Does baking soda on teeth work
Baking soda can polish some surface stain, but it cannot bleach deeper tooth color or replace fluoride toothpaste.
The short answer
Baking soda can help remove some surface discoloration because its fine particles are mildly abrasive, but it cannot bleach the inner color of a tooth or replace fluoride toothpaste. Sodium bicarbonate loosens and polishes some plaque and external stains. It does not change intrinsic dentin color, repair enamel loss, treat cavities, or whiten crowns, fillings, and veneers.
How can sodium bicarbonate polish external stains?
Sodium bicarbonate loosens and polishes some plaque and external stains. It does not change intrinsic dentin color, repair enamel loss, treat cavities, or whiten crowns, fillings, and veneers.
How should fluoride toothpaste be used for cleaning?
Use a fluoride toothpaste as the main cleanser and avoid aggressive dry-powder scrubbing. If you want whitening, have the cause of discoloration and the condition of enamel and gums assessed before choosing a peroxide product or professional treatment.
When should persistent stains or pain be assessed?
Seek care for stains that persist after cleaning, one dark tooth, pain, sensitivity, holes, or bleeding gums. These signs can indicate decay, an injured pulp, enamel wear, or gum disease rather than removable surface stain.
Is your tooth discolouration external or internal?
Ask whether your discoloration is external or internal. Ask which fluoride and whitening options fit your enamel, restorations, gum health, and sensitivity.
