I have always concerned about how my teeth look and I need a smile makeover so badly so my friend referred me to Dr. Cheng. I had the Zoom teeth whitening thing done which only takes about an hour. I heard it could be very sensitive but it was not bad at all. Very easy procedure and it also comes with a complimentary take home kit too. I am very happy with the result. Next week I am going to start doing the Invisalign (the new clear braces). She shows me this computer illustration so I can see how the stages are done and gives an estimate of how long the process will take. It was so cool and I am so excited about it!
