What is the total number of teeth in the lower jaw of an adult dog?

• A. 24
• B. 20
• C. 22
• D. 26

Answer: (C)

Understanding how many teeth are in each jaw comes from the dental formula. In an adult dog, each side of the lower jaw has 3 incisors, 1 canine, 4 premolars, and 3 molars. That makes 11 teeth per side, and since there are two sides, the lower jaw has 22 teeth. For context, the typical total number of adult dog teeth is 42, with the upper jaw having 20 and the lower jaw 22. Some dogs may have variations if teeth are missing, but 22 is the standard count for the lower jaw.
