Hasta los dientes literally translates to "up to the teeth". It's a classic Spanish idiom used to express that something is done to an extreme degree, similar to the English phrase "armed to the teeth".
In the song, Camila Cabello gives it a unique twist, singing "Me duelen hasta los dientes" (Even my teeth hurt). She uses this dramatic, over-the-top expression to describe the intense emotional pain her jealousy is causing, making it a powerful and unforgettable line.
Ever been so into someone that thinking about their ex makes you feel physically sick? That's the whole mood of this super fun pop track from Camila Cabello and Maria Becerra. It's a song about being completely obsessed with a new partner, but also being tortured by thoughts of their past. The singer admits she's crazy, saying, "Yo estoy loca, pero loca por ti" (I'm crazy, but crazy for you), and she can't stop imagining him with his old flame.
This isn't just a little bit of jealousy, it's a full-on obsession that hurts. She sings, "Me duelen hasta los dientes" (Even my teeth hurt), which is such a dramatic and funny way to describe the pain. She wants him all to herself, declaring, "No te quiero compartir, te quiero sólo pa' mí" (I don't want to share you, I want you only for me). Even his kisses make her sad, because she knows he's kissed someone else the same way. It's a relatable feeling taken to the extreme, all wrapped up in a song that will make you want to dance.
