CET Chews are nice - there are 2 types that have different chemicals that do different things, so I'd recommend getting both types. I get mine on Amazon bc of price. One thing though - SIZE UP. DON'T get the 'petite' size - my Marcel almost died from chewing a piece off of the petites (which are more fragile than the larger sizes) and was a few seconds from choking to death.
You can also think about Healthy Mouth (VHOC approved), Wysong Denta Treat Powder, Plaque Off, PetzLife, Leba III ($$$)...and I can't recall the other available products.
I also like RMBs (raw meaty bones) for healthy, challenging chewing/gnawing. I like the Bison Back Rib bones from Whole Foods (in the Pet Freezer). And I use a few other misc chews too.
