Persistent bad breath, especially in the morning or after eating, is very common and highly manageable. I recommend looking for alcohol-free mouthwashes containing active ingredients like cetylpyridinium chloride, zinc formulations, or chlorine dioxide, which neutralise odour-causing compounds. Additionally, daily use of a tongue scraper is highly effective at removing bacterial buildup. Brush twice daily with a fluoride toothpaste containing antibacterial agents like zinc citrate. Sugar-free gum or mints containing xylitol can help by stimulating saliva flow to naturally cleanse your mouth. If this persistent halitosis continues despite these steps, please see a dentist to rule out gum disease or dental cavities.
