Teeth Describe Dental Caries Streptococcus Mutans Viridans Streptococci

Front Describe Dental caries
Back

• sucrose (glucose)n + fructose (makes acid) 

• (glucose)n:

― biofilm (plaque) on teeth
― adheres bacteria to teeth
― food storage 
– later broken down, makes acid

• no sucrose: cavities reduced by 90%
