Depends on if you kept a log book. If you didn't, they are definitely not safe for use on teeth. You should retire them to fingernail cleaning.

I keep a log book on my belayers. That way I don't need to double them up.

Seriously though, whilst there are a few single pieces in the system, why choose to add more to the system, especially in a configuration that is going to provide nylon on nylon friction? We all agree you don't run a rope through slings because of that. In the course of self equalising, a sliding x has constant small amounts of movement and if one fails, a slide along half the length of the sling rubbing on itself. I just don't see that the slight improvement in equalisation is worth the weakening of the system overall. And I am fussy about my harness and rope as well, but they are designed and recommended for use by themselves, although we have seen what can happen when these single points fail.
