Most pets don’t floss. Accept it. Nor do they brush. There are times that their breath can clear a city. Mouth odor is usually from gum disease. It’s pollution that, like the Hudson river, requires cleaning up.
Dental procedures demand anesthesia, usually with preanesthetic blood testing for reducing anesthetic risk. Teeth are cleaned, polished, sometimes extracted. Breathe is as soft as a autumn breeze. Maybe not. We have even done orthodontics, but that’s another story.
