Dental hygiene

Dentists once believed that toothbrushing alone helped prevent dental decay. Opinion soon changed when they found the chief culprit was a bacterial film called Plaque that formed round teeth and gum margins. Normally invisible, Plaque is startlingly revealed by using special crimson‐stained disclosure tablets; without correct and regular brushing of teeth and gums, precious molars can loosen, decay, and be lost for ever.
