d have to assume that most of those people have been to the dentist,
and many have had some kind of
dental work done, and not gotten any symptoms.
If you've never gotten an outbreak, it doesn't mean you will now, if you even have it. This isn't something I'd worry about at all. If you end up with an outbreak, you can try suppressive therapy, like daily valtrex or acyclovir, at least for the duration of your braces.
