Baking soda for teeth side effects

Baking soda can remove surface deposits, but repeated or forceful brushing may irritate gums and increase enamel wear.

Baking soda is sodium bicarbonate, a mildly abrasive powder. It can lift some external stains from enamel, but it does not bleach teeth or change the colour of fillings, crowns or veneers.

Use a soft toothbrush and gentle pressure, and do not scrub with dry powder or acidic mixtures. Fluoride toothpaste is the routine option for cleaning and cavity prevention; persistent staining should be assessed before whitening.

Arrange an examination if brushing causes bleeding, burning, gum recession, sensitivity or grooves near the gumline. A persistent dark mark also needs assessment because decay and internal discolouration require different treatment from surface staining.

Ask whether the colour is a surface stain or an internal tooth change, whether enamel or root dentine is exposed, and which cleaning or whitening method suits your restorations. Ask which symptoms mean you should stop a product.
