|If you think about the logistics and mechanics of the chewing, neither the nylabone nor the antlers will cover large parts of the teeth or up to the gums, so I'd say they're good to pass the time, but not for dental hygiene. There needs to be a degree of softness for the meat/bone to reach all the teeth all over yknow? I notice with my own dog when she chews her antler it makes no difference to her teeth, but after chewing on a chicken leg or pork ribs her teeth will be white and sparkly.
Any kind of bone is good really, but as a previous poster said, be wary of weight-bearing bones from heavy animals (any animal heavier than my dog is my limit - chicken and rabbit's fine) - they're the hollow, marrow-filled ones. The knobby ends are cartilage and good for chewing, but the actual bone is hard as hell, and will damage teeth if the dog gnaws too much at it. Lots of dogs will just eat the marrow out though, and then you can re-use the bone and stuff it like a kong. Recycling!
Teeth are also really hard so be careful with chewing on skulls.
Also, the younger the animal, the softer the bone. My dog can fairly easily chew weight-bearing bones from a lamb, but I wouldn't give her the same bones from a grown sheep.
I've also heard - this is entirely anecdotal, mind - that the nylabone is as hard as a weight-bearing bone, and has damaged dogs' teeth.
