Is he an angora with his head hair recently trimmed, or a mix for the long fur is only on his body?! He looks like Jon Snow, wearing the large fur cape haha.

Yellow v. White teeth would really only tell you if a rabbit is less than or more than 6 months old. Wick’s teeth haven’t been white since 6mo! Wick’s teeth are bad though, so they kinda look gross regardless, but I’ve seen other people on the forum post about non-white teeth and typically it’s always common, no matter the age.

Is this vet one you’ve been to before? Are they heavily experienced with rabbits?

I used to think teeth color was the best determination of age as I had been told after 5 years, the teeth yellow. But as you have already discovered, that is not always the case.  Young rabbits can have yellow teeth and older rabbits can have whiter teeth.  So it’s not as dependable as I used to think.  

This is a really great video by a HRS rep and vet – talks about a couple of different ways to tell.   I found it very interesting that you may be able to tell via the hocks!    https://www.youtube.com/watch?v=pp2Y-9nTZUc

Rabbit have enamel. Their enamel is white-ish, like humans. Rodents, on the other hand, have dark yellow (sometimes almost orange) enamel.

How yellow are we talking here? I don’t think any rabbit has snow white teeth. They start out fairly white when they are young and grow a little darker with age. But as BB pointed out, age isn’t the only factor contributing the tooth color. I believe genetics has something to do with it. Certain types of food (if they are consistent in the diet) may contribute as well.
