The black stain, which is most often seen near the gum line on on both the front and back of the teeth of children, is the result of the action of chromogenic bacteria.
Eruption hematoma (Eruption cyst)
A bluish purple, elevated area of tissue, commonly called an eruption hamatoma, occasionally develops a few weeks before the eruption of primary and permanent tooth.
Thumb, Finger and Pacifier Habits
Many children suck their thumbs or fingers for short periods during infancy or early childhood with the habit considered normal during the first 2 years of life.
Children exhibit teeth grinding very commonly. We see it in children younger than 7-8 years old often. A lot of children will stop grinding once their six-year permanent molars erupt.
