If you’re looking for the best dentist, this is where you’ll find him. Dr. Lee Gause is exceptionally skilled, professional, and genuinely cares about his patients. He takes the time to explain everything, makes you feel comfortable, and delivers outstanding results. It’s rare to find someone who combines such expertise with such a caring approach. I wouldn’t trust my dental care to anyone else. Highly recommended!

Dr. Gause and team — thank you for an outstanding year of care. Over the past year, I’ve worked with your office through an implant, whitening, and Invisalign teeth straightening, and the experience has been exceptional from start to almost finished. The entire staff is professional, friendly, and truly best-in-class. Every visit felt like walking into a polished, professional environment with a warm welcome. I was always greeted with engaging conversation (and even offered a bottle of water), the wait times were consistently short, and I never once felt rushed during any appointment. Dr. Gause and the team took the time to explain each step clearly and made the whole process comfortable and confidence-boosting. If you’re considering implant work, whitening, or Invisalign, I couldn’t recommend Dr. Gause and his team more highly. Thank you to the entire team! Best, Marc Keller Ps. Will follow up with phots next month. :)
I’m really delayed writing this review, we’ve been traveling so much. I went to Smile dental in January and had a wonderful experience. I started the process of a root canal and everything went incredibly well. Being a couple of months post procedure, I’m still pretty comfortable. My husband and the owner were even able to connect over Opera, as my husband is a producer. We live in SEAsia so it’s really important to us that I get back to Smile dental to complete the process but overall, I loved my initial visit. The staff made it even more enjoyable as everyone was so welcoming. I would highly recommend this dental office to anyone in the NYC area. If we resided in NYC, this would certainly be our permanent, long term dental care team.
This was my first of many appointments with this business. Dr. Gause and his staff was excellent, very professional, personable etc. Dr. Dr. Gause was by far the best doctor of any kind I've visited. He cares about clients. The work is outstanding and the office is warm and inviting. You won't be sorry trust me. I'm scheduling my next appointment right away.
Smile Design Manhattan is amazing!!!!! Rachel at the front is friendly and lovely. Dr. Meyers is the sweetest and so happy I met her. Samantha was so caring, knowledgeable, fun and patient and a beacon of professionalism. Everyone in the office is so nice and I am starting my Invisalign journey with them and I can’t wait to post before and after photos!
