Dogs have how many three-rooted maxillary teeth?

• A. 4
• B. 6
• C. 2
• D. 8

Answer: (B)

In canine dental anatomy, some of the back teeth in the upper jaw have more than one root to support a larger crown and to withstand chewing forces. When you tally all the maxillary teeth that have multiple roots across both sides, that count aligns with the middle option in the list. That’s why it’s the best choice: it matches the established pattern seen in typical dog dentition. Knowing which teeth have multiple roots is also clinically important because those teeth can be more challenging to extract and require careful radiographic evaluation. The other counts don’t fit the usual distribution of multi-rooted maxillary teeth.
