How many permanent teeth does an adult dog have?

• A. 42
• B. 40
• C. 46
• D. 44

Answer: (A)

Permanent teeth in an adult dog total 42. This standard set is distributed with 20 teeth on the upper jaw and 22 on the lower jaw. Puppies start with 28 baby teeth, which are gradually replaced by the adult teeth as they grow, usually by about 4 to 7 months of age. The full dentition includes incisors, canines, premolars, and molars, all working together to aid tearing, shredding, and grinding food. While 42 is typical, some dogs may have fewer due to tooth loss from disease or injury, but 42 is the common adult count.
