...frenillos.
 

What does it mean to sacar los frenillos?
:thinking:I thought maybe frenillos might have to do with frenos, but I´m not sure...:confused:

The frenillos are in the teeths.

It's when the doctor remove you the frenos of the teeths.

To take out one's braces = sacar los frenillos

Crotalito's post was probably good enough to make you think about braces, but I thought it better to not mince words.

That brings to mind the term retainer, the device used to support the teeth after you get your braces taken out. Any ideas on how to say that in Spanish?

The following file says it is el aparato de retención.

Unfortunatelly, guys, I'm an expert because I wear braces myself(which will hopefully be taken out in a month or a couple of months:)). Retainers are called retenedores. But don't get me started because just thinking of dentists makes me shiver...:yuck: Anyway, let's look on the bright side, after two long years I will soon have the smile of a Hollywood star...:rose::rose::rose:(por cierto, ¿ conocéis la expresión echarse flores?... es un poco como lo de no tener abuela).
Frenillo here in Spain is something different, it's a small membrane we have under the tongue (frenum in English) which in some people is abnormally short resulting in a speech defect.

And the word for braces in Spain is also different. We say aparato.

Well, three of my kids still do.
What´s the meaning of the expression you mentioned?

aparato
 

Seems like "aparato" it a catch all word for just about anything, anytime there is a mechanism without a specific word...:thinking:

Have a look here.
