Ate too many holiday sweets? 7 foods and drinks that help protect your teeth fast

These coming months will experience an increase in sugary treats, due to three significant U.S. holidays: Halloween, Thanksgiving, and Christmas. Whether it’s leftover Halloween sweets or pumpkin pies for Thanksgiving, several people intake more sugar than usual in this period. This too much sugar consumption can damage teeth, resulting in cavities and decay.

The American Heart Association advises that added sugars should not be more than six percent of everyday calories, almost 25 grams for females and 36 grams for males. As per the U.S. Centers for Disease Control and Prevention, in 2024, 21 percent of adults with the age 20–64 had at least one permanent tooth with decay that's left untreated, and 11 percent of children in the age of two to five had at least one untreated cavity.

Holiday “Sugar Hangover”

Cosmetic dentist Dr. Catrise Austin of New York City cites that by the conclusion of December, mouths can experience what she calls a “sugar hangover.” She describes that sugar interrupts the pH balance of saliva, a major element in oral health, resulting in an acidic environment that damages teeth.


“All that dessert, candy, and sweet drinks leave behind a trail of acids that drop our mouth’s pH from a healthy neutral 7.0 to around 4.5, the level where enamel begins to dissolve,” she cites to The Independent. “That acid attack can last 20 minutes or more after each sugary bite, and when sugar exposure is frequent, your mouth stays in an acidic state nearly all day.”

While brushing and flossing after consuming sweets is important, Dr. Austin cites that specific foods can act as the “mouth’s best medicine”, helping restore pH balance to neutral.

Foods and Drinks That Help Protect Your Teeth

Crunchy Fruits and Vegetables

Fruits and vegetables are rich with vitamins and minerals and are also perfect for dental health. Dr. Austin, host of the podcast Let’s Talk Smiles, advises crunchy items such as apples, carrots, and celery can stimulate saliva.

“Saliva neutralizes acid, restores the pH toward 7.0, and replenishes minerals like calcium and phosphate to repair early enamel damage,” she describes. The American Dental Association adds that saliva offers “disease-fighting substances throughout your mouth to help prevent cavities and other infections.”

Cheese and Yogurt

Dairy is another tooth-friendly choice, mainly after dessert. Dr. Christopher Tolmie, a Florida dentist, cites that cheese delivers calcium and phosphate to repair enamel, and plain yogurt provides similar advantages.

He states that both cheese and yogurt aids to restore the mouth’s pH to a healthy scale of six to seven. Sugary foods, by contrast, can reduce pH to 5.5 or below, leading to situations conducive to cavities.

Leafy Greens

Leafy greens such as kale and spinach also aids oral health. Dr. Austin cites, “They’re high in mineral and folate content that strengthen gums and counteract acid stress.” Their coarse texture lightly scrubs teeth, helping remove plaque and leftover food items.

Unsweetened Green or Black Tea

Sugary drinks such as soda and sweetened juices cause damage to teeth, but tea can be a good suggestion. Dr. Tolmie advises unsweetened green or black tea for its polyphenols, which obstruct bacteria from sticking to teeth.

“These teas have polyphenol, a compound that inhibits bacteria from sticking to the teeth,” he cites. A 2022 research in Molecules confirmed that polyphenols minimize plaque accumulation and reduce the risk of oral infections.

Almonds

Almonds are a simple, tooth-friendly snack that helps in stimulating saliva production. Dr. Steven J. Katz, an Ohio endodontist, cites, “They are packed with calcium and protein, and they help buffer acids. They encourage saliva production, and gently clean the teeth as you chew.”

Sugar-Free Gum with Xylitol

Sticky sweets are to be avoided, but one type of gum variant is an exception. Dr. Katz advises chewing sugar-free gum with xylitol, “a naturally occurring sugar alcohol found in many fruits and vegetables,” which has half the calories of sugar.

“Chewing sugar-free gum stimulates saliva flow, and xylitol specifically helps inhibit the bacteria responsible for cavities,” Katz cites. A 2022 review in the Journal of the International Society of Preventive & Community Dentistry found that consuming 5–10 grams of xylitol daily that includes through gum, significantly minimizes cavity risk.

Water

Finally, the simplest and most cost-effective choice is water. Katz states it as the most effective option.

“Water rinses away food debris and bacterial acids that lead to decay. If it’s fluoridated, it also strengthens and rebuilds enamel,” he describes.
