How-to-Fix-an-Underbite:-Best-Treatments-and-Results
An underbite is more than just a cosmetic concern. When the lower teeth sit in front of the upper teeth, it can affect chewing, speech, jaw comfort, and long-term oral health. The good news is that modern dentistry offers several effective ways to fix an underbite, and treatment today is more comfortable and discreet than many people expect.
Whether you’re exploring options for yourself or your child, understanding the best treatments and realistic results can help you make a confident decision.
Why Fixing an Underbite Matters
Correcting an underbite isn’t just about achieving a straighter smile. Left untreated, an underbite can place excessive strain on the jaw and teeth, leading to uneven wear, jaw pain, headaches and difficulty biting or chewing food properly. In some cases it can even contribute to speech issues or breathing concerns.
From an aesthetic point of view, an underbite can also affect facial balance, particularly the profile, making the lower jaw appear more prominent. Fixing it can improve both function and facial harmony, often with life-changing results.
What Causes an Underbite?
Underbites usually develop due to genetics, where the lower jaw grows longer or the upper jaw doesn’t develop fully. Childhood habits such as thumb sucking, prolonged pacifier use or mouth breathing can also contribute. In adults, trauma or jaw alignment issues may worsen an existing underbite over time.
The cause and severity of the underbite play a major role in determining the most suitable treatment.
Best Treatments for Fixing an Underbite
The right treatment depends on age, severity, jaw structure and overall oral health.
Braces
Traditional braces are one of the most effective treatments for mild to moderate underbites, especially in teenagers and young adults. By gradually moving the teeth into better alignment, braces can correct the bite and improve function. Treatment typically takes between 18 to 24 months, depending on the complexity of the case. In growing children, braces can also guide jaw development, reducing the need for more invasive treatment later.
Clear Aligners
Clear aligners such as Invisalign can be an option for mild underbites where the issue is mainly dental rather than skeletal. These custom-made trays gently move the teeth into position while remaining nearly invisible. Aligners are popular with adults who want a discreet option, but they do require discipline, as they must be worn for most of the day. Not all underbites can be treated this way, so a thorough assessment is essential.
Early Orthodontic Treatment for Children
When an underbite is identified early, usually between the ages of 7 and 10, interceptive orthodontic treatment can make a significant difference. Appliances such as expanders or functional devices can guide jaw growth and prevent the underbite from becoming more severe. Early treatment often reduces the need for later treatment and can sometimes eliminate the need for surgery altogether.
Jaw Surgery
In cases where the underbite is caused by significant jaw misalignment, orthodontics alone may not be enough. Orthognathic (jaw) surgery may be recommended for adults with severe skeletal underbites.
This treatment involves repositioning the jaw to achieve proper alignment and is usually combined with braces before and after surgery. While it sounds daunting, jaw surgery can dramatically improve bite function, facial balance and overall quality of life. Recovery takes time but the long-term results are often transformative.
What Results Can You Expect?
The results of underbite treatment are generally very positive when the right approach is chosen. Patients often notice improved chewing efficiency, reduced jaw discomfort, and a more balanced facial appearance. Cosmetically, correcting an underbite can soften the profile and create a more harmonious smile. Functionally, it reduces uneven tooth wear and lowers the risk of future dental problems.
Results are long-lasting when followed by proper retention, such as wearing retainers as advised. Like all orthodontic treatments, commitment and aftercare play a key role in maintaining results.
How Long Does Underbite Treatment Take?
Treatment time to fully correct an underbite varies depending on the method used and the severity of the case. Mild cases treated with aligners may take around 12 months, while braces typically require 18 to 24 months. Surgical cases can take longer overall due to preparation, recovery and finishing orthodontic work. Your dentist or orthodontist will provide a personalised timeline after assessing your bite.
Is the Treatment Worth It?
For most patients, fixing an underbite is absolutely worth it. Going beyond improving appearance, it enhances oral function, comfort and long-term dental health. Many patients report increased confidence and improved quality of life once treatment is complete. Early intervention often leads to simpler treatment, but it’s never too late to explore your options. Advances in orthodontics mean adults now have more choices than ever before.
