Once the tooth has erupted into full occlusion, that is, it meets the opposing tooth in the opposite arch, there is no more growth of the tooth itself. However, fully erupted teeth can move and shift depending on a number of factors. For example, if the opposing tooth or any adjacent tooth is removed, the tooth can shift as it seeks a new equilibrium (all opposing forces being equal). In the case of the opposing tooth being removed, the tooth can 'super-erupt' and move toward the opposing space. In extreme cases the tooth can actually work (grow) out of its socket if it does not meet some opposition to stop it. If a tooth is in malocclusion (bad relationship to other teeth) it can shift and move in such a way that it appears to be 'growing' but this is not actual growth. The tooth is the same size, it may just appear larger because more of it is visible relative to other teeth.
300 psi, or 1000 on a specific tooth that is not in occlusion
The opposite arch, or set of teeth. So for example if they say extract a first molar tooth on the upper arch but it may cause over-eruption of the opposing tooth in the opposing arch, it means the first molar tooth but in the lower arch.
The area of the tooth where the cementum meets the enamel is called the cementoenamel junction or CEJ for short.
The loss of tooth structure by mechanical forces from opposing teeth.
a ratio where each tooth to tooth contact is different each time. one tooth does not contact the same tooth more than once per revolution
The section of the tooth where the anatomical crown meets the anatomical root is called the cementoenamel junction (CEJ). This junction marks the transition between the enamel covering the crown and the cementum covering the root.
High spot-- An area of a tooth or restoration that feels abnormal or uncomfortable because it hits its opposing tooth before other teeth meet.
The apex of a tooth is the tip of the root where nerve and blood supply enter the tooth through the root canal. It is located at the bottom of the tooth, in the area where the tooth meets the jawbone.

Molar width refers to the width of a molar tooth in the mouth. It can vary based on individual anatomy, with the average adult human molar width being around 9-11 mm. Molar width is important for determining tooth alignment and occlusion in the mouth.
Retraction cord is primarily used when the margin of the crown (where it meets natural tooth structure) will be below the gumline. If the point at which the crown meets the tooth is above the gumline, cord is not generally used.
