When cold and flu season hits, most of us focus on getting plenty of rest, staying hydrated, and managing our symptoms. But have you thought about how being sick affects your oral health? Illness can take a surprising toll on your teeth and gums, making it important to maintain proper dental care during cold and flu season.

How Illness Affects Your Teeth and Gums

Being sick creates several challenges for maintaining good oral health when sick. Many common symptoms and remedies can inadvertently harm your smile:

Dehydration and Dry Mouth

When you’re fighting off a cold or flu, dehydration often follows. Fever, reduced fluid intake, and mouth breathing (especially when your nose is congested) can all lead to dry mouth. This condition reduces saliva production, which is problematic because saliva naturally protects your teeth from bacteria and helps neutralize acids. Without adequate saliva, you’re more vulnerable to cavities and bad breath when sick.

Vomiting and Acid Erosion

If you’re dealing with the stomach flu, vomiting exposes your teeth to harsh stomach acids that can cause enamel damage. Many people wonder, “Should I brush my teeth after throwing up?” The answer might surprise you: wait at least 30 minutes. Immediately brushing can actually spread the acid around and damage your already-softened enamel. Instead, wait to brush after vomiting and use a saltwater rinse or a baking soda rinse right away to help neutralize the acid.

Sugary Medications

Cough drops, cough syrups, and other liquid medicines often contain sugar that coats your teeth. While these remedies help you feel better, they can contribute to tooth decay if you’re not careful. Opt for sugar-free lozenges when possible, and rinse your mouth with water after taking any medication.

How to Take Care of Your Teeth When You Have the Flu

Protecting teeth when sick doesn’t have to be complicated. Here are practical steps to maintain your oral health:

Stay hydrated: Drink plenty of water throughout the day to combat dry mouth and support saliva production
Use a saltwater rinse: Mix half a teaspoon of salt in warm water and swish gently to soothe your mouth and neutralize acids
Practice gentle brushing: Your gums may be more sensitive when you’re ill, so be extra careful with your brushing technique
Choose sugar-free options: Select sugar-free lozenges and medications whenever available
Replace your toothbrush: Once you’re feeling better, toss your old toothbrush to avoid reinfecting yourself with lingering germs

Special Considerations During Illness

Sinus pressure can make your upper teeth feel uncomfortable or painful. This is normal and should resolve as your sinuses clear. However, if you experience severe dental pain that persists after your illness, contact our team at Barrington Grove Dental for an evaluation.

If you’re experiencing a dental emergency while sick—such as a broken tooth, severe toothache, or dental abscess—don’t wait to seek care. Visit our emergency dental service page or call us at (847) 382-0818.

Maintaining Your Routine

We understand that when you’re not feeling well, oral hygiene might seem like a low priority. However, maintaining your dental care during cold and flu season can actually help you recover faster and prevent additional complications. Even if you can only manage a quick brush and rinse, it’s better than skipping altogether.
