Which condition is characterized by a painful dental lesion in cats?

Feline tooth resorption is characterized by the painful erosion of a cat's teeth, often leading to significant discomfort. This condition typically affects the structure of the tooth, where the enamel and dentin begin to break down, resulting in lesions that may expose sensitive areas of the tooth. Cats with this condition often show signs of pain, such as reluctance to eat, drooling, and changes in grooming behavior, as well as possible visible lesions in the oral cavity.

In contrast, while gingivitis and periodontal disease can also cause discomfort, they primarily involve inflammation and infection in the gum tissue and surrounding structures rather than direct lesions on the teeth themselves. Malocclusion refers to misalignment of the teeth and does not directly lead to painful lesions. Understanding these distinctions helps in recognizing the specific nature of feline tooth resorption and its impact on a cat's oral health.
