Hello & welcome,Dry mouth
is the condition when salivary glands produce less amount of saliva in the oral cavity following any underlying pathology or disease.
Tongue sticks to the floor of mouth just because of dryness in the oral cavity & there is not enough moisture to keep it working properly.
Dry mouth is associated with administration of certain Anti-Anxiety
or Anti-histaminic drugs or it may be related to stress.
It is also seen in patients habitual of smoking or chewing tobacco.
Dry mouth should be immediately treated because it causes increased caries in teeth , Bad smelling mouth or Halitosis
