starts well before surgery. At Comely Bank Dental in Edinburgh, I plan every implant on a 3D CT scan taken at the practice. The scan shows the bone height, width and angle, so the implant can be chosen and positioned to sit fully in healthy bone, under where the final tooth will be.
I use MegaGen AnyRidge implants, placed with the MegaGen R2 guided surgery system. The plan made on the scan is turned into a 3D-printed guide that directs the drilling to the planned position, angle and depth. A well-positioned implant is easier to clean around and loads the bone more evenly, both of which matter over the long term. IV sedation is available if you are nervous about the surgery.
For context, I have placed over 2,000 implants over more than ten years, with a success rate above 99% (from our practice records). Every mouth is different, and I can't promise any individual result, but careful planning gives each implant the best start.
How Should You Look After an Implant?
Looking after an implant is similar to looking after a natural tooth, with a little extra attention to the area where the crown meets the gum.
At home:
- Brush twice a day, angling the brush towards the gum line around the implant.
- Clean between teeth daily with interdental brushes or floss; your hygienist will show you which size and technique work best for your implant.
- A water flosser can help some people, but it doesn't replace interdental cleaning.
At the practice:
- Regular dental examinations, at which the implant, gum and bite are examined.
- Periodic X-rays to check the bone level around the implant.
- Hygiene visits every three months, which our implant guarantee requires. A hygiene visit is £90. Our hygienist and therapist, Katie Ventisei, uses instruments and Airflow polishing suited to implant surfaces.
If you grind your teeth, wearing a night guard as advised is one of the best ways to protect your implant.
What Warning Signs Should You Watch For?
Many implant problems start quietly, which is why regular checks matter. Contact us if you notice:
- bleeding when you brush around the implant;
- red, swollen or tender gum;
- pus or a bad taste;
- gum receding so that more of the crown or a metal edge shows;
- the implant tooth feeling loose or moving;
- a change in how your teeth meet, or the crown feeling high;
- a chip or crack in the crown.
Most of these are much easier to deal with when found early. A loose crown, for example, is often a simple screw tightening. Our guide on what to do if you think an implant is failing covers this in more detail, and our emergencies page explains how to get seen quickly if you are in pain.
Is an Implant Better Long-Term Than the Alternatives?
For many people, an implant is the longest-lasting way to replace a single missing tooth, but it isn't automatically the best choice for everyone.
- A bridge usually lasts 10 to 15 years, but relies on neighbouring teeth, which are usually prepared for it.
- A partial denture is the simplest option but tends to need replacing or adjusting more often and does not slow bone loss.
- An implant does not rely on neighbouring teeth and helps preserve the bone where the tooth was lost.
On the other hand, an implant involves surgery, takes several months and has a higher initial fee. Some people are better suited to a bridge or denture for medical, financial or personal reasons. At a free consultation, I'll go through the options honestly and help you decide what makes sense for you.
