What is the direct answer?
Baking soda can help loosen some surface deposits, but it does not replace fluoride toothpaste or diagnose and treat decay and gum disease.
What does this question mean?
Tooth whitening depends on whether colour lies on the surface or within enamel and dentin. Abrasive particles can affect external stain, whereas peroxide-based products use oxidation; neither approach repairs structural damage.
What can you do next?
Use a toothpaste formulated for oral care and brush with a soft brush rather than scrubbing with dry powder. Do not mix it with acids, peroxide, or abrasive substances, and do not use it to postpone treatment for pain or bleeding.
When should you seek dental care?
Ask for dental advice when teeth are sensitive, worn, chipped, or discoloured from within, or when gums bleed. Pain, swelling, or a visible hole needs examination rather than a whitening remedy.
What should you ask the dentist?
Ask whether the discolouration is surface stain or internal, whether enamel wear or sensitivity is present, and which fluoride toothpaste or professional option fits your mouth.
