Apparently drinking strong black coffee can help keep your teeth clean and strong. There are chemicals in coffee,called polyphenols, that attack the biofilm bacteria that causes tooth decay. Obviously having milk and sugar in your coffee would negate that effect. I understand that this has all been scientifically proven. I would like to add my ‘research’ to those scientific studies. I had to have quite a few fillings in my teeth when I was younger. I haven’t had a filling for many years and before you ask I don’t have false teeth…..yet! I never drank coffee as a child, in fact I probably didn’t start drinking a lot of coffee until I was in my twenties. I get through up to six large black Americanos a day now. So is that why my teeth are so healthy? Maybe it is, but it is probably the reason I am so wired and don’t need much sleep! You can’t win them all can you? Maybe Dentists should replace those minty mouthwashes with a coffee flavoured version though.
