Cathcart grew up in front of millions of global subscribers. Audiences met her in 2018 when she was just 14 years old, portraying an outspoken middle-schooler with quirky style and expressive facial movements. Her physical transition reflects ordinary adult dental development rather than an artificial Hollywood makeover.
| Production Era | Visual Smile Characteristics | Probable Clinical Status |
|---|---|---|
| To All the Boys (2018, 2021) | Narrow dental arch, mild youthful crowding, prominent negative buccal space. | Untreated adolescent dentition; normal developmental spacing. |
| XO, Kitty Season 1 (2023) | Slight central incisor dominance, persistent minor rotation on upper lateral teeth. | Early adult dentition; natural tooth wear and positioning intact. |
| XO, Kitty Season 2 (2025, 2026) | Expanded arch width, corrected rotations, preserved enamel margins and texture. | Completed clear aligner therapy or targeted adult orthodontic realignment. |
Because Cathcart stepped directly from high school into top-billed roles, completing an orthodontic course between filming schedules fits the standard lifestyle of working young actors. Aligners are removable during shooting days, making them ideal for performers carrying major streaming productions.
