These are three images of the same deteriorated teeth from different pets. Three images are presented using different backgrounds and exposure settings to accentuate the destruction to the individual teeth. The crowns of each of these teeth were descaled before extraction to spotlight the amount of calculus that migrates down roots as bone erosion progresses. Rule of rules when it comes to periodontal disease: "It ain't what you can see that will hurt you most, it's what you can't."
