Why do I need to rinse my mouth after using my inhaler?

Rinsing with water and spitting after using a corticosteroid inhaler is crucial. It washes away any medication residue from your mouth and throat, which significantly reduces your risk of developing oral thrush (a fungal infection).

Can my asthma inhaler cause cavities?

Indirectly, yes. Many inhalers can cause dry mouth, which reduces your saliva's natural ability to protect your teeth, increasing your risk for cavities. Some inhaler powders are also acidic, which can contribute to enamel erosion.

What is the best way to manage dry mouth from my inhaler?

Stay well-hydrated by sipping water throughout the day. Chewing sugar-free gum or using over-the-counter saliva substitutes can also help stimulate saliva flow.

How Asthma and Its Treatment Can Affect Your Mouth

Dry Mouth (Xerostomia)

The Cause: Many asthma medications, particularly beta-agonist inhalers, can reduce saliva flow. Also, people with asthma are more likely to breathe through their mouth, which further dries out the oral tissues.
The Impact: A dry mouth significantly increases the risk of tooth decay and gingivitis, as saliva is essential for washing away food and neutralizing acids.

Oral Thrush (Candidiasis)

The Cause: Inhaled corticosteroids can disrupt the natural balance of microorganisms in the mouth, allowing the Candida fungus to overgrow.
The Symptoms: This appears as creamy white patches on the tongue and inside of the cheeks.

Increased Risk of Enamel Erosion

The Cause: Some inhaler powders are acidic. When used frequently, they can contribute to the erosion of tooth enamel, making teeth more sensitive and prone to decay.

Tips for Protecting Your Oral Health with Asthma

Rinse After Inhaling: Always rinse your mouth with water and spit it out immediately after using your corticosteroid inhaler.
Stay Hydrated: Drink plenty of water throughout the day to combat dry mouth.
Use Fluoride: Use a fluoride toothpaste and consider a fluoride mouth rinse to help strengthen your enamel.
Inform Your Dentist: Make sure your dentist knows you have asthma and what medications you take.
