I never tried invisalign myself but my orthodontist did (and still) offer it. He's Dr. Ritchie Mah
Burnaby Metrotown Orthodontist | Ritchie Mah DDS | Metro Pointe Orthodontics BC V5H 4M4 The building is across the street from Staples at Metrotown.
Granted, this was 15-16 years ago when he was my Dr but he did a wonderful job on both my brother and I. I still see him once in awhile when we bump into one another at dimsum (he's a younger guy..probably in his 40's now...well..I guess "younger" is subjective) and he still remembers us. Our family dentist still refers their patients to him as well. Not that this is important but since I'm giving a small review...the office was Clean and up to datewhen I was there, so I'm sure he still keeps it that way.
Just wondering, is getting braces an option? Or are you very firm on the idea of invisalign?
