Question

note down all the information given on a tooth powder or toothpaste​

Answer 1

two small studies found that tooth powder is superior to toothpaste when it comes to reducing plaque and whitening external stains.

Most tooth powder formulations don't contain fluoride or any type of cavity-fighting ingredient, though.

If cavities are a concern, you may be better off sticking to toothpaste.

Hope it helps :)

ps.. ik that the answer is late.... sorry
