Sometimes, the food you least expect turns out to have surprising cavity fighting benefits. Below are a few that we believe were quite interesting.


Some experts believe that the protein found in cheese known as casein may have protective properties that could help prevent cavities and promote oral health. It has been shown that the calcium levels in the mouth increase after consuming cheese. Our teeth is partly made up of calcium. The calcium present in cheese mixes with saliva to help remineralize teeth and protect the teeth from cavities.

Chewing Gum

Chewing sugar-free gum has been recommended to prevent cavities. The sugar-free variety made with Xylitol – a natural sugar substitute, tends to be more beneficial. Xylitol is an effective cavity fighter that can prevent decay because cavity-causing bacteria cannot use Xylitol to grow and cannot break it down to create acid. It is highly effective in mint form and must be consumed at least three times a day. Be sure to check the ingredients of the gum and see if it is the first listed ingredient to make sure the amount is enough.


We were taught since childhood that the number one enemy of healthy teeth is candy, however, sugar-free candies, similar to sugar-free gums, may hold potential for cavity prevention. Dentists agree that sugar-free candies doesn’t hurt your teeth and if the candy is made with Xylitol, as many hard candies and lollipops now are, then it can actively help fight tooth decay too.


Wine, the red variety, may be thought to leave stains on your teeth but one study showed that many of its components can actively fight bacteria that can lead to cavities and decay. However, dental experts point out that laboratory results do not always relate to actual situations. Dental experts argue that it is important to consider how these chemicals interact with the plaque and biofilm covering every tooth.  


While raisins are deemed as a cause of cavities, it seems that this dried fruit is similar to wine. Scientists have found that certain flavonoids and polyphenols present in raisins can actively fight bacteria that lead to cavities. Yet again, dental experts remain unconvinced of equating this lab result into real life. Raisins have long been avoided as a snack because of their sticky nature and the high sugar content. In addition, it is still to be considered if the cavity-fighting properties of the polyphenols can outweigh the decay-causing properties of sugar.

Use of Straw

When it comes to preventing cavity, acidic, sugary beverages are clearly not a smart choice. However, in one study, it was found out that you can lessen the damage to your teeth by sipping soda with a straw, particularly if you do not allow the straw to come close with the teeth. However, experts still warns of drinking sodas in excess. While a straw can help, the best defense is not drinking these beverages in excess.
