Malocclusion (Crooked Teeth)

Do you struggle with misaligned teeth or an improper bite? If so, you may be dealing with malocclusion, a common dental condition that affects millions of people worldwide. Malocclusion refers to the misalignment of the teeth when the upper and lower jaw do not fit together properly.

Not only can malocclusion impact your self-esteem and confidence, but it can also affect your overall oral health. Improperly aligned teeth are more difficult to clean, increasing the risk of tooth decay, gum disease, and even tooth loss. Additionally, malocclusion can cause issues with chewing, speaking, and jaw functionality.

Fortunately, there are various treatment options available to correct malocclusion and achieve a healthy, well-aligned smile. From braces and aligners to orthodontic surgeries, your dentist or orthodontist can help determine the best course of action for your specific case.

In this article, we will delve deeper into malocclusion, its causes, types, and the treatment options available. Whether you’re considering orthodontic treatment or simply curious about this dental condition, keep reading to learn more about malocclusion and how it can be effectively addressed.

What is malocclusion?

Malocclusion is a term used to describe the misalignment of teeth and improper positioning of the upper and lower jaws. It can result in various dental and oral health issues, affecting both the appearance and functionality of your smile. Malocclusion can be caused by a combination of genetic and environmental factors.

There are different types of malocclusion, including crowded teeth, spaced teeth, overbite, underbite, crossbite, and open bite. Each type has its own unique characteristics and requires specific treatment approaches.

Types of malocclusion

This type of malocclusion occurs when there is insufficient space in the jaw for all the teeth to fit properly. Crowded teeth can be overlapping, rotated, or twisted, making them difficult to clean and increasing the risk of decay and gum disease.

Spaced teeth, also known as diastema, refer to gaps or spaces between the teeth. This can occur due to missing teeth, small teeth, or an abnormal jaw size. Spaced teeth can affect the aesthetics of your smile and may cause difficulties in chewing.

An overbite occurs when the upper front teeth overlap excessively with the lower front teeth. This can result in the lower teeth biting into the roof of the mouth, leading to potential damage and discomfort. Overbite can also contribute to jaw pain and headaches.

An underbite is the opposite of an overbite, where the lower front teeth protrude beyond the upper front teeth. This can affect the appearance of the face and may cause difficulties in speaking and chewing properly.

Crossbite refers to the misalignment of the upper and lower teeth, where some of the upper teeth bite inside the lower teeth. This can cause tooth wear, gum recession, and jaw misalignment if left untreated.

An open bite occurs when there is a space between the upper and lower teeth even when the jaws are closed. This can affect speech, chewing, and may lead to temporomandibular joint (TMJ) disorders.

Causes of malocclusion

Malocclusion can be attributed to various factors, including:

The size and shape of your jaw, as well as the positioning of your teeth, can be inherited from your parents. If your family has a history of malocclusion, you may be more prone to developing this condition.

Certain childhood habits, such as thumb sucking, tongue thrusting, and prolonged pacifier use, can impact the development and alignment of the teeth and jaw.

Accidents or injuries to the face and jaw can disrupt the alignment of the teeth and result in malocclusion.

If baby teeth are lost too early, it can affect the eruption and alignment of permanent teeth, leading to malocclusion.

Neglecting proper oral hygiene, such as not brushing or flossing regularly, can increase the risk of tooth decay, gum disease, and malocclusion.

Signs and symptoms of malocclusion

The signs and symptoms of malocclusion can vary depending on the type and severity of the condition. Some common signs include:

If you experience any of these symptoms, it’s important to consult with a dentist or orthodontist for a proper diagnosis and treatment plan.

Complications of untreated malocclusion

If left untreated, malocclusion can lead to several complications, including:

Misaligned teeth are more difficult to clean, making them more susceptible to tooth decay, gum disease, and cavities. This can eventually lead to tooth loss if not addressed promptly.

Malocclusion can put stress on the jaw joint, leading to TMJ disorders. This can cause jaw pain, clicking or popping sounds, difficulty in opening or closing the mouth, and headaches.

Severe malocclusion can affect the position of the tongue and lips, leading to speech impediments and pronunciation problems.

The appearance of misaligned teeth can affect your self-esteem and confidence, making you hesitant to smile or speak in public.

Diagnosis of malocclusion

To diagnose malocclusion, your dentist or orthodontist will perform a comprehensive examination, which may include:

Your dentist will ask about any symptoms or concerns you may have regarding your teeth and jaws. They will also inquire about any relevant medical conditions or medications that could contribute to malocclusion.

Your dentist will visually examine your teeth and jaws to identify any obvious signs of malocclusion, such as crooked teeth, gaps, or bite alignment problems.

Your dentist may take dental impressions or molds of your teeth to create a replica of your mouth. This can help them study your bite and plan the appropriate treatment.

X-rays and other imaging techniques may be used to obtain a detailed view of your teeth, jaws, and facial structure. This can help determine the severity of malocclusion and guide the treatment plan

Your dentist may ask you to bite down on a special material to assess the alignment and positioning of your teeth and jaws. This can provide valuable information about your bite and occlusion.

Based on the findings, your dentist or orthodontist will diagnose the type and severity of malocclusion and recommend the most suitable treatment options for your case.

Treatment options for malocclusion

The treatment for malocclusion depends on the type and severity of the condition. Here are some common treatment options:

Braces are the most common orthodontic treatment for malocclusion. They consist of brackets that are bonded to the teeth and connected by wires. Braces gradually apply pressure to the teeth, guiding them into the correct position over time.

Clear aligners, such as Invisalign, are an alternative to traditional braces. These custom-made, removable aligners are virtually invisible and can be taken out for eating and oral hygiene routines. They work by exerting gentle pressure to gradually move the teeth into alignment.

Retainers are often used after orthodontic treatment to maintain the new position of the teeth. They can be removable or fixed and are typically worn for a specified period to prevent relapse.

In some cases, additional orthodontic appliances may be necessary to correct malocclusion. These can include headgear, palatal expanders, or orthognathic surgery.

In severe cases of malocclusion, orthognathic surgery may be required to reposition the jaw. This procedure is typically performed in conjunction with braces or aligners to achieve optimal results.

It’s important to consult with an experienced dentist or orthodontist to determine the most appropriate treatment option for your specific case.

Orthodontic procedures for correcting malocclusion

Orthodontic procedures play a crucial role in correcting malocclusion and achieving a well-aligned smile. Here are some commonly used procedures:

Bonding involves the application of tooth-coloured resin material to the surface of the teeth. This can help reshape and reposition teeth to improve their appearance and alignment.

Enameloplasty, also known as tooth contouring, involves removing small amounts of enamel to reshape the teeth. This procedure can help correct minor alignment issues and create a more harmonious smile.

In some cases of severe crowding or malocclusion, extractions may be necessary to create space for the remaining teeth to align properly. Your dentist or orthodontist will carefully evaluate the need for extractions based on your specific case.

Jaw wiring is a procedure where the jaw is temporarily wired shut to correct severe malocclusion or jaw misalignment. This procedure is typically reserved for extreme cases and is rare in modern orthodontics.

Each orthodontic procedure is tailored to the individual’s specific needs and goals. Your dentist or orthodontist will discuss the available options and recommend the most suitable treatment plan for you.

Preventing malocclusion

While some factors contributing to malocclusion, such as genetics, cannot be controlled, there are steps you can take to minimize the risk of developing this condition. Here are some preventive measures:

Brush your teeth at least twice a day, floss daily, and visit your dentist regularly for check-ups and cleanings. Good oral hygiene can help prevent tooth decay, gum disease, and other dental issues that can contribute to malocclusion.

Discourage thumb sucking, tongue thrusting, and prolonged pacifier use in children. These habits can disrupt the proper development and alignment of teeth and jaws.

Wear a mouthguard during sports or activities that may pose a risk of dental or facial trauma. This can help prevent injuries that could lead to malocclusion.

If you notice any signs of malocclusion in yourself or your child, seek early orthodontic intervention. Early treatment can help guide the growth and development of the teeth and jaws, minimizing the need for extensive orthodontic procedures later in life.

By following these preventive measures and maintaining good oral health, you can reduce the likelihood of developing malocclusion.


Malocclusion is a common dental condition that affects the alignment and positioning of teeth and jaws. It can have significant implications for both oral health and overall well-being. Fortunately, various treatment options are available to correct malocclusion and achieve a healthy, well-aligned smile.

Whether you’re considering orthodontic treatment or simply curious about this dental condition, understanding the causes, types, and treatment options of malocclusion can provide valuable insights.

If you suspect that you or your child may have malocclusion, it’s essential to consult with a qualified dentist or orthodontist. They can assess your specific case, provide an accurate diagnosis, and recommend the most appropriate treatment plan to achieve a beautiful, functional smile.
