Summer is all about fresh produce, cookouts, frozen treats, and time with family, and while your taste buds might be thrilled, your teeth may not be.

At Maestri Dental in Lafayette, we’re here to help you enjoy everything the season has to offer without compromising your oral health. The good news? There are plenty of delicious summer foods that actually help strengthen your teeth, and a few you might want to enjoy in moderation.

Here’s our go-to list of smile-friendly summer snacks (and what to skip).

1. Say Yes to Crunchy Fruits & Veggies

Watermelon, apples, carrots, cucumbers, and celery aren’t just hydrating and refreshing; they also help clean your teeth naturally. Crunchy fruits and vegetables stimulate saliva, which washes away food particles and bacteria that can lead to decay.

Smile Tip:
Keep a container of chopped fruits and veggies in the fridge so they’re just as easy to grab as chips or cookies.

According to the American Dental Association (ADA), fiber-rich fruits and vegetables help scrub your teeth and support healthy gums.

2. Cheese, Please!

Cheese is rich in calcium and phosphates, which help strengthen enamel. It also helps balance the pH in your mouth, reducing the risk of cavities.

Smile Tip:
Snack on string cheese or include a slice of cheese on whole-grain crackers for a tooth-friendly afternoon treat.

Dairy products like cheese, milk, and plain yogurt are all part of the ADA’s list of smile-smart foods.

3. Sip Smart

Sports drinks, soda, and sweet tea might be summer staples, but their high sugar and acid content can wear down enamel and fuel cavity-causing bacteria.

Smile Tip:
When you’re sweating it out in the sun, reach for water instead, preferably fluoridated if it’s available. If you do indulge in sugary drinks, use a straw and rinse with water afterward.

According to the CDC, drinking water with fluoride helps prevent cavities by making your teeth more resistant to acid attacks from plaque bacteria.

4. Frozen Treats in Moderation

We all love a popsicle on a hot day, but many frozen treats are packed with added sugar. Eating them frequently, especially between meals, increases your risk of tooth decay.

Smile Tip:
Make your own popsicles using fruit and no added sugar, or opt for a small serving of frozen yogurt with no toppings.

Bonus: Sugar-free frozen treats sweetened with xylitol may even help fight cavity-causing bacteria.

5. Beware of BBQ Sauces & Sticky Snacks

Barbecue sauce, dried fruits, and sticky candies tend to cling to teeth, creating a breeding ground for bacteria. They’re hard to clean off, especially if you’re on the go.

Smile Tip:
Rinse with water after eating anything sticky or sugary, and try to brush as soon as you can. A quick floss can make a big difference, too.

6. Finish Meals with Smile-Friendly Foods

Ending a meal with a piece of cheese, crunchy veggie, or a sugar-free gum can help clean your mouth and reduce the acid left behind from your food.

Smile Tip:
Keep some sugar-free gum (with xylitol) in your beach bag or car. It’s an easy, dentist-approved way to keep your mouth fresh between brushings.
