Researchers have found the two-stage therapy that starts early to treat prominent front teeth does not appear to have any advantages over one phase treatment.

The study involved eight trials and a total of 592 patients.

“Prominent upper front teeth may be due to many different combinations of jaw, tooth and lip positions. Without treatment the teeth can become damaged over time, but it appears that there is no harm done in waiting for early adolescence before starting treatment,” say lead authors Jayne Harrison, MD, a consultant orthodontist who works at Liverpool University Dental Hospital, UK and Professor Kevin O’Brien from the University of Manchester.
