The parotid duct (Stensen's duct) opens into the vestibule of the mouth opposite which tooth?

• A Upper first molar
• B Upper canine
• C Lower second premolar
• D Upper second molar ✓

Explanation

The parotid duct emerges at the anterior border of the gland, crosses the masseter, turns medially at its anterior border, pierces buccinator and opens on a small papilla in the vestibule opposite the crown of the upper second molar. The submandibular duct, by contrast, opens on the floor of the mouth beside the frenulum, so confusing the two glands is the classic distractor error here.
