Halitosis is driven by bacteria living in your mouth

Your mouth is filled with bacteria, fungi, and viruses - collectively called the oral microbiome! Some of these microbes are beneficial, while others cause damage.

Halitosis (bad breath) is driven by specific types of bacteria that live in your mouth. These bacteria produce odorous volatile sulphur compounds (VSC).

The bacteria that cause halitosis influence your oral & overall health

Your oral microbiome is associated with everything from recurrent oral infections to conditions including diabetes, heart disease & gut inflammation.

Your mouth is the gateway & mirror to your health.

The type & abundance of bacteria related to halitosis influence the severity of your symptoms and contribute to your risk for more severe oral health conditions. Tracking where you are can indicate if your oral health is improving and provide early warnings if things start to slip.

Identify what's driving your symptoms

Specific bacteria in your mouth drive halitosis and more serious conditions including gum disease & gingivitis. Understanding which bacteria you have is the first step in treating it.
