Tea
A cup of tea – hold the sugar – can also be a good pick for your teeth. A small Japanese study noted that men who drank green tea daily had lower incidences of gum disease due to its antioxidant content. This positive effect is specifically due to catechin, one type of antioxidant that treats bacteria-related inflammation. Along with being a good source of antioxidants, tea also tends to be high in polyphenols and fluoride, both of which the University of Rochester notes for their ability to keep your teeth's enamel strong and protected against erosion and decay.
You do want to focus on consuming non-acidic drinks, but there may still be a time when you feel like having a glass of wine, soda or some coffee. And that's OK – even if acid erosion is high on your list of concerns, you don't necessarily need to cut those beverages out of your life completely. Instead, enjoy them in moderation, preferably alongside a meal. Remember, you can use a straw to drink them, limiting the contact the acid has with your teeth. Rinsing your mouth with water or even milk at the end of the meal can also keep the surface of your teeth nice and strong.
Keep in mind that even the lowest-acid diet isn't a substitute for brushing twice a day and flossing daily. If you're concerned about losing enamel, you can also start brushing with a fluoride toothpaste like Colgate® Enamel Health™ Multi-Protection Toothpaste which helps to replenish the natural calcium and strengthen your smile. Your dentist might recommend additional treatments, such as a fluoride varnish, to further strengthen your teeth and protect your enamel.
