Ameloblasts are cells in the enamel organ which forms the tooth. They secrete [[Enamel - Anatomy & Physiology|enamel]].

*Synthesises [[Enamel - Anatomy & Physiology|enamel]] which forms the [[Crown - Anatomy & Physiology|crown]] of each tooth

*Maintains connections with the newly synthesised [[Enamel - Anatomy & Physiology|enamel]] through cellular projections called Thomes' fibres

*Maintains connections with the newly synthesised [[Enamel|enamel]] through cellular projections called Thomes' fibres

*[[Enamel - Anatomy & Physiology|Enamel]] is acellular so once the connection with the ameloblasts via the Thomes' fibres is lost (upon eruption), [[Enamel - Anatomy & Physiology|enamel]] matrix cannot be remodelled
