Crooked and misaligned teeth develop from a mix of genetic and environmental factors. The most common cause is a jaw that doesn't have enough space to fit all the teeth as they come through, causing overlap or crowding. Jaw size and the tendency toward crowding or spacing often run in families. Environmental factors can include prolonged thumb sucking, early loss of baby teeth, mouth breathing, and tongue-thrusting habits. In adults, teeth can also shift gradually due to gum disease, tooth loss, or normal age-related changes.

Not only. Overlapping or crowded teeth are harder to clean effectively, a toothbrush can't reach every surface and floss is difficult to manoeuvre between tightly packed teeth, which lets plaque build up undisturbed and raises the risk of decay and gum disease. An uneven bite can also place extra force on certain teeth, which over time can contribute to wear, fractures, and jaw discomfort.

Malocclusion is the clinical term for misalignment of the teeth and jaws. It covers crowding, spacing, overbite, underbite, crossbite, and open bite. Each type has different causes and treatment approaches, which is why a thorough examination is the starting point.

For children, early assessment can be valuable, the Australian Dental Association recommends an orthodontic evaluation by around age seven, since some issues are easier to address while the jaw is still growing. That said, orthodontic and cosmetic alignment options aren't limited to children, adults of any age can look into treatment. The most appropriate timing and approach depends on the type of misalignment, your age, and your goals.

Veneers can improve the appearance of mildly crooked, gapped, or uneven teeth without orthodontic treatment, which is why some adults choose them for a faster cosmetic result. It's worth understanding that veneers change how the teeth look, not their actual position. For crowding, spacing, or bite issues, orthodontic treatment that physically moves the teeth is generally the more appropriate option.

Misalignment can gradually affect both oral health and function if left untreated. Crowded teeth are harder to clean, which can raise the long-term risk of decay and gum disease. Uneven biting forces can accelerate wear on certain teeth, potentially leading to fractures or sensitivity over time. In adults, teeth continue to shift gradually, so mild misalignment can become more noticeable if it's not addressed.

Yes. Treatment is available for adults of any age. It can sometimes take a little longer than in children or teenagers, since the jaw is no longer growing, but it remains a realistic option. Adults also have the choice of cosmetic approaches like veneers for mild misalignment, or Invisalign for a more discreet orthodontic option.

In some cases, yes. The position of the teeth plays a role in forming certain sounds, particularly ones like "th," "s," and "f," where the tongue or lips need to make contact with or move close to the teeth. Crowding, spacing, or bite misalignment can affect how these sounds come out. Correcting alignment doesn't always resolve speech issues on its own, since other factors can be involved, but it can be part of the picture where dental positioning is a contributing cause.
