I feel like my front teeth have undergone some kind of disuse atrophy. Whenever I try to eat something hard (eg:- Corn) it aches. I rarely use those front teeth I suppose. I use to eat fruits and other hard foods with molars and premolars after cutting it in to small pieces using knife. The lower part of the upper incisors seems translucent. What do I do to make them stronger? What kind of food do I need to take?
