The neuromuscular theory or unification theory of tooth eruption states that the synchronized forces of the orofacial muscles, under the control of the central nervous system, are responsible for the active movements of a tooth and the molecular events prepared a pathway under the control of these forces [68,[70], [71] …

What happens to your teeth when they erupt?

After erupting, things can grow in at odd angles if there is a lack of space in the jaw and could result in dental problems. It then takes a few years for the jaws to be large enough to accommodate the final two sets of molars. In fact, most people end up taking out the final set of molars, also known as the wisdom teeth, before they even erupt.

What are the differences between teeth eruption for boys & girls?

Girls generally precede boys in tooth eruption. Lower teeth usually erupt before upper teeth. Teeth in both jaws usually erupt in pairs — one on the right and one on the left. Primary teeth are smaller in size and whiter in color than the permanent teeth that will follow.

What causes the space between primary teeth to grow in?

Shortly after age 4, the jaw and facial bones of the child begin to grow, creating spaces between the primary teeth. This is a perfectly natural growth process that provides the necessary space for the larger permanent teeth to emerge. Between the ages of 6 and 12, a mixture of both primary teeth…
