DH had an open bite that was left untreated as a child b/c his parents thought it was just cosmetic. By age 35, he could only eat soft food and only 4 teeth touched! His TMJ was so bad he would miss work regularly.
$30,000.00 surgery (thankfully insurance covered 80%) 3 months of painful recovery, and $5000 braces later, DH is a new man! Yes, he looks bit different, but his was LONG gone, and quite frankly, symmetry always looks better :D.
His parents could have prevented it all. They feel rotten now...but they just didn't know :grouphug:.
DD9 has a palate expander now, DS8 will get his this summer. DD says it is annoying, but not painful. ;)
