Correcting the structural dental anomalies caused by CCD is not a matter of standard braces. It requires years of collaborative work between craniofacial specialists, oral surgeons, and orthodontists. Practitioners must cut through dense cortical bone, excise extra tooth buds, attach surgical brackets directly to buried teeth, and slowly pull those teeth down using gold chains.
As documented in a detailed People.com report, Matarazzo took to social media in early 2020 to confirm that his fourth major operation was a "complete success," marking a pivotal transition in his long-term treatment plan.
| Date / Era | Clinical Procedure | Outcome & Significance |
|---|---|---|
| 2015, 2016 | Use of removable prosthetic teeth; initial pediatric oral evaluations | Wore temporary bridges for non-acting functions; starred unadorned in Season 1 |
| 2017 | Third major oral surgery; preliminary extraction of supernumerary teeth | Removed redundant buds crowding his upper jaw; paved the way for orthodontic chains |
| January 2020 | Four-hour surgical intervention; 14 supernumerary teeth removed | Exposed six unerupted adult teeth; bonded brackets to initiate slow traction downward |
| 2021, 2023 | Active orthodontic extrusion and arch stabilization | Adult teeth steadily guided into position; noticeable structural shift during Stranger Things 4 |
| 2024, 2026 | Final cosmetic alignment, occlusal refinement, restorative veneers | Complete reconstruction of functional bite plane for adult theater and screen work |
His January 2020 procedure was arguably the most gruelling phase. Surgeons worked for over four hours to cut away deep gingival tissue and extract 14 extra teeth that were choking his jawbone. Once cleared, they located six adult permanent teeth embedded high within the palate, affixed brackets to their surfaces, and anchored them with surgical sutures so orthodontics could gradually tug them down.
