How Colds and the Flu Can Affect Your Oral Health
Posted October 27, 2024 by Dr. Brian Evans
When battling a cold or the flu, the last thing on your mind might be your oral health. However, being sick can have several effects on your mouth that you might not expect. From dry mouth to tooth pain, it’s important to understand how colds and the flu can impact your oral health and what you can do to protect yourself.
Dry Mouth and Dehydration
One of the most common issues during a cold or the flu is dry mouth. When you’re sick, you might breathe through your mouth more often due to nasal congestion, which can dry out your saliva. Saliva is important because it helps remove food particles and bacteria from your teeth. Without enough saliva, you’re more at risk for:
- Bad breath
- Cavities
- Gum disease
- Tooth decay
To combat dry mouth, make sure to stay hydrated by drinking plenty of water. Sucking on sugar-free lozenges can also help stimulate saliva production.
Cough Syrup and Sugary Medications
Over-the-counter cold and flu medications can provide relief from symptoms, but some of them may harm your teeth. Many cough syrups, lozenges, and throat sprays contain sugar, which can lead to tooth decay if not properly rinsed away. In addition, the acidity in some medications can erode your enamel, leading to increased sensitivity and potential cavities. To protect your teeth while using these medications:
- Choose sugar-free options when possible
- Rinse your mouth with water after taking medication
- Brush your teeth 30 minutes after using acidic products to avoid enamel damage
Sinus Pressure and Tooth Pain
If you’ve ever had a cold or the flu and noticed increased tooth pain, your sinuses might be to blame. The sinuses are located just above the roots of your upper teeth. When they become inflamed due to illness, the pressure can cause pain that feels like it’s coming from your teeth. This type of pain is usually temporary but can be alarming if you don’t realize the cause.
If tooth pain persists after your other symptoms have cleared up, it may be a sign of an underlying dental issue. In such cases, visiting our dental office in Reno for a thorough examination is important.
Vomiting and Tooth Erosion
During this time of year, it’s common to experience nausea and vomiting, which can be tough on your teeth. Stomach acid is very strong, and when it comes into contact with your teeth, it can erode enamel and weaken your teeth, making them more susceptible to decay. To minimize the damage after vomiting:
- Rinse your mouth with water immediately
- Wait 30 minutes before brushing your teeth to allow your enamel to re-harden
- Use fluoride mouthwash to strengthen your enamel
Taking Care of Your Oral Health During Illness
While it can be challenging to focus on oral hygiene when you’re feeling under the weather, it’s crucial to maintain good habits. Here are some tips to protect your oral health while recovering from a cold or the flu:
- Brush your teeth twice a day and floss daily
- Use a soft-bristled toothbrush to avoid irritating sore gums
- Stay hydrated to prevent dry mouth
- Replace your toothbrush after you recover to avoid re-infection
