“A poor diet is often associated with stress, as those with a lot on their mind and working long hours will most likely want to eat quick and easy foods, or skip meals – meaning they won’t be getting the proper vitamins and nutrients they need for optimum health. A poor diet can naturally lead to teeth troubles, especially if you are consuming more caffeine than usual (which will contribute to the yellowing of the teeth), a larger alcohol consumption or sugary drinks, which can promote teeth cavities, as well as plaque build-up.”
