I am wondering if a random orthodontist would intervene in the care of you childs braces, but maybe ask your ortho to see what they think. Both my boys have them and early on dealt with numerous wires breaking simply due to the initial thin wire used. We had wire breakage almost weekly until they figured out they can not play with the wire. We had a few late nights of having to remove the wire because it snapped. Thankfully my husband had braces and knew what to do. A few days without a wire is not a huge deal. If you are only down there a week, you might just be advised to bring something to help with cutting the wire or removing a portion if they break. Then just dealing with it when you return home. Hopefully by the time you go they will be in a thick enough wire that breakage will not be an issue (we have been doing great since moving up in wire size). Brackets are less likely to be an issue (maybe have them checked before you go), but if so i wouldn't worry about spending the time at an ortho for a bracket replacement while on vacation. A couple days is not going to be a big set back in the over all care. I'll be interested in what you get for replies/info/recommendations or others experiences with this.
