Why Mouthwash is Essential for Fighting Halitosis
What Causes Bad Breath?
Bad breath, or halitosis, often stems from bacteria that thrive on food debris in your mouth. When these bacteria break down protein molecules, they release sulfur compounds that smell foul.
Other factors include dry mouth, gum disease, smoking, and certain foods like garlic or onions.
How Mouthwash Works
Mouthwash can kill bacteria, neutralize acids, or coat the tongue to reduce odor. Some contain essential oils, while others use chemical antiseptics.
Choosing a mouthwash with proven antimicrobial properties is key to tackling halitosis.
When to Use Mouthwash for Best Results
- After brushing and flossing, to reach areas brushing misses.
- At least 30 seconds, not just a quick rinse.
- Preferably in the evening, before bed, to curb overnight odor.
