Similar Assertions

Treating gum disease helps increase beneficial bacteria in the gums but doesn't significantly change the bacteria on the tongue.

92%

People with gum disease have fewer mouth bacteria that help convert nitrate to nitrite compared to people with healthy gums.

91%

Using mouthwash that kills mouth bacteria leads to higher levels of nitrate in both saliva and blood.

76%

After gum disease treatment, harmful bacteria decrease in both the gums and the tongue.

74%

Bacteria in the mouth help keep nitrite levels in the blood stable, which is shown by the fact that people with higher nitrite in their saliva also tend to have higher nitrite in their blood.
