How fast can baking soda whiten teeth
Baking soda may polish away some surface stain during brushing, but it does not rapidly bleach the deeper color of teeth and cannot whiten restorations.
The short answer
Baking soda may polish away some surface stain during brushing, but it does not rapidly bleach the deeper color of teeth and cannot whiten restorations. Its action is mechanical: sodium bicarbonate can disrupt plaque and lightly polish external pigment. Tooth color within enamel and dentin requires a different approach, and the visible result depends on the stain, enamel, restorations, and the product used.

How can you brush safely while managing surface stains?
Keep daily brushing gentle with fluoride toothpaste and do not increase pressure or frequency to chase a faster result. A dentist can identify the stain and discuss cleaning, peroxide whitening, or restoration when appropriate.
When could a discoloured tooth need dental care?
Seek care for a single gray or brown tooth, pain, trauma, cavities, gum recession, or sensitivity. Stop abrasive home experiments if the gums become sore or the teeth react persistently to temperature.
What should you ask about the cause and expected result?
Ask what type of discoloration you have and what result is realistic. Ask how to protect enamel and gums, and how existing crowns, fillings, or veneers will look after treatment.
