Can baking soda be used for teeth whitening
Teeth may look cleaner after baking soda removes surface deposits, but it does not bleach the internal tooth colour and can abrade enamel.
The short answer
Baking soda can remove some surface staining, but it does not bleach teeth like peroxide whitening and repeated abrasive use can wear enamel or irritate gums.
What is baking soda and how abrasive is it?
Baking soda is sodium bicarbonate, a mildly abrasive alkaline powder. It can scrub some external pigment from plaque, coffee, or tea, while intrinsic colour inside enamel and dentine requires a different whitening mechanism.
How can you clean teeth safely without loose baking soda?
Use a fluoride toothpaste and a soft brush for routine cleaning. For a lighter shade, a dentist can check for decay, gum disease, restorations, and the cause of staining before discussing peroxide trays or in-office whitening.
What could be causing the colour change on your teeth?
Ask whether the colour is extrinsic stain, enamel change, decay, fluorosis, or a discoloured restoration. Ask which whitening material, concentration, contact time, and sensitivity plan fit your teeth.
Frequently asked questions
Can this problem be treated at home?
Home care can reduce irritation, but it cannot diagnose or remove a dental cause such as decay, pulp disease, or an ill-fitting appliance.
What will the dentist check?
The dentist examines the tissues, tests relevant teeth or appliances, and chooses imaging or treatment according to the findings.
