What is the direct answer?
Lemon and baking soda do not provide a controlled tooth-whitening treatment and can irritate gums or alter the tooth surface.
What does this question mean?
Lemon contains acid, while baking soda is an abrasive powder; acid can soften enamel temporarily and abrasion can remove surface material rather than change the tooth's internal color.
What can you do next?
Use fluoride toothpaste and ask about professionally supervised whitening after decay, gum disease, restorations, and sensitivity are checked.
When should you seek dental care?
Stop the mixture and seek care for burning, severe sensitivity, gum peeling, or persistent pain.
What should you ask the dentist?
Ask whether the discoloration is surface stain, enamel change, dentine color, or a restoration that whitening cannot change.
