Mouth Breathing and Increased Plaque

Mouth Breathing and Increased Plaque

Mouth breathing subjects show a significant 4 times higher risk to develop Streptococcus mutans (S. mutans) and an increased level of plaque index (PI). Plaque is a sticky substance from leftover food particles. A build up of plaque is not good for dental health and can cause gum disease.  

The group of mouth breathers may retain a greater amount of bacteria in their mouth, possibly due to the evaporation of water from the saliva of constant mouth breathers.
