Dental caries, also known as tooth decay, is uncommon among companion animals. The bacteria Streptococcus mutans and Streptococcus sanguis cause dental caries by metabolising sugars. The term feline cavities is commonly used to refer to feline odontoclastic resorptive lesions, however, saccharolytic acid-producing bacteria (the same responsible for Dental plaque) are not involved in this condition.
