Teeth have been feeling uncomfortable. it feels like i have saliva stuck above gums and i can't get rid of the feeling. any idea?

Saliva/gums: It could be decay, it could be a gum or tooth infection, it could be you just need to have your teeth cleaned. In any case, there is no way to make a diagnosis without a clinical and visual exam, and additional information. Make an appointment to see a dentist for a thorough examination.

Plaque: It might be plaque adhering to your teeth. When was the last time you have a professional cleaning? Your dentist should take a look.
