Crooked Teeth in Children: Early Orthodontic Treatment
Crooked teeth, or malocclusion, are more than a cosmetic concern. They can affect your child's oral health later on. Many parents wonder: "What happens if crooked teeth aren't treated?" When a bite problem isn't treated, it can affect a child in several ways:
Food gets trapped between crowded teeth and is harder to brush away, so the teeth can become more prone to decay.
Children with malocclusion may feel tired jaw muscles, and some have headaches as a result.
Some children also have difficulty with speech.

This article answers the questions parents ask most: what crooked teeth are, how they're treated and what can happen if they're left untreated.
What Are Crooked Teeth?
Crooked teeth (malocclusion) means the teeth don't line up properly in the jaw. This can affect your child's daily life as well as their oral health later on. Crowding usually happens when the jaw hasn't grown enough or there isn't enough room for the teeth to come in.
What Causes Crooked Teeth?
Several factors play a part. Genetics is one of the main ones: if a parent has crooked teeth, their children may too. Inherited jaw shape and a mismatch between tooth size and jaw size can both set the stage for crowding. In fact, genetics plays a large part in how crowding develops.
Genes aren't the whole story. Habits and environment matter too. Thumb sucking, long-term pacifier use and problems with jaw growth can all stop teeth from coming in straight. The AAPD links long-term sucking habits with open bite and crossbite.
Pacifier use after age 3: The AAPD suggests helping children stop pacifier and thumb-sucking habits by about 36 months, because the changes they cause can persist after the habit stops. |
In an ideal bite, the upper teeth sit slightly over the lower teeth and the upper back teeth fit into the grooves of the lower back teeth. When teeth don't line up like this, it's called malocclusion. It means the teeth and jaws are out of alignment, and it's best spotted and treated early.
Two of the most common types in children are overbite (the upper teeth stick out too far over the lower teeth) and underbite (the lower teeth sit in front of the upper teeth).
Overbite: the upper front teeth stick out too far or cover the lower front teeth too much.
Underbite: the lower front teeth sit in front of the upper front teeth.
Open bite: the upper and lower front teeth don't meet when the child bites down, leaving a vertical gap at the front.
Problems during development can also cause crooked teeth. If baby teeth are lost too early, or don't fall out at all, the permanent teeth may not come in straight. Because early loss of baby teeth raises the risk of bite problems, keeping that space open matters. Space maintainers are used after early tooth loss to hold the space so the permanent teeth can come in in the right position.
Signs of Crooked Teeth
The main signs are overlapping, irregular or clearly twisted teeth. You may also notice your child struggling to chew, drooling, or saying their teeth don't fit together properly when they bite.
Speech problems such as a whistling sound or a lisp can also be an early sign.
Treating Crooked Teeth
How crooked teeth are corrected depends on your child's age, jaw structure and how severe the problem is.
Treatment Options Compared
Treatment | Typical age | Typical duration | Visibility | Used for |
Clear aligners | 12+ | 6–18 months | Almost invisible | Mild to moderate crowding |
Palatal expander | 7–12 | 3–9 months | Not very noticeable | Narrow upper jaw, crossbite |
Functional appliances | 6–10 | 6–18 months | Noticeable | Jaw growth problems |
Space maintainers | 3–12 | Until the permanent tooth comes in | Not very noticeable | Early loss of baby teeth |
Metal braces | 10+ | 12–36 months | Noticeable | Moderate to severe crowding |
Ceramic braces | 12+ | 12–36 months | Less noticeable | Moderate crowding |
Preventive orthodontic treatment, started in childhood, can stop crooked teeth from getting worse. It can involve a palatal expander or a space maintainer. Appliances that help children break habits such as thumb sucking can also be part of treatment. Treating early can reduce the need for more extensive treatment later.
Clear aligner treatment is a widely used, modern way to straighten teeth. Aligners are discreet and practical, fit into daily life, and can be taken out and cleaned easily, which is why many children and adults choose them.
Braces are another option. Small brackets are attached to the teeth and gradually move them into line, and clear or tooth-coloured brackets are less noticeable.
Fixed metal braces are held on the teeth with brackets, bands and flexible wires. They're sturdy and move teeth steadily into position.
Ceramic braces use clear or tooth-coloured brackets and wires, so they're less noticeable than metal braces.
Lingual braces are attached to the inside surfaces of the teeth, next to the tongue. They work like conventional braces but can't be seen from the front.
The right way to correct crooked teeth comes down to an individual assessment and a treatment plan made for your child.
Why Early Diagnosis Matters
Timing matters. Between ages 7 and 9 the jaw is growing actively, which is why early treatment often works well in this period. That's why regular dental check-ups for children are so important. So what can happen if crooked teeth aren't treated early?
Physical problems:
- Jaw joint problems
- Uneven tooth wear
- Higher risk of gum disease
- Chewing difficulties and digestive problems
Psychological and social effects:
Some children feel self-conscious about crooked teeth, and this can affect how confident they feel with other children.
Long-term effects:
If treatment starts after puberty:
- it can take longer,
- and some options that work during growth, such as jaw expansion, may no longer be possible.
Orthodontic Options by Age
Age | Type of treatment | What can be done | Suggested check-ups |
3–6 | Preventive | Breaking habits, early diagnosis | Every 6 months |
7–9 | Early intervention | Palatal expansion, space maintainers, functional appliances | Every 3 months |
10–12 | Mixed dentition | Palatal expansion, metal/ceramic braces | Regular check-ups |
13–18 | Permanent dentition | Clear aligners, braces | Regular check-ups |

Frequently Asked Questions
1. My child's teeth look crooked. What should we do?
Start with a dental check-up. The dentist looks at how your child's teeth and jaws are developing and whether treatment is needed now or can wait. Depending on age and the type of problem, options range from habit-breaking appliances and palatal expanders to nearly invisible clear aligners for mild crowding in older children. Clear aligner treatment is comfortable for most children and fits easily into school and daily life.
2. Can crooked teeth be fixed without braces?
Often, yes. Clear aligners, functional appliances, and preventive treatments such as palatal expanders and space maintainers can treat crooked teeth without braces.
Clear aligners are custom-made trays that are changed every two weeks or so, gradually moving the teeth into line. Because they're nearly invisible, many children find them easy to wear at school.
If the crowding comes from the way the jaw is growing, functional appliances can help. They guide jaw growth in children who are still growing and help the teeth come in in the right position, for example when a thumb-sucking habit has affected the jaw.
Palatal expanders and space maintainers can help prevent bigger problems later. If baby teeth fall out too early, for example, a space maintainer keeps room for the permanent teeth.
3. How long does it take to straighten crooked teeth?
Depending on how crooked the teeth are, the treatment chosen and how well your child follows it, treatment usually takes anywhere from 6 months to 3 years. As we said above: early orthodontic treatment can shorten the process.
4. Can crooked teeth affect speech?
Yes. When teeth don't line up properly, some sounds are harder to make, which can lead to speech problems. This is more likely when the misalignment is severe, for example when the upper and lower teeth don't meet as they should.
5. Can teeth become crooked again after treatment?
Wearing a retainer after treatment helps keep the teeth in their new position.
6. How much does treatment for crooked teeth cost?
The cost depends on the treatment chosen and how long it takes. For details, visit our clinic or give us a call.
