Mouth Problems,Noninjury - Topic Overview
It is not unusual to have a problem with your
mouth from time to time. A mouth problem can involve
your gums, lips, tongue, or inner cheeks, the roof of your mouth (soft and hard
palates), under your tongue, your neck, or your teeth. Your mouth may be dry,

- Thrush ,
a common infection of the mouth and tongue caused by the yeast Candida albicans. Thrush appears on the mouth and tongue as
white patches that look like cottage cheese or milk curds. When the patches are
wiped away, the underlying area appears red and raw and may bleed. In babies,
thrush may cause a rash in the diaper area.

metallic taste in your mouth.
tongue may become sore or swollen, or it may change
color or texture. A buildup of food and bacteria on the tongue may make the
tongue look thick or furry ("hairy tongue"). Often the problems will
go away if the surface of the tongue is regularly brushed with a soft-bristled
toothbrush. If your tongue problem is from some local irritation, such as
tobacco use, removing the source of the irritation may clear up the tongue

allergic reaction, which can interfere with breathing.
