Lee, Young & Ubaldo Orthodontics

I'm doing invisalign after my dentist expressed concerns about my bite and (like yours) said my front tooth could eventually break off.  Unlike you, however, I also REALLY care about how teeth look.  Call me shallow, but I think it's the single most important thing about your appearance - more than clothes, more than shape, more than hair.  If you have good teeth, you look younger, smarter, and wealthier! Invisalign definitely works, and it's a little annoying but not painful.  Also, it promotes good dental hygiene because you brush more frequently. As your teeth straighten, it becomes a lot easier to floss, too (at least in my case it has).  My orthodontist (Rodney Lee in SF) is really good, and it was less expensive than I expected.   

You do have to keep wearing the retainers at night if you want to avoid your teeth moving back to the way they were.  This is a common problem with kids - my son had braces but didn't wear his retainer when he was done, and now his teeth need straightening again.  SIGH.
