Have you ever wondered why some people’s lower teeth stick out past their upper teeth? This dental issue, called an underbite, can affect more than just a person’s smile.

But the good news is that there are ways to fix it. With the help of orthodontic treatments, underbites can be corrected in both kids and adults.

In this blog, you’ll explore the main treatments used to fix underbites. By the end, you’ll understand how these options can help improve both your smile and your overall dental health.

What Is an Underbite and Why Does It Matter

An underbite happens when the lower teeth stick out farther than the upper teeth. This can be caused by jaw shape, growing patterns, or habits like thumb-sucking. Some people are born with it, while others develop it over time.

Underbites can be mild or more serious. Even if it seems small, it’s still a good idea to visit a dentist or orthodontist.

They can check if treatment is needed. If not treated, an underbite can lead to jaw pain, chewing problems, or feeling less confident about your smile.

Causes of Underbites You Should Know

Many things can cause an underbite. In most cases, it runs in families. This means if your parents or siblings have one, you might have one too.

Another cause is jaw growth problems. Sometimes, the lower jaw grows faster than the upper jaw. This causes the lower teeth to move forward.

Habits in early childhood can also be a cause. For example, sucking on thumbs or using a pacifier for too long can slowly push the teeth out of place.

Injuries to the face or jaw that heal poorly can lead to an uneven bite as well. Knowing what causes underbites can help in finding the right treatment early.

How Braces Help in Fixing Underbites

One of the most common ways to fix underbites is through braces. Braces work by slowly moving the teeth into better positions.

They are made up of small brackets and wires that apply gentle pressure over time. This method works well, especially in younger patients whose bones are still growing.

There are different kinds of braces, including metal braces, ceramic braces, and clear aligners. Traditional metal braces are strong and often the fastest to fix the problem.

Ceramic braces blend in better with the teeth. Clear aligners are clear plastic trays that are changed every few weeks. All of these can help bring the teeth into better alignment.

Braces are not only used to move teeth. In some cases, they also help guide the jaw into the right spot.

This is why many orthodontists choose braces when dealing with underbites. Treatment may take a few months to a few years, depending on how serious the case is.

When Headgear or Expanders Are Needed

In some cases, braces alone are not enough. For growing children, special tools like headgear or palatal expanders may be used.

Headgear is worn around the head and helps slow the growth of the lower jaw while guiding the upper jaw forward. It is usually worn at night or for a few hours during the day.

A palatal expander is a device that fits in the roof of the mouth. It slowly pushes the upper jaw to grow wider.

This makes more room for the teeth to move into the right position. These devices are most effective when used early, before the jawbones stop growing.

Both headgear and expanders are usually used along with braces. They help make sure the teeth and jaw line up properly. If used at the right age, they can prevent the need for more serious treatments later on.

How Surgery Helps in Serious Cases

Sometimes, orthodontic treatments like braces or expanders are not enough. In serious underbite cases, jaw surgery may be needed.

This is called orthognathic surgery. It is usually only done when the person has finished growing and their bones are fully developed.

During surgery, the bones of the jaw are moved into a better position. The surgeon may shorten the lower jaw, lengthen the upper jaw, or adjust both. After surgery, the bite fits together much better, and the face looks more balanced.

Recovery takes time, and braces may still be needed before or after the operation. While it sounds scary, many people who go through this surgery feel it’s worth it. It helps them chew better, speak more clearly, and feel more confident.

Other Helpful Options for Mild Underbites

Not every underbite needs surgery or strong tools like headgear. For mild cases, clear aligners or retainers can help.

These are custom-made trays that gently push the teeth into a better position. They are easy to take on and off, which makes them a popular choice for adults.

In some cases, tooth extraction may help. Removing one or more teeth can create space for the rest to move into the correct place. Dentists only choose this option when there are too many teeth crowding the mouth.

Some people have an underbite but do not feel any pain or problems. If the underbite is mild and doesn’t affect chewing or speaking, the dentist may suggest keeping an eye on it instead of rushing into treatment.

Why Timing Makes a Big Difference

The earlier an underbite is found, the easier it is to fix. For children, treatments can guide the jaw as it grows.

This makes it easier to get good results. Adults can still get treatment, but it might take longer and require more tools or even surgery.

Regular dental checkups are the best way to catch problems early. Dentists can spot signs of bite issues and send you to an orthodontist for a closer look. Waiting too long can make things harder and more costly.

No matter your age, it is never too late to ask for help. Many people who have an underbite find that treatment improves their lives in more ways than one.
