Is it ok to use bicarbonate of soda on teeth
Bicarbonate of soda can alter surface deposits, but loose powder lacks fluoride and repeated abrasive cleaning can irritate teeth and gums.
The short answer
Bicarbonate of soda can alter surface deposits, but loose powder lacks fluoride and repeated abrasive cleaning can irritate teeth and gums. A fluoride toothpaste is the better foundation for routine brushing; baking soda does not remove decay or repair enamel.

What is bicarbonate of soda in oral-care products?
Bicarbonate of soda is sodium bicarbonate, a mild alkaline salt used in some formulated toothpastes. Its particles can help lift external stains mechanically, while its chemistry can neutralise acids, but it cannot bleach the internal colour of a tooth.
How should you use toothpaste instead of loose powder?
Use a toothpaste formulated for teeth rather than scrubbing with dry powder, lemon juice, or other mixtures. Brush with a soft brush using light pressure, clean between the teeth, and spit rather than swallowing toothpaste.
When should persistent stains or sensitivity be examined?
Seek an examination for persistent stains, sensitivity, enamel grooves, gum recession, or pain. A dentist can distinguish surface stain from decay, erosion, fluorosis, or changes inside the tooth before choosing whitening or restorative care.
What should you ask about discolouration and fluoride toothpaste?
Ask whether your discolouration is external or internal, whether enamel is worn or exposed, and which fluoride toothpaste suits your needs. Ask how an abrasive product could affect exposed dentine or existing restorations.
Frequently asked questions
Does bicarbonate of soda whiten teeth?
It may lift some surface deposits, but it does not change intrinsic tooth colour like a bleaching treatment.
Can it remove a cavity?
No. A cavity is mineral loss and needs dental diagnosis and treatment.
