This is the period when the primary or baby teeth begin to fall out and the permanent teeth start to come through.
During this period the jaws grow to make room for the permanent teeth and the roots of the baby teeth begin to be absorbed by the tissue around them.
When a primary tooth is lost early before the permanent tooth beneath that is ready to erupt, the nearby tooth may move into that space. This will later make the permanent tooth to erupt out of its position, creating crooked or crowded teeth.
Key points to remeber during mixed dentition:
- The first permanent molars usually erupt between 6 and 7 years of age and they do not replace any primary teeth.
- This erupts at the space next to the back primary teeth. This permanent molar should not be mistaken for primary teeth.
- When a baby tooth does not fall out when it should, it is good to remove them as this may also make the permanent tooth to erupt out of its position. Your dentist or dental therapist can advise you in this.
- It is also good to remember that the last set of primary teeth is lost only around 12 years of age.
- To avoid future problems with erupting permanent teeth make sure that your child follows effective home care routine and limit the frequency and amount of sugar intake from foods and drinks.
