What to Do If Your Dental Implant Screw Becomes Visible

A patient notices a grey line at the gum margin of an implant, or a distinct edge of metal that was not there before. The immediate assumption is usually that the implant is coming loose. It almost never is.

What has become visible is not, in most cases, the implant itself but the abutment — the connector between implant and crown — appearing because the gum around it has receded or the bone beneath it has reduced.

The important point is that those two explanations have very different implications, and distinguishing them is the purpose of the assessment.

Arrange an assessment. This is not an emergency unless accompanied by pain, swelling, pus or a sense of movement, but it should not be left indefinitely either. Exposure is a sign of change at the site, and identifying the cause early expands the options.

Do not attempt to tighten or adjust anything. Implant screws are torqued to a specified value with a calibrated device. Interfering with the components can damage the connection.

Keep cleaning the area. A rough or threaded surface exposed to the mouth accumulates plaque readily, and stopping cleaning because it looks fragile makes matters worse. Clean gently and thoroughly.

Note what you can observe. When you first noticed it, whether it has changed since, whether there is bleeding, sensitivity or a taste, and whether the crown feels any different when you bite. This information genuinely helps.

Treat pain, swelling, discharge or looseness as urgent. Those findings change the picture and warrant a prompt appointment.

An implant restoration usually has three parts.

The implant fixture is the titanium screw within the bone. Its surface is deliberately textured to encourage bone attachment, which also means it retains plaque readily if exposed.

The abutment connects fixture to crown and passes through the gum. It is machined smooth and is usually what patients see when metal appears.

The crown is the visible tooth, either screwed through the abutment or cemented onto it.

The distinction matters clinically. An exposed abutment is a soft-tissue problem. Exposed fixture threads mean bone has been lost from around them, which is a different and more significant finding.

Our article on implant crown design and maintenance explains how these components relate.

The tissue has migrated apically while the bone level has held. Common contributors include thin gum tissue at the site — tissue biotype largely determines how much recession follows any given event — vigorous brushing with a hard brush, a shallow band of attached gum, or an implant placed slightly too far towards the cheek or lip.

This category is generally the more favourable, because the supporting structure is intact.

Inflammation around the implant has destroyed supporting bone, and the soft tissue has followed it down. Here the exposure is a symptom of active or previous disease.

Suggestive findings include bleeding or pus on probing, deeper pockets than at baseline, and progressive change between reviews. Our article on identifying peri-implantitis early sets out the diagnostic thresholds.

An implant placed too shallow, too far buccally or at an unhelpful angle may show components from the outset, without anything having changed since. Our article on how implant positioning errors affect outcomes years later covers this.

Occasionally a loose abutment screw allows slight movement that irritates the tissue and produces a visible gap. This usually comes with a sensation of movement or a subtle click. Our article on whether bruxism can loosen implant screws explains the mechanism.

A small amount of bone and tissue change in the first year after placement is expected, and in thin tissue it can bring a margin into view without indicating disease.

The assessment is trying to answer one question: is bone being lost, and if so, is it still happening?

Visual examination records exactly what is exposed — smooth abutment or textured fixture — and the appearance of the surrounding tissue.

Probing measures depths around the implant and records bleeding or suppuration. The measurements are compared against baseline records where these exist, because absolute numbers mean little around implants.

Radiographs show the bone level against fixed landmarks on the implant. Comparison with earlier films establishes whether this is stable or progressive — the single most useful piece of information available.

Occlusal assessment checks how the crown is loaded, since heavy or off-axis force accelerates bone loss once inflammation is present.

Component checks confirm the crown and abutment screw are secure.

Risk review covers smoking, diabetic control, gum disease history and cleaning access.

Treatment depends entirely on the answer to that question.

Where the site is healthy and the exposure is cosmetic or mildly sensitive, monitoring with good hygiene is often entirely reasonable. A softer brush, a modified technique and appropriately sized interdental brushes address most of it.

Where appearance matters — a front tooth, or a high smile line — options include replacing a titanium abutment with a zirconia or gold-coloured one to remove the grey cast, or remaking the crown with a longer, contoured form that closes the visible gap.

Soft tissue grafting to thicken or reposition tissue over the exposed component is possible in selected cases, though it is less predictable around implants than around natural teeth, because the tissue cannot attach to titanium in the way it attaches to root surfaces.

Here the exposure is secondary and the disease is the target. Treatment ranges from non-surgical debridement and correction of the underlying cause, through surgical access for direct decontamination, to reshaping or grafting the site depending on the defect. Our article on gums that hurt around an implant covers the symptomatic side.

A loose screw is removed, inspected and replaced or re-torqued to specification. Where the crown contour is causing the irritation, remaking it addresses the cause.

If bone loss is extensive or the implant is mobile, removal may be the sensible course, with a decision afterwards about whether to replace it. Our articles on replacing a failed implant and replacing an old implant set out that pathway.

Left unassessed, exposure tends to produce further problems.

The exposed fixture surface is textured and retains plaque far more readily than a polished one, which accelerates whatever inflammation is present. Sensitivity may develop where the abutment meets tissue. Food packs into the space created. The appearance generally worsens rather than stabilising. And, most importantly, if bone loss is the cause, the process is ongoing and the window in which it is straightforward to arrest is closing.

None of this is inevitable. It is simply why assessment is worth arranging rather than deferring.

Use a soft brush and light pressure. Aggressive brushing is a contributing cause in many recession cases, and harder brushing does not clean better.

Clean interdentally every day with a brush sized to the space. Where access is awkward, a water flosser helps — our article on water flossers for implants covers the options.

Avoid abrasive whitening pastes on exposed metal surfaces; a regular fluoride toothpaste is preferable.

Attend maintenance visits at the interval advised, which will usually be shorter than standard while the site is being monitored.

Report any change — increased bleeding, new sensitivity, a taste, a feeling of movement — rather than waiting for the next scheduled visit.

Our article on cleaning an implant compared with a natural tooth covers technique in more detail.

• What usually becomes visible is the abutment, not the implant fixture itself

• The two underlying causes — soft-tissue recession and peri-implant bone loss — have very different implications

• Exposed textured fixture threads indicate bone loss and are a more significant finding than a visible smooth abutment

• Assessment relies on probing against baseline and radiographic comparison over time

• Pain, swelling, pus or any sense of movement warrant a prompt appointment

• Stable exposure with healthy tissue can reasonably be monitored rather than treated

Is a visible implant screw an emergency?

Not usually. It warrants assessment but not same-day attention, unless it comes with pain, swelling, discharge or a sense of movement — any of which should prompt an urgent appointment. Left entirely unassessed, though, the underlying cause may continue progressing.

Does a visible abutment mean my implant is failing?

Not necessarily. Many cases reflect gum recession over bone that remains stable, which is a soft-tissue issue rather than a failing implant. Probing and radiographs are what distinguish that from bone loss, and the distinction cannot be made by appearance alone.

Can the gum be made to grow back over the metal?

Sometimes, though it is less predictable than around natural teeth, because gum tissue cannot attach to titanium the way it attaches to a root surface. Grafting is an option in selected cases. Often the more reliable route is changing the abutment or crown to address the appearance.

Will it get worse if I leave it?

It may. The exposed surface accumulates plaque more readily, which tends to accelerate inflammation. Where bone loss is the cause, that process continues unless the driver is corrected. Some cases do remain stable for years, but which category you are in requires assessment to establish.

Can the crown be replaced to cover the exposed part?

Frequently, yes. A crown can be remade with a longer, differently contoured form that covers the gap, particularly where the surrounding tissue is healthy. Careful design matters here, since over-contouring to hide metal can create a new cleaning problem.

Why has this happened when I clean carefully?

Thin gum tissue, implant position, brushing pressure and bone remodelling are all contributors that have nothing to do with how diligently you clean. In some cases, over-vigorous brushing is itself a factor. It is worth having the cause identified rather than assuming it reflects your care.

If metal has become visible around an implant, arrange an assessment that includes probing measurements and a radiograph compared against earlier films. That comparison is what determines whether this needs treatment or monitoring.
