Four foods that protect your teeth from holiday sweets, according to dental expert

As the candy bowls linger from Halloween and holiday treats are unwrapped, your teeth face a marathon of sugar exposure.
"Halloween involves a lot of candy all at once," Olga Ensz, D.M.D., M.P.H., told Fox News Digital.
A clinical associate professor and director of community-based outreach at the University of Florida College of Dentistry, Ensz said the problem isn’t that candy suddenly becomes more dangerous. Instead, "it’s that we eat it in much larger amounts over a short period."
SUGAR IN DRINKS LINKED TO HIGHER DIABETES RISK THAN THAT IN FOOD, NEW RESEARCH FINDS
That rapid-fire sugar intake fuels bacteria that feast on leftover candy, producing acid that weakens enamel and paves the way for cavities.
While brushing and flossing are key, what you eat next can actually help your mouth fight back. Ensz detailed the "Fantastic Four of foods" for dental defense below.

1. Apple as ‘nature’s toothbrush’
"Apples scrub your teeth’s surfaces to disrupt plaque while stimulating saliva flow. Saliva then neutralizes acid and provides minerals to help repair the enamel," Ensz said.

The apple's natural fiber acts as a gentle abrasive, while the boost in saliva helps wash away lingering sugars.
Think of it as a mini mouth cleanse after dessert.

2. Cranberries as the ‘non-stick shield’
Unsweetened cranberries offer more than festive flavor.
"Unsweetened cranberries possess polyphenols with anti-adhesion properties, meaning they interfere with the ability of cavity-causing bacteria to stick to the tooth surface and, ultimately, prevent plaque formation at the source," the professor said.

Just make sure they’re not coated in sugar.
Look for dried cranberries without added sweeteners or use them fresh in salads.

3. Cheese as the 'triple threat'
Cheese, it turns out, provides a triple defense.
After something sweet, a bite of cheese helps neutralize the acid attack. (iStock)
"It stimulates saliva, its alkaline properties help neutralize acid and raise the mouth's pH, and it delivers a direct dose of calcium and phosphates," said Ensz, who added that the latter elements are the "building blocks" for enamel repair.

A small piece of cheese after a meal can counteract acidity from sweets and strengthen the enamel naturally.
4. Pumpkin as the ‘enamel builder’

"Pumpkin is rich in Vitamin A," Ensz said.
Vitamin A is a nutrient essential for the cells that form strong, healthy enamel and make your teeth more resistant to acid.
