What Is An Underbite?

First off, what exactly is an underbite? Put simply, an underbite is a dental condition in which the lower jaw juts out further than the upper jaw, causing the lower teeth to overlap the upper teeth. There are many potential causes of underbites, including genetics, thumb-sucking, tongue-thrusting, or premature tooth loss. Sometimes, however, underbites can be the result of more serious underlying conditions, such as skeletal abnormalities or bone disorders.

How Does an Underbite Affect a Person's Health?

So what are the potential effects of underbites on your child's health? Well, the most immediately noticeable impact is likely cosmetic. Underbites can result in a less attractive smile, and may cause your child to feel self-conscious or embarrassed. However, the problems aren't just superficial. Untreated underbites can also lead to issues with speech, eating, and other functions that require proper jaw alignment. In severe cases, underbites can even cause chronic pain, headaches, or joint problems.

How to Fix Underbite

So what can you do if your child has an underbite? Fortunately, there are a variety of treatments available, depending on the severity of the condition. For more mild cases, orthodontic treatments such as braces or retainers may be sufficient to correct the problem. For more serious cases, surgery may be necessary to reposition the jaw. While the process may be lengthy or uncomfortable, it's important to address underbites as early as possible to minimize the potential health impacts.

What Causes an Underbite?


Are underbites genetic? Yes — in fact, one of the most common reasons for having an underbite is genetics. If one or both parents have an underbite, their children are likely to inherit it. In some cases, the condition may skip a generation. So, if you or your partner has an underbite, it’s worth asking your parents if they did.


Did you know that your child’s habit of thumb-sucking or pacifier use can cause an underbite? When a child keeps their thumb or pacifier in their mouth for extended periods, it can cause the jaw to shift and lead to an underbite. As parents, it’s important to help your child break this habit as early as possible.

Jaw Misalignment

Jaw misalignments can also cause an underbite. In some cases, the lower and upper jaws may not develop proportionately, which can affect the bite and cause the lower teeth to jut out. Trauma to the jaw can also cause misalignment, so if your child has experienced a blow to the face, keep an eye out for an underbite.


Underbite can also develop as we age, mainly due to changes in the structure of our jaw and teeth. It’s not uncommon for adults to start noticing an underbite in their 50s or 60s. If left unaddressed, an underbite can lead to several health issues, such as tooth decay, gum disease, and speech problems.

Does an Underbite "Need" to Be Treated?

Now, some of you may be thinking, "But my child's underbite isn't causing any problems - should we really bother with treatment?" Well, that depends. While some underbites may not cause noticeable issues, it's important to remember that leaving the condition untreated can cause long-term health problems down the line. Additionally, correcting underbites in childhood can be easier than waiting until later in life, when the jaw has stopped growing, and the treatments may be less effective. So even if your child's underbite seems minor, it's worth consulting with a dental professional to discuss potential treatment options.

Can Braces or Invisalign Fix Underbite?

Underbites may seem like a minor dental issue, but they can have serious impacts on your child's health and well-being. While the causes and treatments of underbites can vary, it's important to address the issue as soon as possible to minimize potential problems down the line. So don't hesitate - if you suspect your child may have an underbite, speak with an orthodontist and start exploring potential treatment options today!
