Millions of people across the world deal with dental alignment issues, and overbite teeth are one of the most common. While some overbites are minor and purely cosmetic, others can cause long-term oral health complications, jaw pain, and self-esteem issues.
In this comprehensive guide, we’ll explore everything you need to know about overbite teeth — from what they are and why they happen, to the most effective ways to fix them. Whether you’re a concerned parent, an adult exploring orthodontic options, or just researching out of curiosity, this post will help you make informed decisions.
What Is an Overbite?
Definition of Overbite Teeth
An overbite is a type of malocclusion, or dental misalignment, where the upper front teeth excessively overlap the lower front teeth when the jaws are closed. This condition is also referred to as a “deep bite” when the overlap is especially significant.
There are two ways to measure overbites:
- Vertical overbite: The amount the upper teeth cover the lower teeth vertically.
- Horizontal overbite (overjet): How far the upper teeth protrude in front of the lower teeth.
A normal overbite is generally considered to be about 2-4 mm, or roughly 20-30% vertical overlap. Anything more than that is considered excessive and may require treatment.
“A small overbite is normal and even desirable for healthy chewing and facial aesthetics. It only becomes a problem when the overlap is too large or causes functional issues.” — Dr. Linda Park, Orthodontist
Is an Overbite Bad?
Not all overbites are harmful, but moderate to severe overbite teeth can lead to long-term problems if left untreated. Common complications include:
- Jaw pain and TMJ (temporomandibular joint) issues
- Difficulty chewing or speaking clearly
- Uneven tooth wear and damage
- Increased risk of tooth decay and gum disease
- Low self-confidence due to appearance
While cosmetic concerns often motivate people to seek overbite correction, the underlying health issues make it even more important to take action early.
FAQs (Answer Engine Optimization)
What is the normal range of an overbite?
A normal overbite typically ranges between 2mm to 4mm, or about 20–30% overlap of the lower front teeth.
Is an overbite a serious condition?
Mild overbites are common and not necessarily serious, but severe overbites can lead to jaw pain, worn teeth, and other oral health issues.
How do I know if I have an overbite?
If your upper front teeth cover more than one-third of your lower teeth when biting down, you may have an overbite. A dentist can confirm with an examination and X-rays.
Types of Overbites
Not all overbites are the same. In fact, understanding the type of overbite you or your child has is the first step toward choosing the right treatment. Overbites are generally classified based on their cause and severity.
There are two primary types of overbite teeth:
Skeletal Overbite
A skeletal overbite occurs when the jawbone itself is misaligned. This means the upper jaw (maxilla) extends too far forward or the lower jaw (mandible) is underdeveloped. In some cases, both jaw structures are misaligned.
Causes of Skeletal Overbites:
- Genetic jaw structure abnormalities
- Hereditary factors
- Growth deficiencies during childhood
Treatment Options:
- Orthognathic (jaw) surgery, often combined with braces or aligners
- Early orthopedic intervention in children (e.g., headgear or growth-modifying appliances)
Note: Skeletal overbites cannot be corrected with braces alone if the jaw discrepancy is severe. In these cases, a surgical consultation is necessary.

Dental Overbite
A dental overbite is caused by misalignment of the teeth, not the jawbone. It’s far more common than skeletal overbites and can usually be corrected with orthodontic treatment alone.
Causes of Dental Overbites:
- Prolonged thumb sucking or pacifier use
- Missing or extra teeth
- Crowding or spacing issues
- Poor oral habits or delayed dental care
Treatment Options:
- Braces or clear aligners (like Invisalign)
- Tooth extraction (in severe crowding cases)
- Retainers to maintain results
Authority Resource: Mayo Clinic – Malocclusion of Teeth
Deep Bite vs. Overbite: What’s the Difference?
A deep bite is a severe form of overbite, where the upper front teeth overlap the bottom teeth by more than 4mm — often significantly more. The bottom teeth may even touch the roof of the mouth, leading to gum trauma, enamel wear, and speech problems.
| Type | Description | Typical Treatment |
|---|---|---|
| Normal Overbite | 2–4 mm vertical overlap | Usually no treatment needed |
| Mild Overbite | Slight cosmetic concern | Braces or aligners |
| Deep Bite | >4 mm vertical overlap | Braces, bite correction devices, sometimes surgery |
Resource: Colgate – Deep Bite: What Is It and How Is It Treated?
How to Tell Which Type You Have
Only a qualified orthodontist or dentist can accurately determine the type of overbite through a clinical exam and diagnostic tools like:
- Panoramic X-rays
- Digital impressions or 3D scans
- Cephalometric radiographs (to analyze skeletal structure)
American Association of Orthodontists – Why See an Orthodontist?
FAQs: Types of Overbites
Can you have both skeletal and dental overbites?
Yes, some people have a combined skeletal-dental overbite, which means both the jaw and teeth are misaligned. These cases are more complex and usually require a multi-phase treatment approach.
Is a deep bite more serious than a regular overbite?
Yes, a deep bite can lead to more serious oral health problems, including gum damage, tooth wear, and TMJ disorders.
Can I fix a dental overbite without surgery?
Absolutely. Most dental overbites can be corrected with braces, aligners, or growth modification appliances — especially when treated early.

Causes of Overbite Teeth
Understanding the causes of overbite teeth is crucial for prevention and treatment. Overbites don’t occur overnight — they typically develop over time due to a mix of genetic, behavioral, and anatomical factors. In children, early detection is especially important, as habits and growth patterns can often be corrected before they worsen.
Below are the most common causes of overbite teeth:
1. Genetics and Family History
The most significant contributing factor to an overbite is genetics. Just like eye color or height, jaw size and shape are inherited traits. If one or both parents have an overbite, there’s a strong chance their child may develop one as well.
Inherited traits that may lead to overbite include:
- A small lower jaw (mandibular deficiency)
- A large upper jaw (maxillary excess)
- Disproportionate tooth-to-jaw size
- Crowded or gapped teeth
Source: National Institutes of Health – Genetic Influence on Malocclusion
2. Childhood Oral Habits
Certain behaviors during early childhood can disrupt jaw development and lead to dental overbites. These are often classified as “oral parafunctional habits.”
Common habits that contribute to overbites:
- Thumb sucking
- Prolonged pacifier use
- Tongue thrusting
- Extended bottle feeding (past age 2)
- Nail biting or pencil chewing
These habits exert forward pressure on the upper front teeth, causing them to protrude or tip over the bottom teeth, eventually resulting in an overbite.
Source: American Dental Association – How Childhood Habits Affect Oral Development
3. Jaw Growth Imbalance
In many cases, an overbite is the result of asynchronous growth between the upper and lower jaws during childhood. For example, if the lower jaw develops slower than the upper jaw, the upper teeth will naturally protrude forward.
This is often observed during puberty, a period of rapid bone growth. Without orthodontic intervention, the mismatch can worsen into adulthood.
Risk signs include:
- Weak chin or receding jaw
- Forward-protruding upper teeth
- Facial asymmetry or bite difficulty
4. Tooth Crowding or Misalignment
Dental crowding happens when there’s not enough room in the mouth for teeth to erupt properly. This can cause the upper teeth to push forward, leading to a dental overbite.
Similarly, missing teeth (especially molars) can change the bite pattern, forcing the remaining teeth to shift into unnatural positions. Over time, this imbalance causes an overbite.
Key contributing factors:
- Premature tooth loss
- Impacted teeth
- Poor dental hygiene leading to decay or extractions
5. TMJ Disorders and Jaw Muscle Imbalance
The temporomandibular joint (TMJ) plays a crucial role in jaw movement and alignment. Disorders that affect the joint or the surrounding muscles can cause the lower jaw to rest farther back than normal, contributing to the development or worsening of an overbite.
Symptoms often include:
- Clicking or popping sounds in the jaw
- Difficulty opening or closing the mouth fully
- Headaches or jaw pain, especially when chewing
National Institute of Dental and Craniofacial Research – TMJ Disorders
FAQs: Causes of Overbite Teeth
Can overbite be caused by thumb sucking?
Yes. Prolonged thumb sucking during early childhood can push the upper front teeth forward and contribute to dental overbite development.
Is overbite hereditary?
Absolutely. Genetics play a significant role in jaw size and teeth alignment. Many overbite cases are inherited.
Can wisdom teeth cause overbite?
While not a direct cause, impacted or crowded wisdom teeth can worsen existing misalignment, including overbites, by pushing other teeth forward.
Does tongue thrusting cause overbite?
Yes. Tongue thrusting applies constant forward pressure to the upper front teeth, encouraging them to move outward over time.
Signs and Symptoms of Overbite
Recognizing the signs of overbite teeth early can help prevent serious oral health problems later in life. While some overbites are noticeable at a glance, others may be subtle and go undetected until complications arise.
Here’s what to look for — whether in yourself, a child, or a patient.
1. Visible Teeth Overlap
One of the most apparent signs of an overbite is when the upper front teeth extend too far down over the lower front teeth when the mouth is closed. In a normal bite, the upper teeth should only cover about 20–30% of the lower teeth.
If you notice that more than half of the bottom teeth are hidden when you bite down, it’s likely a sign of moderate to severe overbite.
Mayo Clinic – Malocclusion: Signs and Symptoms
2. Jaw Pain or Clicking
An untreated overbite can cause misalignment of the jaw joint (TMJ). This can lead to muscle tension, improper bite force, and inflammation in the temporomandibular joint.
Common jaw-related symptoms include:
- Clicking or popping sounds when opening or closing the mouth
- Soreness or stiffness in the jaw
- Pain that radiates to the neck or temples
- Trouble opening the mouth fully
National Institutes of Health – TMJ Disorders
3. Difficulty Chewing or Speaking
When teeth aren’t properly aligned due to an overbite, basic functions like chewing, biting, and speaking can become difficult or even painful.
Signs include:
- Biting into the roof of the mouth
- Pain when eating hard or chewy foods
- Difficulty pronouncing certain sounds or words (especially “s” or “f” sounds)
Cleveland Clinic – Malocclusion and Speech Issues
4. Chronic Headaches or Earaches
Severe overbites may put excess pressure on the facial muscles and jaw joints, often leading to headaches or pain that mimics earaches. This happens when the jaw is misaligned and places strain on nearby nerves and tissues.
You might also notice:
- Tension or pain in the temples
- Dull ache around the ears, not related to infection
- Jaw fatigue or tightness, especially after talking or eating
American Dental Association – Oral Health and Headaches
5. Uneven Tooth Wear or Damage
Overbite teeth can cause uneven wear as the upper and lower teeth make abnormal contact. Over time, this may result in:
- Flattened or chipped teeth
- Worn-down enamel (increasing sensitivity)
- Increased risk of cavities and tooth fractures
- Gum recession from improper bite pressure
Dentists often detect overbites during routine exams by noticing these signs of wear.

6. Self-Esteem and Confidence Issues
Though often overlooked, the psychological effects of visible dental problems like overbite are real. People with significant overbites may feel self-conscious about their smile or avoid social situations entirely.
Signs include:
- Covering the mouth when speaking or laughing
- Smiling with lips closed
- Avoiding photos or public speaking

FAQs: Signs of Overbite Teeth
How do I know if my overbite is severe?
If your upper teeth cover more than 4 mm of your lower front teeth or if you’re experiencing jaw pain, speech issues, or enamel wear, you may have a severe overbite.
Can an overbite cause jaw pain?
Yes. A misaligned bite puts pressure on your jaw joints and muscles, which can cause TMJ-related symptoms like clicking, soreness, and headaches.
Can overbite cause speech problems?
Absolutely. Overbites can interfere with tongue placement, leading to speech articulation issues, especially for sounds like “s,” “z,” “th,” and “f.”
How to Diagnose an Overbite
Diagnosing overbite teeth accurately is essential for developing an effective treatment plan. While some mild overbites are visible without professional help, a formal diagnosis from a dental or orthodontic professional is necessary to assess the severity and underlying causes.
1. Clinical Examination by a Dentist or Orthodontist
The first step in diagnosing an overbite is a thorough clinical examination. A dentist or orthodontist will visually inspect the alignment of the teeth and jaws, noting the extent of upper-to-lower teeth overlap.
During this exam, the professional will check for:
- The vertical overlap of the upper front teeth over the lower front teeth
- Jaw alignment and symmetry
- Bite function during chewing and speaking
- Signs of wear or damage to teeth
American Association of Orthodontists – Getting an Orthodontic Diagnosis
2. Dental X-rays
X-rays provide a detailed view of the teeth, jawbone, and roots, helping the orthodontist identify:
- Jawbone structure and positioning
- Tooth roots and any impacted teeth
- Growth abnormalities in children
- Degree of skeletal vs. dental overbite
Common types of X-rays used include panoramic X-rays and cephalometric radiographs.
These images help differentiate between skeletal overbites, caused by jaw discrepancies, and dental overbites caused by tooth misalignment.
3. Digital Impressions and 3D Scans
Modern orthodontics often uses digital impressions and 3D intraoral scans instead of traditional molds. These scans provide precise models of the teeth and bite for more accurate diagnosis and treatment planning.
Advantages include:
- Faster and more comfortable for patients
- Highly accurate digital records
- Easy to simulate treatment outcomes
Journal of Dental Research – Digital Impressions vs. Traditional Molds
4. Bite Analysis
Orthodontists may perform a bite analysis to evaluate how the teeth come together during function. This includes assessing:
- How the upper and lower teeth contact when biting
- Any abnormal pressure points or premature contacts
- Jaw movement patterns
This step helps identify functional issues caused by an overbite that may not be apparent in static images.
5. Facial and Jaw Measurements
For skeletal overbites, measurements of the face and jaw are critical. Orthodontists measure:
- Jaw length and position relative to the skull
- Chin projection
- Facial symmetry
These measurements help determine if orthodontic treatment alone will suffice or if orthognathic surgery is necessary.

FAQs: Diagnosing Overbite Teeth
Can I diagnose an overbite myself?
You can look for obvious signs like upper teeth covering much of the lower teeth, but only a professional can accurately diagnose the severity and type of overbite.
What tests are used to diagnose overbite?
Dentists use visual exams, dental X-rays, 3D scans, bite analysis, and jaw measurements to diagnose overbite.
How long does the diagnosis process take?
A typical diagnosis appointment takes between 30 minutes to 1 hour, depending on the number of tests and scans required.
Treatment Options for Overbite Teeth
Correcting overbite teeth is essential not only for aesthetics but also for oral health, function, and preventing long-term damage. Treatment options vary widely depending on the type, severity, and cause of the overbite, as well as the patient’s age and overall dental health.
1. Orthodontic Braces
Braces are the most common and effective treatment for dental overbites. They work by gradually shifting teeth into proper alignment, reducing the vertical overlap between upper and lower teeth.
- Traditional metal braces: Durable and effective for all overbite severities.
- Ceramic braces: Less noticeable, using clear or tooth-colored brackets.
- Lingual braces: Placed behind the teeth for an invisible look.
- Clear aligners (e.g., Invisalign): Removable and nearly invisible, ideal for mild to moderate overbites.
Treatment duration typically ranges from 12 to 24 months depending on complexity.
American Association of Orthodontists – Braces and Aligners
2. Orthopedic Appliances
For children and adolescents still growing, orthopedic appliances can guide jaw growth to correct skeletal overbites without surgery.
Common devices include:
- Headgear: Applies pressure to the upper jaw to control growth.
- Functional appliances: Such as the Herbst appliance, which encourages lower jaw growth.
- Palatal expanders: Widen the upper jaw to improve bite alignment.
Early intervention often leads to better outcomes and shorter treatment times.
Cleveland Clinic – Orthodontic Appliances
3. Tooth Extraction
In cases of severe crowding contributing to a dental overbite, removing one or more teeth may be necessary to create space for proper alignment.
- Extraction is typically followed by braces or aligners to reposition remaining teeth.
- Commonly extracted teeth include premolars.
This approach helps avoid worsening the overbite and allows for better bite correction.
Mayo Clinic – Tooth Extraction and Orthodontics
4. Orthognathic (Jaw) Surgery
For severe skeletal overbites caused by jaw discrepancies, orthodontic treatment alone is often insufficient.
- Surgery repositions the upper jaw, lower jaw, or both to achieve proper bite alignment.
- Typically combined with pre- and post-surgical orthodontics.
- Surgery improves function, appearance, and long-term oral health.
This option is usually reserved for adults or late teens whose jaw growth is complete.
American Association of Oral and Maxillofacial Surgeons – Corrective Jaw Surgery
5. Retainers and Post-Treatment Care
After active treatment, retainers are essential to maintain corrected bite and teeth position.
- Fixed or removable retainers prevent teeth from shifting back.
- Wearing retainers as prescribed ensures long-term success.
- Regular dental check-ups help monitor bite stability.
6. Cosmetic Treatments
For mild overbites with mostly aesthetic concerns, cosmetic options may be considered:
- Veneers or bonding to reshape teeth
- Tooth contouring to improve appearance
Note: These do not correct underlying bite issues and are often combined with orthodontic treatments.
Summary Table: Treatment Options
| Treatment Type | Best For | Typical Duration | Notes |
|---|---|---|---|
| Braces (metal/ceramic) | Dental overbites | 12–24 months | Most common treatment |
| Clear Aligners | Mild to moderate overbites | 6–18 months | Removable, discreet |
| Orthopedic Appliances | Growing children (skeletal) | Varies with growth stage | Early intervention recommended |
| Tooth Extraction | Severe crowding | During orthodontics | Creates space for alignment |
| Orthognathic Surgery | Severe skeletal overbites | Surgical recovery + ortho | For jaw repositioning |
| Cosmetic Treatments | Mild aesthetic cases | Few dental visits | Not a functional correction |
FAQs: Overbite Treatment
Can adults fix an overbite?
Yes, adults can successfully correct overbites with braces, aligners, or surgery, though treatment may take longer than for children.
Is jaw surgery painful?
Surgery is performed under anesthesia. Post-operative discomfort is manageable with medication and usually resolves within weeks.
How long does overbite treatment take?
Treatment length depends on severity but generally ranges from 6 months to 2 years.
Preventing Overbite Teeth
Preventing an overbite is often easier than correcting one later. While genetics can play a role, many causes of overbite are related to habits and developmental factors that can be managed early in life. Understanding prevention strategies is key to promoting healthy bite alignment and reducing the risk of dental complications.
1. Early Dental Checkups
Regular dental visits starting in childhood allow dentists to monitor the development of teeth and jaws. Early detection of bite problems lets parents and dentists intervene promptly.
- The American Academy of Pediatric Dentistry recommends a first dental visit by age 1.
- Orthodontic evaluation by age 7 is advised to catch and address bite issues early.
American Academy of Pediatric Dentistry – Early Orthodontic Screening
2. Avoid Prolonged Thumb Sucking and Pacifier Use
Prolonged thumb sucking or pacifier use beyond age 3 can push the upper teeth forward, contributing to the development of an overbite.
- Encourage children to stop habits by age 3.
- Use positive reinforcement and habit-breaking tools if necessary.
Mayo Clinic – Thumb Sucking and Dental Health
3. Promote Proper Tongue and Oral Posture
Incorrect tongue posture, such as resting the tongue against or between the teeth, can exert pressure that worsens overbite.
- Teach children to keep the tongue resting on the roof of the mouth.
- Encourage closed lips and nasal breathing rather than mouth breathing.
American Orthodontic Society – Tongue Posture and Malocclusion
4. Treat Early Dental Issues Promptly
Dental problems like cavities, premature tooth loss, or prolonged bottle feeding can influence bite development.
- Address cavities early.
- Prevent early loss of baby teeth which maintain space for permanent teeth.
- Avoid putting infants to bed with bottles to reduce decay risk.
Centers for Disease Control and Prevention – Prevent Tooth Decay
5. Monitor and Manage Jaw Growth
In children, monitoring jaw growth and development with the help of orthodontists can identify skeletal issues early.
- Use orthopedic appliances if necessary to guide jaw development.
- Early interventions can reduce the need for surgery later.
National Institute of Dental and Craniofacial Research – Jaw Growth
6. Encourage Healthy Eating Habits
Proper nutrition supports healthy bone and teeth development.
- Ensure adequate calcium, vitamin D, and phosphorus intake.
- Avoid excessive sugary foods that cause decay and early tooth loss.
FAQs: Preventing Overbite Teeth
At what age can an overbite be prevented?
Interventions are most effective in early childhood, ideally before age 7, during jaw and tooth development.
Can bad habits cause an overbite?
Yes. Thumb sucking, prolonged pacifier use, and tongue thrusting are common behavioral causes of overbite.
How often should children visit the dentist to monitor bite development?
Children should see a dentist every six months, with an orthodontic evaluation by age 7.
Frequently Asked Questions (FAQs) About Overbite Teeth
What is considered a normal overbite?
A normal overbite means the upper front teeth cover about 20-30% of the lower front teeth when biting down. Anything significantly beyond that is considered a malocclusion or deep overbite.
Can overbite teeth cause health problems?
Yes. Untreated overbites can lead to jaw pain, tooth wear, speech difficulties, and even headaches due to jaw misalignment.
Is overbite hereditary?
Genetics can influence jaw size and teeth alignment, so overbites often run in families. However, environmental factors and habits also play a large role.
How long does overbite treatment take?
Treatment usually lasts between 6 months to 2 years depending on severity and method. Early treatment can be quicker and more effective.
Can adults fix an overbite without surgery?
Many adults correct mild to moderate overbites with braces or clear aligners. Severe skeletal overbites might require jaw surgery for best results.
Are there risks if I leave an overbite untreated?
Yes. Over time, untreated overbites can cause tooth damage, gum recession, TMJ disorders, and affect overall oral health.
Conclusion: Understanding and Managing Overbite Teeth
An overbite is more than just a cosmetic concern — it can impact oral health, function, and quality of life. Recognizing the signs and symptoms of overbite teeth early allows for timely intervention that can prevent long-term complications.
Whether through orthodontic braces, orthopedic appliances, or surgery for severe cases, effective treatments are available for all ages. Prevention strategies, especially in children, can minimize the risk of developing significant overbites.
Regular dental checkups, healthy habits, and professional guidance remain the foundation of maintaining a healthy bite and confident smile.
If you suspect you or a loved one has an overbite, consult with an orthodontist or dentist for a proper diagnosis and personalized treatment plan.
