Many people think orthodontists only treat crooked teeth.
That is part of it, but it is nowhere near the full picture.
An orthodontist deals with problems involving tooth position, spacing, crowding, and the way the upper and lower teeth meet. Some of these issues are mainly cosmetic. Others affect bite function, comfort, cleaning, tooth wear, or long-term stability. In many cases, a patient first notices the appearance problem, while the orthodontist spots the deeper alignment issue behind it.
That is why orthodontic treatment is not simply about making a smile look neater. It is also about correcting the underlying position of the teeth and, where needed, improving the bite itself.
This guide explains the most common problems an orthodontist treats, what those problems actually mean, and when orthodontic treatment may be worth considering.
Quick Answer: An orthodontist treats problems such as crooked teeth, crowding, spacing, overbites, underbites, crossbites, open bites, protruding teeth, and other alignment issues affecting the smile or bite.

Do Orthodontists Treat Crooked Teeth And Crowding?
Yes. This is one of the most common reasons people see an orthodontist.
Crooked teeth may look like a simple cosmetic concern, but they are often linked to crowding or imbalance in the way the teeth fit within the arch. In some cases, one or two teeth sit out of line. In others, several teeth overlap, twist, or sit at awkward angles because there is not enough space.
Orthodontists commonly treat:
- Mild crookedness
- Moderate crowding
- Severe overlap
- Teeth that erupt out of line
- Smiles that look uneven because of alignment
Why Crowding Matters
Crowding is not only about appearance. When teeth overlap heavily, they can be harder to clean properly, which may make plaque control more difficult in certain areas. Crowding can also affect the overall balance of the smile and, in some cases, the bite.
Orthodontic treatment works by creating a more organised tooth position over time, helping the teeth sit more evenly within the arch.
Do Orthodontists Treat Gaps And Spacing Problems?
Yes. Orthodontists also treat spacing issues, where there are visible gaps between teeth.
Some patients dislike gaps mainly because of how they look. Others notice that spacing affects the overall balance of the smile. The reason behind the gaps can vary. Sometimes the teeth are naturally small in relation to the arch. Sometimes the spacing is linked to the bite or the way the teeth have erupted.
Common spacing issues an orthodontist may treat include:
- A gap between the front teeth
- Generalised spacing across the smile
- Uneven spaces between certain teeth
- Spacing linked to bite imbalance
Not Every Gap Needs Cosmetic Treatment
Some patients assume gaps always need bonding or veneers. In many cases, orthodontic treatment may be a better way to close or redistribute spacing because it corrects the position of the teeth rather than covering the issue cosmetically.
If spacing is your main concern, it often makes sense to explore orthodontic treatment in London before considering cosmetic alternatives.
Do Orthodontists Treat Bite Problems?
Yes. Bite problems are a major part of what orthodontists treat.
This is one of the biggest misunderstandings around orthodontics. Many patients think orthodontists only deal with visible straightening, when in reality bite correction is often just as important.
Common bite problems include:
| Bite problem | What it means | Why it matters |
|---|---|---|
| Overbite | Upper teeth overlap the lower teeth too much | May affect function, tooth wear, or smile balance |
| Underbite | Lower teeth sit in front of upper teeth | Can affect bite and appearance |
| Crossbite | Some upper teeth bite inside the lower teeth | May affect chewing and alignment balance |
| Open bite | Some teeth do not meet when biting together | Can affect bite function and closure |
Bite Problems Are Not Always Obvious To Patients
Some people know their bite feels wrong. Others simply think their smile looks off without knowing why. That is where specialist assessment matters. A patient may focus on one crooked front tooth, while the orthodontist identifies an overbite or crossbite affecting the whole treatment plan.
This is one reason specialist orthodontic care can be so valuable in cases that go beyond mild cosmetic straightening.
Do Orthodontists Treat Protruding, Rotated, Or Uneven Teeth?
Yes. Orthodontists regularly treat teeth that stick out, sit at an angle, or are rotated out of position.
These issues may affect one tooth or several. They may also appear alongside crowding, spacing, or bite problems rather than on their own.
Examples include:
- Front teeth that protrude noticeably
- Teeth that are twisted or rotated
- Teeth sitting higher or lower than expected within the smile line
- Teeth that look uneven because of alignment rather than shape
Why Tooth Position Affects More Than Photographs
Patients often notice protruding or rotated teeth because of confidence or appearance. That is understandable. However, these issues can also affect the way teeth meet, how they wear over time, and how balanced the smile looks overall.
Orthodontic treatment aims to bring those teeth into a more controlled and harmonious position rather than masking them cosmetically.
Can An Orthodontist Treat Mild And Complex Problems?
Yes. Orthodontists treat both simple and more complex alignment issues.
Some patients only need treatment for mild crowding or a small gap. Others need correction for multiple issues happening together, such as crowding combined with a deep overbite or protruding teeth combined with spacing elsewhere.
A simple comparison makes this clearer:
| Type of case | Example problem | Possible orthodontic goal |
|---|---|---|
| Mild | Small gap or slight crowding | Improve smile alignment |
| Moderate | Several crowded teeth or visible protrusion | Improve alignment and balance |
| More complex | Crowding plus bite correction | Improve both appearance and function |
That range is why orthodontic treatment cannot really be reduced to just “braces for crooked teeth”. The underlying problem can vary a lot from one patient to another.
Who May Need Orthodontic Treatment For These Problems?
Orthodontic problems can affect children, teenagers, and adults. They are not limited to one age group.
Children may be seen because of developing crowding or bite issues. Teenagers often have treatment while the teeth and jaws are still developing. Adults frequently seek treatment because they want straighter teeth, better bite balance, or a more discreet way to improve the smile later in life.
| Patient group | Common orthodontic problems | Why treatment may be considered |
|---|---|---|
| Children | Early crowding, bite issues, developing alignment problems | Monitor growth and guide timing |
| Teenagers | Crooked teeth, gaps, bite correction | Improve smile and function |
| Adults | Crowding, spacing, protruding teeth, bite imbalance | Discreet straightening and long-term improvement |

Are The Problems Orthodontists Treat Cosmetic Or Functional?
Often, they are both.
A patient may seek treatment because they dislike how their teeth look, but the issue may also affect the bite, spacing, crowding, or the overall balance of the smile. In some cases, the concern is mainly aesthetic. In others, the functional side is just as important.
This is why the same orthodontic problem can be described in different ways:
- “My teeth are crooked”
- “My bite feels wrong”
- “My front teeth stick out”
- “I have gaps I want to close”
- “My teeth overlap and are hard to clean”
Different wording, same specialist area.
If you are still deciding whether the issue is really orthodontic in nature, a consultation with an experienced orthodontist in London is the clearest way to understand what is happening and what your options are.
