Can baking soda whiten yellow teeth safely?
Baking soda can remove some surface stain, but it does not reliably change deeper tooth colour and abrasive use can wear enamel or irritate gums.
What is baking soda and how is it used in toothpaste?
Baking soda is sodium bicarbonate, a mildly alkaline powder used in some formulated toothpastes. Its cleaning effect comes mainly from physical stain removal, while intrinsic yellow colour may come from dentine showing through enamel, enamel thinning, ageing, or medication-related changes.
What should you use instead of loose baking soda powder?
Use a fluoride toothpaste made for teeth rather than scrubbing with loose powder. Reduce staining exposures such as tobacco and frequent dark drinks, and have a dentist check cavities, erosion, gum recession, or restorations before whitening.
When should a sudden tooth colour change be checked?
Seek dental care for sudden colour change, one dark tooth, pain, sensitivity, pits, or gum recession. A professional assessment is also useful when home methods produce patchy colour.
Is whitening suitable for your teeth and restorations?
Ask whether the colour is surface stain or intrinsic discolouration, whether whitening is suitable, and how existing restorations will look afterward.
Frequently asked questions
Can baking soda damage enamel?
Repeated forceful scrubbing with a loose abrasive can contribute to surface wear or gum irritation. Use a formulated toothpaste and gentle brushing.
Why do my teeth look yellow after brushing?
Natural dentine is yellowish and may show through translucent enamel; surface stain is only one possible cause.
