Whiten teeth

“Bi-carb soda has been found to remove many stains from teeth so teeth are whitened by its use,” Sebold says. “But bi-carb soda does not contain cavity-fighting fluoride,” she explains. Sebold suggests using bi-carb soda a few times a week, alongside a fluoride-containing toothpaste for the rest of the week. This will “ensure the most favourable outcome in terms of cavity prevention, whitening and safety”.
