How to remove the black stain on teeth
A black tooth stain may need polishing, scaling, bleaching, or treatment for decay, depending on whether it is external or within the tooth.
The short answer
A black tooth stain may need polishing, scaling, bleaching, or treatment for decay, depending on whether it is external or within the tooth. A dentist identifies its cause before choosing a removal method.
What can a black mark on a tooth actually represent?
External stain can collect in plaque or calculus and attach to enamel, often near the gumline or in grooves. A dark area can also be caries, a fractured tooth, an old filling, or discoloration from inside the dentin.
What should you do about a black tooth stain now?
Brush twice daily with fluoride toothpaste and clean between the teeth without scraping the spot with metal or abrasive powders. Professional scaling and polishing can remove deposits, while a cavity requires removal of damaged tissue and a restoration.
When does a dark tooth mark need prompt dental care?
Arrange an examination for a new, enlarging, rough, painful, or sensitive dark mark. Urgent care is appropriate when discoloration is accompanied by swelling, fever, drainage, or a broken tooth.
What should you ask about the cause of a black mark?
Ask whether the mark is stain, calculus, decay, or a restoration, and whether an X-ray is needed. Ask which cleaning or restorative step will remove it without removing healthy enamel.
Frequently asked questions
Can brushing remove a black spot?
Brushing can prevent new plaque but usually cannot remove hardened calculus or repair decay.
Is a black line near the gum serious?
It may be stain or calculus, but an examination is needed to exclude decay or a gum problem.
