It is possible that the severity of the underbite may make it much harder to eat your food, but it is more likely you have developed strategies for getting by. Tearing food with your incisors (4 upper and lower front teeth) may be more difficult, as to treatment, if done correctly you should use your new mouth ideally. Go for it!
