Explanation:
The plaque that is formed in the teeth is a highly anaerobic bacteria but it can sustain in the environment rich in oxygen. The oxygen is used by the bacteria and there is a absence of oxygen in the teeth.

It basically uses the oxygen available in the mouth and makes the condition anaerobic.

good luck!
