Denta Stix - good or bad?

I brush the poodle's teeth every night, one side each night. Then she gets either a greenie or a dentastix. She has Addison's Disease, is on steroids, so a dental procedure would require anesthesia and be pretty risky. So far the vet is very happy with her teeth and so are we. I started training the puppy to get his brushed when he was four months old. No issues with either of them swallowing large pieces of greenies or dentastix. However they do occasionally get bully sticks and we have to take the last few inches away from the puppy or he will swallow it.
