Overbites and underbites are common dental conditions that can significantly
impact oral health and overall well-being. If you’ve noticed that your
teeth don’t align properly, you may be experiencing one of these malocclusions. Both conditions can lead to a
range of complications, affecting not only your smile but also your ability
to eat, speak, and maintain a positive self-image.
Here, we will share more on the differences between overbites and underbites, the
factors that contribute to their development, the potential problems they can cause,
and the various treatment options available.
What Is an Overbite or Underbite?
An overbite is when the upper front teeth overlap the lower front teeth when
the mouth is closed. In contrast, an underbite occurs when the lower front
teeth protrude past the upper front teeth. These misalignments can create a
more pronounced upper or lower jaw, affecting the functionality of a
person’s bite and facial symmetry.
Both conditions can vary in severity, ranging from mild cases that often do
not require treatment to more significant misalignments that can
substantially impact oral health and daily life.
What Causes an Overbite or Underbite?
Both overbites and underbites can develop due to a combination of factors, including:
- Genetic Predisposition: Inherited jaw shapes and sizes significantly influence teeth alignment, with family history increasing the likelihood of malocclusion.
- Habits: Childhood behaviours like thumb-sucking and prolonged pacifier use can disrupt proper teeth alignment, while habits such as nail biting and bruxism (teeth grinding) may place undue pressure on the teeth and jaw.
- Dental Issues: Premature loss of primary teeth, tooth wear, decay, and crooked teeth can disrupt normal tooth growth and alignment.
- Injury: Trauma to the jaw or teeth can shift their alignment, affecting how the upper and lower teeth meet.
Types of Overbite and Underbite
Overbites and underbites can be classified into two types, or as a combination of both, depending on their causes:
- Dental (Acquired): This type relates to issues with the positioning and alignment of the teeth and surrounding oral tissues.
- Skeletal (Developmental): This type involves the development of the underlying jaw structure and bone growth. It encompasses factors such as the shape and size of the jaw, which can significantly affect teeth alignment.
Problems Caused by Overbite and Underbite
If left untreated, these malocclusions can lead to a range of long-term problems:
Further Dental Issues
Improper positioning can cause uneven wear on teeth, making them difficult to clean properly and increasing the risk of tooth decay and gum disease. Additionally, misaligned teeth can exert excessive pressure on the gums, resulting in inflammation and potential gum damage over time.
Problem in Chewing and Eating
An altered bite can make it challenging to close the mouth comfortably, leading to inefficient chewing and discomfort while eating. This can affect food choices and may contribute to nutritional deficiencies and digestive problems.
Speech Difficulties
Teeth misalignment can disrupt normal tongue placement and airflow, leading to unclear pronunciation and enunciation. This may manifest as difficulty articulating specific sounds, resulting in a lisp or noticeable changes in vocal quality.
Sleep Disruptions
Overbites and underbites can contribute to sleep issues, such as obstructive sleep apnea, where jaw misalignment blocks the airway during sleep. Additionally, these conditions may lead to bruxism and increased snoring, both of which can disrupt sleep quality and disturb partners.
Chronic Pain
Overbites and underbites can lead to chronic jaw pain due to structural misalignment and may also contribute to headaches or ear pain. Additionally, these conditions can result in the development of Temporomandibular Joint (TMJ) disorders, causing discomfort and limited jaw movement.
Negative Self-Image and Esteem
A protruding upper or lower jaw, or an uneven smile, can create a perceived imbalance in facial appearance. This can negatively impact self-esteem and confidence, potentially leading to social anxiety and affecting interpersonal interactions and relationships.
Treatment Options for Overbite and Underbite
Depending on the severity of your condition, there are several treatment options available:
| Treatment Options | Description |
|---|---|
| Braces | Traditional metal braces remain a highly effective orthodontic method for correcting misalignments. Comprising brackets and wires, they gradually shift teeth into proper alignment over a treatment period that typically ranges from 1 to 3 years, depending on the severity of the case. |
| Clear Aligners | Clear aligners, such as Invisalign®, provide a discreet yet effective alternative for bite correction. Utilising a series of custom-made, removable trays, they gently reposition teeth over a period of 12 to 18 months, depending on individual needs. Clear aligners are typically comparable in price or more expensive than traditional braces. |
| Retainers | After completing orthodontic treatment, retainers are often prescribed to maintain new tooth positions. It is generally recommended to wear them full-time for the first few months, transitioning to nighttime wear, potentially indefinitely, to help prevent relapse and ensure alignment as the jaw stabilises. |
| Jaw Surgery | Surgical intervention aims to realign the jawbones for improved function and aesthetics. This option is usually considered for adults with severe cases of significant malocclusions that cannot be corrected through orthodontic means alone. Recovery can take several weeks, and post-surgical orthodontics may be necessary to achieve optimal results. |
It is best to consult a dentist for an assessment to determine the most appropriate treatment for your specific situation.

Yes, an overbite can be corrected using various treatment options, including braces, clear aligners (like Invisalign), or in some cases, jaw surgery. The appropriate treatment depends on the severity of the overbite.
In some cases, overbites can worsen with age due to changes in bone structure, wear on the teeth, or ongoing habits like teeth grinding. Regular dental check-ups can help monitor any changes.
Attractiveness is subjective and varies from person to person. However, many people prefer a balanced and symmetrical smile. A dental professional can offer insights into how these conditions affect overall appearance.
Underbites can create an imbalanced facial appearance, which some people may find less attractive. However, perceptions of attractiveness are subjective and can vary widely among individuals.
Ignoring an overbite can lead to various complications, including tooth wear, gum disease, jaw pain, difficulty chewing, and speech issues. It’s important to consult a dentist for proper assessment and treatment options.
Not everyone with an overbite will need braces. The necessity for braces depends on the severity of the overbite and its impact on oral health. A dental professional can recommend the best course of action.
