Why doesn't Dustin have teeth in season 3

One of the most shocking character changes in Stranger Things season 3 was Dustin Henderson’s sudden lack of teeth. His wide, gap-toothed grin led many fans to ask: what happened to Dustin’s teeth? Let’s analyze some possible explanations for this surprising development.

A Recap of Dustin’s Smile

First, a recap of the progression of Dustin’s smile over the previous seasons:

  • In season 1, Dustin sports a mouthful of shiny white teeth. His big grin is an endearing part of his goofy charm.
  • In season 2, Dustin is missing a couple of teeth here and there. This seems natural, as he’s likely started losing some baby teeth. But overall, he still has most of his teeth.
  • When season 3 premieres, Dustin’s teeth are almost all gone. He reveals a pronounced gap when he smiles due to having lost the majority of his bottom teeth. Only a few top teeth remain.

This sudden change between seasons 2 and 3 surprised many fans. What could have caused Dustin’s teeth to disappear so abruptly?

Explanation 1: Dustin is Growing Up

The most plausible explanation is simply that Dustin is growing up.

Losing baby teeth and getting adult teeth is a natural rite of passage in childhood development. The timing varies for each child, but generally peaks around ages 9-12.

Here are the characters’ ages over the course of the show:

  • In season 1, the kids are 12 years old.
  • In season 2, they are 13.
  • In season 3, they have just turned 14.

So it makes sense that Dustin would rapidly lose the last of his baby teeth right around season 3 at age 14. This fits with the normal timeline of teeth replacement in adolescents.

Dustin’s sudden lack of teeth demonstrates his transition into young adulthood. Like the show itself, little Dustin Henderson is all grown up!

How Teeth Replacement Typically Progresses

To better understand Dustin’s specific dental timeline, let’s look at how teeth replacement typically progresses:

  • Early signs: Around age 6-7, children’s teeth may start becoming loosely rooted as the adult teeth develop underneath.
  • First teeth lost: Most kids lose their first teeth around age 6-8. These are often the front bottom teeth.
  • Peak tooth loss years: Ages 9-12 are when kids tend to lose the most teeth. They may lose up to 3-4 teeth in a month during this time.
  • Last teeth lost: By age 12-14, kids begin losing their final baby teeth as the adult teeth take over.
  • Adult teeth fully in: Most or all adult teeth are fully grown in between ages 17-21.

Based on this, it makes sense that Dustin would have lost the bulk of his remaining baby teeth between seasons 2 and 3 at ages 13-14. This is the prime time for losing those last stray baby teeth.

Close Inspection of Dustin’s Smile

A closer look at Dustin’s grin in season 3 shows:

  • He is missing all of his bottom teeth except possibly 1-2 back teeth.
  • On top, he has his prominent front two teeth, as well as a couple of smaller teeth towards the back.

So while he may only have around 4-6 teeth total, they are positioned in a way that makes the gap look more extreme.

Do Boys Lose Teeth Later?

Do Boys Lose Teeth Later?

An interesting facet is that girls often lose their baby teeth earlier than boys. The timeline can be up to 6 months to 1 year later in boys.

So the fact that Dustin lost his teeth a bit later than his female friend Eleven is also consistent with normal biological development patterns.

This further confirms that Dustin’s teeth disappearance stemming from adolescent growth and delayed male timeline makes sense.

How Other Kids Handle Missing Teeth

Losing baby teeth is traumatic for some kids, but others take it in stride. Dustin seems unfazed by his tooth loss, showcasing his goofy new grin with confidence.

Some kids have difficulty speaking or eating with missing teeth. But clever Dustin adapts quickly, devising creative ways to eat even sticky foods like pizza.

Dustin’s gap-toothed smile even becomes a “trademark” look that his friends rib him about affectionately. This matches how many close-knit groups of friends gently tease each other during puberty.

Explanation 2: The Upside Down?

Could Dustin’s dental issues instead be linked to the sinister parallel dimension known as the Upside Down?

Exposure to the Upside Down has posed health hazards before, most notably Will’s “now-memories” and visions of the alternate reality. Perhaps it also has long-term effects on teeth?

Dustin did have direct contact with the Upside Down through the gate at Hawkins Lab in season 1. He also took care of Dart, who originated from the Upside Down, in season 2.

However, his friends like Will and Mike had equal or greater Upside Down exposure without suffering tooth decay. So while an interesting theory, this seems unlikely.

Explanation 3: Poor Dental Care?

What about poor dental hygiene? Could Dustin simply be neglecting proper brushing and dental visits?

This doesn’t hold up under scrutiny. Dustin shows no other signs of tooth problems – no discoloration or cavities are visible on his remaining teeth.

His friends also eat similar junk food diets without tooth issues. Unless Dustin has a secret candy addiction, tooth decay due to poor care is doubtful!

The Duffer Brothers Weigh In

Ultimately, the Duffer Brothers confirmed that Dustin’s tooth loss resulted naturally from adolescent development:

“Like most young teens, Dustin is losing his baby teeth. This sometimes happens in awkward patterns which can be embarrassing at that age.”

The show creators verify what made the most sense all along – Dustin’s gap-toothed grin is just a rite of passage for many kids his age.

Fan Reactions: Love It or Hate It?

Fans had lots of opinions on Dustin’s sudden lack of teeth when season 3 premiered. Some loved his goofy new look:

  • “Dustin’s smile is so endearing now!”
  • “Those sweet gapped teeth are everything.”

Not everyone was a fan, though:

  • “I can’t get over how distracting Dustin’s teeth are now. Or lack thereof.”
  • “It just looks so unrealistic for a kid that age to have so few teeth. Takes me out of the story.”

Regardless of aesthetics, most fans understood the maturity behind Dustin’s dental change, even if they disliked the look itself.

Will Dustin get his teeth back eventually?

If following the typical dental development timeline, Dustin should have most or all of his permanent adult teeth grown in by ages 17-21.

So in future seasons set a few years later, we can expect Dustin’s adult teeth to fill out his smile again. But the show may continue finding creative ways to depict Dustin’s awkward tween years:

  • In season 4 set 1-2 years after season 3, Dustin may still have gaps as his adult teeth come in.
  • By the time Dustin is 16+ in potential later seasons, he’ll likely have his familiar full grin back again.

Regardless of how his smile matures, toothless or toothy, Dustin Henderson remains the same lovable, wisecracking teen we know and love.

Why Dustin’s Teeth Represent Growing Pains

In the end, Dustin’s dental issues symbolize growing pains – both literally and figuratively.

On the surface, his tooth loss represents the physical maturation process. His gappy grin shows that Dustin is no longer a cute little kid – he’s becoming a young man right before the audience’s eyes.

But it also demonstrates the emotional growing pains of adolescence. We see Dustin struggle with feelings of rejection and wanting to fit in and impress girls.

Dustin’s missing teeth may draw unwanted attention, but they show he can ultimately rise above superficial shortcomings with confidence and humor.

For viewers, Dustin’s jarring toothlessness represents the loss of innocence and letting go of childhood. Both the character and show are maturing into new phases. It reminds us that change is inevitable, but can also bring newfound strength.
