In infants and children it is
common to observe strips of tissue extending
from the oral mucosa to the tissues near the
teeth. These are called frena and are located
in the upper jaw, midway between the two front
teeth. They should be pink, thin, and firm,
with smooth borders.
The tissue next to the teeth is
called the gingiva (gums, Figure 5). It should
be pink and should form a tight, smooth collar
around each tooth. It should be moist and not
spongy. If pressed, it should not bleed. During
the transition from primary to permanent teeth,
the gingiva may have rolled edges.
