How does tooth decay begin?

Teeth begin to decay slowly. Only a series of mistakes that people make during hygiene, refusal of dental services, portend the inevitable loss of a tooth. The tooth may bleed at first. This, first of all, indicates the sensitivity of the gums. Then an unpleasant smell appears. Teeth stains that look like food debris. Enamel is damaged, partial destruction of enamel occurs, bone tissue is destroyed (this provokes severe pain). The tooth is crumbling in whole or in part. The first step is to prevent decay and save the tooth.
