Microbes damage teeth by forming a hard, off white colored substance called plaque. Plaque causes gum disease which will make the teeth bad if not treated in time.
Dental plaque is, well, bacterial excrement (ie: pooh). It is a biofilm that covers teeth and builds up as a yellow calculus that covers the base of teeth or the whole tooth if left untreated. Plaque is bad because it releases acids that degrade the teeth, acts as a barrier to the natural movement of saliva (which remineralises teeth) and as stated builds up as a hard yellow calculus (tarter). also you suck
