Can you make your teeth whiter with baking soda
Baking soda can remove some surface staining, but it cannot bleach the internal colour of a tooth and excessive abrasion can wear enamel.
The short answer
Baking soda may help lift some external stains because it is a mild abrasive, but it does not change the deeper tooth colour like a peroxide whitening treatment.
What is the direct answer?
What does this question mean?
Surface stains sit on the enamel pellicle and can be loosened during cleaning, while intrinsic colour comes from enamel thickness and dentine beneath it. Abrasive powders do not correct fillings, crowns, decay, or developmental colour changes.
What can you do next?
Use a fluoride toothpaste and a soft brush as the routine approach to stain control. A dentist can identify the stain, treat decay or gum disease, and discuss a fitted peroxide whitening plan when whitening is suitable.
When should you seek dental care?
Arrange an examination for sudden darkening, one tooth changing colour, pain, sensitivity, cavities, or bleeding gums. Whitening should be planned after active disease and defective restorations are assessed.
What should you ask the dentist?
Ask whether the colour is surface or intrinsic and whether any decay or restoration is involved. Ask which whitening method, concentration, duration, and sensitivity precautions fit your teeth.
