You are on the third page of before-and-after photos. In one, the chin seems to come forward between two pictures, and you are calculating aligners before working out what changed.
Nobody on that results page is distinguishing between the three things they are all calling an overbite.
An overbite in the strict sense is how far the upper front teeth overlap the lower ones vertically, and by itself it does almost nothing to your side profile. What changes a profile is overjet, where the upper teeth sit forward horizontally, or a skeletal Class II jaw relationship, where the lower jaw sits back relative to the upper one.
Overbite, overjet, or a Class II jaw?
An overbite is vertical tooth overlap. Overjet is horizontal tooth projection. A skeletal Class II is a jaw-position pattern. The terms describe different structures and treatment questions, though people often use them as if they were interchangeable.
| What it is | What you see from the side | What moves it |
|---|---|---|
| Overbite: the upper front teeth cover the lower front teeth vertically. | Less lower tooth may show; a deep bite can make the lower face read shorter. | Tooth position, bite correction, and sometimes the surrounding vertical facial pattern. |
| Overjet: the upper front teeth sit ahead of the lower front teeth horizontally. | A more forward upper-lip line and a different chin-to-lip relationship. | Tooth movement, and in some cases the underlying jaw relationship. |
| Skeletal Class II: the lower jaw sits back relative to the upper jaw. | The whole lower third can look set back, not just the teeth or lips. | Growth modification in an adolescent or jaw surgery in an appropriate adult case. |
In everyday speech, people say “overbite” for all three. That drives confusion in searches for an overbite side profile transformation, where a dramatic photograph may show a retruded jaw while the caption talks about teeth.
The reframe is simple: overbite is a tooth word doing a jaw job. Remember it when a photo promises that moving teeth will bring your chin forward.
Caveat: only a dentist or orthodontist examining your bite can tell you which label fits your anatomy.
Which one actually changes your side profile?
Overjet changes the lip line and the relationship between your lips and chin. A skeletal Class II changes the whole lower third. Vertical overbite on its own mostly changes tooth display and perceived lower-face height, so calling every profile concern an overbite sends you toward the wrong explanation.
Yes, a deep bite can shorten the visible lower face. More upper-tooth overlap does not mean the lower jaw moved backward; the effect is mainly vertical and dental.
Think in layers rather than hunting for one guilty feature:
- Teeth: their overlap and projection affect the smile and the lip drape.
- Lips: their resting posture can make a dental issue look more dramatic or less obvious.
- Chin and jaw: their actual position controls the larger lower-third silhouette.
- Camera: angle, distance, and head posture can exaggerate all three.
That is why a man worried about a weak jawline should not assume the answer is bite correction. The jawline may be fine while the lips, chin posture, or camera create the visual effect.
Caveat: a tooth problem and a jaw-position problem can coexist, so a clean distinction does not make diagnosis possible from a selfie.
Where do the dramatic before-and-after profiles come from?
The biggest profile changes usually come from one of three sources: a skeletal case treated with jaw surgery or adolescent growth modification, protrusive front teeth retracted so the lips relax backward, or photographs taken under different conditions. The third source accounts for more internet transformation photos than anybody admits.
The first source is real, but it is not a standard adult aligner story. If the lower jaw is genuinely set back, changing tooth overlap cannot reproduce moving it. Growth modification may suit a growing adolescent; surgery may be discussed for an appropriate adult. Those are clinical decisions, not conclusions to borrow from a collage.
If upper front teeth project forward, moving them can change the lip line as soft tissue drapes over the teeth. The profile may look calmer and the chin-to-lip balance different, even though the mandible has not come forward.
Then there is the camera. A near lens, tilted phone, raised chin, pursed lips, different lighting, or a different smile can create a transformation treatment did not create. As we explain in mirror versus photos, the camera changes the geometry by which you see your face.
The side-profile subculture treats one angle as the truth about a face. Compare a properly taken profile with your real social presence instead of letting one unflattering frame become your identity.
Caveat: good before-and-after photography can document change, but two images alone cannot tell you which structure produced it.
Do people actually look at your teeth?
Dentists look at teeth much harder than the people you meet do. In the eye-tracking study by Zorlu and Camcı, clinicians fixated on modified smile photographs far longer than laypeople did. Among the alterations tested, upper-front-tooth crowding scored lowest at every level of facial attractiveness.
The caveats matter. The base photographs were of three female patients, and the alterations were smile line, gummy smile, crowding, and gaps—not overbite, overjet, underbite, or another bite class. So [ZC2023] cannot prove what an overbite does to a man's side profile. It supports the narrower point that dental professionals inspect mouths more intensely than ordinary observers.
That fits the first-impression evidence from Willis and Todorov. Trait judgements form in about 100 milliseconds, and longer looking mostly increases confidence rather than changing the judgement. The first read is an interpretation of the whole face, expression, posture, and context, not a dental examination.
Crooked or projecting teeth are not invisible. A broad smile can make them more noticeable, and the people-notice-crooked-teeth question deserves a direct answer: sometimes, yes. But “noticed” is not the same as “your side profile is ruined,” or “everyone is auditing your bite.”
Caveat: the study used edited smile photographs, not live conversations, so it cannot measure every real-world reaction.
What can braces or aligners actually move?
Braces and aligners move teeth, plus the soft tissue that drapes over them. In an adult, they do not move the mandible forward. Skilled orthodontics can produce a real profile change through the lips, but that calls for a consultation, not a treatment plan based on a search-result collage.
This is where the phrase overbite is a tooth word doing a jaw job earns its keep. If the visible issue is dental projection, tooth movement may improve the lip line. If the visible issue is a lower jaw that sits back, tooth alignment alone cannot recreate the missing jaw position.
Facial exercise claims have limits too. Reviews found weak evidence, with no control group or randomisation in the reports identified by Van Borsel and colleagues. A separate control-group study could not show facial exercises were effective. A pilot programme in middle-aged women cannot support promises that exercises move an adult male jaw.
Ask a clinician what is being moved, what may change in the lips, and what will not change in the chin. That is more useful than guessing from normal smile versus overbite pictures.
Caveat: orthodontic treatment can be worthwhile for function and appearance, but the right plan depends on your examination, not this article.
What we would actually do first
Separate the image problem from the bite problem before you compare one more transformation photo.
- Take a real profile photo. Use eye level, step back, keep your teeth together, and let your lips rest. Take several frames without pushing your chin forward or back.
- Name the visible layer. Is it tooth projection, lip posture, vertical overlap, or chin position? Compare front and side views. If your chin sticks out only when you smile, read why your chin sticks out when you smile before inventing a jaw diagnosis.
- See a dentist for function first. Mention wear, chewing difficulty, jaw pain, or other symptoms. If appearance is the issue, an orthodontic consultation can explain movement and its limits.
- Check the wider read. The free perceived-appeal test — not a clinical instrument — shows whether one side angle is running your self-assessment.
Caveat: a better photo can correct a distorted question, but it cannot diagnose a bite or replace an examination.
The bottom line
A strict overbite is vertical overlap, and by itself it usually does not reshape your side profile. Overjet can change the lips; a skeletal Class II can change the whole lower third; and photography can manufacture a “before-and-after” gap.
Yes, a deep bite can affect lower-face height, and orthodontics can change a lip line. The useful distinction is whether you want to move a tooth, the soft tissue over it, or the jaw behind it.
Remember the reframe: overbite is a tooth word doing a jaw job. Put the jaw question with an actual clinician, and stop letting one profile photo prosecute your whole face.

Frequently asked questions
Does an overbite affect your side profile?
A true overbite — how far the upper front teeth vertically overlap the lower ones — does little to a profile on its own. What changes a profile is overjet, where the upper front teeth sit forward of the lower ones horizontally, or a skeletal Class II pattern where the whole lower jaw sits back. Most people searching this mean one of the second two.
What is the difference between an overbite and an overjet?
Overbite is vertical overlap; overjet is horizontal protrusion. You can have a deep overbite with almost no overjet and vice versa. The distinction matters because they are corrected differently and only one of them noticeably changes what your face does from the side.
Can braces or Invisalign change my side profile?
They move teeth and the soft tissue draped over them, which can visibly change the lip line and how the chin reads in relation to it. They do not move the mandible in an adult. Skilled orthodontics can produce real profile change through the lips; a jaw that is genuinely set back is a different, surgical conversation with a specialist.
Why do overbite before-and-after photos look so dramatic?
Three sources. Some were skeletal cases treated with surgery or with growth modification in an adolescent. Some are cases where retracting protrusive front teeth let the lips relax back. And a large share are the same face at a different head posture, camera height and lens distance — see what a camera does to your face.
Do people actually notice my overbite?
Dentists do, far more than anyone else. In an eye-tracking study of modified smile photographs, clinicians fixated on the mouth substantially longer than orthodontic patients and laypeople did. First impressions form in around 100 milliseconds and off a frontal view, and people judge whole faces rather than auditing features. Function — wear, chewing, jaw comfort — is the better reason to treat one.
