Category “Q. Dentistry abroad”

Please advise as to the following:
1. I understand that lingual braces can cause a speech defect eg, lisp and that this improves with time and practice. However does it disappear completely during the treatment and on average how long does this take?

2. After removal of the lingual brace does speech return to normal or is lisping defect permanent? Is there any chance that after removal speech will not return back to normal?

3. Is this treatment available outside of the UK?

Please advise me on the above questions.
