Summer diet: what to eat to keep a healthy smile all summer long?

Published on July 23, 2025

Summer is a time of joy, relaxation, and... many small, delicious pleasures. Aperitifs on the terrace, sweet fruits, refreshing drinks... These moments are good for the soul, but they can also pose a challenge for your oral health.

At The Smilist, we believe it's possible to enjoy summer without compromising your smile. In this article, discover which foods to favor to protect your teeth and which to limit to prevent enamel erosion or cavities. And of course, we're sharing some gentle rituals to complete your oral care routine!

The Best Foods for Healthy Teeth in Summer

1. Fruits rich in water: to hydrate and neutralize acidity

Watermelon, melon, cucumber… These water-rich foods stimulate salivation, a natural mechanism that neutralizes the acids responsible for cavities.
-> Little extra: saliva naturally contains enzymes that repair enamel.

2. Dairy products: to strengthen enamel naturally

Cheese and unsweetened plain yogurts are rich in calcium and phosphates, two minerals essential for enamel mineralization. They are an easy addition to a healthy breakfast or snack.

3. Crunchy raw vegetables: for gentle cleansing

Raw carrots, celery, and peppers have a fibrous texture that acts like a natural mini-brush. Perfect as a snack or appetizer, they dislodge food debris while massaging the gums.

4. Nuts: satiety and minerals without added sugar

Walnuts, almonds, and hazelnuts are rich in magnesium, calcium, and phosphorus. They reduce sugar cravings and don't stick to your teeth. A healthy and enjoyable ally.

5. Sugar-free water and infusions: for a healthy and fresh mouth

Drinking water regularly helps to eliminate food residues and maintain good hydration of the oral mucosa.

Need a natural boost of freshness between appointments or while out and about? Discover our The Smilist Purifying Mouth Spray, alcohol-free, enriched with probiotics for healthy breath and respected oral balance!

Foods and drinks to limit (without necessarily banning them!)

1. Sweet sodas and cocktails: the sugar + acidity combo

Sugary drinks are acidifying and demineralizing. Sugar feeds the bacteria that cause cavities, and the acidity attacks enamel.

-> Tip: rinse your mouth with water after consumption, then stimulate saliva with sugar-free chewing gum!

2. Industrial ice cream: sweet pleasure… but sticky

High in added sugars, they stick to tooth surfaces and prolong acid exposure. Opt for homemade ice creams made with simple ingredients!

3. Dried fruits: a false good idea

Although they are energetic and rich in fiber, raisins, figs, and dates have a sticky texture that promotes plaque formation. Consume in moderation.

-> Tip: And to prevent the formation of dental plaque, we also recommend the Micro-Essence Whitening Anti-Plaque from The Smilist ! 

4. Chips, crackers and aperitif biscuits

These foods turn into a sticky paste when they come into contact with saliva and easily slip between the teeth without you realizing it.

The right reflexes to keep a bright smile all summer long

In addition to a balanced diet, adopt a gentle but rigorous routine:

  • Brush your teeth twice a day, with an ultra-soft The Smilist brush with 10 bristles and a respectful toothpaste.
    -> Our toothpaste fluoride-free, Made in France and created by a dentist, strengthen enamel and respect the balance of the oral microbiota.
  • Use dental floss or brushes every night to clean areas that cannot be brushed.
  • Hydrate regularly, especially after a meal or a sugary drink.

Consult your dentist before or after summer to anticipate possible imbalances or sensitivities.

In short

Summer can be a wonderful time to take care of yourself... and your smile. By choosing the right foods, practicing gentle hygiene, and incorporating healthy products into your daily routine, you can keep your teeth bright and healthy while enjoying every moment!

At The Smilist, we support you with a gentle, expert and natural approach to oral care.

To everyone, have a wonderful summer, and above all, keep smiling, with confidence.
