At the same time, there is evidence to suggest some polyphenols in apples can lower the ability of cavity-causing bacteria to adhere to teeth. Further, some studies have shown that the antioxidants in apples can help prevent periodontal disease.
Apples even contain a (very) small amount of fluoride. This is worth noting, as fluoride is so important in helping prevent cavities.
Lastly, the act of chewing an apple stimulates saliva production. Saliva helps wash away food debris and bacteria. Remember, though, apples contain sugar and acid so it’s best not to go overboard with them. You can even swish with water after eating one to wash away some of the sugar left behind.
As the science continues to look into how apples affect our teeth, one thing we know is true: regular dental visits, along with daily tooth brushing and flossing, is your best defense against tooth decay
