Q. Hi, i’m 18 and i had braces for 2 years when i was 13. since then i havent had any trouble until recently when my lateral incisor has felt slightly loose. this was one of the teeth which moved the most during my orthodontic treatment. in the past few weeks it has felt slightly painful in what im assuming is the root. i have noticed it has moving so i’ve had to wear my retainers every night nd they feel tight around this tooth whenever i put them in. is this normal? i have also read that these sort of symptoms can be related to sinus problems, is this likey? i did mention that my tooth felt loose to my dentist but he said it was about 0.5 on the scale of looseness and not to worry, did he miss something? generally my teeth are healthy and i have not noticed any abcesses.
