The upper first premolar typically erupts before the upper canine due to the sequence of tooth development and the timing of eruption. Premolars generally emerge earlier in the dental arch as part of the transition from primary to permanent teeth, while canines usually take longer to develop fully. This staggered eruption pattern is influenced by the growth and spacing of the jaw, allowing the premolar to establish its position before the canine emerges. Additionally, the functional roles of these teeth in chewing and alignment also dictate their eruption timing.

what do molar teeth do
The first premolar, also known as the first bicuspid, is typically the fourth tooth from the midline in each quadrant of the mouth. In adults, it is located between the canine and the second premolar. The first premolar usually has two cusps and is primarily used for grinding food. In the upper jaw, it often has a slightly larger and more prominent structure compared to its lower counterpart.
There are two types of sharp cutting teeth. The first is the Canine (a.k.a. cuspid) and the second is the premolar. However, the canine is the most commonly referred to as the cutting tooth.
I believe you are refering to the "canine teeth" Definition of Canine Tooth: a conical pointed tooth ; especially :one situated between the lateral incisor and the first premolar
The maxillary first premolar
Yes
The upper first premolar has Mesial Marginal Developmental Groove in its mesial aspect. It also has long central groove and no supplement groves on its occlusal surface.Also 80% of the upper premolars have 2 roots. However, the upper second premolar has no MMDG and many supplemental groves. Upper second premolar is more rounded and usually has one conical root.
