I wonder if there is anyone out there that can help with some advice please. My DD is aged 11 and as a youngster had courses of antibiotics. She now gets yellow teeth and dreadful build up between her teeth, despite brushing regularly twice a day, flossing and mouthwashing. Once she goes to the dentitst for a clean up she looks great but quickly returns :( I've read juice doesn't help, so will give a straw going forward. Has anyone else had this and found a way to overcome? I was thinking of referring to a specialist?
