How to Fix an Underbite with Braces | Expert Advice on Underbite Braces

Dentist explaining the procedure to the patient

Did you know a misaligned bite can cause more than just a cosmetic issue? An underbite can lead to various dental and health problems, such as tooth decay, jaw pain, and difficulty chewing. But don’t worry! Orthodontic treatments offer effective solutions to correct this condition, with braces being a popular option. In this blog post, we will explore the nature of underbites, their causes, and the different treatment options available. So brace yourself for expert advice on underbite braces!

First, let’s take a quick look at the difference between overbite and underbite.

Overbite vs Underbite

An overbite or Class II malocclusion occurs when the upper teeth overlap with the lower teeth making the lower jaw smaller. This can be mild overbite or severe overbite. In underbite or Class III malocclusion, the lower teeth protrude beyond the upper front teeth when the jaws are closed. This condition may lead to severe underbites.

Why Do We Have Underbite Teeth?

An underbite is a dental condition causing an improper bite. Individuals with underbite teeth may experience a range of challenges in their daily lives, such as difficulty chewing, jaw problems, speech impediments, and even the need for tooth extraction or dentures at an early age. Thankfully, in many cases, an underbite can be corrected without surgery.

A variety of factors, including genetics, childhood habits, and dental conditions, can cause underbites. Let’s explore these causes to understand their role in developing the dental disorder.

Genetic Factors

Genetics can play a significant role in the development of underbites, as it is an inherited condition from parents or relatives. Genetic factors can impact the tooth shape and size of the jawbones and teeth, leading to misalignment. This hereditary influence can result in a predisposition to underbites in some individuals.

Childhood Habits

Certain bad childhood habits can contribute to the development of an underbite. These include thumb sucking, prolonged pacifier use, long-term bottle feeding, and tongue thrusting. To prevent underbite development, addressing these habits early on is essential to encourage proper oral hygiene practises, such as regular brushing and flossing.

Dental Issues

Dental issues, such as overcrowding or crooked teeth, missing teeth, or misaligned teeth, can also lead to the development of an underbite. Regular dental check-ups and proper oral hygiene can help identify and address these issues early on, reducing the risk of developing a severe underbite.

Even a mild underbite should not be neglected, as the ideal resting position of the lower front teeth should be behind the upper teeth. Leaving an underbite untreated can lead to excessive wear on tooth enamel, tooth decay, and jaw pain. So, it’s essential to address underbites to prevent further dental problems.

Types of Underbite

There are two main types of underbites: dental and skeletal. Dental underbites involve teeth misalignment, while skeletal underbites result from jaw misalignment. In severe underbite cases, a combination of braces and jaw surgery may be recommended. Let’s delve into these two types of underbites and their implications.

Dental Underbite

A dental underbite occurs when the lower teeth overlap beyond the upper teeth. This misalignment can lead to accelerated tooth wear, enamel erosion, and expedited tooth decay. If left untreated, dental underbites can cause discomfort during eating, teeth grinding (bruxism), headaches, and potential temporomandibular joint disorder issues.

It’s crucial to address dental underbites early to prevent these complications. Treatment options for dental underbites may include orthodontic solutions like traditional braces, retainers, or clear aligners to guide the teeth into their correct position.

Skeletal Underbite

A skeletal underbite is characterised by a jawbone misalignment, causing the lower jaw to protrude forward. This is typically hereditary and results from jawbone malformations.

Addressing skeletal underbites may require more than just orthodontic treatment. Depending on the severity, surgical intervention (orthognathic surgery) may be necessary to correct the jawbone malformation and achieve proper alignment.

Understanding the specific type of underbite will help your dentist choose the effective treatment approach.

How to Fix Underbite

Orthodontic treatment with braces can effectively fix an underbite by repositioning the teeth and adjusting the jawbone tissue.

Braces use a system of brackets, wires, and bands to exert constant pressure on the teeth, gradually shifting them into their correct positions. By aligning the teeth properly, braces help bring the upper and lower jaws into better harmony, reducing the severity of the underbite.

In some cases where skeletal issues primarily cause the underbite, braces alone may not be sufficient. However, braces can be combined with other orthodontic appliances, such as jaw expanders, headgear or functional appliances, to help adjust the position of the jaws and correct the underbite.

The treatment method or the type of braces used will depend on the specific case and patient preferences. In the following section, we will discuss the various types of braces available for underbite correction and their advantages.

Underbite Braces: How braces fix underbites

When it comes to correcting underbites, there are several options for braces, including traditional metal braces, ceramic braces, and Invisalign clear aligners. Let’s explore each of these options in more detail.

Traditional Metal Braces

Traditional metal braces are a common orthodontic treatment for correcting underbites. They consist of metal brackets bonded to the teeth and connected by a wire, which exerts gentle pressure on the teeth to gradually shift them into proper alignment.

While other orthodontic options are available, such as clear braces or functional appliances, traditional metal braces offer extensive flexibility and a wide selection of customisation options, making them widely used and proven effective in correcting underbites.

One advantage of traditional metal braces is their affordability. However, they are also the conspicuous option. For those more concerned about aesthetics, ceramic braces or Invisalign may be suitable as alternative options.

Ceramic Braces

Ceramic braces are a type of orthodontic appliance that can be used to correct various dental alignment issues, including underbites. They are the same in shape and style as their metal counterpart. However, they provide a more subtle look due to the specific ceramic composite material.

One of the key advantages of ceramic braces is their ability to exert controlled pressure on the teeth, gradually moving them into the proper positions. The braces consist of brackets made from a clear or tooth-coloured ceramic material that blends with the natural colour of the teeth, making them less noticeable.

While ceramic braces are less noticeable than traditional metal braces, they are more expensive. However, for patients who prefer a discreet look, ceramic braces can be a great option for underbite treatment.


Invisalign clear aligners are a popular orthodontic treatment option for teeth straightening that can effectively correct dental misalignments, including underbites. This condition can lead to difficulties in biting, chewing, and speaking, as well as aesthetic concerns. Fortunately, Invisalign aligners offer a discreet and comfortable solution for addressing underbites, as the clear aligners are virtually invisible and can be removed for eating, brushing, and flossing.

It consists of a series of clear, removable trays that are custom-made to fit the patient’s teeth. Each successive tray is slightly more aligned than the previous one, gradually shifting the teeth into the right position over time, closer to your desired alignment goal.

Invisalign may be suitable for mild underbite to complex underbite cases, but more severe cases may require additional treatment methods like underbite jaw surgery to achieve good results.

Begin Your Braces Treatment

The orthodontic treatment process for underbite correction generally involves three main steps: an initial consultation, a personalised treatment plan, and periodic adjustments. Understanding each step of the process makes patients feel confident and informed about their underbite treatment journey.

Once you and your dentist have decided on the appropriate suitable type of braces, the treatment process will begin. Here’s what you can expect:

Initial Consultation

During the initial consultation, our dentist will assess your underbite status—conducting a comprehensive examination, including X-rays, impressions, and photographs of your teeth and jaws—discuss potential treatment options, and determine the appropriate course of action. This initial assessment is crucial for creating a customised treatment plan tailored to your needs.

Before starting braces treatment, it’s important to clearly understand the process and address any concerns you may have to give you specific advice. Here are some questions to ask your dentist before starting braces treatment:

  • What braces are available, and which would suit my case?
  • How long is the expected duration of the braces treatment?
  • What changes can I expect in my teeth and bite after the treatment?
  • Will I need any extractions or other dental procedures before getting braces?
  • How often will I visit for adjustments and check-ups during the treatment?
  • Will braces affect my speech or eating habits during the treatment?
  • How should I take care of my braces and maintain good oral hygiene throughout the treatment?
  • Will wearing braces be painful or uncomfortable, and how can I manage any discomfort?
  • Are there any dietary restrictions or habits I should avoid while wearing braces?
  • Will I need to wear a retainer after the braces are removed, and how long?
  • How much will the braces treatment cost, and are there any payment plans or insurance coverage options available?
  • Can you show me before and after photos of patients with similar cases who have completed braces treatment?

Remember, asking these questions might help you make informed decisions about your treatment and ensure that you have realistic expectations throughout the process.

Customised Treatment Plan

After the initial consultation, our dentist will create a customised treatment plan for underbite correction, which may involve a combination of orthodontic appliances, such as braces, retainers, or expanders. Depending on the severity of the underbite, surgical intervention may also be necessary.

A personalised treatment plan is important to give the patient a clear understanding of the treatment journey and goals.

Ongoing Adjustments

Throughout the treatment process, periodic adjustments will be made to the orthodontic appliances to gradually move your teeth and jaw into the desired position. These include making necessary modifications and tightening the wires to continue the alignment process. The duration and frequency of these adjustments will depend on the severity of the underbite and the type of braces used.

Regular dental visits are essential for monitoring progress and ensuring a successful result.

Post-Treatment Care

Once the underbite has been corrected, it is important to maintain the results through post-treatment care. This typically involves wearing retainers and undergoing regular dental check-ups to ensure the teeth remain corrected and maintain good oral health. 

Wear Retainers

Retainers are orthodontic devices used to maintain teeth’ position after braces have been removed. Depending on the patient’s specific needs and preferences, they can be either removable or permanent.

Wearing retainers as prescribed by the dentist is crucial to prevent the teeth from shifting back to their original positions and maintain the underbite correction results.

Regular Dental Check-ups

Regular dental check-ups are essential for maintaining good oral health and preventing future dental problems like gum disease and tooth decay. During check-ups, the dentist will assess the overall health of the teeth and gums and monitor the stability of the underbite correction.

Staying vigilant with dental care can help ensure long-lasting results and achieve a healthy, confident smile.

Expert Advice and Precautions

Underbite correction with braces is a complex process that requires the expertise of a dentist. Here are some expert advice and precautions to consider:

Choose an Experienced Dentist. Look for a dentist who has experience treating underbites and is knowledgeable about the advancements in orthodontic techniques. A skilled professional can develop an effective treatment plan tailored to your needs.

Follow Instructions Carefully. Following your dentist’s instructions regarding oral hygiene, diet restrictions, and wearing elastics or other auxiliary appliances is crucial. Compliance with these instructions will help achieve good results and minimise treatment time.

Be Patient. Underbite correction is a gradual process that takes time. Patience is key, as the duration of treatment may range from several months to a few years, depending on the severity of the underbite.

Maintain Good Oral Hygiene. Proper oral care is essential during orthodontic treatment. Regularly brush and floss your teeth, and use any recommended cleaning aids or mouthwashes to keep your teeth and braces clean. Neglecting this can lead to oral health issues, such as tooth decay or gum disease.

Wear Retainers as Instructed. After the braces are removed, wearing retainers is vital to maintain the corrected position of your teeth. Failing to wear retainers as instructed can result in the relapse of the underbite.
