I didn't get my impressions right so we just did a free scan at the office. It was easy and actually very interesting. You get to see a camera go over each tooth so I actually saw the inside of my mouth on a screen. Then they showed me my teeth and how they bite down on the screen. It was crazy to see how my teeth had moved over the years since I had braces as a kid. The whole experience was easy and actually really interesting. The staff was incredibly nice and they give you free teeth whitening stuff.
