Cold and flu season can take a real toll on your body, but did you know it can also wreak havoc on your smile? When you’re feeling under the weather, maintaining your oral health when sick might be the last thing on your mind. However, understanding how illness affects your teeth and taking a few simple precautions can help protect your smile during recovery.
How Being Sick Impacts Your Teeth and Gums
Does being sick affect your oral health? Absolutely. When you’re battling a cold or flu, several factors can compromise your dental health. Dehydration and dry mouth are common culprits, as many people don’t drink enough fluids when they’re not feeling well. Your body needs extra hydration to fight off illness, and when you’re dehydrated, saliva production decreases. Since saliva is your mouth’s natural defense against bacteria and acid, reduced saliva flow leaves your teeth more vulnerable to decay and creates an environment where bacteria thrive.
Mouth breathing, especially when you have a stuffy nose, further dries out your mouth and can contribute to bad breath when sick. Additionally, sinus pressure can cause discomfort in your upper teeth, as the roots of these teeth sit close to your sinus cavities. While this tooth pain usually resolves once the sinus infection clears, it’s still worth monitoring.
The Challenges of Medications and Symptoms
Protecting teeth when sick becomes even more important when you consider what you’re consuming to feel better. Many common remedies can harm your enamel:
- Cough drops and lozenges: Most contain high amounts of sugar that coat your teeth, feeding harmful bacteria
- Cough syrup and liquid medicine: Often acidic and sugary, these stick to tooth surfaces
- Citrus-based vitamin C supplements: The acid can erode enamel over time
Whenever possible, opt for sugar-free lozenges and rinse your mouth with water after taking liquid medications. If vomiting is part of your illness, the stomach acid that comes into contact with your teeth can cause significant acid erosion and enamel damage.
Best Practices for Dental Care During Cold and Flu
How to take care of your teeth when you have the flu doesn’t have to be complicated. Here are some practical strategies:
Stay Hydrated
Drinking plenty of water is crucial. Stay hydrated to maintain healthy saliva production, which naturally cleanses your mouth and neutralizes harmful acids. Keep a water bottle nearby and sip throughout the day, even if you don’t feel particularly thirsty.
Should I Brush My Teeth After Throwing Up?
This is a common question, and the answer might surprise you. You should wait to brush after vomiting—ideally at least 30 minutes. Stomach acid temporarily softens your enamel, and brushing immediately can actually scrub away this weakened layer. 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 and soothe irritated tissues.
Practice Gentle Brushing
When you do brush, use gentle brushing techniques. Your gums may be more sensitive when you’re sick, so don’t scrub aggressively. Continue brushing twice daily and flossing once daily if you can manage it.
Replace Your Toothbrush
Once you’ve recovered, replace toothbrush heads to avoid reinfecting yourself with lingering germs. This is an important but often overlooked step in staying healthy.
