Baking soda help whiten teeth
Baking soda may remove some surface stains, but it cannot bleach the deeper colour within a tooth.
Can baking soda whiten the colour inside a tooth?
Baking soda may remove some surface stains, but it cannot bleach the deeper colour within a tooth.
Why does baking soda mainly affect surface deposits?
Baking soda is sodium bicarbonate and mainly loosens surface deposits; it does not oxidise internal tooth colour.
How can you avoid damage while brushing stains?
Use fluoride toothpaste for routine brushing and avoid vigorous scrubbing with loose powder. Cleaning and peroxide whitening address different types of discoloration.
When should a dark tooth or whitening pain be checked?
See a dentist for a single dark tooth, persistent stains, or whitening pain.
How could fillings look after professional whitening?
Ask whether the colour is surface stain or internal discoloration and how fillings will appear after whitening.
