As you can tell this show is completely ridiculous and I don't think my write-up about it is much better.

I don't really know what you meant by that statement because it has nothing to do with your explanation on this comic series.
Everyone has a way of passing his message to the world, Ren and Stimp are trying to do just that in the way they know best.

There is an episode where Ren won't brush his teeth and ends up with just nerve endings and he has to pluck those for some reason.

The way the message was presented might be wired, but the message is clear enough, if you leave your teeth un-catered for, it won't be long before they would be removed.
