I remove my braces 1 year back. I wore braces 15 months after one year now I find my front 4 teeth move slowly slowly to old position (before braces, space between teeth from upper to lower. I wore braces in upper teeth. I consult to my dentist she said I did not wear retainer after braces treatment thats why I find space .Now I wear retainer .So it is possible retainers cover my space between teeth. Please suggest. I wear retainers after the 1 year gape between braces treatment. What can I do. Now I did not able to wear braces treatment because its expensive.
