sorry 樓主 off topic

我無否定baking soda升pH同美白用途,輔佐ok,話之你漱口定醃牙,但不認同可以取代用含氟產品,仲要只用soda刷牙

教人唔用正確產品害人蛀牙,到時又話純粹個人經驗呀
你啲point同素人父母group用精油醫金黃葡萄球菌感染一鳩樣,professional/商人永遠係既得利益者逼害你㗎
你咪唔好用囉,照你個logic梳打粉商人愛死你,叫人search但你隻手好似斷撚咗咁 fact check都唔識
西人scienific reseach同dentist說法都幫你search/quote埋喇古人,識唔識google translate呀
現代人有牙膏用牙膏

Dr. Matt Messina, an Ohio-based dentist and assistant professor:
So when commercially available toothpaste didn't exist, he said, baking soda made sense for its ability to polish teeth and reduce acidity. Not everyone uses a toothbrush to clean their teeth -- here's what science says about the alternatives. But that was then; today, you've got better options. In fact, exposing teeth to salt or baking soda could erode the tooth's surface enamel over time. Enamel is like the finished surface of a floor: It's a thin, hard outer layer that protects each tooth. When enamel is worn away by an irritant, such as salt, decay can occur as bacteria in plaque are able to penetrate teeth more quickly, where they produce acids that can lead to cavities.
