Permanent human teeth are numbered in a boustrophedonic sequence. Most teeth have identifiable features that distinguish them from others. This information serves a practical purpose for dentists, enabling them to easily identify teeth and structures during treatment. [35] Like any other bone in the human body, alveolar bone is modified throughout life. [52] The incorporated fluoride makes enamel more resistant to demineralization and thus more resistant to decay. A technique for altering the natural progression of eruption is employed by orthodontists who wish to delay or speed up the eruption of certain teeth for reasons of space maintenance or otherwise preventing crowding and/or spacing. Well, for once they are wrong. For human teeth to have a healthy oral environment, enamel, dentin, cementum, and the periodontium must all develop during appropriate stages of fetal development.
