When cold and flu season hits, most of us focus on getting plenty of rest, staying hydrated, and managing our symptoms. But have you considered how being sick affects your oral health? At Cottage Hill Dental Care, Dr. Mohammad Al-Asadi wants you to know that illness can take a real toll on your teeth and gums—and a few simple strategies can help protect your smile while you recover.

How Illness Affects Your Teeth

You might wonder: Does being sick affect your oral health? The answer is definitely yes. When you’re battling a cold or flu, several factors can compromise your dental health. Dehydration and mouth breathing (often caused by congestion) both lead to dry mouth, which reduces saliva production. Since saliva naturally helps wash away bacteria and neutralize acids, having less of it leaves your teeth vulnerable to decay and can contribute to bad breath when sick.

Additionally, sinus pressure from congestion can actually make your upper teeth feel sore or sensitive. This happens because your sinuses sit right above your upper tooth roots, and inflammation can press on nerve endings.

The Hidden Dangers of Common Cold Remedies

Many cold and flu remedies can inadvertently harm your teeth. Cough drops often contain as much sugar as candy, creating an acidic environment that promotes tooth decay. Cough syrup and other liquid medicines frequently have high sugar content and low pH levels, contributing to acid erosion. Whenever possible, opt for sugar-free lozenges and take liquid medications at mealtimes rather than right before bed.

Protecting Teeth When Sick: Practical Tips

Good dental care during cold and flu season doesn’t have to be complicated. Here are some practical ways to maintain oral health when sick:

Stay Hydrated

Drinking plenty of water helps combat dry mouth and keeps saliva flowing. This is one of the simplest yet most effective strategies for protecting teeth when sick.

Rinse Regularly

A saltwater rinse or a baking soda rinse can help neutralize acids in your mouth and soothe irritated tissues. Mix a teaspoon of salt or baking soda in warm water, swish gently, and spit out. Do this several times a day, if needed.

Practice Gentle Brushing

Continue brushing twice daily, but use gentle brushing techniques if your gums are sensitive. Don’t skip your oral hygiene routine just because you’re under the weather.

How To Take Care Of Your Teeth When You Have The Flu

If your illness involves vomiting, special precautions are necessary. Should I brush my teeth after throwing up? This is a common question, and the answer might surprise you: wait to brush after vomiting. Stomach acid softens tooth enamel, and brushing immediately afterward can cause enamel damage.

Instead, rinse your mouth thoroughly with water or a baking soda rinse (one teaspoon of baking soda in a cup of water). This helps neutralize the acid. Wait at least 30 minutes before gentle brushing with a soft-bristled toothbrush.

When To Seek Professional Care

Sometimes illness can trigger genuine dental emergencies. If you experience severe tooth pain, a knocked-out tooth, or a dental abscess while sick, don’t wait to seek emergency dental service at our Elmhurst office.

After You Recover

Once you’re feeling better, replace your toothbrush to avoid reinfecting yourself with lingering germs. It’s also a great time to schedule a routine dental checkup to ensure your teeth weathered your illness without any lasting damage.

Taking care of your smile doesn’t stop when you’re under the weather. If you have concerns about how illness has affected your oral health, call Cottage Hill Dental Care at (630) 530-7998 to schedule an appointment with Dr. Mohammad Al-Asadi.
