Dental development in humans
Most human are born edentulous. A minority can be born with one or two teeth in the mouth. They are called neonatal teeth. These teeth can disrupt breastfeeding and so it may be appropriate to remove them for babies not bite the mommy’s breast.
The first dentition is called a deciduous dentition, popularly known as “milk teeth”, because they have a white color. This phase of the dentition, when complete, has twenty teeth. The teeth eruption begins around six months of life and can go up to two years-old. This process may present some symptoms as: pain, discomfort, heat, increased salivation, fever, itching, vomiting and gastrointestinal disorders. To minimize the symptoms, can be offered to children cold food and drinks, use cooled spoons, gum’s massages and analgesic medication.
However, around six years old, the children start the teeth to change phase. The deciduous dentition is replaced by the permanent one and this exchange occurs gradually until fourteen years old. But, between 18 and 25, it will appear the third molars, the last teeth to erupt in humans. And then, the permanent dentition will be complete and will have 32 teeth.
The permanent dentition will accompany the humans for the rest of their lives. So it is very important to prevent teeth problems and take care of them. (Priscila Langer Teixeira)
