The short answer
Baking soda is sodium bicarbonate, while baking powder also contains an acid salt and starch, so baking powder is not a substitute for toothpaste or dental treatment.

What is the direct answer?
What does this question mean?
Sodium bicarbonate is an alkaline powder with abrasive action; baking powder is a baking mixture that releases gas with moisture and acid. Neither is a complete fluoride toothpaste.
What can you do next?
Use a soft brush and fluoride toothpaste with light pressure, and clean between teeth daily. Avoid acids and hard scrubbing that can irritate gums or wear exposed tooth surfaces.
When should you seek dental care?
Persistent stains, sensitivity, bleeding, bad breath, or pain needs an examination rather than stronger powders.
What should you ask the dentist?
Ask whether the finding is plaque, calculus, discoloration, erosion, or decay, and which cleaning method fits.
Frequently asked questions
Can home care identify the cause?
Home care may reduce irritation, but an examination is needed when symptoms persist.
