Is vertigo or dementia a possible cause of my not being able to hear out of my left ear? i can't hear out of my right ear as if i were descending on a flight to land but my ear never pops so the hearing hasn't come back

Hello. : Hello. You may have some dysfunction of your eustacian tube (that tube that connects the inside of the ear with the throat). This could be causing the sense of pressure in your ear and the reduction in hearing. Vertigo is more like a sense that things are spinning around you - or sometimes that things seem tilted. There is a disease in which a person can have episodes of vertigo with intermittent hearing loss. You might want to try an oral decongestant. Afrin nasal spray can be helpful but must not be overused. It should not be used more than twice a day for 3 to 5 days (it only works for me for about 48 hours). As for dementia, i don't see how that would fit in with ear pressure with decreased hearing. Hope this resolves quickly. If the problem becomes worse or is not resolving, get in touch with your doctor.
