What if my bite is fine?
Your teeth fitting together is good news, but it doesn't tell the whole story of your face.
Teeth adapt, and can hide what lies underneath
Breathing, eating and communicating are vital needs, and the body always finds a way to meet them. That's why, when the upper jaw (maxilla) and the lower jaw (mandible) lacked growth or development, the teeth compensate: they tilt and shift until they fit together. They may look straight or crooked, but they work. Something similar happens with breathing: if you can't breathe well through your nose, you breathe through your mouth. It's also possible that previous orthodontic treatment left you with a good bite, without addressing the structure of your face and its functions at the time. That compensation, whether natural or achieved with previous treatment, can hide an underlying problem: the base that holds the teeth. A good bite means your teeth found a way to fit together; it doesn't rule out that your face needs a more complete look.
Bimaxillary retrusion: the clearest example
When the upper jaw and the lower jaw both lacked development at the same time, the two developed in proportion to each other, and the bite can fit well. This is called bimaxillary retrusion, and it often goes unnoticed precisely because the bite doesn't draw attention. What shows is somewhere else: in a profile with little projection, in lips and a chin with little support, sometimes in how you rest and, often, in a look of premature aging. In many cases, orthognathic surgery also has a rejuvenating effect, like a reverse facelift: it gives back, from the inside, the support the face was missing. We explain it in detail on the Bimaxillary retrusion page.
Signs worth looking at, even if your bite is fine
- Breathing and rest: breathing through your mouth, snoring, pauses in your breathing during sleep that someone notices, sleep that doesn't leave you rested, or sleepiness during the day.
- Support and profile: lips with little support, a small or poorly defined lower jaw, a neck that doesn't clearly separate from the chin, a nose that looks more prominent than it really is, or a face that looks tired or older before its time.
- Your smile: how your teeth and lips look when you smile, in harmony with the rest of your face.
None of these signs is a diagnosis. They help you suspect that something may be going on, and come to your consultation with clear questions.
How it's evaluated and what options there are
The evaluation looks at your whole face, not just at how your teeth fit together. It starts with a conversation about what you feel, what worries you and your history, and it includes the clinical exam, photographs and 3D scans that show the upper jaw, the lower jaw, the joints and the airway in their real position. If there are signs during sleep, a sleep study is added. With that information, we talk through all the options, with their scope and their limits. When appropriate, the plan includes repositioning the structures of the face in harmony, to give back the space and support they were missing, planned beforehand on a digital twin of your face. The decision is yours, informed and case by case.
Your teeth fitting together is a good starting point. If something about your profile, your smile or your rest leaves you with questions, let's look at your whole face.
Frequently asked questions
Could I need orthognathic surgery if my teeth fit together well?
Possibly, though not always. Breathing, eating and communicating are vital needs, and the teeth adapt to meet them even when the upper and lower jaws lacked development. If there are also signs in your breathing, your rest, your profile or your smile, an evaluation of your whole face is worth it to find out.
Why am I being told about the structure of my face if I've already had orthodontics and my bite is fine?
Because orthodontics can leave you with a good bite without addressing the structure of the face and its functions at that time. This is called compensation, and it's a valid alternative for more limited goals. Looking at the structure doesn't question that treatment: it completes the information about your breathing, your profile and your smile.
What is bimaxillary retrusion?
It's when the upper jaw and the lower jaw both lacked development at the same time. Because the two developed in proportion, the bite can fit well and it can go unnoticed. It shows more in the profile, in the support of the lips and the chin, sometimes in how you rest and, often, in a face that looks older before its time.
Can orthognathic surgery rejuvenate the face?
In many cases, yes. When the face was missing support, as in bimaxillary retrusion, repositioning its structures has a rejuvenating effect, like a reverse facelift: the support is given back from the inside. And because function and beauty go hand in hand, it's planned with your breathing, your bite and your face in mind, all at the same time.
Can snoring be related to the structure of my face if my bite is fine?
Possibly. How the jaws, the muscles and, above all, the tongue, which is anchored to them, grew and are positioned can leave less room to breathe even if your teeth fit together. Snoring can have different causes: sleep apnea is diagnosed with a sleep study (polysomnography) and other tests, and it's handled as a team when the case calls for it.
How do I know if my case involves more than my teeth?
With an evaluation of your whole face: a conversation about what you feel and what worries you, a clinical exam, photographs and 3D scans that show the structure in its real position. With that information, we talk through all the options, with their scope and their limits.
