Can you brush your teeth with baking soda and peroxide
Baking soda can remove some surface deposits, but peroxide mixtures and abrasive brushing may irritate oral tissues.
The short answer
Baking soda is sodium bicarbonate, an alkaline powder that can help remove surface deposits, but peroxide mixtures and abrasive brushing can irritate oral tissues.

What is the direct answer?
What does this question mean?
Sodium bicarbonate is a mild abrasive and buffer. It can polish some extrinsic stain, but it does not replace fluoride’s role in strengthening enamel against acid attack; hydrogen peroxide adds an oxidising agent that can irritate mucosa and increase sensitivity.
What can you do next?
Use a fluoride toothpaste and a soft brush for routine cleaning. Do not scrub with dry powder or combine household ingredients; if a clinician recommends a product, follow its labelled directions and stop if tissues become sore.
When should you seek dental care?
Ask a dentist to assess sensitivity, enamel wear, cavities, ulcers, or gum irritation before using home mixtures. Get prompt care for chemical irritation, persistent pain, or a whitening result that is patchy around restorations.
What should you ask the dentist?
Ask what diagnosis explains this finding, what examination or imaging is needed, which treatment addresses the cause, and how to protect the result afterward. Ask which symptoms would require an earlier review.
Frequently asked questions
Can baking soda replace toothpaste?
It does not provide the same fluoride protection as a fluoride toothpaste. It may remove some surface deposits, but routine brushing should use toothpaste formulated for oral care.
What should I avoid while waiting for care?
Avoid aggressive scrubbing, sharp objects, unprescribed medication changes, and attempts to drain or repair the area yourself. Keep routine gentle cleaning unless a clinician gives different instructions.
