Baking soda and lemon on teeth
Baking soda and lemon are not a controlled whitening treatment: lemon acid can soften enamel, while scrubbing can abrade the surface.
The short answer
Citric acid can dissolve mineral from enamel during contact. Baking soda may remove some deposits by abrasion, but it does not safely bleach internal tooth colour.
What is the direct answer?
What does this question mean?
Repeated acid exposure can soften enamel, and brushing immediately afterward adds mechanical wear. Root dentin is also vulnerable to abrasion.
What can you do next?
Do not brush with a lemon and baking soda mixture. Rinse after acidic foods, wait before brushing, use fluoride toothpaste, and clean plaque gently.
When should you seek dental care?
Arrange care for sensitivity, rough or translucent enamel, pain, or persistent colour change. Examine a single dark tooth or cavity before whitening.
What should you ask the dentist?
Ask whether colour is surface stain or internal change, whether enamel is affected, and which controlled option fits your mouth.
