So ever since I had braces as a teen I still have these small metal threads behind my teeth to keep them in place or something. It's just glue and a thread. Yesterday I got something between my teeth and the thing broke so I called the dentist. Just went there expecting to them just replace the thing, I sort of remember this happening once before. And they guy was like yeah okay you have this and this option like a night brace and blabla and I asked can't you just replace the thing. Ok an appointment next week for a scan and it has to be measured and then in two weeks it can be reapplied. So I was like wait what? It is just a thread and he got all insulted like "yeah you call it that but it's called a brace and it needs to be carefully measured" etc etc. I wasn't even being rude or anything, just asking some simple questions. I made an appointment at the desk and the lady was also kind of rude for no reason. What in the absolute fuck is going on. Am I being scammed?
