When I got my wisdom teeth removed, they used a slightly bigger needle for the local anesthesia. Usually, when they work on cavities or whatever, they use a very thin one, but that one was noticably bigger and kinda hurt. Then I went to get the stitches removed, and they had a syringe with an even bigger needle lying around! It turned out that they just used it as a dispenser for something, I forgot what it was, but it was scary to see that huge needle xwx
