When cold and flu season hits, most of us focus on getting rest, staying hydrated, and fighting off symptoms. But have you considered how being sick affects your oral health? The truth is, illness can take a significant toll on your teeth and gums, making dental care during cold and flu even more important than usual.
How Illness Affects Your Teeth
Being sick creates several challenges for maintaining good oral health. Dehydration and dry mouth are common side effects of illness that reduce saliva production. Since saliva naturally cleanses your mouth and neutralizes acids, having less of it leaves your teeth more vulnerable to decay. Additionally, mouth breathing—especially when you’re congested—further dries out your mouth and can contribute to bad breath when sick.
Sinus pressure can also create a confusing situation where your upper teeth may ache, even though there’s nothing wrong with them. This referred pain is completely normal, but it can make maintaining your oral care routine uncomfortable.
The Hidden Dangers of Common Remedies
While cough drops and liquid medicine help ease your symptoms, they can be surprisingly harmful to your teeth. Most cough syrup contains sugar and acid that coat your teeth. Similarly, many cough drops are essentially hard candies that bathe your teeth in sugar for extended periods. Whenever possible, choose sugar-free lozenges to minimize the risk of cavities.
If you must use sugary medications, try to rinse your mouth with water afterward and avoid taking them right before bed when saliva production naturally decreases.
Vomiting and Acid Erosion
If your illness involves vomiting, you’re exposing your teeth to stomach acid, which causes enamel damage and acid erosion. Here’s an important tip: Should I brush my teeth after throwing up? The answer is no—at least not immediately. Wait to brush after vomiting for at least 30 minutes. Brushing right away can actually spread the acid around and cause more harm to your already-softened enamel.
Instead, rinse your mouth with water or a baking soda rinse (one teaspoon of baking soda in a cup of water) to neutralize the acid. A saltwater rinse also works well to cleanse your mouth gently. After waiting 30 minutes, you can practice gentle brushing to clean your teeth without damaging the enamel.
How to Take Care of Your Teeth When You Have the Flu
Protecting teeth when sick doesn’t have to be complicated. Here are some practical steps for maintaining oral health when sick:
- Stay hydrated by drinking plenty of water throughout the day to combat dry mouth
- Rinse your mouth with water after taking medications or using cough drops
- Continue brushing twice daily, even when you don’t feel well
- Use a soft-bristled toothbrush for gentle brushing if your mouth feels sensitive
- Replace your toothbrush once you’ve recovered to avoid reinfecting yourself
- Choose sugar-free medications and lozenges when possible
- Keep a humidifier running to add moisture to the air and reduce mouth breathing
