The long axis of a tooth refers to an imaginary line that runs vertically through the center of the tooth, extending from the tip of the root to the top of the crown. It serves as a reference point for various dental procedures and assessments, helping to determine the orientation and position of the tooth in relation to adjacent teeth and the overall dental arch. Understanding the long axis is crucial for accurate diagnosis, treatment planning, and performing procedures such as extractions or restorations.

"Long in the tooth" is a colloquialism which means "old" or "worn out". It is derived from the idea that elderly people and some animals such as horses and dogs tend to experience gingival recession as they age. The gums tend to recede up the tooth, exposing more of the tooth, hence, 'long in the tooth'. Anything that is considered old fashioned, outdated or overused can be called "long in the tooth".
