Xerostomia disrupts the normal
saliva balance in the mouth, which
leads to a number of oral and dental
disorders such changes in taste,
speech, and the ability to eat in addition
to increasing the risk of cavities
and infections [7]. Xerostomia also
causes mouth tissues to become inflamed
and sore, which in turn can make
chewing, tasting and swallowing difficult
and possibly lead to difficulties
in controlling diabetes because of a
reduced interest in eating and thus, an
inability to properly maintain stable
blood sugar levels.
