Can baking soda be used to whiten teeth
Baking soda can remove some surface discoloration, but it does not bleach the tooth and should not replace a dental whitening plan.
The short answer
Baking soda can remove some surface discoloration, but it does not bleach the tooth and should not replace a dental whitening plan. Its fine alkaline particles may polish external stains, while excessive rubbing can wear enamel or irritate gums.
How do enamel stains differ from deeper tooth colour?
Tooth color comes from both outer enamel stains and the deeper dentin beneath enamel. Baking soda acts mainly on the surface, whereas peroxide-based whitening treatments change the color of stain molecules within the tooth structure.
What daily care can help limit further tooth staining?
Brush with a soft brush and fluoride toothpaste, and limit frequent exposure to staining drinks and tobacco. A dentist can check for decay, erosion, gum recession, fillings, or crowns before selecting a peroxide treatment or professional cleaning.
When should teeth be checked before attempting whitening?
Seek care before whitening if teeth are painful, sensitive, cracked, visibly eroded, or marked by a dark spot. A single dark area may be decay or a damaged restoration rather than a removable stain.
What should you ask about the reason for discolouration?
Ask whether the discoloration is extrinsic stain, intrinsic color change, decay, or a restoration. Ask which whitening material is appropriate and how to protect exposed dentin and gum tissue.
