Can bicarbonate of soda remove stains from teeth?
Bicarbonate of soda may scrub some surface stain, but it cannot bleach enamel or remove tartar, and frequent use can irritate gums or wear enamel.
What is sodium bicarbonate and how abrasive is it?
It is sodium bicarbonate, a mildly abrasive alkaline powder. External pigments sit on the acquired pellicle, while intrinsic colour lies within enamel or dentine.
How should you manage surface stains during daily care?
Use fluoride toothpaste, a soft brush, and gentle pressure. A hygienist can remove calculus with hand instruments or an ultrasonic scaler.
When do persistent marks or sensitivity need assessment?
See a dentist for marks that persist, bleeding, sensitivity, decay, or a single tooth that darkens. Swelling, fever, or severe pain needs urgent care.
Is the mark external, and would cleaning or whitening help?
Ask whether the mark is external or intrinsic, whether enamel or decay is involved, and whether cleaning or whitening is appropriate.
