Factors Affecting Tooth Decay

Tooth decay is a common dental problem that leads to the destruction of the hard tissues of the teeth, namely enamel and dentin. This disease is caused by acids produced by certain bacteria. These bacteria feed on sugars present in the mouth and produce acids that damage the surface of the teeth.

Foods high in sugar, such as sweets and soft drinks, play a significant role in increasing tooth decay. Additionally, consuming foods rich in starch, like chips, can accelerate the progression of tooth decay. Moreover, a deficiency of vitamins and minerals in the diet can weaken the overall health of the teeth.
