"I will miss seeing all the staff at Orthodontics of the Southern Tier when I'm done with my braces! Even after a few months go by between appointments, the staff remember things we've talked about and it makes me feel very comfortable and welcomed. They go above and beyond to accommodate any of my needs (changing appointment times, talking me through my concerns, etc.). I would recommend OOTST to anybody and their rates were better than others in the area when I was shopping around!"

Consultation First Visit: The Process

  1. You'll call us on the phone at (607) 723-9576 and we will take some information to create you as a new patient in our system and set up your free appointment at a time that works best for you. Plan to spend about an hour with us.
    New patient forms will be sent your way via email that you can fill out prior to your appointment. 
  2. On the day of your appointment you will call to check in from your car and our new patient coordinator, Jen, will come out to get you!
  3. Once you are in the new patient room, you'll get x-rays, photos, and a 3D scan done. The scan will show a simulation of how your teeth will look post treatment and give you a time estimate. Then the doctor will come in to meet you, look at your teeth, and discuss your treatment options. After that you'll discuss finances with Jen.
  4. Yay! The first visit has been completed. You can make your informed decision and get back to us. We're so excited to have you here! :)
