How to get white stains off teeth

White tooth marks may be plaque, enamel demineralisation, fluorosis, or hypomineralisation, and treatment depends on the cause.

A chalky area can reflect mineral loss from acid or plaque, while a developmental enamel defect forms as the tooth develops. A mark that does not brush away is part of the tooth surface rather than a removable stain.

A dentist checks texture, location, symmetry, plaque, diet, fluoride exposure, decay risk, and development history. Treatment can include remineralisation support, resin infiltration, enamel microabrasion, selected whitening, or restoration.

Use fluoride toothpaste, clean along the gum margin, limit frequent acidic or sugary drinks, and avoid abrasive scrubbing. Do not scrape the mark with a sharp object.

Arrange an examination if the mark is new, rough, sensitive, enlarging, or associated with pain. Ask whether it is active mineral loss, a developmental defect, or a surface deposit and which treatment preserves enamel.
