- "It wasn't a pretty sight. Hermione's front teeth — already larger than average — were now growing at an alarming rate; she was looking more and more like a beaver as they elongated, past her bottom lip, towards her chin — panic-stricken, she felt them, and let out a terrified cry."
- —Description[src]
Densaugeo[2] was the incantation of a hex[3] which caused the teeth to elongate at an alarming rate.[1][2]

History

The effects of this hex
During the 1988–1989 school year at Hogwarts School of Witchcraft and Wizardry, this hex was taught to fifth year Defence Against the Dark Arts students by the then Professor of the subject Patricia Rakepick.[3]
Hermione Granger was hit by this hex from Draco Malfoy's wand. Draco and Harry had begun fighting in the corridor, which eventually led to a duel, but the spells they cast at each other missed and hit Hermione and Gregory Goyle instead.[1]
In September 2020, an adult Draco Malfoy used this hex again at Harry Potter during his duel with him in Harry's house, although Harry missed being hit by the spell.[5]
Known practitioners
Etymology
The incantation is derived from Latin "dens", which means "tooth", and "augeo", which translates to "increase" or "grow".
