Which species is more likely to develop tooth resorption?

• A. Dogs
• B. Cats
• C. Horses
• D. Rabbits

Answer: (B)

Tooth resorption in cats is a common and distinctive dental problem. In felines, odontoclastic resorption lesions—often called feline odontoclastic resorptive lesions—are frequently seen and can affect many teeth as cats age. These lesions typically start near the cementoenamel junction and progressively destroy hard tooth tissue, causing pain and often necessitating extraction. Because cats show a much higher prevalence of these resorptive lesions than other species, they are the most likely to develop tooth resorption.

In dogs, horses, and rabbits, resorption occurs far less often or is not the typical dental issue seen. Dogs and horses more commonly deal with periodontal disease or other dental problems, while rabbits tend to experience malocclusion and overgrowth rather than resorption.
