Gaten Matarazzo’s teeth “before and after” show a long medical journey from missing and impacted teeth caused by cleidocranial dysplasia to a much fuller, more typical smile thanks to multiple surgeries, braces, dentures, and likely restorative work. His smile today still looks naturally individual rather than ultra‑cosmetic, but it is far more complete, aligned, and functional than in his early childhood and first Stranger Things seasons.

What was going on “before”?

Early on, Gaten’s teeth were heavily affected by cleidocranial dysplasia (CCD) , a rare genetic condition that disrupts normal tooth and bone development.

  • He had missing front teeth, extra teeth stuck in his gums, and baby teeth that did not fall out on time, which left big gaps and an uneven, childlike smile.
  • As a kid, he often wore removable dentures to fill the front-tooth gaps, taking them out for some scenes in Stranger Things, which is why his character Dustin also appears toothless at times.

Visually, “before” photos show:

  • Gaps in the front, visible missing incisors, and irregular spacing typical of CCD.
  • A softer, more “toothless” grin that became part of his on‑screen identity.

The treatments behind his transformation

Gaten did not just get quick cosmetic veneers; his change was a long medical plan involving surgeries, orthodontics, and prosthetics.

  • He underwent multiple oral surgeries to remove retained baby teeth and “supernumerary” (extra) teeth that were blocking his real adult teeth.
  • In one major operation, around age 17, doctors removed 14 extra teeth and exposed several adult teeth in a single procedure, which he later said was a “complete success” and hopefully his last big surgery.

Key steps in his dental journey included:

  1. Surgical exposure of impacted permanent teeth so they could erupt properly.
  1. Extraction of extra and lingering baby teeth to clear space in the dental arch.
  1. Orthodontic treatment (braces and appliances) to guide teeth into the right positions and align his bite over time.
  1. Use of dentures and other prosthetics to fill gaps while natural teeth were still developing or healing.
  1. Later-stage restorative work such as implants or bridges is considered likely for areas where no natural adult teeth developed, though he has not publicized every detail.

Gaten Matarazzo teeth “after”

Today, Gaten’s “after” smile looks dramatically fuller and more mature but still recognizably his, not the ultra-symmetrical movie-star norm.

  • He now shows a complete set of visible front teeth with far fewer gaps, giving a more typical adult dental arch.
  • His central incisors and surrounding teeth are properly present and aligned, replacing the earlier “missing front teeth” look.

Current photos and recent write‑ups describe:

  • Teeth that are more uniform and whiter, reflecting both natural development and good dental care, rather than obviously artificial veneers.
  • A confident, broader smile that still keeps some unique shapes and minor quirks from his CCD history, which many fans see as part of his charm.

Why his transformation matters

Gaten has used his changing teeth and CCD story to raise awareness instead of hiding it, which is why this “before and after” is more than just cosmetic gossip.

  • He talks openly about his surgeries and condition in interviews and even wove CCD into his Stranger Things character, prompting fans to look up the disorder and donate to related causes.
  • His journey shows how complex medical dentistry, not just cosmetic fixes, can restore function and confidence for people with rare bone and tooth conditions.
