Q.
I have just been fitted with an invisalign brace, with the hope of shifting my lower front teeth to fill a gap where I lost a tooth. I am very unhappy with the aligner because it is very uncomfortable (a sharp bit of plastic digs into the underside of my tongue) and I have found it difficult to sleep. And now, having read some of the Q&As on this site, I see that you do not recommend the invasalign system for shifting teeth (I currently have a gap right at the front). Is this correct – and should the aligner be more comfortable?
