My girls braces were remved 6 mnths ago noticed that 1 tooth shifted and they were unable to fix with adjust retainer. She wore her's all the tim so did not happen because she didn't wear them. Had to fight to get him to fix w/out rechrg for braces again. I paid 6,000 with braces/expander. Is it right tht he will only allow her 6 months for teeth to correct and then begin charging me 100.00 there after if nec. Is this really how it shoud behandled. Pls adv me i feel this is really bad bus. Thnks
