About House of Orthodontia - Manhattan

Dr. Thomas Lien is described fixing complicated overcrowding and long-standing open bites with Invisalign, often skipping extractions and laying out timelines upfront.

Dr. Thomas Lien treats a wide range of cases, from routine alignment to complicated overcrowding and long-standing open bites, often using Invisalign or retainers instead of extractions. Reviews mention early treatment for young children and several families bringing multiple siblings through the practice at once. A handful of reviews note that Invisalign treatment took longer than expected, sometimes tied to mid-treatment transfers or pandemic-related delays.

I can’t recommend Dr. Lien enough! He is genuinely one of the kindest and most thoughtful dentists I’ve ever worked with. I got my Invisalign treatment done with him, and he takes the time to make sure you fully understand every procedure, including the process, cost, and expected results. He never makes you feel rushed and his post-care was also incredible. I recently went back to him, 3 yrs later, for some corrections that were unrelated to his original work, and he was still happy to help. He took the time to understand what I wanted and made sure I got the best possible result. The administrative side of the practice is also very easy and seamless. Everyone in the office is welcoming, professional, and genuinely pleasant to interact with. I’m grateful to have found Dr. Lien and his team, and I would highly recommend him to anyone!

Our son has been with House of Orthodontia since grade school. The doctors have been kind and very good at what they do. I love their all inclusive flat fee. From getting an expander to braces and now beautiful teeth, our son was definitely a regular customer and is now a satisfied "graduate". Thank you!

I have nothing but good things to say about House or Orthodontia. They’ve been so accommodating to my needs and gone above and beyond with making my teeth something I’m proud to show off. I highly recommend to anyone looking for a good Invisalign provider.
