What Bill said.
Raw fed dogs usually have good dental health without the aids of dental chews and routine cleanings. I dislike putting my dogs under and aim to avoid it.
Non raw fed dogs, usually, do not have excellent dental health through a lifetime, unless provided with safe chews daily (RMB’s), and have owners diligent with tooth brushing.
A correct bite and a strong root structure plays a part, as our raw fed pet with a terrible bite and a terrible root structure often times have issues despite RMB’s, but it’s more rare than the regular dog with a sound bite/root structure eating kibble and chomping down Greenies.
No matter what we feed, when we evaluate a pup we look for a good bite. Parents must have a good bite, or at least the bitch if the sire is off site. When teeth fit together well, good dental health usually follows. When the jaw is over or undershot, poor dental health usually follows….with kibble fed dogs/cats, it’s a few years (or months with the little guys), with raw fed dogs, it’s a few years and (in our experience) less intense even with the little guys. It depends on so many factors.

I’ve seen dogs eat dental chews, Greenies, Denta-stix, CET chews, and they chomp off 1/3 of the chew, chomp, swallow, chomp off another 1/3, chew once, swallow, and then swallow the rest of the chew whole.
I cannot fathom how that does a damned bit of good for their dental health.
Our dogs plow through RMB’s and huge hunks of rubbery tripe and it takes them a good bit of time to do so. Their teeth are gorgeous.
Can I see what’s going on behind their gumline? Of course not. But I can’t see what’s going on behind the gumline of my own teeth and I can’t look inside my own body and detect cancers or organ malfunction, etc….
Sometimes, common sense prevails.
