TOOTH  DEVELOPMENT

Healthy baby teeth

     Primary teeth are called baby teeth or first teeth. 

     Your child will start getting new teeth almost continually from age 6 months to age 3 years. 

     Most children have a full set of twenty primary teeth by the time they are three years old.

     As your child nears the age of six, the jaws grows, making room for the permanent teeth.  At the same time, the roots of the baby teeth begin to be absorbed by the tissues around them and the permanent teeth under them begin to erupt.

Front teeth "finally" coming in

     From ages 6 to 12 your child will be losing baby teeth and getting his adult teeth.  These are normal times for tooth eruption however if your child is a year old and still has no sign of any teeth you should contact us for a limited exam.

      Baby teeth are very important as place holders for adult or permanent teeth.  Here are some guidelines that apply to the eruption of baby teeth:

  • Lower teeth usually erupt before upper teeth

  • Girls teeth erupt before boys teeth of the same age
  • Teeth usually erupt in pairs
  • The lower front teeth are the first teeth to be cut

     Permanent teeth usually start to erupt around the first grade.  Often the first molar or six-year molar erupts before the front teeth and they tend to erupt behind the last baby tooth and do not replace a baby tooth.

      Often lower front teeth come in behind, the tongue side, and give the appearance of two rows of teeth for awhile.  The front teeth are changing between the aging of 7-10. 

     By the time your child reaches age twenty-one, all thirty-two of the permanent teeth will usually have erupted.

      Remember around the age of 7  is a good time to visit the orthodontist if you are concerned about the crowding of you child's teeth. 

Tooth Decay Different for Boys and Girls

A new study from Australia suggests that young boys and girls exhibit different tooth decay patterns. While boys have more decay in their baby teeth, the study indicated that girls had more tooth decay as adults.

The study, conducted by the Australian Institute for Health and Welfare (AIHW), also found that boys tend to develop more baby teeth than girls at any age, and girl's permanent teeth arrive earlier than a boy's. The study didn't see any significant differences between the consumption of sugary foods from one gender to the next, which leads them to additionally conclude that cultural factors may account for the noted differences.

"Certainly ... boys, in relation to their oral hygiene, start brushing later in life and brush their teeth less often thangirls,"
researcher Jason Armfield told Australia's Herald Sun paper. Additional findings suggested a strong link between childhood decay and later tooth troubles. The Herald Sun quoted Armfield as noting that "one of the best predictors of having decay in permanentteeth is having decay in baby teeth."
