Dr. Cheng: Growing up with Misaligned Teeth

Dr. Cheng didn’t always have a straight set of teeth.

Growing up, he suffered from teeth misalignments with a space between his upper left canine and premolar as well as lower front teeth that were crooked. Yet, he didn’t consider fixing his teeth until university where he learnt about the different types of misalignments.

In 2014, after hearing comments from some patients regarding his misaligned teeth as a young dentist himself, he decided to undergo Invisalign treatment.

His Invisalign journey spanned 9 months and it allowed him to gain many unexpected insights that he wouldn’t have known without this first-hand experience. This allowed him to better understand patients’ concerns and also improve their overall experience through his own tips and tricks!


“During my treatment, I realised that I had to carry several items to store and clean the aligners. So I came up with the idea of an Invisalign pouch for my patients. It’s a handy pouch that contains chewies, a pulltool, aligner file, toothpaste and an aligner case. It’s really convenient for patients since everything they need is already prepared for them.”Dr. Cheng
