Is chewing gum good for your teeth? Yes! If you have something sweet for dessert, the bacteria in your mouth consume the sugar and then produce acid as a waste product of this consumption, and this acid demineralises the enamel of teeth and causes decay.


However, chewing gum helps produce saliva. Saliva is a natural buffer to neutralise acids produced by bacteria that feed on sugar. When saliva is produced, some of the acid is neutralised, and this helps reduce the risk of decay. 


However, there is one caveat, which is that the chewing gum needs to be sugar-free, of course, to have any benefit. There are even studies showing that one of the common sugar-free sweeteners in gum, xylitol, has the added benefit of strengthening weakened enamel!
