Oral mucosa is dry and sensitive, prone to injuries, fungal infection and inflammation,
painful with burning sensations, taste is altered and halitosis is present.

glands become visibly enlarged. These initial changes may precede clinical evidence
of mucosal changes or measurable reduction in salivary gland function
