Can bicarbonate of soda whiten teeth safely and effectively?

Bicarbonate of soda is a mildly abrasive alkaline powder that can lift some external deposits, but it does not bleach the internal colour of a tooth.

What can bicarbonate of soda remove from tooth surfaces?

Bicarbonate of soda is a mildly abrasive alkaline powder that can lift some external deposits, but it does not bleach the internal colour of a tooth.

Rubbing loose powder on enamel can vary the abrasive dose and technique, while whitening toothpastes combine abrasives with a controlled formula and fluoride. Neither approach changes the colour of fillings, crowns, or veneers, and deeper stains may need a different diagnosis.

How can you clean teeth without overusing abrasive powder?

Rubbing loose powder on enamel can vary the abrasive dose and technique, while whitening toothpastes combine abrasives with a controlled formula and fluoride. Neither approach changes the colour of fillings, crowns, or veneers, and deeper stains may need a different diagnosis.

Brush twice daily with a soft brush and fluoride toothpaste, using gentle pressure, and choose a tested whitening toothpaste if appropriate for you. Do not mix powder with acids or scrub aggressively, especially over exposed roots or worn enamel.

Which signs of wear or staining need a dental assessment?

See a dentist for a dark single tooth, persistent sensitivity, enamel wear, cavities, or stains that remain after routine cleaning. These signs can indicate a problem that powder cannot correct.
