The Carvalho and Roth Smile Formula

We create beautiful, healthy smiles in a fraction of the usual time

We focus on every aspect of your smile to get you the best bite and the most aesthetically pleasing smile possible.


Smile Arc is an aesthetically pleasing smile
where the upper teeth follow the contour
of the lower lip.


Smile VME gets rid of that “Gummy Smile”
and shifts the bite into the correct position and
make the gums appear less prominent.


Broad smile refers to an
“ear to ear” smile that gives you
a more youthful appearance.

    I have had the pleasure of working with Heather at the front desk over the course of the last year and she has been nothing but accommodating and helpful. I would highly recommend Carvalho and Roth Orthodontics!

  • I had my Invisalign done with this office. Overall it was such an easy experience. They don’t use molds to make the trays - they use a digital scanner which is so much better than what I had as a kid. My treatment took 8 months and my teeth look perfect again. This office is super easy to work with and took care of all my insurance papers so I got my benefit and I didn’t have to do anything.

    My time at Carvalho & Roth was great! The doctors always listened to my questions and concerns and used the best approach to my treatment, the staff always friendly with a smile in their face. Thank you so much for helping me to achieve the smile that I wanted.
