Teen · Crowding
The fear of extraction
She sat down in the chair convinced she would lose teeth. She had been told by a well-meaning relative that braces always meant extractions. Twenty-two months later, her crowding was gone and every tooth remained.
Before treatment — in their own words
She was fifteen, and she came to the consultation already anxious. Someone in her extended family had undergone orthodontic treatment years earlier and had four premolars removed in the process. That story had travelled through the family and settled in her mind as orthodontic fact: straightening teeth meant losing teeth. Her mother had brought her anyway, hoping the situation was different. The patient was not convinced.
She sat through the examination with her arms folded. She had decided she would rather live with the crowding.
The clinical picture
The examination told a different story from the one she had imagined. Her crowding was moderate — significant enough to affect her confidence and dental hygiene, but not the kind of severe skeletal case that might once have required premolar extraction. Both arches showed overlapping in the anterior segments. Her bite relationship was broadly Class I with a mild deep overbite. There was enough arch perimeter, with careful management, to resolve the crowding entirely through arch development and interproximal reduction.
Dr. Siju explained this clearly. No teeth needed to come out. She sat forward.
The plan
Treatment proceeded with Invisalign Teen, using gentle arch expansion to create the space the crowded teeth needed to move into position. Interproximal reduction was carried out at the appropriate stages — the slenderising of tooth contacts that creates space without extraction. Attachments were placed to help rotate and torque specific teeth into ideal position. The patient wore her aligners well from the first week; knowing that her teeth were safe appeared to be all the motivation she needed.
Refinement aligners fine-tuned the result in the final months.
The outcome
Twenty-two months after that first apprehensive appointment, the patient completed treatment with a fully aligned smile. Every tooth that was present at the start of treatment was still present at the end. The crowding had been completely resolved. Her bite was correct. Her oral hygiene, which had been difficult to maintain with the overlapping teeth, improved markedly during treatment as access became easier.
She now brings her younger siblings to their consultations. She tells them not to worry about extractions.
