Acid production by bacteria.

-Dental caries is caused by acids produced by specific microorganisms in the plaque.

 

-Intake of sugar induces a rapid pH drop in dental plaque producing a variety of acids.

 

-This pH drop may last for varying periods of time depending upon a number of factors. The buffering systems return the pH back to normal within 20 minutes to an hour.

 

-This drop in pH produces demineralization of the tooth structure.

Preventive measures:

-Limit sugar intake.

 

-Chewing sugarless or Xylitol containing gum after sugar intake will aid in the rapid buffering of the acids produced from the sugar intake.
