When you’re under the weather, brushing your teeth may not be top of mind—but it’s one of the best things you can do to feel a little more like yourself. A clean mouth can actually help you feel better and support your body’s recovery. During cold and flu season, it’s especially important to take care of teeth, even while you rest and recover.

Here are some simple ways to protect your oral health while you’re sick:

1. Keep Brushing & Replace Your Brush When You Feel Better

Sticking to your brushing routine is important, even when you’re feeling crummy. Germs from illnesses like the flu can linger on toothbrushes for up to 72 hours, so never share your brush—even with family members. After you’ve recovered, go ahead and replace it, especially if it’s more than three months old.

To reduce bacteria between uses, disinfect your toothbrush by soaking it in hydrogen peroxide for a few minutes after brushing.

2. Choose Cough Drops That Are Kind to Your Teeth

Many over-the-counter cough drops are packed with sugar, which feeds cavity-causing bacteria in your mouth. Sucking on them is like keeping a piece of candy in your mouth all day.

Instead, choose sugar-free cough drops, especially those with xylitol, a natural sweetener that actually helps fight cavities. Avoid ingredients like corn syrup and fructose when possible.

3. Wait Before Brushing After Vomiting

If the flu brings nausea or vomiting, resist the urge to brush immediately. Stomach acid coats your teeth, and brushing right away can spread that acid, damaging your enamel.

Instead, rinse with water or a mix of water and baking soda, then wait about 30 minutes before brushing to protect your teeth from erosion.

4. Watch Out for Dry Mouth

Cold and flu medications, like decongestants and antihistamines, often cause dry mouth, which can increase your risk of cavities. Keep water nearby and sip throughout the day to stay hydrated. Sugar-free lozenges or mints can also help stimulate saliva and keep your mouth more comfortable.

5. Drink Smart

Water is always your best option, both for your body and your teeth. If you’re drinking sports drinks to replenish fluids, go for sugar-free versions and avoid sipping them throughout the day.

For comfort, herbal teas can help, but skip the sugar and lemon if you can. Sugar feeds bacteria, and lemon’s acidity can weaken enamel.
