Q. I had braces in when i was 16 and up until recently they have maintained their position. I also had a permentent bar behind my 2 front teeth which prevented a gap, but as the bar broke my 2 front teeth have started to part again and have moved forward. I went to a free consultation re invisable braces and was told that it would cost £1900!! for one deck!! is this my best option or should i opt for the cheaper version of train tracks? which do you think would be best and work quicker? would it be cheaper if i was refered by a dentist rather than refering myself if i went for the train track options??
