The '''odontoblasts''' are cells in the '''enamel organ''' which forms the tooth. They secrete '''[[Enamel Organ#Dentinedentine]]'''.

'''Odontoblasts''' are derived from mesenchyme and are composed of a single layer of elongated columnar cells. They are at the '''dental-pulp border'''. They secrete '''[[Enamel Organ#Dentinedentine]]''' which is a mineralised matrix of collagen I, [[Enamel Organ#Dentinedentine]] and proteins.

The first layer of [[Enamel Organ#Dentinedentine]] is formed on the enamel organ. As production increases, the odontoblasts are displaced from the [[Enamel Organ#Enamel|enamel]]. It is a major part of the tooth structure and is produced continually by the odontoblasts. The rate of [[Enamel Organ#Dentinedentine]] synthesis is increased during repair as it is innervated (but still acellular).
