How clean teeth with baking soda

Baking soda can help scrub away some surface stains, but it does not replace fluoride toothpaste or remove tartar, cavities, or gum disease.

Baking soda is sodium bicarbonate, a mild alkaline powder used as an abrasive in some dentifrices. Its particles can disturb deposits on the outer enamel surface, while fluoride toothpaste supports enamel remineralization and plaque control through regular brushing.

Use a formulated toothpaste containing fluoride and a soft brush as your routine. Avoid vigorous dry scrubbing, lemon, vinegar, peroxide mixtures, and rubbing powder onto exposed roots, crowns, veneers, or irritated gums.

Ask for an examination if stains do not brush away, teeth are sensitive, gums bleed, or you suspect tartar or decay. A clinician can distinguish external stain from intrinsic discoloration and choose polishing, whitening, restoration, or disease treatment.

Are the marks surface stain, calculus, decay, or intrinsic discoloration? Does my toothpaste contain fluoride? Could abrasion affect exposed dentine or dental restorations?
