Cold and flu season can take a toll on your entire body, and your mouth is no exception. While you’re focused on recovering, it’s important to remember that being sick affects your oral health in ways you might not expect. At Dominion Smiles, we want you to know how to protect your smile even when you’re under the weather.

When illness strikes, several factors can compromise your dental health. Dry mouth becomes a major concern because many medications reduce saliva production, which is your mouth’s natural defense against bacteria. Dehydration from fever or vomiting further compounds this problem. Additionally, mouth breathing—common when you’re congested—dries out your oral tissues and creates an environment where harmful bacteria can thrive.

The Hidden Dental Dangers of Being Sick

Understanding how illness affects your teeth helps you take better preventive measures. Here are some common threats to your oral health when sick:

Acid Erosion from Vomiting

If you’re dealing with stomach flu or vomiting, your teeth are exposed to stomach acid, which can cause significant enamel damage. Many people wonder, “Should I brush my teeth after throwing up?” The answer might surprise you: wait at least 30 minutes. The acid temporarily softens your enamel, and immediate brushing can actually cause more harm. Instead, try a baking soda rinse or saltwater rinse to neutralize the acid first.

Medications and Sugar Content

Cough syrup and liquid medicine often contain high amounts of sugar, which feeds harmful bacteria in your mouth. Cough drops can be equally problematic. Whenever possible, choose sugar-free lozenges to soothe your throat without compromising your teeth.

Dry Mouth and Bad Breath When Sick

Reduced saliva production leads to dry mouth, which not only feels uncomfortable but also contributes to bad breath when sick. Saliva helps wash away food particles and bacteria, so when production decreases, bacteria accumulate more easily.

Dental Care During Cold and Flu: Best Practices

Taking care of your oral health when sick doesn’t have to be complicated. Here’s how to take care of your teeth when you have the flu or a cold:

Stay Hydrated

Drinking plenty of water is crucial for both recovery and protecting teeth when sick. Water helps stimulate saliva production and washes away bacteria and sugar residue from medications.

Practice Gentle Brushing

Continue your regular oral hygiene routine, but consider gentle brushing if you’re experiencing sinus pressure or tender gums. Use a soft-bristle brush and be thorough but not aggressive.

Replace Toothbrush After Illness

Once you’ve recovered, replace your toothbrush to avoid reinfecting yourself with lingering germs. This simple step is an important part of dental care during cold and flu season.

Use Protective Rinses

A saltwater rinse or baking soda rinse can help neutralize acids and maintain a healthier pH balance in your mouth. These rinses are especially helpful after vomiting or taking acidic medications.

When to Seek Professional Help

If you experience persistent tooth pain, sensitivity, or enamel damage from illness, don’t hesitate to reach out to Dr. Ruiwen Ma at Dominion Smiles.
