The identical might be stated for baking soda, though there’s extra of a scientific foundation to the worth of utilizing sodium bicarbonate to brush your enamel, Messina defined.

The erosion of enamel also can trigger enamel to change into extra yellow over the long-term, because the yellow-colored dentin, the inside layer of tooth, is uncovered.

There’s no means to know the way a lot is an excessive amount of scrubbing with salt, as a result of all people’s case is totally different, Messina defined. “But enamel doesn’t grow back … once it’s gone, it’s gone.”

There is nothing there that would be abrasive.”

If common brushing and flossing is not giving you the outcomes you need, each Grossman and Messina advocate a personalised, in-office session with a dentist. “There are safe and effective whitening techniques, but they will be different for each individual person,” Messina stated.
