Just like gnawing on a chop bone, dogs teeth won't be clean from tartar and bacteria by chewing on a bone. Large build ups may chip off but there is no substitute for a brush and paste.
The best paste and the only one I'd use has enzymes in which help break down the plaque and destroy the bacteria giving good protection over 24 hours.
SIN it is very easy to train as the toothpaste smells and tastes
Putrid great to dogs

Start with a pea sized bit on a finger and offer it as a treat for a few days. Then advance to giving it on the end of the brush ( no need for special brushes, cheap human ones will do ) . Once the dog is happy to take the paste from off the brush just lift the front bit of gum and wipe the paste on the front teeth every day. Advance each time the dog is comfortable with a stage. Go from wiping the front teeth to lifting the sides of the gums then start gradually building In the brushing motions. I always give a little bit for the dog to lick after brushing the teeth just to keep them keen and keep them thinking it is a treat.
Beforenu knowmit you should be able to lift open the mouth and brush all the teeth. Give dogs a little break in between doing a few teeth to start with. It's a slow build up but most dogs and cats get the hang of it quickly especially thinking they get away with eating a treat Thayer smells so disgusting.
Dogs that don't take to a brush can have the enzyme toothpaste wiped on the teeth. Trials have shown it still helps in breaking down the plaque and helps keep those pearlys white
