Hi Mark. I had lingual braces on 2 weeks ago and I am using lots of wax but my teeth feel like they have razor blades stuck in between them that are ripping my tongue to shreds and I am lisping badly. I am a 51 year old female and am totally regretting my decision. It cost an enormous amount of money and now I do not want to go out in public as I constantly lisp and I am always aware of it. I regret not doing more research, I had no idea it would be so painful. Any advice?
