Overbite: Causes and Management Options
An overbite describes the vertical overlap of the upper front teeth over the lower teeth. While a small degree of overlap is normal, a more pronounced overbite may affect bite alignment, chewing, and jaw comfort.
Some people notice aesthetic concerns, while others may experience functional symptoms. Professional dental assessment can help evaluate bite position and oral health.
Professional Assessment
A thorough clinical evaluation can assess bite alignment, identify any effects on tooth wear or jaw function, and help determine the most appropriate course of care.

What Is an Overbite?
An overbite occurs when the upper front teeth significantly overlap the lower front teeth when the mouth is closed. It is sometimes referred to as a “deep bite.” The degree of vertical overlap varies between individuals — a small amount of overlap is considered normal and is present in most people, but when the upper teeth cover a substantial portion of the lower teeth, it may be described as an excessive or deep overbite.
Mild Overbite
A mild overbite may not cause noticeable symptoms or functional concerns. Many people have a slight vertical overlap of the front teeth that does not require treatment. Regular dental examinations can help monitor bite alignment over time and identify any changes that may develop.
Moderate to Pronounced
A more pronounced overbite may influence bite mechanics and tooth wear. When the upper teeth cover a significant portion of the lower teeth, it may alter how forces are distributed during chewing, potentially contributing to uneven wear patterns or discomfort in some individuals.
Assessment Matters
Professional dental assessment can help evaluate the degree of overbite, determine whether it is affecting oral health or function, and guide decisions about whether monitoring or active management may be appropriate. Each individual’s situation is unique.

Common Causes of an Overbite
An overbite may develop due to a combination of factors rather than a single cause. Understanding the potential contributing factors can help inform decisions about monitoring and care.
1Natural Jaw and Tooth Development
The way the jaw grows and the teeth develop during childhood and adolescence plays a significant role in determining bite alignment. The relative size and position of the upper and lower jaws, along with the eruption pattern of the teeth, can influence whether an overbite develops. These developmental factors are largely determined by genetics and growth patterns.
2Genetic Factors
Genetics can influence jaw size, jaw shape, and tooth position — all of which contribute to bite alignment. If parents or close family members have an overbite or deep bite, there may be an increased likelihood of similar bite characteristics developing. Genetic influences on jaw structure are among the most common factors associated with overbite.
3Childhood Habits
Habits during childhood, such as prolonged thumb sucking, dummy use, or tongue thrusting, may influence how the teeth and jaws develop. These habits can apply sustained pressure on the developing teeth and supporting bone, potentially affecting the position of the front teeth and contributing to increased vertical overlap.
4Tooth Loss Affecting Bite Alignment
When teeth are lost — whether due to decay, gum disease, or injury — the remaining teeth may gradually shift position over time. This movement can alter bite alignment and may contribute to the development or worsening of an overbite. Replacing missing teeth promptly may help preserve bite balance.
5Teeth Grinding or Long-Term Wear
Teeth grinding (bruxism) and long-term tooth wear can gradually alter the shape and height of the teeth, which may influence how the upper and lower teeth meet. As tooth surfaces wear down, the bite may deepen, potentially increasing the degree of vertical overlap over time.
6Changes in Tooth Position Over Time
Even in the absence of tooth loss or grinding, teeth can shift gradually over the years. This natural drift may alter bite alignment, particularly if there are changes in the supporting bone or gum tissues. Regular dental assessments can help monitor these changes and identify any developing concerns.
Multiple factors may contribute to an overbite simultaneously. A professional can help identify which factors may be most relevant and guide appropriate management.
When an Overbite May Need Professional Assessment
A mild overbite may not require treatment, but certain signs may suggest that professional evaluation could be beneficial. Assessment can help determine whether the overbite is affecting oral health, function, or comfort, and guide decisions about care.
The Bite Feels Uncomfortable or Uneven
If you notice that your bite feels unbalanced, awkward, or uncomfortable when chewing, this may indicate that the overbite is affecting how forces are distributed across the teeth. An uneven bite can sometimes contribute to localised discomfort or make certain activities — such as biting into harder foods — less comfortable.
Teeth Show Signs of Excessive Wear
Uneven tooth wear — particularly on the biting edges of the front teeth or the surfaces of the back teeth — may suggest that the bite is placing disproportionate forces on certain areas. Over time, this wear may affect the shape, strength, or appearance of the teeth. A dentist can assess wear patterns during a routine examination.
Jaw Discomfort or Muscle Strain
An overbite may sometimes contribute to jaw muscle strain, fatigue, or discomfort — particularly if the bite position places the jaw in a less than optimal resting position. Some individuals may notice aching in the jaw muscles, around the temples, or near the jaw joints. These symptoms may benefit from professional evaluation.
Speech or Chewing Is Affected
In some cases, a pronounced overbite may influence speech clarity or make chewing less efficient. If you notice changes in how you speak or find that chewing certain foods has become more difficult, a dental assessment can help determine whether the bite alignment may be a contributing factor.
When to Seek Assessment
Professional evaluation may be helpful if you notice any of the following. These signs do not necessarily indicate a serious problem, but timely assessment can support informed decisions about care.
Bite feels unbalanced, uncomfortable, or awkward
Visible or noticeable wear on the biting edges of teeth
Jaw aching, fatigue, or muscle strain
Difficulty chewing certain foods comfortably
Changes in speech clarity or articulation
Front teeth overlapping significantly more than before

Oral Health Effects Linked to Overbite
A pronounced overbite may contribute to a range of oral health effects over time. The extent of these effects varies between individuals and depends on the degree of the overbite and other clinical factors.
Professional dental assessment may help evaluate bite balance and identify whether any of these effects are present. Treatment depends on clinical evaluation and the individual’s specific circumstances.
Potential Effects on Oral Health
When the bite is misaligned, some teeth may bear more force during chewing than others. Over time, this may contribute to uneven wear patterns — particularly on the biting edges of the front teeth or the cusps of the back teeth. Monitoring wear during routine examinations can help identify changes early.
An overbite may alter the distribution of biting forces, meaning that certain teeth experience greater pressure than they would in a well-aligned bite. This may contribute to sensitivity, microfractures, or accelerated wear on the affected teeth. Professional care may help identify contributing factors.
In some cases, an overbite may place the jaw in a position that requires the muscles to work harder during chewing or at rest. This may contribute to jaw muscle fatigue, aching, or tension — particularly around the temples or jaw joints. Assessment can help determine whether bite alignment may be a contributing factor.
Existing dental restorations — such as fillings, crowns, or bonding — may be affected by the forces associated with an overbite. Uneven bite pressure may contribute to wear, chipping, or loosening of restorations over time. Regular dental reviews can help monitor the condition of restorations in the context of bite alignment.
Preventive and Professional Care
Managing an overbite involves monitoring bite alignment, assessing any effects on oral health, and determining whether active treatment may be appropriate. Regular dental care plays an important role in maintaining bite health and identifying changes over time.
Monitoring and Preventive Measures
Regular dental examinations help monitor bite alignment and identify any changes in how the teeth meet over time.
Dentists may assess tooth wear patterns to determine whether the overbite is contributing to uneven forces on certain teeth.
Jaw function assessment can help identify any strain or discomfort associated with the bite position.
Monitoring symptoms — such as jaw aching, difficulty chewing, or changes in tooth wear — may form part of ongoing care.
Professional Treatment Options
Treatment planning for an overbite may involve restorative or orthodontic considerations, depending on the underlying cause and the degree of bite misalignment. Options may include orthodontic treatment to adjust tooth positions, to restore tooth height, or to improve how the teeth meet.
In some cases, may be considered to refine the shape of the biting edges, while may address both bite and aesthetic considerations where appropriate.
Professional evaluation determines the most appropriate care for each individual. Treatment depends on clinical findings and the specific factors contributing to the overbite.
Temporary Measures Before Assessment
If you are experiencing discomfort or concerns related to an overbite, the following general measures may help while professional assessment is arranged. These do not replace professional dental care.
Recommended
Avoid chewing very hard foods if the bite feels uncomfortable or uneven, as this may reduce additional strain on the teeth and jaw.
Maintain regular oral hygiene, including thorough brushing and cleaning between teeth, to support overall dental health.
Be mindful of teeth grinding or jaw clenching habits, particularly during times of stress or during sleep.
Note any changes in symptoms — such as increased jaw aching or new areas of tooth sensitivity — to discuss with your dentist.
Arrange professional dental assessment if symptoms persist, worsen, or if you notice changes in your bite alignment.
Avoid
Do not attempt to adjust your bite or tooth position yourself — bite alignment requires professional assessment and management.
Avoid habitually biting on hard objects such as pens, ice, or fingernails, as this may worsen wear on the teeth.
Do not ignore persistent jaw discomfort or increasing tooth wear — these may benefit from professional evaluation.
Avoid using over-the-counter dental appliances or devices without professional guidance, as poorly fitting devices may cause harm.
Do not delay seeking assessment if symptoms are progressing or affecting your daily comfort or function.
These measures are general guidance only and do not replace professional dental care. If you are concerned about your bite alignment, please contact us to arrange an assessment.
