Observation:

• The photo shows a well-aligned, glossy set of veneers or crowns.

• However, there’s a grayish or bluish tinge near the gum line of one front tooth, with what appears to be a small thread or cotton fiber lodged underneath the gum or crown margin.

Possible Reasons for the Gray/Blue Shade:

1. Underlying Metal Post or Crown Base:
   If your old crown had a metal core (common in porcelain-fused-to-metal crowns), a residual fragment or dark post beneath the gum could now be slightly visible through the thin veneer or gum tissue, especially after removal and replacement.

2. Gingival (Gum) Trauma or Healing Discoloration:
   After crown removal and new veneer placement, gum tissue often undergoes inflammation or minor bleeding. As it heals, it can look bluish or grayish, especially if there’s trapped blood or bruising beneath the surface.

3. Residual Cement or Fiber:
   The blue “cotton” you mentioned may actually be retraction cord — a material used by dentists to gently push the gum aside during veneer placement. Sometimes a small piece can get left behind, causing irritation or slight infection.

4. Early Infection or Tissue Reaction:
   If bacteria get trapped between the veneer margin and gum line (especially after crown removal), it can cause a localized infection or irritation, giving the area a dull gray hue and sometimes mild swelling.

 Why This Happened 

When your old crown was removed in Turkey, the gum around that area experienced stress and slight trauma. The dentist placed new veneers beautifully, but during the cementation, a small piece of retraction cord or cotton thread may have accidentally remained beneath the gum line.

Now, two weeks later, as your tissue heals, that hidden piece is causing inflammation and possibly trapping light, making the area appear grayish-blue.

It’s not necessarily dangerous, but it needs gentle professional cleaning. The gray tone could fade once the tissue calms down and any foreign material is removed.

 Expert Advice

• Do not panic — this is not uncommon in post-veneer healing.

• Wait for your Turkish dentist’s response, but if possible, see a local dentist for a quick gum check and cleaning.

• Ask them to examine for retained cord or cement, and check for early infection.

• Rinse with a chlorhexidine mouthwash (0.12%) twice daily for a week to reduce bacterial irritation.

 When to Seek Immediate Help

• If pain, swelling, or pus develops.

• If the gray area spreads or the gum recedes.

• If you notice persistent bad taste or odor.
