I got invisalign braces put on a couple days ago. My teeth are almost perfect they just started to shift and I need to correct some issues, especially on the bottom. I've been doing alright with them but my number one issue is this slight lisp that I have. I am constantly giving talks and speeches and I need to be able to speak freely. I'm not sure if the lisp will go away or not but I'm having a hard time with it. I'm thinking I'll need to remove the upper tray when I'm giving talks sometimes.
