Driving me nuts for years, but I watched a movie probably 25 years ago that was really weird. All I remember is:
I'm pretty sure it was British or some other European film.
There was a town that was on the other side of a bridge that was cloaked in a fog and zombie like creatures lived there.
There was a scene where an older couple lived in a house and the older woman was brushing her teeth and they started falling out, and the older man told her that her breath smelled like death and she started screaming and crying.
At one point there was a person or two people that ran out of the bridge and the zombie creatures things were throwing crab apples, or rocks or something at him.
I'm pretty sure the final scene had the person running down to a road, and a person passing by stopped and picked him up. He was trying to escape, but the car took him back over the bridge into the foggy town and the ending scene just showed the zombie like people clawing at the car eerily.
