Can soda bicarbonate whitening teeth
Baking soda may remove surface stain, but it does not bleach inner tooth colour or replace fluoride toothpaste.
The short answer
Baking soda may remove some external stain by mild abrasion, but it does not bleach the deeper colour of teeth and is not a substitute for fluoride toothpaste.
What is sodium bicarbonate used for in toothpaste?
Sodium bicarbonate is a fine alkaline powder used in some formulated toothpastes. Loose powder can be abrasive depending on particle size and brushing pressure, while intrinsic colour from dentine or medication will not be removed by surface polishing.
How should I care for my teeth instead of scrubbing with soda?
Use a formulated fluoride toothpaste and a soft brush rather than scrubbing with household powder. For persistent discolouration, a dentist can identify plaque, calculus, enamel defects, fluorosis, trauma, or restorations before discussing whitening.
When should unexplained tooth staining be examined?
Arrange an examination for a single dark tooth, pain, enamel loss, gum recession, or staining that does not improve with routine cleaning. Stop any method that causes soreness or sensitivity.
Is my tooth colour surface stain or deeper discolouration?
Ask whether the colour is surface stain or intrinsic discolouration, whether professional whitening is suitable, and how an existing restoration will match the result.
Frequently asked questions
Is more baking soda better?
No. More powder or harder brushing can increase abrasion and irritate gums without producing deeper whitening.
Why did the stain return?
New stain can collect from food, drinks, tobacco, plaque, or calculus after surface cleaning.
