Retainers are for maintaining teeth in position, hence called retainers. To move teeth we use active appliances like clear aligners, braces, and spring clip appliances. Your case will likely require IPR or interproximal reduction to reduce the width of the lower front teeth to align them again without needing to reconfigure your bite. I would recommend aligners to retreat your concerns. then you can wear retainers to bed to maintain your amazing smile.
