During a physical examination, when the lip is pulled up, can you see the maxillary 10s as they curve inwards?

When the lip is pulled up during a physical examination, you can indeed observe the maxillary canine teeth (often referred to as the maxillary 10s) as they curve inward. This is due to their anatomical position and orientation in the maxilla (upper jaw).

The maxillary canines play a critical role in both occlusion and the alignment of the dental arch. Their unique conical shape and slightly angled position create the characteristic inward curve when the lips are elevated. This visibility is important for assessing the health and alignment of these teeth, as well as for identifying any potential dental issues such as malocclusion or periodontal disease.

In summary, the statement is true, as the anatomy of the maxillary canines allows for their visibility during a dental examination when the lip is retracted.
