I had my attachments put on a couple of weeks ago. I have to say, it is a form of torture. I am not really sure why they are calling them attachments. What they are is just some clear bonding material baked onto the teeth in random shapes. Mine definitely do not look like the perfectly squared ones that you see in all the pictures around the web. Who knows - maybe mine are a special case, although my teeth do not look half as bad as what I've seen out there.
