Gum Recession Around a Dental Implant

Patients usually describe this as the implant looking longer, or as a grey line appearing at the gumline that was not there before. Both descriptions point to the same thing: the tissue around the implant has receded.

It is worth understanding early that recession around an implant is not simply a cosmetic version of gum recession around a natural tooth. The mechanism differs, and so do the options.

Why Soft Tissue Recedes Around an Implant

Gum tissue is supported by the bone beneath it. Where bone is lost, the tissue overlying it generally follows. So while recession is what you can see, in most cases it is reporting on something happening a layer below.

That is the central difference from a natural tooth. A tooth has a periodontal ligament and a fibre attachment that provide some resilience. An implant is fused directly to bone with no ligament, and the soft tissue seal around it is less robust. When bone is lost around an implant, the visible consequences arrive sooner.

The Common Causes

• Peri-implant bone loss. The most frequent underlying cause, and the one that matters most because it may be ongoing.
• Thin tissue at the outset. Some patients have a naturally thin tissue biotype. Where the tissue was thin before placement, recession is more likely afterwards.
• Implant position. An implant placed slightly too far toward the cheek or lip side leaves less bone on the outer surface, and that thin plate is vulnerable over time. This is determined at surgery and cannot be adjusted later.
• Insufficient bone volume at placement. Where grafting was needed and not performed, or did not fully take, the supporting envelope may be inadequate from the start.
• Aggressive brushing. A contributing factor rather than a usual primary cause, but hard-bristled brushing with heavy pressure does not help.
• Smoking. Consistently associated with poorer peri-implant tissue outcomes.

The First Question to Answer

Before discussing appearance, the useful clinical question is whether the process producing the recession is still active.

That means an examination for signs of inflammation, probing around the implant, and a radiograph compared against the baseline taken when it was restored. Stable recession that stopped years ago is a different situation from recession accompanying ongoing bone loss, and only the second one is urgent.

Addressing appearance while an active process continues underneath is treating the symptom. Any competent plan resolves the activity first.

What Can Realistically Be Done

If there is active inflammation or bone loss, that is treated first. Stabilising the situation takes precedence over aesthetics, and the extent of what is possible depends on how much support remains.

Soft tissue grafting can be considered in selected cases, and can improve tissue thickness and the appearance of the area. It is important to be realistic: grafting around implants is less predictable than around natural teeth, and it generally cannot restore tissue to cover an implant surface in the way it may around a tooth root. Suitability depends on the underlying bone, the position of the implant, and the tissue available.

Restoration changes are sometimes appropriate. A new crown with a modified emergence profile, or in some cases a pink-shaded ceramic to mask the transition, can improve appearance where surgical options are limited.

Replacement is occasionally the honest recommendation, particularly where the implant is poorly positioned or support is substantially compromised. It is a significant undertaking and is not proposed lightly, but where the underlying position is the problem, treating around it has limits.

Reducing the Risk Going Forward

For an implant already placed, the modifiable factors are maintenance, technique, and smoking. Regular professional review that specifically includes probing and radiographic comparison is the single most useful, because it detects change while options remain broad. A soft brush and moderate pressure, and an interdental technique suited to the restoration, address the mechanical contribution.

If you are still planning an implant, this is an argument for the unglamorous parts of the process: adequate bone, adequate tissue, and correct three-dimensional positioning. Recession is considerably easier to avoid at the planning stage than to correct afterwards.
