Just finished by invisalign orthodontic treatment at the Whitesmile orthodontic dental braces specialist which is in Times Square, Kuala Lumpur. I am happy with the result, but i am not sure about the retainers. They offer one which is made at their clinic and another which is from invisalign called vivera. Anyways, they are pretty good at what they do and quite a lot of my friends are doing invisalign there.
