Well, dental hygiene and any other kinds of hygiene is not necessary to put in an adventure story. We simpy assume it was done. If Tolkien had put every little detail into action, there would be a lot of unnecessary writing. It's obvious that, for example, when the Fellowhip was walking the wilderness they would have to relieve themselves etc. Maybe the threat of Sauron dampened the need to wash ones hair etc.
It was simply done, but there was no reason to write how it was done.
Interesting thread, by the way.
