Question

The eruption sequence for maxillary permanent teeth is ___________. central incisors, lateral incisors, first molars, canines, first premolars. In general, do maxillary permanent teeth erupt prior to mandibular permanent teeth?

Answer 1

The eruption sequence for maxillary permanent teeth is first molars, central incisors, lateral incisors, canines, and then first premolars. There is individual variation, but the eruption of lower teeth such as the central incisors generally precedes the eruption of the corresponding upper teeth.

Step-by-step explanation:

The eruption sequence for maxillary permanent teeth typically follows this pattern: first molars (emerge between 12-16 months), central incisors, lateral incisors (emerge between 12-15 months), canines (emerge between 16-24 months), and finally, first premolars. It's important to note that these ages can vary among individuals, but the sequence remains generally consistent.

In general, there is no definitive rule that maxillary teeth erupt before mandibular teeth as it can vary for each type. However, for certain teeth such as the central incisors, the lower ones typically emerge first at about six months, followed by the upper ones at about eight months.

The pattern of eruption for other types of teeth can vary and is not strictly observed to be upper before lower or vice versa. Ultimately, the pattern of eruption depends on each individual's developmental process.
