In one panel of the original manga we see the toothbrushes of everyone in the "Kaneki Crew" when they were living together, so I guess the answer to that is yes. Toothpaste probably tastes terrible to ghouls, but since most learn to fake eat human food to blend into human society, it's just another thing they have to grit their teeth and do, if only for hygiene.

As far as medical problems...it's hard to say. What sort of health problems ghouls face hasn't been explored and their physiology hasn't been explained enough to make an educated guess. The only ghouls that I can think of off the top of my head who've had some sort of health problem are Kaneki and Tooru, but they're unusual cases. Some ghouls wear glasses, which is another thing that hasn't been explained. It implies that there must be some sort of physiological issue, even if really minor.

So they can be plagued by little health problems and maybe tooth issues are possible. They probably wouldn't be able to go to a regular dentist though since their teeth are supposed to be harder than humans. I guess there could be ghoul dentists out there...
