An implant cannot decay, but it can be lost. What threatens it is not a cavity but inflammation in the gum and bone around it — peri-implantitis — driven by plaque, and made significantly more likely by smoking, by a history of gum disease and by uncontrolled diabetes. Long-term success is mostly a matter of daily cleaning and regular professional review, neither of which is complicated.
This is worth understanding properly, because the phrase “implants cannot decay” is often heard as “implants need no looking after”, and the second is not true.
Why an implant is more vulnerable than a tooth to gum problems
A natural tooth is attached to the bone by a periodontal ligament, with fibres that run into the root surface and a good blood supply in the tissue around it. An implant is fused directly to bone, and the soft tissue around it attaches in a way that is less well sealed and less well supplied with blood.
The practical consequence is that inflammation around an implant tends to progress faster and with fewer warning symptoms than the equivalent around a tooth. It is easier to treat early than late, and by the time it is obvious there has usually been bone loss.
Daily care around an implant
Brushing
Twice a day with a soft brush, with particular attention to where the crown meets the gum. An electric brush is helpful but not essential. Aggressive scrubbing is not: it damages the gum without cleaning better.
Cleaning between and underneath
This is the part that matters most and the part most often skipped. Use an interdental brush of the right size around the implant, or floss designed for implants. Where the implant carries a bridge, you have to clean under the span with a floss threader, superfloss or an interdental brush — ordinary floss cannot be passed between joined units. A water flosser is a useful addition, particularly around full-arch work, but it does not replace physical cleaning.
If you are unsure whether you are doing this effectively, ask to be shown at your next visit with your own implant in front of you. Most people are cleaning the crown and missing the margin.
What to avoid
Abrasive whitening pastes, which can scratch the crown’s surface and leave it more plaque-retentive. Using teeth as tools. Chewing ice or very hard objects, which risks chipping the crown.
Professional review
Implants need checking at intervals, typically every six months and more often for higher-risk patients. A review is not a formality: it includes probing the tissue around the implant, checking for bleeding, confirming the crown and abutment are not loose, checking the bite, professional cleaning with instruments that will not damage the implant surface, and periodic radiographs to compare bone levels over time.
That last point is the reason reviews matter. Bone loss around an implant is measured, not felt. A baseline radiograph after the crown is fitted gives everything afterwards something to be compared against.
The risk factors that actually change the odds
Smoking. The strongest modifiable risk factor for implant complications, and the one most consistently associated with implant loss.
A history of periodontitis. If gum disease cost you the tooth, the same susceptibility remains and the implant needs closer monitoring. Our gum and periodontal care page covers the ongoing management.
Uncontrolled diabetes. Control is what matters, not the diagnosis itself.
Grinding and clenching. An implant has no ligament to absorb shock, so sustained overload is transmitted straight into the bone and the components. If you grind, wear the night guard you were given — it is protecting the implant, not just your teeth.
Poor plaque control. Everything above interacts with this one.
Warning signs worth acting on
- Bleeding from the gum around the implant when you brush or clean.
- Swelling, redness or tenderness around it.
- A bad taste or persistent odour from that area.
- The gum receding so that the metal edge becomes visible.
- The crown feeling loose, or a change in how it meets the opposing teeth.
- Food packing into a space that was not there before.
Bleeding around an implant is not something to watch for a few months. It is the early stage, and the early stage is the treatable one.
Frequently asked questions
Can peri-implantitis be treated?
Early inflammation confined to the soft tissue usually responds well to cleaning and improved home care. Once bone has been lost, treatment is more involved and the lost bone does not simply return, which is the argument for catching it early.
Do I still need check-ups if all my teeth are implant-supported?
Yes, arguably more than before. There is more implant surface to monitor and no natural teeth to give the earlier, more obvious warning signs.
Can a crown on an implant be replaced?
Yes. A screw-retained crown is straightforward to remove and refit, which is one of its advantages. The implant itself stays in place.
How long will my implant last?
That depends largely on the factors above rather than on the implant. See how long dental implants last.
Book your implant review
If it has been more than a year since your implant was checked, or since a radiograph was taken of it, that is worth putting right. See our dental implants page or book an appointment.
