inglés?

Splint?

Depende del contexto.

It could be a splint but it could also be those "removable casts"

the one your dentist ask you to wear if your teeth chatter.

@Robin: you can try to be more explicit and describe what you specifically want to know, so you will get an accurate answer instead of guesses. :)

dental splint


dental guard (cheaper version, without the dentist visit) :)
