There are numerous typical symptoms that characterize xerostomia (dry mouth), leading to a significant reduction in quality of life for those affected. The following symptoms and complaints may indicate xerostomia:
- Dry mucous membranes – oral mucosa is atrophic, reddened and sensitive to pain.
- Sticking of the tongue to the mucous membranes; tongue surface occasionally shows indentations and cracks
- Viscous saliva
- Dry, cracked lips
- Taste disorders (dysgeusia)
- Chewing difficulties – when eating dry food.
- Dysphagia (dysphagia/swallowing difficulties) – when swallowing empty.
- Chewing difficulties – when eating dry food.
- Burning tongue (glossodynia)
- Burning mouth (stomatopyrosis; bourning-mouth syndrome, BMS).
- Bleeding gums and tongue
- Tongue surface reddened, strongly furrowed; possibly also indentations and cracks.
- Teeth: after years of dry mouth, they may be decayed or demineralized
- Pain when speaking, chewing and swallowing.
- Strong bad breath (foetor ex ore)
Denture wearers complain of poorly fitting dentures due to the lack of or reduced saliva film suction adhesion.
Other symptoms/diseases may include:
- Caries – due to the lack of saliva is also lost its protective effect on the tooth hard substances, so that increased caries occurs.
