💡 Grammar Points
Masculine Plural
Even though it refers to something you have many of, the word 'dientes' is always masculine (el diente), so it uses 'los' (los dientes) and not 'las'.
Possession Trap
Unlike English, Spanish usually avoids using possessive words ('my,' 'your') for body parts; instead, use 'el,' 'la,' 'los,' or 'las.' (e.g., 'Me lavo los dientes' means 'I wash my teeth').
❌ Common Pitfalls
Using 'Mis'
Mistake: "Voy a cepillar mis dientes."
Correction: Voy a cepillarme los dientes. The reflexive verb already tells us they are your teeth, so the article 'los' is enough.
