What’s the Difference Between Overbite and Underbite

What's the Difference Between Overbite and Underbite

In the realm of orthodontics, overbites and underbites are common dental conditions that can impact both oral health and aesthetics. Understanding the key differences between these two conditions is essential for proper diagnosis and treatment. In this comprehensive guide, we’ll explore what overbites and underbites are, their causes, and how they can be treated effectively.

What is Overbite and Underbite

An overbite occurs when the upper front teeth overlap significantly with the lower front teeth when the mouth is closed. On the other hand, an underbite occurs when the lower front teeth protrude outward, overlapping the upper front teeth. Both overbites and underbites can vary in severity, ranging from mild to severe, and may require orthodontic intervention to correct bite problems.

Causes of Overbite and Underbite


In many cases, overbites and underbites have a genetic component, meaning they can be inherited from one or both parents. Individuals with a family history of these conditions may be more prone to developing them themselves.

Thumb Sucking or Pacifier Use

Prolonged thumb sucking or pacifier use during childhood can contribute to the development of malocclusions, including overbites and underbites. These habits can exert pressure on the teeth and jaws, leading to misalignment over time.

Jaw Structure

Differences in jaw size or shape can also contribute to the development of overbites and underbites. For example, a small lower jaw or a larger upper jaw can result in an overbite, while a small upper jaw or a larger lower jaw can lead to an underbite.

Difference Between Overbite and Underbite

Dental Position

The primary distinction between overbite and underbite lies in the position of the upper and lower teeth when the mouth is closed. In an overbite, the upper front teeth overlap the lower front teeth, while in an underbite, the lower front teeth protrude forward, overlapping the upper front teeth.

Impact on Facial Aesthetics

Overbite and underbite can affect facial aesthetics differently. An overbite may result in a gummy smile or protruding upper lip, while an underbite can give the appearance of a protruding lower jaw or chin.

Functional Differences

Overbite or underbite can also impact bite function differently. Individuals with an overbite may experience difficulty biting and chewing certain foods, while those with an underbite may have challenges with speech articulation and jaw movement.

Can Braces Fix an Underbite

Orthodontic Treatment

Braces are a common treatment option for correcting malocclusions, including underbites. By applying gentle pressure to the teeth and jaws, braces gradually shift them into proper alignment, correcting the underbite over time.

Orthognathic Surgery

In severe cases of underbite where orthodontic treatment alone may not be sufficient, orthognathic surgery may be recommended. This surgical procedure involves repositioning the upper or lower jaw to correct the underlying skeletal imbalance contributing to the underbite.

How to Fix Underbite Naturally

While orthodontic treatment and surgery are the most effective ways to correct underbites, there are some natural approaches that may help alleviate symptoms or prevent further progression:

Oral Exercises

Certain oral exercises, such as tongue thrust exercises or jaw strengthening exercises, may help improve jaw alignment and muscle function over time.

Healthy Lifestyle Habits 

Maintaining a balanced diet rich in essential nutrients and avoiding habits like thumb sucking or nail biting can promote optimal dental and jaw development, reducing the risk of underbites and other malocclusions.

Overbite vs Regular Bite

A regular bite, also known as a normal or ideal bite, occurs when the upper and lower teeth meet in proper alignment without any significant overlap or protrusion. In contrast, an overbite involves the upper front teeth overlapping the lower front teeth, while an underbite involves the lower front teeth protruding forward.
