If you repeatedly bite your tongue or cheek, you may have malocclusion of the dentition that is contributing to this painful situation. Typically, the shapes of the tooth surfaces facing the tongue (lingual) and cheeks (buccal) are such that, when the teeth are positioned correctly, the tongue and cheeks are guided safely away from the biting area. If this is not the case, orthodontic treatment may be advisable. Both children and adults suffer from this problem and can be successfully treated in most cases. Advancement in orthodontics (e.g., wire technology, Acceledent, TADs, Invisalign, etc . . .) makes such treatment shorter in duration than in years past and appropriate for all ages.
