Depends what the toothpaste is. Some do have a chemical component that binds to exposed dentine e.g. Novamin in Sensodyne, but most toothpaste is just a combination of chemical substances that I don't want in my mouth any longer than necessary.
Just Google "ingredients of toothpaste and dangers". Sores, inflammation, hormone disruption, antibiotic resistance, gut bacteria imbalances, increased blood glucose levels, fluorosis, carcinogens and microplastics.
At 70, I still have very good teeth and gums so I must be doing something right.
I agree Silverbrooks.
I think Sensodyne does help but the rest, imo, is just marketing flannel. The amount of choice is ridiculous.
Some have sweeteners. I have read some Finnish research that xylitol (?) is supposed to be good for teeth. It's dangerous for dogs I know that.
Pick a taste you like and don't spend too much. I bet it's the brushing that does the good, not what we put on the brush!
