I just want to no that is really what my ortho have said to me that I can't correct my teeth problems ( overbit, crossbit, front teeth crowding ) without damon system, unless I extract 4 teeth, I have consulted another orthodontic and asked him about damon system, he told me that I had to trust him that damon system is just a marketing tool, and so we have proceeded in the treatment until he told me that I will need teeth to be extracted! And that is not an option for me, I can't live with another face!
