From John Mamutil:
The Colour My Braces app is a fun application designed to let you choose colours of the O-ring Modules that hold Orthodontic wires to your braces.These O-rings are changed intermittently or when wires are changed or progressed.Choose bright Fluoro colours for Summer or match them with the clothes that you are wearing. Perhaps even for that special occasion like a formal or a wedding.The Invisalign button means ... well, no braces, so it takes you to our Invisalign site.Use the app to send your colour selection to us by email, ahead of your appointment.
