The normal temperature of the mouth ranges between 35 and 36 °C, and a two-degree (°C) change has been shown to drastically shift the dominant species in the plaque. [18] Redox reactions are carried out by aerobic bacteria. This keeps the oxygen levels in the mouth at a semi-stable homeostatic condition, which allows the bacteria to survive. [18]
