Pre-gingival or cervical caries of teeth is diagnosed when the destruction of hard dental tissues affects a part of the tooth near the neck - a slightly narrowed transition of the dental crown to the root, that is, near the very edge of the gum, and often even under it.
A disproportionately large or abnormally wide tongue - macroglossia, as a rule, occurs in children and is considered a fairly rare anomaly. Macroglossia usually means prolonged painless enlargement of the tongue.
A deep bite associated with improper closing of the teeth can adversely affect the function of chewing, speech, lead to increased abrasion of the enamel coating, etc. With some degrees of such a violation, treatment should be mandatory.
