During the war some products were hard to come by, toothpaste was one of these. When toothpaste was in short supply people would use salt to clean their teeth so today I tried this for myself.
Before:OK so I apologise its a bit gross to post a pic of dirty teeth! Plus they're a little wonky!
After: My teeth felt cleaner than they do with regular toothpaste and sparkly and my mouth felt great. Salt has antiseptic qualities so it gives your mouth a really good clean and helps prevent plaque. If you mix one part salt to two parts baking soda it gives an excellent all round clean. If you wish to try this out for yourself be sure to use table salt not rock salt as rock salt is quite abrasive and may damage tooth enamel.
