Bite Problems: Symptoms, Causes and When to Consider Orthodontic Assessment
Understanding bite misalignment and how a structured orthodontic assessment can help.
What Are Bite Problems?
Bite problems refer to misalignment between the upper and lower teeth when the mouth closes. In dentistry, this is commonly referred to as malocclusion — a term used to describe any variation in the way the teeth fit together. Bite alignment can influence how teeth meet during chewing and speaking, and may have an effect on long-term oral health.
Bite alignment problems may include a range of conditions such as overbite, underbite, crossbite, open bite and deep bite. Each presents differently and may affect individuals to varying degrees. It is important to note that only a clinical examination can determine whether bite alignment requires orthodontic treatment.
If you would like to learn more about , our conditions hub provides a detailed overview of common orthodontic presentations.
Types of Bite Misalignment
The following are among the most common types of bite problems. Each may vary in severity and may or may not require treatment depending on individual circumstances.
Overbite
An overbite occurs when the upper front teeth overlap the lower teeth vertically beyond normal range. While a small degree of overlap is typical, an excessive overbite may affect bite function and tooth wear over time.
Underbite
An underbite is present when the lower teeth sit in front of the upper teeth when biting. This type of bite misalignment may be related to jaw size differences or tooth positioning.
Crossbite
A crossbite occurs when one or more upper teeth bite inside the lower teeth, rather than sitting slightly outside. This can affect the front teeth, back teeth, or both sides of the mouth.
Open Bite
An open bite is characterised by the upper and lower teeth not meeting when the mouth closes, leaving a visible gap between the biting surfaces. This may influence chewing efficiency.
Deep Bite
A deep bite involves excessive vertical overlap of the upper front teeth over the lower teeth. In some cases, the lower teeth may contact the gum tissue behind the upper front teeth.
Symptoms Associated with Bite Problems
The symptoms associated with bite misalignment can vary widely. Not everyone with bite problems experiences discomfort, and the presence of symptoms does not necessarily indicate the need for treatment without a clinical evaluation.
Uneven Tooth Wear
When teeth do not meet evenly during chewing, certain areas may experience greater contact than others. Over time, this may contribute to uneven wear patterns on the biting surfaces.
Jaw Discomfort
Bite misalignment may place additional strain on the jaw muscles during biting or chewing. Some individuals notice intermittent discomfort or tension around the jaw area.
Difficulty Chewing Certain Foods
Bite alignment may influence how efficiently food is broken down during chewing. Individuals with notable bite problems sometimes find certain textures more difficult to manage.
Changes in Speech or Bite Comfort
Some individuals notice that their bite feels imbalanced during speaking or that certain sounds are more difficult to articulate clearly. These changes may or may not be related to bite alignment.
What Causes Bite Problems?
Bite misalignment may develop due to a combination of factors. The following are commonly associated with malocclusion, although each case is individual and a definitive cause may not always be identifiable.
Genetic Jaw Growth Patterns
The size and shape of the jaw are largely influenced by genetics. Differences in upper and lower jaw development may contribute to bite alignment problems.
Tooth Crowding or Spacing
When teeth are crowded or spaced irregularly, they may not meet in an even, balanced position, potentially affecting bite alignment.
Differences in Jaw Size
A mismatch between the size of the upper and lower jaw may result in an overbite, underbite or other forms of malocclusion.
Childhood Habits
Habits such as thumb sucking or prolonged use of a dummy during childhood may influence jaw development and tooth positioning over time.
Early or Late Loss of Baby Teeth
When baby teeth are lost earlier or later than expected, adult teeth may erupt in suboptimal positions, contributing to bite misalignment.
Tooth Shifting Over Time
Teeth can gradually shift throughout adulthood due to natural changes, which may alter bite alignment even in individuals who previously had well-aligned teeth.
Previous Orthodontic Relapse
In some cases, teeth that were previously straightened may shift back towards their original positions if retention was not maintained, potentially affecting the bite.
How Dentists Assess Bite Alignment
A structured orthodontic assessment typically involves several clinical steps to evaluate how the teeth and jaws function together. Treatment suitability depends on the findings from a full assessment.
Visual examination of tooth alignment and positioning
Bite analysis when the teeth close together to evaluate how the upper and lower arches relate
Measurement of tooth overlap and spacing to identify areas of concern
Evaluation of jaw function, including range of motion and comfort
Assessment of tooth wear patterns that may indicate uneven bite loading
Radiographs or digital scans where clinically indicated to provide a more detailed view of bone and root positioning
Concerned About Your Bite?
If you are concerned about bite problems or notice discomfort when chewing, an orthodontic assessment can help determine whether treatment may be beneficial.

Bite Correction Options
The appropriate approach to managing bite problems depends on the nature and severity of the misalignment. The following options may be considered as part of a treatment plan.
Orthodontic Treatment
Orthodontic treatment aims to gradually reposition teeth to improve how the bite fits together. Options may include traditional braces or , which use a series of custom-made trays to guide teeth into improved alignment over time. The suitability of orthodontic bite correction depends on the clinical findings from an assessment.
- Braces — fixed appliances that apply continuous pressure to move teeth
- Clear aligners — removable trays designed for gradual tooth repositioning
- Gradual repositioning of teeth to improve bite alignment and function
Monitoring
If bite misalignment is mild and not currently causing complications, a clinician may recommend monitoring the situation over time. Regular check-ups allow any changes to be identified early, and treatment can be discussed if the situation develops.
Restorative Considerations
In some situations, restorative dentistry may help manage tooth wear associated with bite imbalance. Where teeth have been significantly affected by uneven contact over time, restorative approaches may be considered alongside or independently of orthodontic treatment. Your clinician can advise on the most appropriate approach during your .
Can Bite Problems Affect Jaw Health?
Severe malocclusion may contribute to muscle strain in the jaw area. In some cases, bite imbalance may be associated with symptoms affecting the jaw joints, such as clicking, discomfort or limited range of motion. However, the relationship between bite alignment and jaw joint symptoms can be complex and is not always straightforward.
A structured orthodontic assessment helps determine whether bite alignment may be influencing jaw function. Where relevant, your clinician may discuss how could form part of a broader management plan.
When Should You Consider an Orthodontic Consultation?
There is no single threshold that determines when an orthodontic consultation is appropriate. However, you may wish to consider booking an assessment if any of the following apply to you.
- Your bite feels uneven or uncomfortable
- Chewing causes jaw strain or discomfort
- Teeth appear misaligned when biting together
- You are considering clear aligner treatment
- Tooth wear is becoming noticeable
Frequently Asked Questions
What are bite problems in dentistry?
Bite problems, also known as malocclusion, refer to any misalignment in how the upper and lower teeth fit together when the mouth closes. This may include conditions such as overbite, underbite, crossbite, open bite or deep bite. The severity and impact of bite problems varies between individuals, and a clinical assessment is required to determine whether treatment is appropriate.
Can clear aligners correct bite problems?
Clear aligners may be suitable for correcting certain types of bite misalignment, depending on the nature and severity of the case. Mild to moderate bite problems may respond well to aligner therapy, although more complex cases may require alternative or combined approaches. A thorough orthodontic assessment is an effective way to determine which treatment options may be appropriate for your individual situation.
Are bite problems common?
Bite problems are one of the most common dental concerns. Many people have some degree of bite misalignment, although not all cases cause noticeable symptoms or require treatment. Regular dental assessments can help identify changes in bite alignment over time.
Do bite problems always require treatment?
Not all bite problems require treatment. In cases where misalignment is mild and not causing symptoms such as discomfort, difficulty chewing or noticeable tooth wear, monitoring may be recommended. Treatment is typically considered when bite alignment is affecting comfort, function or oral health. Your clinician can advise on the most appropriate approach following an assessment.
