An underbite is a common dental condition. A person with an underbite will have his or her lower teeth sticking out farther than the upper teeth. If you don’t like the appearance that your underbite gives you, and you’d like to align your smile, or you’re experiencing TMJ pain and so can’t chew, then Beam Australia can help. We offer clear alignment treatment plans and other alternatives to underbite surgery in Australia to align your smile and make it as radiant as you’ve always wanted.


An underbite is also known as prognathism. It is a bad bite or a dental malocclusion caused by the protrusion or overlap of your lower teeth on the upper teeth. In mild cases, you may only have two rows of your teeth meeting. In severe cases, the teeth fail to meet.


An underbite is caused by a misalignment of the lower jaw. This condition is mostly congenital meaning that it occurs naturally. It may develop due to conditions such as basal cell nervous syndrome, acromegaly, or Crouzon syndrome. Also, a person may be genetically prone to this condition. 

The good news, however, is that there are ways to correct it, either through surgical or non-surgical methods.


You may have a problem with dental alignment, but there are non-surgical alternative treatments for an underbite; treatments that can improve your smile and ease the discomforting symptoms that characterize an underbite. 

There are three alternatives to underbite surgery in adults. These are:

  • Clear Aligners.
  • Braces.
  • Cosmetic procedures such as crowns or veneers.

Underbite Surgery is only necessary when the bad bite is caused by a skeletal problem.

Beam clear aligners are less expensive compared to underbite surgery. These alternatives also help you to avoid the pain, long recovery periods, and other discomforts caused by underbite surgery. However, you should remember that opting for an alternative to underbite surgery means taking your oral dental care regimen seriously.

Devices for correcting an underbite

Two important devices can fix an underbite without surgery. They are generally used to correct this condition in young people. 

One is an upper jaw expander. An upper jaw expander fits across your palate. It comes with a key that you can use to widen the upper jaw at night until the outside of your upper teeth no longer closes against your lower teeth. You may also use a “reverse-pull” mask. It resembles headgear braces. You wrap the mask around your head and it pulls your upper jaw into the correct alignment.

To fix an underbite in adults, more advanced solutions will be required because at this time, the musculoskeletal system has stopped growing.


Braces are often used to fix underbites in Australia. However, they can be expensive, uncomfortable, require in-person appointments and generally take a long time to fix your underbite. 

Beam Clear Aligners

Beam clear aligners are used to straighten teeth. Although, can also be used to fix underbites. Beam clear aligners readjust your teeth alignment with transparent aligners. To fix your underbite, you should wear these aligners for at least 22 hours daily and at least a year. 

Not all underbites can be fixed with clear aligners and in severe cases, you may need to extract a tooth or two from the lower jaw to give room for movement of the remaining tooth. You can take a free 30-second smile assessment and contact us to discuss.
