Nobody enjoys being sick, but have you ever considered how illness affects your teeth? Cold and flu season brings more than just sniffles and body aches—it can also take a toll on your oral health. At Magical Smiles in Plainfield, Dr. Vineet Sharma, DDS, wants you to understand how being sick affects your oral health and what you can do to protect your smile during recovery.
How Illness Challenges Your Oral Health When Sick
When you’re fighting off a cold or flu, your body goes through changes that can impact your teeth and gums in several ways:
- Dry Mouth: Dehydration and mouth breathing (especially when congested) reduce saliva production, which normally helps wash away bacteria and neutralize acids
- Acid Erosion: Vomiting exposes your teeth to harsh stomach acids that can weaken enamel
- Medication Side Effects: Cough syrup and liquid medicine often contain sugar that feeds cavity-causing bacteria
- Sinus Pressure: Inflammation in your sinuses can cause tooth pain and sensitivity in your upper teeth
Essential Tips for Dental Care During Cold and Flu
Stay Hydrated Throughout Your Illness
Drinking plenty of water helps combat dry mouth and keeps saliva flowing. This is crucial for protecting teeth when sick because saliva acts as your mouth’s natural defense system. If plain water doesn’t appeal to you, try warm herbal tea or broth to maintain hydration levels.
Choose Sugar-Free Options
When reaching for cough drops or lozenges, always select sugar-free lozenges. Traditional cough drops can be as damaging as hard candy, constantly bathing your teeth in sugar. The same principle applies to liquid medicine—rinse your mouth with water after taking cough syrup to minimize sugar exposure.
Should I Brush My Teeth After Throwing Up?
This is one of the most common questions about how to take care of your teeth when you have the flu. The answer might surprise you: wait to brush after vomiting for at least 30 minutes. Here’s why—stomach acid temporarily softens your enamel, and brushing immediately can cause enamel damage. Instead, use a baking soda rinse or salt water rinse to neutralize acids and freshen your breath. Mix one teaspoon of baking soda in a cup of water, swish thoroughly, and spit.
Practice Gentle Brushing
When you’re sick, your gums may be more sensitive. Use gentle brushing techniques with a soft-bristle toothbrush. If you’re experiencing bad breath when sick, don’t be tempted to brush more aggressively—this can irritate already-sensitive tissues.
Replace Your Toothbrush After Recovery
Once you’re feeling better, replace your toothbrush immediately. Your toothbrush can harbor bacteria and viruses, potentially reinfecting you or spreading illness to family members.
When to Visit Your Dentist
Most oral health issues related to illness resolve on their own, but severe or persistent symptoms warrant professional attention. If you experience prolonged tooth pain, especially related to sinus pressure, or if you’ve had repeated vomiting that you’re concerned may have caused acid erosion, contact our office for an evaluation.
