Great when others have a lisp from something new. I really like that.
Strangely, with mine, I was really self-conscious about a lisp when I first got to wear plates and thought that it was obvious to everyone, which made me stumble over my words. After a couple of days I recorded myself and realised that nothing was noticeable.
For me, I like to know that I have the plates in and feel them but I like that I have learned to talk and eat with them and nothing is noticeable. Its like they are part of me and, in fact, I can probably say S's a bit clearer with them in than without.
