Unexpectedly, yes.
I just got braces on Friday. I went with full metal and was looking forward to showing them off. Before my bracketing appointment I wasn't worried about self-consciousness at all. Over the weekend, I went out on Saturday night, ran errands, and went to church on Sunday, so lots of strangers have seen my braces. I'm finding it embarrassing to smile and talk normally without trying to hide the braces. The most embarrassing moment was, ironically, with another adult braces wearer. I feel like everyone is staring at my braces, but I know its probably all in my head. At church, though, I was sitting next to a couple in their thirties. At one point, we were greeting each other. When I shook the woman's hand, we both smiled, which revealed her full set of ceramic braces. She definitely noticed my braces, because her eyes widened, she looked directly at my mouth, then nodded her head at me and smiled bigger to make sure I noticed her braces. On one hand, it was nice, kind of like meeting another member of a secret club. On the other hand, her braces were so clear and discreet that I was struck, really for the first time, by how obvious and clunky my braces look.
The ortho put on large bite blocks on my back molars that force my jaws apart and cause a noticeable lisp. No doubt my speech will improve, but right now, people have asked me to repeat myself and my phone's voice commands are confused. When I tell the phone to "text," which comes out "tesht," the phone runs a google search for "test" instead of bringing up text messages. Go figure, as much as I've been self-conscious about the appearance of the braces, the inability to speak clearly hasn't been embarrassing at all. I'm just lisping and spitting my way through it with no shame. I guess the big metal braces make it obvious to people why I'm having a problem talking, so nobody has mentioned anything.
