 When first researching orthodontics, ancient Egypt seemed to be a starting point for dental alterations. When exploring the idea further, we came across the lotus shape which in Ancient Egypt holds a meaning of rebirth and reincarnation. In Buddhism it symbolizes "victory of the spirit" and in Hinduism it is related to spirituality and beauty. We thought this connected well to the conversation about gaining self esteem. The marks shape also lends itself to a blooming motion or "blooming" confidence.
