Sorry, I’ve posted this here for beauty but I’ve got no idea which forum it should go into.
My daughter must put pressure on her retainer at night. She wears it to keep her teeth from shifting after having her braces removed. She’s had them off for about 18 months, and has had to buy three new retainers at £100 a go. Is there anywhere we can buy these for cheaper, that are intended for keeping teeth from moving? I’ve found some sites on line but I’d rather go with recommendations than chose something cheap that doesn’t fit well or do the job.
