What to Do if Your Bottom Teeth Protrude in Front of Your Top Teeth?
Posted on 6/15/2026 by Mountain State Oral and Facial Surgery |
 Having your bottom teeth stick out further than your top teeth, a condition dentists call an "underbite," can affect more than just your smile. It can impact how you chew, speak, and even breathe. Let's explore what an underbite is and what you can do about it.
Understanding Underbite
An underbite, also known as a Class III malocclusion, happens when your lower jaw grows more than your upper jaw. Sometimes, it's the opposite – the upper jaw doesn't grow enough. Genetics often play a big role in determining jaw size, but childhood habits like thumb-sucking or prolonged pacifier use can also contribute.
Why Correcting an Underbite Matters
Beyond aesthetics, an underbite can cause several problems. The uneven bite can put extra stress on certain teeth, leading to premature wear and tear, chipping, or even fractures. This unevenness can also make it difficult to properly clean your teeth, increasing the risk of cavities and gum disease.
Furthermore, an underbite can strain the jaw muscles, resulting in temporomandibular joint (TMJ) disorders. These disorders can cause pain in the jaw, face, and neck, along with headaches and clicking or popping sounds when you open or close your mouth. Speech impediments and difficulty chewing food efficiently are other potential consequences.
What Can You Do?
The good news is that underbites are often correctable, especially when addressed early. Treatment options vary depending on the severity of the underbite and the patient's age.

Early Intervention: In children, orthodontists can use appliances like palatal expanders or headgear to guide jaw growth and correct the underbite as the child develops. These appliances help to widen the upper jaw or restrain the growth of the lower jaw, encouraging proper alignment. |
| • |
Orthodontic Treatment: For teens and adults, braces or clear aligners are common options. Orthodontic treatment can move the teeth into a more ideal position, improving the bite. However, orthodontics alone may not be enough to correct a severe underbite. |
| • |
Orthognathic Surgery: In cases where the underbite is significant, orthognathic surgery, also known as corrective jaw surgery, might be necessary. This involves surgically repositioning the upper and/or lower jaw to achieve proper alignment. Orthognathic surgery is often combined with orthodontic treatment to optimize the results. |
| • |
Restoration Dentistry: In some cases, an underbite may cause significant wear and tear on the teeth. After the jaw alignment has been corrected, restorative procedures may be needed to rebuild damaged teeth. Options might include crowns, veneers, or other treatments to restore the teeth's shape, function, and appearance. |
Maintaining Good Oral Care
Regardless of whether you pursue treatment for an underbite, maintaining excellent oral care is essential. This includes brushing your teeth at least twice a day, flossing daily, and visiting your dentist for regular checkups and cleanings. Using a fluoride mouthwash can also help to protect your teeth from cavities. If you are undergoing orthodontic treatment, your dentist or orthodontist can provide specific instructions on how to properly care for your teeth and appliances.
Seeking Professional Guidance
If you suspect you or your child has an underbite, consulting with a qualified dentist or orthodontist is the first step. They can evaluate your bite, take X-rays, and recommend the most appropriate treatment plan based on your individual needs. Early detection and intervention can often prevent more serious problems from developing later in life. Take control of your oral health and speak to a professional.
