After 2 1/2 years wearing braces , my granddaughter had them taken off recently, only to find that she had numerous cavities in her bottom teeth. She is getting them filled...but.my question is.......was it just due to poor brushing? Or was it due perhaps to other things ...such as not using fluoride toothpaste...or not getting enough calcium in her diet......or she has soft teeth? She is very embarrassed about this and upset about not cleaning her teeth enough.........but worse yet is that her mother is shaming her in front of others....which is not right... Does anyone have experience like this or thoughts to help her feel better about herself?
