Which teeth are considered the corner stones of the mouth?

The canines are referred to as the cornerstones of the mouth due to their unique anatomical and functional characteristics. They are strategically located at the corners of the dental arch and play a crucial role in the alignment and function of the teeth in both the upper and lower jaws.

Canines are particularly important for several reasons. Their long roots provide stability and support to the surrounding teeth. They are equipped with a pointed cusp which assists in tearing food, making them essential for the process of chewing. Additionally, because of their position, canines serve as a guide during jaw movements, helping to establish an efficient occlusion and protecting the more delicate incisors from excessive wear.

In contrast, molars, while significant for grinding food, do not have the same corner support function. Incisors are critical for cutting food but are less stable and cannot provide the same level of support. Premolars, while also involved in chewing, do not play as pivotal a role in defining the dental arch's corners or guiding jaw movement. Hence, the anatomical features and functions of canines solidify their status as the cornerstones of the mouth.
