Black discoloration on the gingival margins of teeth most often occurs due to deposit on the surfaces (plaque, chromogenous bacteria, coffee/tea, tobacco, or ferrous water) instead of
vitamin/mineral deficiency. If the discoloration recurs promptly after scaling, then quick deposit or discoloration-forming behavior is probably occurring.
Next Steps
(1) Maintain good oral hygiene: brush twice daily with fluoridated toothpaste, use dental floss, and consider a mouthwash.
(2) Limit tea, coffee, tobacco, and other staining foods.
(3) Regular dental cleaning may be needed every 3–6 months if stains keep recurring.
(4) Visit a dentist for evaluation of oral hygiene habits and to rule out enamel/dentin issues.
