The aim of early treatment is to address any underlying jaw problems. It does make future orthodontic treatment with braces simpler. It is important to note that while braces move teeth, it does not correct the underlying jaw structure. Often through correcting the jaw structure, it allows us to position the teeth into their correct positions, creating the ideal smile.
In late teens and adults, correcting this same jaw structure when the bones have hardened could mean jaw surgery may be required, with additional costs, time and complexity of treatment.
In other words, early orthodontic treatment does not prevent braces, but it allows your child to attain ideal smile outcomes.
Treatment can be something simple, like wearing a plate or having an expander, which all help to prevent the crowding from worsening as more adult teeth develop.
