Can brushing teeth with salt whiten teeth?
Disease description:
My teeth are slightly yellow. I've heard from some friends that brushing teeth with salt can help whiten them, but I'm a bit skeptical. So I'd like to ask: can brushing teeth with salt actually whiten teeth?
Brushing teeth with salt can whiten teeth to a certain extent. This is mainly because salt helps clean the surface of teeth and enamel, thereby producing a whitening effect. However, it cannot penetrate into the dentin layer, so the whitening effect may not be particularly significant. If patients wish to achieve thorough teeth whitening, they can seek professional treatment at a hospital, such as dental cleaning or cold-light whitening procedures.
