Closed bites, also known as deep bites or overbites, occur when the upper front teeth excessively overlap the lower front teeth. This dental misalignment can lead to various oral health issues, including tooth wear, jaw pain, and potential gum problems. While traditional braces have long been the standard treatment, modern orthodontics offers alternative solutions. Let’s explore the nature of closed bites and the various treatment options available, including the role of Invisalign in addressing this condition.
Understanding Closed Bites:
A closed bite is characterized by an excessive vertical overlap of the upper front teeth over the lower front teeth when the jaw is closed. This misalignment can range from mild to severe, potentially affecting both dental function and facial aesthetics.
Implications of Closed Bites:
Untreated closed bites can lead to several complications:
– Excessive wear on front teeth, potentially leading to sensitivity and decay
– Increased risk of gum recession, especially behind the upper front teeth
– Jaw pain and temporomandibular joint (TMJ) disorders
– Difficulty in proper biting and chewing
– Impacts on facial profile and self-esteem
Treatment Options for Closed Bites:
1. Traditional Braces:
Still a highly effective method, braces use constant gentle pressure to gradually realign teeth and correct jaw positioning.
2. Invisalign:
For mild to moderate cases, Invisalign offers a less visible alternative. These clear aligners can effectively address closed bites while providing the benefit of being removable.
3. Functional Appliances:
Particularly useful for growing children, these devices can help guide jaw growth and improve alignment.

Closed Bites Cardiff – Frequently Asked Questions
What is a Closed Bite and How Does It Differ from Other Dental Alignment Issues?
A closed bite, also known as a deep bite or overbite, is a dental condition where the upper front teeth excessively overlap the lower front teeth vertically when the jaws are closed. It is a type of malocclusion, which means the teeth are not aligning properly when the mouth is closed.
Understanding Closed Bites
In a healthy dental alignment, the upper front teeth should slightly overlap the lower front teeth. A closed bite occurs when this overlap is excessive.
Types of Closed Bites
There are two primary types of closed bites:
- Dental Closed Bite: Occurs due to misalignment of teeth.
- Skeletal Closed Bite: Results from jaw structure issues.
Differences from Other Dental Alignment Issues
Closed bites are distinct from other common dental alignment issues such as underbites, open bites, and crossbites.
Comparison with Underbites and Open Bites
An underbite is characterised by the lower teeth extending out beyond the upper front teeth, while an open bite occurs when the upper and lower teeth do not touch when the mouth is closed. Closed bites differ as they involve excessive vertical overlap of the front teeth.
Comparison with Crossbites
In a crossbite, some upper teeth sit inside the lower teeth when the mouth is closed. Closed bites, however, involve a vertical misalignment rather than a horizontal one.
Importance of Addressing Closed Bites
Addressing closed bites is crucial for oral health and function. Untreated closed bites can lead to issues like excessive wear on the front teeth, jaw pain, and difficulties in proper biting and chewing.
Benefits of Correcting Closed Bites
Correcting a closed bite can improve the functionality of the bite, enhance oral health, and contribute to a more balanced facial profile and aesthetically pleasing appearance of the teeth.
Closed bites are a specific type of dental alignment issue that can have various impacts on oral health and function. Understanding the nature of closed bites and how they differ from other alignment issues is key to seeking appropriate dental care and treatment.
What are the Common Signs and Symptoms of a Closed Bite?
Recognising the signs and symptoms of a closed bite is crucial for early detection and treatment. A closed bite can present several indicators, ranging from visible misalignment to more subtle symptoms affecting oral health and functionality.
Visible Misalignment of Teeth
One of the most noticeable signs of a closed bite is the excessive vertical overlap of the upper front teeth over the lower front teeth when the mouth is closed.
Appearance of the Smile
In a closed bite, the lower front teeth may be partially or completely hidden behind the upper front teeth when smiling, giving the appearance of a “toothy” smile or a recessed chin.
Functional Symptoms of a Closed Bite
Beyond visible misalignment, a closed bite can lead to functional issues that affect everyday activities like eating and speaking.
Difficulty in Biting and Chewing
Individuals with a closed bite may experience difficulty or discomfort while biting into certain foods, particularly those requiring a clean bite with the front teeth.

Increased Risk of Tooth Wear and Damage
When teeth are misaligned in a closed bite, it can lead to excessive wear and potential damage to the teeth.
Enamel Erosion
The excessive contact between upper and lower front teeth can cause premature wear of the tooth enamel, potentially leading to sensitivity and increased risk of decay.
Gum Recession and Periodontal Issues
A closed bite can put undue pressure on the gums, particularly behind the upper front teeth.
Impact on Gum Health
This pressure can lead to gum recession, exposing tooth roots and potentially causing periodontal problems.
Jaw Pain and TMJ Disorders
The misalignment caused by a closed bite can strain the jaw muscles and joints, leading to discomfort, chronic jaw pain, and even temporomandibular joint disorders (TMJ).
Long-Term Strain on Jaw Muscles
Continued strain from a misaligned bite can lead to conditions such as TMJ disorders, characterised by pain in the jaw joint and surrounding muscles.
Impaired Chewing Efficiency and Digestive Issues
A closed bite can affect the way the jaws move during eating, potentially leading to impaired chewing efficiency.
Chewing and Digestive Issues
Inefficient chewing due to a closed bite can impact digestion, as it’s the first step in the digestive process.
Aesthetic Concerns and Self-Esteem Issues
The visible effects of a closed bite can lead to aesthetic concerns, potentially affecting an individual’s self-esteem and confidence in social situations.
Leaving a closed bite untreated can lead to a range of dental problems, from tooth wear and gum recession to jaw pain and digestive issues. Addressing a closed bite early can help mitigate these risks and promote better oral health and overall well-being.
What Causes a Closed Bite in Children and Adults?
The causes of closed bites in children and adults can vary, involving a mix of genetic and environmental factors. Understanding these causes is essential in addressing and preventing this dental issue.
Genetic Factors
Genetics play a significant role in the development of a closed bite. The size and shape of the jaw and teeth, which are often inherited traits, can predispose individuals to this condition.
Inherited Jaw Structure
An imbalance in the size of the upper and lower jaws, often passed down through families, can lead to a closed bite. This can result in either an overdeveloped upper jaw or an underdeveloped lower jaw.
Dental Development Issues
The way teeth develop and erupt can also contribute to a closed bite. This can be influenced by both genetic and environmental factors.
Tooth Eruption Patterns
Irregular patterns in the eruption of permanent teeth can lead to misalignment and closed bites.
Environmental Factors
Certain environmental factors, particularly in early childhood, can influence the development of a closed bite.
Prolonged Habits in Childhood
Habits like thumb sucking or prolonged pacifier use can affect jaw development and tooth positioning, potentially leading to a closed bite.
Adult-Specific Causes
In adults, other factors may contribute to the development or worsening of a closed bite.
Tooth Loss and Shifting
Loss of back teeth without timely replacement can cause shifting in the remaining teeth, potentially leading to a closed bite situation over time.
Wear and Tear of Teeth
Natural wear of teeth over time, especially in individuals who grind their teeth, can exacerbate a closed bite.
Understanding the causes of closed bites in children and adults, ranging from genetic factors to specific habits and dental issues, is key to effective prevention and treatment. Early intervention and addressing contributing factors are crucial in managing this dental misalignment.
At What Age Should a Closed Bite Be Treated?
The appropriate age for treating a closed bite largely depends on the severity of the condition and the individual’s growth and development. However, earlier intervention is generally recommended for the most effective treatment.
Early Intervention in Children
Identifying and treating a closed bite in childhood, particularly during the early growth stages, can be more effective. The jaw and teeth are more adaptable during these years, allowing for potentially simpler and more effective treatments.
Treatment During Growth Spurts
For many children, beginning treatment for a closed bite during their growth spurts (usually around the age of 7-10) can be advantageous. This coincides with a period of rapid growth, which can aid in correcting the misalignment.
Adolescents and Closed Bite Treatment
During adolescence, while the jaw is still growing, treatment for a closed bite can also be effective. Braces or other orthodontic appliances are commonly used during this stage.
Benefits of Adolescent Treatment
Treating a closed bite during adolescence can prevent further complications and ensure proper alignment as the permanent teeth fully emerge and the jaw completes its growth.
Treatment for Adults
Adults can also undergo closed bite treatment, although it may be more complex and time-consuming due to the maturity of the jawbone and teeth.
Approaches for Adult Treatment
In adults, treatment may involve a combination of orthodontic appliances and, in some cases, surgical procedures to correct the alignment.
There is no one-size-fits-all answer for the best age to treat a closed bite, as it depends on individual factors such as the severity of the condition and the stage of jaw development. Early assessment and intervention, particularly in childhood and adolescence, are typically more effective for easier and more successful treatment outcomes.
Are There Different Types of Closed Bites?
Yes, there are different types of closed bites, each affecting the teeth and jaw alignment in distinct ways. Understanding these types is important for accurate diagnosis and effective treatment.
Dental Closed Bite
A dental closed bite occurs when the misalignment is primarily due to the positioning of the teeth rather than jaw structure issues.
Characteristics of Dental Closed Bites
In this type, the teeth themselves are misaligned, causing the upper front teeth to excessively overlap the lower front teeth.
Skeletal Closed Bite
A skeletal closed bite involves issues with the jaw structure itself, typically resulting from differences in growth between the upper and lower jaws.
Impact on Facial Profile
Skeletal closed bites often affect the overall facial profile, potentially leading to a recessed chin appearance.
Deep Bite
A deep bite is a severe form of closed bite where the upper front teeth completely cover the lower front teeth when biting.
Implications of Deep Bites
Deep bites can lead to more significant issues with tooth wear and potential gum damage.
Incomplete Closed Bite
An incomplete closed bite is where the overlap is present but less severe than in a deep bite.
Varying Degrees of Severity
The severity of incomplete closed bites can vary, affecting treatment approaches and duration.
Understanding the different types of closed bites is crucial for devising an appropriate treatment plan. Each type of closed bite has unique characteristics and implications for oral health, requiring tailored approaches to correction.
How is a Closed Bite Diagnosed by a Dentist or Orthodontist?
A closed bite is diagnosed through a combination of clinical examination, dental history, and specialised imaging by a dentist or orthodontist. Accurate diagnosis is key to determining the most effective treatment plan.
Clinical Examination
The first step in diagnosing a closed bite involves a thorough examination of the teeth and jaw alignment. The dentist or orthodontist will check how the upper and lower teeth align when the mouth is closed.
Assessment of Bite Alignment
The professional will assess the bite by asking the patient to bite down normally. This helps in identifying the degree of vertical overlap between the upper and lower front teeth.
Dental and Medical History
A review of the patient’s dental and medical history can provide insights into potential causes of a closed bite, such as genetic factors or childhood habits.
Understanding Developmental Factors
Discussing the patient’s dental development, including the emergence and loss of baby teeth, can offer important clues about the onset of the closed bite.
Imaging Studies
Detailed imaging studies are crucial for a comprehensive assessment of a closed bite.
Dental X-Rays
X-rays, including panoramic or cephalometric films, allow the dentist or orthodontist to view the alignment of teeth and jawbone, helping to distinguish between dental and skeletal closed bites.
3D Imaging
In some cases, advanced imaging techniques like 3D cone-beam computed tomography (CBCT) may be used for a more detailed analysis of the jaw structure.
Impression and Model Analysis
Taking impressions of the teeth to create plaster or digital models can help in assessing the bite and planning orthodontic treatment.
Evaluating Teeth Position
Models created from impressions provide a 3D representation of the teeth alignment, allowing for detailed examination and treatment planning.
The diagnosis of a closed bite by a dentist or orthodontist involves a systematic approach, including clinical examination, review of dental history, and specialised imaging. This comprehensive evaluation is essential to identify the type and severity of the closed bite and guide effective treatment.
What are the Treatment Options Available for Correcting a Closed Bite?
Several treatment options are available for correcting a closed bite, depending on its type and severity. These treatments aim to realign the teeth and jaw for improved function and aesthetics.
Orthodontic Braces
Traditional braces are a common and effective treatment for correcting closed bites. They apply continuous pressure to the teeth to gradually move them into the correct position.
Use of Braces in Closed Bite Correction
Braces can be used to correct both dental and mild skeletal closed bites by realigning the teeth and adjusting jaw position.
Clear Aligners
Clear aligners, such as Invisalign, offer a less noticeable alternative to traditional braces. They are custom-made and work by gradually moving the teeth into the desired position.
Effectiveness for Mild to Moderate Closed Bites
Clear aligners are generally more suited for mild to moderate closed bites and offer the convenience of being removable.
Bite Plates or Functional Appliances
For growing children with skeletal closed bites, bite plates or functional appliances can be used to guide jaw growth and improve alignment.
Application in Children and Adolescents
These appliances are most effective in children and adolescents while the jaw is still growing.
Surgical Options
In adults with severe skeletal closed bites, where the jaw has stopped growing, orthognathic (jaw) surgery may be necessary to correct the alignment.
Combination with Orthodontic Treatment
Orthognathic surgery is often combined with orthodontic treatment for comprehensive correction of the closed bite.
Tooth Reshaping and Bonding
In some mild cases, tooth reshaping or dental bonding may be used to improve the appearance and function of teeth affected by a closed bite.
Conservative Approach
This approach is typically used for minor corrections or as part of a comprehensive treatment plan.
Interproximal Reduction
In certain cases, interproximal reduction (slight reshaping of tooth enamel) may be used in conjunction with orthodontic treatment to create space for proper alignment.
Precision Technique
This technique requires careful planning and execution by an experienced orthodontist.
The treatment options for correcting a closed bite vary based on the individual case and can range from orthodontic braces and clear aligners to functional appliances and surgery. A dentist or orthodontist can recommend the most suitable treatment based on the type and severity of the closed bite.
How Long Does Closed Bite Treatment Typically Take?
The duration of closed bite treatment can vary significantly depending on the severity of the condition, the chosen treatment method, and the individual’s response to treatment. Understanding these factors can help set realistic expectations for the treatment timeline.
Factors Influencing Treatment Duration
Several factors contribute to how long it takes to correct a closed bite, each playing a role in the overall treatment timeline.
Severity of the Closed Bite
The degree of misalignment significantly influences treatment duration. Mild cases may be corrected more quickly, while severe cases often require longer treatment periods.
Age and Growth
Age and growth stage are critical factors. Children and adolescents may respond more quickly to treatment due to their growing jaws and teeth, potentially shortening the treatment duration.
Typical Treatment Timelines
While treatment duration varies, there are general timelines for common closed bite treatments.
Braces and Clear Aligners
Orthodontic treatment with braces or clear aligners for a closed bite can typically take anywhere from 18 months to 3 years. Regular adjustments and monitoring are necessary throughout this period.
Functional Appliances
Use of functional appliances in children can take 6 to 18 months, depending on the individual case and compliance.
Impact of Surgical Interventions
In cases where surgery is involved, such as in adult skeletal closed bites, the treatment process can be extended. This includes pre-surgical preparation, the surgical procedure itself, and post-surgical orthodontic treatment.
Post-Surgical Orthodontics
After surgery, orthodontic treatment may continue for several months to a year to fine-tune the alignment of the teeth and jaw.
Importance of Compliance
Patient compliance with treatment instructions, such as wearing appliances as directed and attending regular appointments, is crucial in achieving the desired results within the estimated timeframe.
The duration of closed bite treatment varies based on individual factors, severity of the condition, and treatment method. A comprehensive evaluation by a dental professional can provide a more accurate timeline tailored to the individual’s specific needs.
