Hello
The permanent maxillary 1st premolar erupts at approx 9-10 years of age, followed by the canine at around 10-11 years and then the second premolar at approx 11-12 years of age. This sequence of eruption is important for the formation of a proper occlusion in the oral cavity. Given that your child’s age is 9 years presently, we ll have to wait for the eruption of the permanent teeth in this case. Any kind of space closure can be carried out only one the permanent teeth have erupted, i.e. at approximately 12 years of age.
Next Steps
Hence it is advisable to wait and watch presently and maintain the child’s oral hygiene by making him brush twice daily, rinsing his oral cavity after every meal for the removal of any food debris and ensuring that he does not have any oral habits like mouth breathing, tongue thrusting, lip biting, etc.
