Milly Alcock's Dental Transformation: A Professional Overview
Milly Alcock's smile changed between seasons one and two of House of the Dragon. You could catch it in close-ups during the S2 premiere press tour. The difference is subtle, but it's there - and it's sparked the kind of conversation that usually follows young actors in the public eye.
The main thing people noticed? A visible gap between her upper front teeth that was clearly present in season one but appears narrower - some say nearly closed - by season two. Side-by-side comparisons on TikTok and Reddit pulled this apart frame by frame. Was it camera angle? Makeup? Or something more permanent?
Looking at it from a cosmetic dentistry angle, this looks like composite bonding. Straightforward procedure: a tooth-colored resin gets layered onto the enamel, shaped, then hardened with a curing light. Each tooth takes about 45 to 70 minutes. Depending on the provider and location, cost in the US falls between $300 and $600 per tooth.
That's a guess, mind you. I don't have Alcock's dental records. Here's what fits with what we see: the gap reduction is symmetrical. Both central incisors ended up with pretty much the same width. That suggests bonding, or maybe a single thin porcelain veneer on one tooth, rather than braces, which wouldn't move that fast unless they were already in use and just happened to close a gap between seasons.
Bonding is reversible. Veneers aren't reversible, once the enamel is shaved down, you're committed. For a young actor whose face is her instrument, reversible probably sounds better. You can always undo it later.
Another option is Invisalign or similar clear aligners, used to close a minor gap over 12 to 18 months. But that timeline doesn't line up with the two-year break between seasons. Alcock was 22 when season one aired and 24 during press for season two. Two years is plenty of time for aligners. Yet the change we see is localised to those two teeth, not the alignment of her full arch. That makes dental bonding the simpler explanation. It's worth reading up on teeth straightening surgery before you commit.
The actor herself hasn't commented publicly on any dental work. Most celebrities don't. Dental transformations in Hollywood are treated like wardrobe changes, part of the craft, not the conversation.
Did Milly Alcock Get Her Teeth Fixed?
If you've caught Milly Alcock on screen, chances are you've wondered whether her teeth had some help from a dentist. She's best known for playing young Rhaenyra Targaryen in House of the Dragon, and her smile now looks noticeably different from earlier photos from her career in Australia. Side-by-side shots from 2021 and 2023 show a shift, her teeth appear whiter, more aligned, the edges slightly more even. There's more detail in our guide to Sierra Ferrell's veneers.
She hasn't confirmed any work publicly, and that's pretty standard. Most celebrities, like Milly, don't detail every tweak.
Composite bonding - A tooth-colored resin is sculpted onto the tooth surface. It can fix chips, close gaps, and reshape edges. Cost runs roughly $250 to $600 per tooth in the US. Lasts about 3-5 years before needing a touch-up.
Porcelain veneers - Thin shells bonded to the front of teeth. They correct alignment issues and whiten permanently, and price tag is steeper: $1,000-$2,500 per tooth. With proper care, they can last 10-15 years.
Looking at her smile now, I'd bet on bonding.
You get a natural look-not that unnaturally bright "Hollywood white" you see with some veneers. The edges have a slight translucency that mimics real enamel, and bonding allows for a subtler change.
And so there's the timeline, and she filmed House of the Dragon through most of 2021. By the time promos dropped in 2022, fans noticed a difference. That's fast enough for bonding-one or two appointments-rather than full veneers, which often require multiple visits and temporary teeth.
Late 2022 interview clips show a slight length difference between her front teeth, a natural quirk veneers rarely leave behind.

Understanding the Changes: Veneers, Orthodontics, or Both?
Line up Milly Alcock's early headshots next to her House of the Dragon press-tour photos, and the difference hits you right away. Whiter, yes, but also more uniform in shape and length. Whitening strips alone don't get you that kind of change. So what actually happened? The three usual suspects: veneers, orthodontics, and bonding.
Veneers are the heavy hitter in Hollywood smiles. A thin porcelain shell, custom-made and bonded to the tooth's front, can fix color, size, and minor alignment in a single go. Each tooth runs $1,000 to $2,500. Alcock's teeth show the classic signs. Edges are smooth and even. Color's consistent across every visible tooth. And the incisors are slightly longer than before. That's a veneer signature. You can lift the gumline subtly too, but in her case the length changed just enough.
Orthodontics takes longer. Braces or clear aligners like Invisalign need months of wear. You'd see attachment bumps in candids. Did we catch her with attachments in any selfie? Not that I can find. Her bite looked fine before, so a full ortho round isn't likely. Possibly she did a short elaboration, six weeks of aligners to close a minor gap or tweak a rotation. That would show up as temporary blips on the tooth surface. I don't see those in the paparazzi shots.
Then there's composite bonding, and this is cheaper ($300-$600 per tooth)and reversible. A dentist layers resin on the enamel and sculpts it, then cures it with a light. It can change tooth shape and hide chips. It can even out edges. For an actress who might not want permanent changes at 24, bonding is a smart play. But bonding wears down faster and stains more easily, it's the trade-off. If her smile stays pristine over two years (that's porcelain)not resin.
I'd bet on veneers, probably the top six or eight, and cost fits her rising profile. The result is dramatic but still natural. And maintenance is lower than bonding. Did she also whiten? Sure, but that's pretty much a given. So the real question is whether she went all-in or just did a few front teeth.
Without X‑rays or a statement from her dentist, everything about Milly Alcock teeth is just educated guesswork. But smile analysis like this isn't new-it's how dentists spot what their colleagues created.
Addressing the Question of Buck Teeth and Other Conditions
Here's the thing about Milly Alcock's smile - people either love it or they can't stop analyzing it. The question comes up constantly in reddit threads and celeb commentary: does she have buck teeth? Is that an overbite? Something else going on?
Let me clear this up. Milly Alcock doesn't have buck teeth in the clinical sense. What you're seeing is a slight protrusion of her upper front teeth, combined with a naturally fuller lip shape. It's subtle. This are called by A dental professional a mild Class I malocclusion at worst. Meaning the bite itself is fine, but the front teeth angle forward just a bit more than what we'd call 'ideal'. We go deeper on this in our guide to treatment options for buck teeth.
Buck teeth technically means the upper front teeth stick out noticeably past the lower ones, usually more than 2-3 millimeters of overjet. Alcock's gap is smaller than that. Her smile looks distinctive, not misaligned.
That slight forward tilt gives the smile a natural, un-engineered look. In Alcock's case, it works, and she never hid it, never 'fixed' it. And honestly? That's part of why House of the Dragon casting directors credibly picked her. Her look is straight out of medieval times, not a veneer commercial.
Other things people speculate about:
Diastema (gap between teeth)she doesn't have a noticeable one. Zero evidence for this one.
Gummy smile, No. When she smiles (the gum exposure is within a normal)healthy range.
Overbite vs. overjet: Overbite (vertical overlap) appears normal, and overjet (horizontal protrusion) is slightly above average. That's what you're noticing, most likely.
Bottom line: Milly Alcock's teeth aren't buck teeth. They're just hers - unmodified and a bit forward, which makes them memorable.
Why Does Milly Alcock Look So Different? Facial Analysis
Milly Alcock's face reads differently from role to role - fans noticed that when she popped up in Supergirl versus House of the Dragon. The shift isn't just due to makeup or weight. It's structural. Her teeth are the biggest clue.
When she's relaxed, Alcock has what orthodontists call a gummy smile. Her upper lip rides high, exposing a long band of gum above her incisors. That alone shifts the lower-third proportion of her face. In some shots her central incisors appear long, in others short. That's the lip line playing tricks, and the teeth themselves are slightly flared ( proclined ). This tilts her profile forward, lending her jawline a stronger, almost assertive look when her mouth is closed. But when she smiles, the flare softens. She looks younger now. The contrast is stark.
Three factors create the 'different' look:
Lip-to-tooth ratio. At rest, Alcock shows about 4-5 mm of gum and the full height of her incisors. That's on the higher end. Most people show 2-3 mm. This extra gum draws the eye downward, making the midface feel longer.
Nasolabial fold depth. Because her upper lip lifts high and her maxilla (upper jaw) is a touch forward, the crease from nose to mouth blocks a lot of light. Front-on lighting brings it out. In side lighting, it disappears. The look toggles between soft and sharp depending on the scene.
Cheekbone width vs. jaw width, and her zygomas are broad, her mandible narrow. That V-shape reads angular in profile but delicate in three-quarter view. The teeth sit inside that narrow arch. Any widening of the smile (a full-teeth grin)for instance, makes the face look wider suddenly.
The upper jaw is slightly ahead of the lower (but the bite compensates)teeth meet correctly, yet the skeleton reads differently than a typical face. Alcock's milly alcock teeth aren't a flaw, and they're the detail that makes her face unpredictable across angles.
One more thing: her vermillion lower lip is full and everts, curls outward. That pulls the chin down visually, making it look shorter.
