I`ve been wearing lingual braces for 2.9 years now. My teeth became straight but my smile totally disappeared and ruined. I can hardly see my upper teeth even when I smile broadly. My upper teeth went somehow up and maybe back. Before braces I could see my whole front teeth and part of the gym when broadly smiling. My lower teeth became taller comparing before braces. I have two upper molars extracted for the treatment. My orhto doesn’t know why this happened with my smile. I`m 30 years old.
