Dark purple discoloration beneath the gums may be caused by pigment changes, similar to how moles or spots sometimes appear on the skin. In such cases, there is no impact on health—only a change in color occurs. If there are metallic restorations or metal-ceramic crowns, ionization through saliva can cause the release of metal ions, which may also lead to purple discoloration of the gums.
