It’s officially hot out, and you’re probably already thinking about summer activities, sunscreen, and staying cool. But here’s something that might not be on your radar: the summer heat can actually affect your teeth and gums in ways you wouldn’t expect.

Heat and Hydration Go Hand in Hand With Your Mouth

When temperatures rise, your body works harder to stay cool, and that often means more sweating and a higher risk of dehydration. And when you are dehydrated, your mouth feels the effects too.

Saliva is one of your mouth’s best natural defenses. It washes away food particles, neutralizes acids, and keeps harmful bacteria in check. When you are not drinking enough water, saliva production slows down, leaving your mouth dry and giving bacteria more of an opportunity to thrive.

Signs Your Mouth Might Be Dehydrated

A dry mouth is not always obvious right away. Here are a few signs to watch for during the hotter months.

• A sticky or dry feeling in your mouth
• Bad breath that does not go away with brushing
• Cracked lips or a dry, rough tongue
• Difficulty swallowing or speaking comfortably

If any of these sound familiar, it might be time to increase your water intake, especially if you are spending a lot of time outside this summer.

Some Summer Drinks Can Work Against You

Drinking more in summer is easy, right? Unfortunately, many of the most popular summer beverages are not doing your teeth any favors.

Sports drinks, sodas, lemonade, and sweet iced tea are often loaded with sugar and acid, both of which contribute to tooth decay and enamel erosion. Even seemingly healthy options like fruit juice can be surprisingly high in sugar and acidity.

This does not mean you have to give up cold drinks altogether. Reaching for water as your go-to choice, and saving sugary or acidic drinks for an occasional treat, can make a big difference for your smile over the summer months.

More Free Time Means More Snacking

Summer schedules tend to be looser, with more snacking throughout the day, whether it is at a barbecue, a pool day, summer vacation, or just lounging around the house. Frequent snacking, especially on sugary or starchy foods, gives the bacteria in your mouth a steady supply of fuel.

Unlike mealtime, where your mouth gets a break to recover afterward, grazing throughout the day keeps your mouth in an almost constant acidic state. This is one of the lesser-known ways that a relaxed summer routine can quietly increase your risk of cavities.

Heat Can Also Affect Existing Dental Work

If you have fillings, crowns, or other dental restorations, extreme temperature changes can sometimes cause minor sensitivity or discomfort. Going from an air-conditioned space to intense outdoor heat or enjoying a cold drink right after being in the sun, can cause your teeth to expand and contract ever so slightly. For most people, this is not a major concern, but if you notice ongoing sensitivity, it is worth mentioning at your next appointment.

Staying Ahead of the Heat This Summer

The good news is that protecting your smile from the effects of summer heat does not require a complete overhaul of your routine. A few small adjustments can go a long way.

• Drink plenty of water throughout the day, especially if you are spending time outdoors
• Limit sugary and acidic drinks, even the cold, refreshing ones
• Keep up with regular meals rather than constant snacking
• Stick to your normal brushing and flossing routine, even when your schedule feels more relaxed
