I have a receding chin and deep overbite. The overbite is minimal, but I think the deep bite is pretty bad. I visited a dentist who said braces could correct it, but I've had braces before for a gap between my front teeth, which first caused my teeth to bend inwards and then returned within a year (I just get the gap filled now). I read about mewing and have been trying it out (lot of difficulty getting the posterior third up), but I don't know if it'll help in my case. And if so, whether it should be used alongside or after getting orthodontic help for my deep bite.
