What does a normal bite look like?
In a normal bite, the upper front teeth sit slightly in front of the lower ones and overlap them by a small amount, often covering roughly a quarter to a third of the lower front teeth. The back teeth meet evenly on both sides, with the upper back teeth sitting slightly outside the lower ones, and the centre lines roughly match. Small variations are common; the specialist orthodontists at Creative Arts in Dubai can check yours.

What is a normal bite, in plain terms?
"Bite" (or occlusion) simply means the way your upper and lower teeth meet when you close your mouth. Orthodontists describe a healthy bite with a handful of features:
- Overbite (vertical overlap): the upper front teeth cover part of the lower front teeth when you bite together. A small overlap is normal and protective.
- Overjet (horizontal distance): the upper front teeth sit just in front of the lower ones, typically a couple of millimetres, close enough that they nearly touch.
- Back teeth: the upper back teeth sit slightly outside the lower ones all the way round, and the teeth on both sides meet at the same time.
- Midlines: the gap between the two upper front teeth roughly lines up with the gap between the two lower front teeth and with the middle of the face.
- Arch shape: each row of teeth forms a smooth curve without major crowding or gaps.
Orthodontists call a bite where the jaws are in a balanced front-to-back relationship Class I. Many Class I bites still have crowding or spacing; the class describes how the jaws and back teeth relate, not whether the teeth are straight. The guide to types of bite explains Class II and Class III and every named bite problem in detail.
What does a normal bite look like from the side?
The side view is where most people get confused, because you cannot easily see your own teeth in profile. Two things orthodontists look for:
- The canines interlock. When you bite on your back teeth, the pointed upper canine (eye tooth) fits into the gap between the lower canine and the first lower premolar behind it, like a key in a lock.
- The front teeth form a gentle step. From the side, the upper incisors sit just ahead of and slightly over the lower incisors, with their edges angled slightly forward rather than tipped far out or tilted back.
From the outside, the lips usually close without strain at rest and the lower jaw sits neither noticeably back nor forward. Face shape varies enormously and is not a reliable test on its own; if you are curious about what orthodontic treatment can and cannot change in a profile, see do braces change your face shape.
Normal bite vs overbite, underbite and other common bites
What you might notice in a mirror, and how each bite compares with a typical healthy one. A mirror can raise a question; only an examination answers it.
| Bite | What you may see when biting together | Compared with normal | More information |
|---|---|---|---|
| Normal bite | Upper front teeth slightly in front of and over the lower ones; back teeth meeting evenly | Reference point; small variations are common | This guide |
| Deep overbite | Lower front teeth mostly or completely hidden; sometimes they touch the gum behind the upper teeth | Too much vertical overlap | Overbite correction |
| Large overjet (protruding teeth) | Upper front teeth stick out well ahead of the lower ones | Too much horizontal distance | Overbite correction |
| Edge-to-edge bite | Front teeth meet tip to tip | No overlap and no overjet | Edge-to-edge bite |
| Underbite | Lower front teeth sit in front of the upper ones | Reversed overjet | Underbite correction |
| Crossbite | Some upper teeth bite inside the lower ones, at the front or side | Upper teeth should sit outside | Crossbite correction |
| Open bite | A gap between upper and lower front teeth even with back teeth closed | No vertical overlap | Open bite correction |
Several of these can occur together, and the same appearance can come from tooth position or from jaw size. That is why X-rays and measurements are part of an orthodontic assessment.
How much overbite is normal?
Some overbite is normal and healthy: it guides the jaw when you bite and protects the front teeth. In a typical bite the upper front teeth cover roughly the top quarter to third of the lower front teeth. Orthodontists usually describe a bite as a deep bite when the overlap is much larger than that, for example when the lower front teeth are almost completely hidden or bite into the gum behind the upper teeth. A deep bite can wear the front teeth, irritate the gum and limit the space for crowns or veneers in future.
"Overbite" is also used loosely for teeth that stick out. Strictly, that is overjet, the horizontal distance. A large overjet makes the upper teeth more likely to be injured in a fall and can make the lips harder to close. Both are measured at an assessment rather than guessed by eye.
Is an edge-to-edge bite normal, and how does an underbite differ?
An edge-to-edge (end-to-end) bite, where the upper and lower front teeth meet tip to tip, is not a typical bite, although it is common and does not always need treatment. Without the usual overlap, the edges can chip and wear over time, and sometimes the jaw slides forward to reach that position. The edge-to-edge bite guide explains when it is worth correcting.
An underbite goes one step further: the lower front teeth sit in front of the upper ones. The difference between an underbite and a normal bite is therefore the direction of the overlap. Some underbites are caused by tooth position and respond to braces or aligners; others reflect a larger lower jaw or smaller upper jaw and may need growth guidance in children or, in adults, combined orthodontic and surgical treatment.
How to check your bite in a mirror
A quick self-check you can do at home in good light. It cannot replace an examination, but it helps you describe what you see.
| Step | What to do | What usually looks normal |
|---|---|---|
| 1. Relax | Sit upright, let your jaw relax, then close gently on your back teeth without forcing them together | Teeth meet without you having to slide the jaw |
| 2. Look from the front | Pull your lips back with clean fingers and look at the front teeth | Upper front teeth cover a small part of the lower ones; centre lines roughly match |
| 3. Look at the sides | Pull one cheek back at a time and look at the back teeth | Upper back teeth sit slightly outside the lower ones on both sides |
| 4. Take a side photo | Ask someone to photograph your bite from the side with cheeks held back | Upper canine fits between the lower canine and the tooth behind it |
| 5. Bite and slide | Close, then slide your jaw forward and to each side | Movement feels smooth; no single tooth knocks first or hurts |
| 6. Look for wear | Check the edges of the front teeth | Edges look even, without flat shiny areas, chips or see-through tips |

Orthodontics at Creative ArtsWhen should a bite be checked by an orthodontist?
A bite does not need to be textbook-perfect, and many people with small variations never need treatment. It is worth an orthodontic check if you notice any of the following:
- Front teeth that meet edge to edge, or lower teeth in front of the upper ones.
- Lower front teeth that are completely hidden, or that bite into the gum behind the upper teeth.
- A gap between the front teeth when the back teeth are closed.
- Chipping, flattening or see-through edges on the front teeth.
- The jaw shifting to one side as you close, or centre lines that are far apart.
- Jaw pain, clicking or difficulty chewing; a TMJ assessment looks at the joints as well as the teeth.
- Teeth that have started to move or crowd in adulthood; see why teeth shift in adults.
For children, the American Association of Orthodontists recommends a first orthodontic check no later than age 7, when a mix of baby and adult teeth lets developing bite problems be spotted early.
At Creative Arts, bites are assessed by our specialist orthodontists, Dr. Muhannad Kazzaz and Dr. Valeriia Kozachenko. The visit includes an examination of the teeth, bite and jaw movement, an intraoral 3D scan and X-rays where needed, and an explanation of whether anything needs treatment, followed by a written plan if it does.
