A darker or grayish gum around a dental implant is usually caused by thin gum tissue letting the titanium abutment show through, gradual recession, or, less commonly, inflammation called peri-implantitis. Mild discoloration without pain or swelling is often esthetic and treatable with a gum graft or zirconia abutment, but new swelling, bleeding, or pus needs prompt evaluation.

At Inspire Dental in Tigard, this is one of the most common cosmetic questions we hear from implant patients. Someone leans into the bathroom mirror, catches a shadow at the gumline, and wonders if their implant is failing. Usually it isn't. But the answer depends on a few things worth understanding.

Is it normal for the gum around an implant to look darker?

A subtle color difference can be perfectly normal, especially if your gum tissue is naturally thin. Implant fixtures are typically made of titanium, and titanium is gray. When the tissue covering it is thin or slightly translucent, some of that color reads through. Think of it like a tattoo seen through a layer of skin.

The honest test: compare the gum around your implant to the gum around the matching tooth on the opposite side, and to your other natural teeth. A faint difference in shade with no other symptoms is usually cosmetic. A sudden change is not.

Call us if you notice:

• Swelling or puffiness at the gumline

• Bleeding when you brush or floss the area

• Pus, a bad taste, or persistent bad breath localized to that spot

• Pain, throbbing, or a feeling that the crown has shifted

Those are different problems. Those need a visit.

What causes the gum around a dental implant to appear gray or darker?

There are five common reasons, and most are not emergencies.

1. Thin gingival biotype. Some people naturally have thinner, more delicate gum tissue. Research published in the Journal of Periodontology associates a thin biotype with greater risk of recession and visible abutment show-through around implants. If your gums are on the thin side, the titanium underneath has less tissue masking it.

2. Gum recession over time. Even healthy gums can recede a millimeter or two over the years. When that happens around an implant, more of the metal collar becomes visible. This is a slow process, often noticed years after placement.

3. Peri-implant mucositis or peri-implantitis. According to the American Academy of Periodontology, peri-implantitis is an inflammatory condition affecting the soft and hard tissues around dental implants and can lead to bone loss if untreated. Inflamed tissue can look darker, redder, or duskier than healthy gum. This one needs treatment.

4. Metal abutments under translucent tissue. Older implants almost always used titanium abutments, which the ADA notes is still the most common material for both implant fixtures and abutments. Newer cases sometimes use zirconia (a tooth-colored ceramic), which can reduce gray show-through in patients with thin tissue.

5. Bruising during the first one to two weeks after surgery. AAOMS patient education materials note that minor color changes and bruising are common in the early healing window and typically resolve on their own. If your implant was placed recently, give it time.

When should I worry about discolored gums near my implant?

Gradual gray show-through without symptoms is almost always an esthetic issue, not a health one. You can live with it indefinitely. Many patients do.

What changes the conversation are the red flags: swelling, pus, bleeding on brushing, a metallic or sour taste at the site, deep aching, or any sense that the crown moves. Peri-implantitis is treatable when caught early. Left alone, it can quietly cost you bone, and bone loss is much harder to reverse than gum inflammation.

A patient from the Summerfield retirement community came in last spring worried that her 12-year-old upper front implant had "gone bad" because the gumline looked darker than she remembered. After exam and X-rays, the implant was healthy. The tissue had simply thinned with age and the titanium was reading through. We talked through her options. She chose a soft tissue graft, and the gray disappeared.

That is the more common story. Not failure. Tissue.

How is gum discoloration around an implant treated?

Treatment depends on the cause. We never chase cosmetics over an active infection, so step one is always ruling out peri-implant disease.

If the implant is healthy and the issue is esthetic:

• Connective tissue graft. A small piece of tissue, often taken from the palate, is tucked under the gum at the implant site to thicken it. Research in the Journal of Clinical Periodontology supports connective tissue grafting as a way to increase soft tissue thickness around implants and improve esthetics. This is the most reliable fix for gray show-through.

• Swap the abutment to zirconia. If the crown is removable and the tissue allows it, replacing a titanium abutment with a ceramic one can eliminate the gray underlayer. Studies in the International Journal of Oral & Maxillofacial Implants suggest zirconia abutments can reduce gray show-through in thin-tissue patients.

• Pink porcelain or composite at the crown margin. In select cases, a thin band of gum-colored ceramic can mask exposed metal or recession without surgery.

If there is active peri-implant disease: We start with professional debridement around the implant, often with specialized instruments and irrigation. More advanced cases may need a surgical cleaning, antibiotic therapy, or, rarely, implant removal. Catching it early is everything.

How can I prevent gum color changes around my implant?

Some prevention happens before the implant is ever placed. Some happens every day after.

Before placement, ask about your tissue thickness and which abutment material is planned. If you have a thin biotype in a visible area like an upper front tooth, a graft at the time of surgery or a zirconia abutment can save you a touch-up later.

After placement, the basics matter more than gadgets:

• Brush twice a day with a soft brush

• Clean between teeth with implant-safe floss or a water flosser

• Keep your peri-implant maintenance visits, usually every three to six months

• Avoid tobacco. The AAP and Cochrane reviews both identify smoking as a recognized risk factor for peri-implantitis and implant failure

Many of our Bull Mountain and King City implant patients drive in from along the Pacific Highway corridor, and a few commute from Tualatin or Sherwood. We schedule maintenance visits early morning or late afternoon so they fit around the Highway 217 rush. Consistent care is what keeps the tissue, and the color, stable for the long haul.

Frequently Asked Questions

Can a dark gum line around an implant be fixed without removing the implant?

Yes, in most cases. The implant itself stays put. Treatment usually involves either thickening the gum tissue with a connective tissue graft or, if accessible, swapping a titanium abutment for a tooth-colored zirconia one. Implant removal is reserved for failing implants, not cosmetic issues.

Does a gray gum mean my implant is failing?

Usually no. Gray show-through by itself is almost always a tissue thickness issue, not a failure. Failure typically comes with pain, swelling, looseness, bleeding, or a bad taste. If the color is the only change, it is most likely esthetic and can be addressed without urgency.

Will a gum graft make the discoloration go away permanently?

For most patients, yes. A successful connective tissue graft adds permanent thickness to the gum, which masks the underlying metal and protects against future recession. Long-term outcomes are good, especially when paired with consistent home care and regular maintenance visits.

Are zirconia implants better than titanium for preventing gum discoloration?

Zirconia abutments (the part visible at the gumline) can reduce gray show-through in patients with thin tissue. Full zirconia implants exist but are not a fit for every case. Titanium remains the most studied and predictable material overall. The right answer depends on your tissue, your bite, and the tooth in question.

How long after implant surgery should bruising in the gums fade?

Most post-surgical bruising and color changes resolve within one to two weeks. If discoloration persists past three weeks, or is paired with pain, swelling, or discharge, give us a call so we can take a look.
