underbite

An underbite is one of the most common dental defects, in which the lower teeth extend further than the upper teeth when the mouth is shut. This misalignment can interfere with aesthetics and oral function, making it harder to chew, speak, and even breathe.

In this blog entry, we will look at the causes of underbites, the treatments available, and how you can fix an underbite to improve your life.

Understanding Underbites

An underbite is when the lower jaw extends beyond the upper jaw. This condition is often classified into two categories:

  • Skeletal Underbite: The reason for this is an uneven growth of the upper and lower jaw. Genetics and environmental exposures during development can all contribute to this disorder.
  • Dental Underbite: This is caused by what is called a malocclusion of the teeth, not the mandible (jawbone). Dental underbites can occur due to habits like thumb sucking, prolonged bottle feeding, or the early loss of primary teeth.

What Causes an Underbite?

The majority of underbites originate from the maxilla, which is relative to the mandible. Several factors contribute to the development of this condition:

Genetics

There is a genetic basis for much of the etiology of an underbite. When one or both parents have suffered the same kind of dental defect, their children are more likely to develop that dental defect, which is an underbite in this case.

Jaw Misalignment

Jaw misalignment can occur due to several reasons, including:

  • Early loss of baby teeth: If a child loses their milk teeth too soon or too late, it can disrupt the position of their permanent teeth and jaws.
  • Prolonged thumb sucking: Sucking an index finger too long can alter the jaw, causing an underbite in children.

Certain Habits

Mouth breathing: Breathing through the mouth instead of the nose can change the contours of the mouth and face.

Jaw clenching or teeth grinding: Those habits strain the jaw and change its shape over the years.

Environmental Factors

Bad teeth, lack of orthodontic intervention in childhood, and certain medical conditions can all be the cause of misaligned teeth and jaws.

Recognizing the Symptoms of an Underbite

It's important to know the signs of an underbite so that it can be treated in its early stages. Some common signs include:

  • Protruding lower teeth
  • Difficulty in biting or chewing food
  • Speech difficulties
  • Jaw pain or discomfort
  • Increased wear and tear on the teeth

If any of these symptoms occur, you should seek the attention of a dentist as soon as possible for a complete examination.

Treatment Options for Fixing an Underbite

For example, several things can be done if one has an underbite. What to do is not always clear, and it often depends on the severity of the underbite, the patient's age, and overall oral health. Here are some common treatment methods:

Orthodontic Treatments

a. Braces

For most people, the usual treatment is to fix the underbite with metal brackets. They just gradually force the teeth in. It works well on children and adults alike.

b. Clear Aligners

For those who want something less conspicuous, there are also clear braces, such as those offered by Smilepath, which can treat mild to moderate underbites. These clear aligners are individually crafted to fit tightly over your teeth and, over time, nudge them into place. The benefits of clear aligners include:

  • Aesthetically pleasing: They are nearly invisible, making them a popular choice for adults and teenagers.
  • Comfort: Advertised as being made of smooth plastic so they don't tickle or rub the gums like normal braces.
  • Convenience: The brackets are removable for eating and for brushing or flossing, so they also encourage good oral hygiene.

Smilepath offers inexpensive clear braces, which are a good option for an underbite, especially if one is not looking to wear braces.

Surgical Options

In extreme underbites, surgery is often required. Orthognathic surgery, or jaw surgery, is a procedure performed to fix the jawbones in place. It's the standard for adults with severe jaw misalignment who are looking to get their bites and jaws to work normally.

a. Pre-Surgical Orthodontics

The patients usually have to wear these braces on for a while, and then they can go in for surgery to fix their teeth. Such preparation guarantees that the bite can be surgically corrected precisely.

b. Post-Surgical Orthodontics

Additional orthodontics may be required after the surgery to reposition the teeth. This phase can also optimize the bite rectification process.

Dental Appliances

In other cases, orthodontics such as retainers or palatal expanders can correct an underbite. They work best, however, on younger patients whose jaws are still developing. They can help to build the jaw and allow space for the teeth to fit into a normal occlusion.

The Importance of Early Intervention

It's important to get an underbite fixed as soon as possible. In children, the jaw is still developing and malocclusions can be more readily corrected. Early treatment treats issues and sometimes helps avoid aggressive interventions that are required later on.

Parents should check their children's teeth regularly and consult a dentist if they see the beginnings of an underbite. Dental checks (including orthodontic checks) should be done around age seven, to intervene, if necessary.

Lifestyle Changes and Home Remedies

Maintain Good Oral Hygiene

Good oral hygiene prevents more dental problems. Brush and floss your teeth, because if you have braces or clear aligners, you better have healthy teeth and gums.

Avoid Harmful Habits

Try to eliminate habits that may worsen the underbite, such as thumb sucking or mouth breathing. Teach kids to breathe through their noses and suck their thumbs.

Consult a Professional

Going to the dentist regularly or seeing your orthodontist helps keep your progress going and adjust your treatment plan accordingly.

Frequently Asked Questions

What are the main causes of an underbite?

The most common factors leading to an underbite are genetics, childhood habits (such as thumb sucking and bottle feeding past the age of 2), jaw trauma due to injury, and dental problems such as missing teeth or tooth decay. Equipped with this understanding of the causes, an underbite can be avoided.

How can an underbite be treated?

The treatment for an underbite varies with severity and may involve orthodontics, such as braces or clear aligners, jaw surgery in more severe cases, and retainers to maintain tooth position after treatment. For instance, clear aligners such as those offered by Smilepath can help straighten mild to moderate underbites, and the benefit of clear aligners is that they are less conspicuous than braces.

Is fixing an underbite painful?

Fixing an overbite can also be painful, like when adjusting braces or clear aligners, but that is generally manageable with over-the-counter painkillers. Surgical intervention can be more painful and can require a recovery period, but the level of pain depends on what a person is used to and the severity of the procedure.

How long does it take to fix an underbite?

The length of treatment to correct an underbite varies depending on its severity and the treatment method used. Typically, orthodontic treatment with braces or clear aligners can take anywhere from 6 months to 2 years. Surgical treatments may have a longer recovery period, but your orthodontist will provide a personalized timeline based on your specific situation.

Can an underbite affect my overall health?

Yeah, an underbite does affect the entire body by causing things like jaw pain, trouble with chewing, and even speech. Misalignment can also lead to accelerated tooth wear, gum disease and even breathing difficulties. Treatment of an underbite can prevent these health issues as well as improve your overall quality of life.
