roof of mouth
Tongue's upper boundary
The roof of mouth is the upper interior surface of the mouth, separating the oral cavity from the nasal passages.
The hard palate forms the front portion; the soft palate extends toward the throat.
Peanut butter famously sticks to it: The bread stuck to the roof of my mouth.
