Winter brings more than just chilly temperatures—it’s also prime time for colds and the flu. While you’re focused on recovering from congestion, sore throats, and body aches, your oral health when sick might be the last thing on your mind. However, understanding how illness affects your teeth and maintaining proper dental care during cold and flu season can make a significant difference in protecting your smile.

How Being Sick Impacts Your Mouth

Does being sick affect your oral health? Absolutely. When you’re under the weather, several factors can compromise your teeth and gums:

Dry mouth is one of the most common issues. Dehydration from fever, reduced fluid intake, and certain medications all decrease saliva production. Since saliva naturally washes away bacteria and neutralizes acids, having less of it leaves your teeth more vulnerable to decay and can contribute to bad breath when sick.

Mouth breathing often occurs when nasal congestion forces you to breathe through your mouth, which further dries out your oral tissues and reduces protective saliva.

Vomiting from the flu exposes your teeth to stomach acid, leading to acid erosion that can weaken your enamel and cause sensitivity. This is one of the most damaging aspects of how illness affects your teeth.

The Hidden Dangers of Cold Medications

Many people don’t realize that common remedies can harm their teeth. Cough drops typically contain high amounts of sugar that coat your teeth. Opt for sugar-free lozenges whenever possible. Similarly, cough syrup and other liquid medicines often contain sugar and acids that can damage enamel, especially when taken repeatedly throughout the day and night.

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

Protecting teeth when sick requires some adjustments to your normal routine:

– Stay hydrated: Drinking plenty of water combats dry mouth, helps flush bacteria, and supports your immune system
– Use a saltwater rinse to soothe irritated tissues and reduce bacteria naturally
– Try a baking soda rinse (one teaspoon in warm water) to neutralize acids in your mouth
– Practice gentle brushing if you’re experiencing sinus pressure or sensitivity—your teeth and gums may feel more tender when you’re ill
– Take your medications with meals when possible to minimize prolonged acid exposure

Should I Brush My Teeth After Throwing Up?

This is a crucial question for anyone experiencing vomiting. The answer might surprise you: wait to brush after vomiting. Stomach acid temporarily softens your enamel, and brushing immediately can cause enamel damage. Instead, rinse thoroughly with water or a baking soda rinse, wait at least 30 minutes, then brush gently with a fluoride toothpaste.

Post-Illness Dental Care

Once you’re on the mend, it’s important to replace your toothbrush immediately. Your toothbrush can harbor viruses and bacteria, potentially re-infecting you or spreading illness to family members.

If you experienced persistent vomiting or neglected your oral care during illness, consider scheduling an appointment for general dentistry services. Dr. Randall K. McVey, DMD, FAGD, can assess any damage and provide care to restore your oral health.
