Mouth feels dry 2 hours after meals

Hi, the dentists out there, I'll like to know if it's normal that my mouth feels dry about 2 hours after eating. Female, 52, menopausal. Only on HRT, no other meds that could cause dryness.

Is it 'dry mouth' when the sides of the mouth are still moist? I see dryness mostly on the root of the mouth (especially the back part), back of mouth leading to throat, and inside of upper and lower lips (dryish to the touch). Tongue has white coating (not thrush) and fissures though.
