The teeth start the process of digestion by breaking food down into pieces small enough to swallow. Teeth also give shape to the face and help us to pronounce sounds when we speak.
We grow two sets of teeth in our lifetime. The first set, the milk teeth, start to emerge from a baby’s gums at about six months or age. Then from six years, the second set of permanent teeth starts to emerge. At the same time, the roots of the milk teeth are absorbed by the body, so the teeth become loose and eventually fall out.
With the lips and tongue, teeth help form words by controlling airflow out of the mouth. The tongue strikes the teeth or the roof of the mouth as some sounds are made.
When we eat, our teeth tear, cut, and grind food in preparation for swallowing.
