Dental appliances and trouser supports (6)

I believe the answer is:

braces

(Other definitions for braces that I've seen before include "They hold up men's trousers" , "Supports for men's trousers" , "Trouser support" , "Couples" , "Supports for teeth or trousers" .)

I've seen this clue in The Irish Times and the Irish Times (Simplex).
