“Dientes chuecos” is the everyday Spanish way of saying crooked teeth. Dentists call it malocclusion, which simply means the teeth and jaws don’t line up the way they should.
Here’s the short answer most people are looking for. Crooked teeth usually come from a mismatch between the size of the jaw and the size of the teeth, an inherited jaw shape, childhood habits such as thumb sucking, or teeth that were lost or came in out of place. They can be corrected at almost any age, most often with braces or clear aligners, followed by a retainer to hold the result. And plenty of mild cases don’t need treatment at all.
The rest of this guide explains what’s behind your smile, which type of misalignment you might have, and how to choose a fix that fits your mouth and your budget.
What Dientes Chuecos Actually Means
People use the phrase loosely. Someone might say it about one front tooth that’s turned slightly sideways, while someone else means a bite where the upper and lower teeth don’t meet at all.
Dentists separate two things:
- Tooth position problems: crowding, gaps or individual teeth that are rotated or tilted.
- Bite problems: how the upper and lower jaws meet when you close your mouth.
This matters because the two are treated differently. A rotated incisor in an otherwise healthy bite is a small job. A bite problem caused by jaw growth may need a longer plan and, in rare adult cases, surgery.
Why Teeth Grow In Crooked
There’s rarely a single cause. According to MedlinePlus, the US National Library of Medicine’s health site, malocclusion is most often inherited, frequently because the jaw and teeth are different sizes. Its page was last reviewed in February 2026.
Jaw and tooth size you inherit
If your teeth are relatively large for your jaw, there isn’t enough room for them to sit in a neat arch, so they overlap or twist. The opposite, small teeth in a large jaw, leaves gaps. Both patterns tend to run in families.
Childhood habits
Habits that keep steady pressure on growing teeth can push them out of line over time. The usual ones are:
- Thumb or finger sucking past the toddler years
- Long-term pacifier or bottle use
- Tongue thrusting, where the tongue presses forward against the front teeth when swallowing
- Mouth breathing, often linked to blocked airways or allergies
Missing, extra or lost teeth
When a baby tooth falls out too early, nearby teeth can drift into the gap and block the adult tooth underneath. Extra teeth, impacted teeth and teeth with an unusual shape can also crowd the arch.
Dental work, injuries and other causes
Poorly fitting crowns, fillings or old orthodontic appliances can change how teeth meet. A jaw fracture that heals out of position, a cleft lip or palate, and, rarely, growths in the mouth or jaw can also affect alignment.
Common Types of Crooked Teeth
Knowing the name of your problem makes a consultation far easier to follow. This table covers the patterns you’ll hear most often.
| Type | What it looks like | Why it matters |
|---|---|---|
| Crowding | Teeth overlap or twist because there isn’t enough space | Harder to clean between teeth, so plaque builds up |
| Spacing | Visible gaps between teeth | Mostly cosmetic, but food can get trapped |
| Rotated or tilted tooth | A single tooth turned or leaning | Often a quick fix if the bite is fine |
| Overjet | Upper front teeth stick out well past the lower ones | Front teeth are more exposed to injury |
| Deep overbite | Upper front teeth cover most of the lower front teeth | Lower teeth can bite into the gums behind the upper teeth |
| Underbite | Lower teeth sit in front of the upper teeth | Can affect chewing and jaw comfort |
| Crossbite | Some upper teeth sit inside the lower teeth | Can cause uneven wear and jaw shifting |
| Open bite | Front teeth don’t touch when the back teeth are closed | Can make biting into food difficult |
Many people have more than one of these at once. Crowding with a mild overbite is a very common combination.
Do Crooked Teeth Always Need Treatment?
No. Minor misalignment often causes no problems, and some people simply like their smile as it is. Treatment becomes worth discussing when the teeth affect how your mouth works, not only how it looks.
Signs that a dental check is a good idea:
- Chewing or biting feels awkward or uncomfortable
- You regularly bite your cheek or tongue
- Floss shreds or catches in the same tight spots
- You notice uneven wear or chips on certain teeth
- Your child breathes through their mouth most of the time or has trouble with certain sounds
Crowded teeth are harder to clean, so plaque and tartar build up more easily in tight spots. That doesn’t mean everyone with crowding gets cavities, but it does mean your cleaning routine has to work harder.
How to Fix Dientes Chuecos: The Main Options
The right option depends on what’s wrong, how severe it is, your age and how much daily effort you can commit to. Here’s what each approach really involves.
Traditional braces
Metal or tooth-coloured ceramic brackets are bonded to the teeth and connected with a wire that the orthodontist adjusts at regular visits. Braces handle almost every type of problem, including complex rotations and bite corrections. They’re fixed in place, so they work even if you’re forgetful.
The trade-offs are cleaning (food catches around brackets) and appearance, although ceramic brackets are much less noticeable than metal.
Clear aligners
These are a series of removable plastic trays, each one shifting the teeth a little further. They’re nearly invisible and come out for meals and brushing, which many adults prefer.
The catch is discipline. Aligners only work while they’re in your mouth, and most treatment plans ask you to wear them for most of the day and night. If you know you’ll leave them in a drawer, braces are the safer choice. Aligners can also be less suited to some complex bite problems, so ask whether your case fits.
Veneers and bonding
Thin porcelain shells (veneers) or tooth-coloured resin (bonding) can make slightly crooked front teeth look straight. This is camouflage, not correction. The teeth don’t move, and veneers usually involve removing some enamel, which can’t be undone. It can suit small cosmetic issues in adults with a healthy bite.
Extractions and jaw surgery
When crowding is severe, an orthodontist may remove one or more teeth to make room. Surgery on the jaw (orthognathic surgery) is reserved for adults whose bite problem comes from the jaw bones themselves, and it’s combined with braces.
Comparing the options
| Option | Best for | How visible | Daily effort | Moves teeth? |
|---|---|---|---|---|
| Metal braces | Almost all cases, including complex bites | Very visible | Careful cleaning | Yes |
| Ceramic braces | Same as metal, more discreet | Less visible | Careful cleaning | Yes |
| Clear aligners | Mild to moderate crowding and spacing, some bite issues | Barely visible | Wearing trays most of the day | Yes |
| Veneers or bonding | Small cosmetic irregularities | Natural look | Normal care | No |
| Surgery plus braces | Severe jaw-based bite problems | Varies | High | Yes |
On timing, MedlinePlus notes that treatment typically runs anywhere from six months to two years or more. Simple cosmetic cases sit at the short end. Bite corrections take longer.
What It Costs
Prices vary a lot between countries, cities and individual clinics, and they change often, so treat any figure you see online as a rough guide only. What drives the cost is consistent everywhere:
- How complex the case is and how long treatment lasts
- The type of appliance (ceramic and aligners often cost more than metal)
- Whether X-rays, scans, extractions and follow-up visits are included
- Retainers after treatment, which are sometimes billed separately
A useful habit: ask every clinic for a written, itemised quote that includes retainers and any replacement aligners. Two quotes that look different are often closer than they seem once you compare what’s actually included.
The Right Age to Get Crooked Teeth Checked
Children
The American Association of Orthodontists recommends a first orthodontic check-up when a problem is first noticed, and no later than age 7. At that age children have a mix of baby and adult teeth, so jaw growth and emerging teeth are easier to assess.
A check-up isn’t the same as starting braces. Most 7-year-olds are simply monitored. A smaller group benefits from early “interceptive” treatment, for example widening a narrow upper jaw or helping a child stop a thumb-sucking habit before it shapes the bite.
Teens
Most full orthodontic treatment happens in the teenage years, once nearly all adult teeth have come in but the jaws are still growing. Growth can make some bite corrections easier.
Adults
It’s not too late. Teeth move at any age as long as the gums and bone around them are healthy. Adults may need a little longer, and the dentist will want to treat any gum disease or decay first.
Why At-Home Teeth Straightening Is Risky
Online kits and unsupervised aligners are tempting because they look cheap and easy. Dental bodies take a firm line here. The American Dental Association adopted a policy in 2017 that strongly discourages do-it-yourself orthodontics.
There’s a practical reason. A 2023 study in Dentistry Journal reviewed reports sent to the US FDA about direct-to-consumer aligners. It found that commonly reported problems included bite problems, pain, sensitivity and gum disease, and that some of these were irreversible.
Moving teeth without an X-ray can push a tooth with hidden decay, weak roots or gum disease in the wrong direction. If cost is the barrier, ask local clinics about payment plans or dental school clinics, where supervised students often treat patients at lower prices.
Keeping Teeth Straight After Treatment
This is the part many people underestimate. Teeth naturally tend to drift back toward their old positions after braces or aligners, which is why almost everyone needs a retainer.
- Fixed retainers are a thin wire bonded behind the front teeth. You can’t forget them, but you have to clean around them carefully.
- Removable retainers are clear trays or wire-and-acrylic plates. They’re easy to clean but only work when worn.
Follow your orthodontist’s schedule exactly. A common mistake is wearing the retainer faithfully for a few months, then stopping once everything looks stable. Shifting often happens slowly, over years, so you won’t notice until it’s already happened.
Caring for Crooked Teeth Day to Day
Whether you’re waiting for treatment or choosing not to have it, a few habits make crowded teeth much easier to keep healthy:
- Use interdental brushes in gaps where floss keeps shredding.
- Try floss threaders or a water flosser for tight, overlapping areas.
- Angle your toothbrush into the spots where teeth overlap, rather than brushing straight across.
- Use a fluoride toothpaste and don’t rinse it away immediately after brushing.
- Keep regular check-ups and cleanings, since tartar builds faster in crowded areas.
Questions Worth Asking at Your Consultation
Going in with questions helps you compare clinics fairly:
- What type of malocclusion do I have, and what happens if I leave it alone?
- Is my case suited to aligners, or would braces work better?
- How long will treatment take, and how often will I need visits?
- Do I need any extractions or gum treatment first?
- What does the quote include, and what does the retainer cost?
- How long will I need to wear a retainer?
The Bottom Line
Dientes chuecos are extremely common, and most cases come down to genetics, jaw size and a few childhood habits rather than anything you did wrong. If your teeth feel fine and you like your smile, you may not need to do anything except clean carefully. If they’re affecting how you bite, chew or clean, or you’d simply like them straighter, start with an exam from a dentist or orthodontist. They can tell you which type you have and which option fits it, and then a good retainer habit keeps the result in place.
Frequently Asked Questions
Can crooked teeth straighten on their own?
Usually not. Some crowding in young children’s baby teeth resolves as the jaw grows, but crooked adult teeth generally stay as they are or slowly get worse without treatment.
Do wisdom teeth make teeth crooked?
The evidence is mixed. Many dentists think wisdom teeth play only a small role, and late crowding is often due to the natural shifting of teeth with age. Your dentist can tell you whether your wisdom teeth need attention for other reasons.
Is it too late to fix crooked teeth as an adult?
No. Healthy teeth can be moved at any age. Adults may need slightly longer treatment and a check for gum health before starting.
How long do I need to wear a retainer?
It depends on your case and your orthodontist’s advice, but many people are told to wear one long term, at least at night, because teeth can shift throughout life.
