hello and welcome,
you are suffering from halitosis.this caused by accumulation of plaque and food debris around teeth.
the no.of times you brush your teeth does not matter.always brush your teeth in correct method-ie,in down to up and up to down manner.hold the toothbrush in 45 degree angle .
visit your dentist
and get a deep scaling done to remove the hard calcific deposits of plaque called calculus.
also check the salivary secretion.the plaque accumulation will be more in case if the salivary secretion is more mucous in nature.streptococcus
sanguis,s.mitis,s.mutans,and actinomyces viscosus are usually present micro-organisms in plaque.
if there is gingivitis and bleeding gums
associated,then take tab.microdox.100mg,once daily for 3 days.
use soft interdental brush
and tongue cleaner to clean your teeth.the listerine which is a chlorhexidine gluconate
containing mouthwash will help to remove the micro-organisms in the mouth.
