Anti-odour drops may contain refreshing flavors, antimicrobial chemicals, mint, menthol, or other fragrant ingredients. Anti halitosis drops can be used to provide short-term relief, but they cannot treat the underlying causes of bad breath. If bad breath has been a problem for a long time, you should focus on improving oral hygiene, identifying and treating the root causes of bad breath. For this, it is important to consult with a dentist or doctor.
