Tooth Shapes and Functions


Teeth are important for the proper digestion we get from food. Teeth have different forms and specific function of chewing. Teeth at the front, called the incisor teeth to chew the food into small pieces. Hand dogs and premolar teeth are sharp and pointed to tearing and cutting products. Molars in the back intended for grinding and rubbing the food into small pieces before swallowing. Humans have two sets of teeth: 20 primary (baby) teeth and 32 permanent (adult) teeth.

Baby teeth

The life of a child's teeth:
  • Milk teeth erupt (do) between 4 and 30 months of age, and, of course, lost between 6 and 12 years.
  • The first teeth to loosen the upper front teeth (Central incisors) at the age of 6 years.
  • The last teeth to loosen are the back teeth in 12 years.
  • Children between 6 and 12 children mixture of infants and permanent teeth (mixed dentition).
Milk teeth are as important as the permanent teeth, because they:
  • Help young children to chew and speak correctly.
  • Take a place in the jaw for the next permanent teeth that are still developing under the gums.
    If a baby tooth extraction (removal) too early, permanent teeth below, can come into curves.
Permanent teeth
  • Kids will have between 28 and 32 permanent teeth.
  • The first permanent teeth to come in front Central incisors at the age of 6 years, with subsequent constant back molars for the baby molars. Be aware of the arrival of the first permanent molar (also called six years molar), because it has many groves and pits, which can make it prone to decay. It is important to regularly clean the back of the mouth and get sealants on the first permanent molars around at the age of 6-7 years. Sealants can help protect new permanent teeth from caries.
  • The second permanent molars come in the age of 12 years, and the need for sealants.
  • Last permanent teeth erupt are third molars (wisdom teeth). Recent data show that wisdom teeth do not need to be removed, except for very specific reasons.
Development of teeth in children is individualized and volcanic just going to change. Some children will receive teeth several years before or after the average age of the guidelines. On the next page is a Tooth eruption Chart showing the child and permanent teeth and age they come in...
