Does lemon and baking soda whiten your teeth
Lemon and baking soda do not provide controlled tooth whitening and can expose enamel and dentine to acid and abrasion.
The short answer
The mixture does not provide controlled whitening. Lemon juice is acidic, while baking soda is abrasive; repeated contact can soften enamel and wear its surface, exposing more yellow dentine.

What is the direct answer?
What does this question mean?
Whitening changes the colour of natural tooth structure through a peroxide-based process. Lemon and baking soda mainly alter surface deposits temporarily, and they cannot reliably change the colour of fillings, crowns, or veneers.
What can you do next?
Do not scrub the mixture onto teeth or hold lemon juice against them. Use fluoride toothpaste and ask about a dental examination before choosing professional whitening, especially if you have cavities, erosion, gum recession, sensitivity, or restorations.
When should you seek dental care?
Arrange care for sharp sensitivity, pain, translucent or rough enamel, gum irritation, or persistent discolouration. A dentist can distinguish surface stain from intrinsic colour and check the enamel before whitening.
What should you ask the dentist?
Is the colour a surface stain or intrinsic shade, are my enamel and gums suitable for whitening, and will existing restorations remain a different colour?
