When you’re feeling under the weather, brushing and flossing might be the last thing on your mind. However, illness can have a significant impact on your oral health—sometimes in ways you may not expect. At Dorset Dental in Scarborough, we often see patients dealing with dental issues that began during or after being sick.
Let’s break down how common illnesses affect your teeth and gums—and what you can do to protect your smile.
The Hidden Connection Between Sickness and Oral Health
Whether it’s a cold, flu, stomach virus, or even chronic illness, your oral health can take a hit in several ways:
1. Dry Mouth (Xerostomia)
Many illnesses—and the medications used to treat them—reduce saliva production.
Saliva is essential because it:
- Washes away bacteria
- Neutralizes acids
- Helps prevent cavities
Without enough saliva, your risk of tooth decay increases significantly.
2. Increased Risk of Cavities
When you’re sick, you might:
- Sip on sugary drinks (like juice or sports drinks)
- Use cough syrups or lozenges high in sugar
- Snack more frequently
This constant exposure to sugar feeds bacteria, leading to tooth decay and enamel damage.
3. Vomiting and Acid Erosion
If your illness involves vomiting (like a stomach bug or morning sickness), stomach acid can:
- Weaken enamel
- Increase tooth sensitivity
- Lead to long-term erosion
Important Tip: Avoid brushing immediately after vomiting. Instead, rinse with water or a fluoride mouthwash and wait 30 minutes before brushing.
4. Gum Inflammation
Your immune system is already working hard when you’re sick, which can:
- Make gums more sensitive
- Increase inflammation
- Lead to bleeding when brushing or flossing
This can worsen or trigger gingivitis if oral hygiene slips.
5. Neglected Oral Hygiene
Let’s be honest—when you’re sick, routines fall apart.
Skipping brushing and flossing for even a few days can:
- Allow plaque buildup
- Lead to bad breath
- Increase the risk of cavities and gum disease
How to Protect Your Teeth When You’re Sick
Even small steps can make a big difference:
- Stay hydrated (water helps maintain saliva flow)
- Brush twice daily with fluoride toothpaste
- Rinse your mouth after taking medicine or vomiting
- Choose sugar-free medications when possible
- Replace your toothbrush after recovering (to avoid reinfection)
