Can baking soda damage your gums
Baking soda can irritate gum tissue when used as a concentrated or abrasive scrub, and it does not treat the cause of a gum infection.
The short answer
Baking soda may irritate gums when rubbed forcefully or mixed into a concentrated paste, and it cannot replace diagnosis and treatment of gum infection.

What is the direct answer?
What does this question mean?
Sodium bicarbonate is a fine alkaline powder, but repeated scrubbing can abrade the superficial epithelium and expose already tender tissue to more mechanical irritation. A gum infection may involve plaque, calculus, a periodontal pocket, or an abscess.
What can you do next?
Use a fluoride toothpaste and a soft brush for routine cleaning rather than rubbing loose powder into the gums. If you have already used baking soda and the tissue is sore, stop the mixture and rinse gently with water.
When should you seek dental care?
See a dentist for pus, a gum boil, persistent swelling, bad taste, fever, bleeding, or a loose tooth. Facial swelling or trouble swallowing or breathing is urgent.
What should you ask the dentist?
Ask whether the problem is gingivitis, periodontitis, or an abscess, whether calculus must be removed, and whether a tooth needs drainage or root-canal treatment.
Frequently asked questions
Can baking soda cure a gum abscess?
No. An abscess needs examination to locate its source and may require drainage and treatment of the affected tooth or gum.
What if my gums sting after using it?
Stop the mixture, rinse gently, and seek advice if the soreness persists or the tissue is visibly damaged.
