Tooth development in children
Your child's primary teeth
usually begin to break through the gums (erupt) at about 6 months of age. For more information, see the topic Teething.
- Teething may be painful. Letting your child chew on a clean, chilled teething ring can help relieve his or her pain.
- Teeth break through the gums in a certain order, generally from the front to the back of the mouth.
- Lower teeth often appear 1 to 2 months before the corresponding upper teeth.
- A change in the order in which the teeth come in may indicate a problem, such as an infection or not enough space for the tooth to grow.
- All of a child's first 20 primary teeth should come in between the ages of 6 months and 3 years.
- Girls' teeth come in a little earlier than do boys'.
Your child's first permanent molars emerge from the gum behind the primary teeth at about age 6, at the same time he or she begins to lose front primary teeth.
- Children lose their 20 primary teeth between the ages of 6 and 11 years.
- Sometimes a permanent tooth will begin to come in before a child loses the primary tooth. This usually is not a problem unless the primary tooth is not loose. In that case, a dentist will need to remove the primary tooth.
- A child's front permanent teeth
- After the permanent teeth have replaced the primary teeth, the child's last molars will come in (four second molars and four wisdom teeth). This takes place between the ages of 12 and 21.
- Sometimes wisdom teeth do not come in properly and need to be removed.
Normally, a person should end up with 32 adult teeth.
