My retainers continuously fit loose unfortunately. I did not experienced the pain/discomfort when moving onto new retainers and quite often after 2-3 days the retainers would fall off my teeth when talking. I had voiced my concern to ExSmile about not experiencing discomfort, they hadn’t heard that feedback before, suggesting I skip a step to move onto a tighter retainer which again after a few days was loose. I had a remake as well as utilised the additional retainer at the end of my treatment but still have the small gap in my teeth that I wanted fixed. I phoned a few times as well as emailed with questions and queries. They were always willing to help. I had a lot of hope in the treatment but sadly the treatment didn’t work for me to achieve the desired outcome and I gave up trying to chase additional retainers for treatment as they were all ill-fitting.
