The Dental Enamel And The Anatomy Of The Tooth


  
  The enamel portion of the tooth is an extremely hard, highly mineralized, non-cellular material that gives the tooth its cosmetic properties and the hard, wear-resistant surface. The enamel and its’ cosmetic characteristics are formed at the time the tooth develops within the jaw. Enamel, the hardest substance in our body, is 96% mineral, and is non-regenerative and non-reparative.

  Dental enamel is highly concentrated with  Hydroxylapapitie mineral, a  calcium phosphate crystallin, providing its' hardness. The combination of high concentration of the hydroxlapatite and lack of collagen fibers unfortunately also makes enamel very brittle. Both bone and Dentin contain the collagen fibers giving bone and dentin much greater flexibility.

  These characteristics of enamel are significant in that heavy wear and grinding, and any decay, is highly damaging to the tooth strength and its cosmetics.  Although a little enamel loss is tolerable, significant loss will require dental restoration to protect the remaining tooth structure and protect it from the oral environment.  The mineralized nature of enamel gives the tooth its unparalleld hardness in the body and its beautiful natural biosethetic qualities seldom matched in nature.
