Overbite vs. Underbite: When Should You See an Orthodontist in Lexington SC?

Your Path to a Perfect Smile: Navigating the Orthodontic Journey at Whitehead Orthodontics.

Have you ever looked at your smile and wondered whether your upper and lower teeth are supposed to fit together differently? Maybe your upper front teeth seem to cover too much of your lower teeth, or your lower jaw appears to extend farther forward than your upper jaw.

These concerns may be signs of an overbite or underbite, two common orthodontic conditions that affect how your teeth and jaws come together.

While many patients first notice these problems because of how their smile looks, bite alignment can also affect chewing, tooth wear, and overall oral function.

At Whitehead Orthodontics in Lexington, SC, Dr. Whitehead provides personalized orthodontic evaluations and treatment options for children, teenagers, and adults experiencing bite alignment concerns.

Understanding the difference between an overbite and an underbite is the first step toward determining whether orthodontic treatment may be beneficial.

What Is an Overbite?

An overbite refers to the vertical overlap between the upper and lower front teeth.

A small amount of overlap is normal. However, when the upper front teeth cover an excessive portion of the lower front teeth, the condition is commonly called a deep bite.

Some patients also use the term overbite to describe upper front teeth that protrude too far forward. Orthodontists distinguish this horizontal relationship as overjet.

An orthodontic evaluation can identify the exact problem and determine whether treatment is needed.

Common Signs of an Excessive Overbite

Signs may include:

Upper front teeth covering most of the lower front teeth
Lower teeth appearing unusually short when smiling
Excessive wear on certain teeth
Lower front teeth contacting the palate or gum tissue
Difficulty achieving a comfortable bite
Concerns about smile appearance

Not every overbite causes symptoms, and not every patient requires treatment.

However, significant bite discrepancies deserve professional evaluation.

What Is an Underbite?

An underbite occurs when the lower front teeth sit in front of the upper front teeth when the mouth is closed.

This is sometimes described as a reverse bite relationship.

Underbites can develop because of tooth positioning, differences in jaw growth, or a combination of both.

Some cases involve primarily dental alignment, while others involve the underlying relationship between the upper and lower jaws.

Common Signs of an Underbite

Patients may notice:

Lower front teeth extending ahead of upper front teeth
A prominent lower jaw appearance
Difficulty biting into certain foods
Uneven tooth wear
A shifting jaw when closing the mouth
Speech or chewing difficulties in some cases

The severity of an underbite can vary considerably.

Some patients have a relatively mild tooth-positioning problem, while others have a more significant skeletal discrepancy.

Overbite vs. Underbite: What’s the Difference?

Although both conditions involve bite alignment, they describe different relationships between the upper and lower teeth.

Overbite: The upper front teeth vertically overlap the lower front teeth. An excessive overlap is commonly called a deep bite.

Underbite: The lower front teeth extend ahead of the upper front teeth.

Both conditions fall under the broader category of malocclusion, a term orthodontists use to describe teeth or jaws that do not align properly.

The appropriate treatment depends on the specific diagnosis rather than simply whether the patient has an overbite or underbite.

What Causes Overbites and Underbites?

Bite problems can develop for several reasons.

Genetics

Jaw size, jaw position, and tooth alignment are influenced by genetics.

Some individuals inherit differences in jaw growth that contribute to an overbite or underbite.

Childhood Oral Habits

Prolonged thumb sucking or other oral habits can influence tooth position and bite development in some children.

The effects depend on the intensity, frequency, and duration of the habit.

Differences in Jaw Growth

When the upper and lower jaws grow at different rates or in different directions, bite discrepancies may develop.

This is particularly important when evaluating growing children.

Tooth Position and Crowding

Sometimes the underlying jaw relationship is relatively normal, but the teeth are positioned in ways that create an improper bite.

Crowding, spacing, and tooth eruption patterns can all influence bite alignment.

Previous Dental Changes

Tooth loss, dental wear, or shifting teeth may alter the bite over time.

An orthodontist evaluates these factors before recommending treatment.

Can an Overbite or Underbite Affect Oral Health?

Bite problems are not always purely cosmetic.

Depending on their severity, they may contribute to functional or dental concerns.

Uneven Tooth Wear

When teeth contact one another improperly, certain teeth may experience excessive wear.

Over time, this can affect tooth structure.

Difficulty Chewing

Some patients with significant bite discrepancies have trouble biting into or chewing certain foods comfortably.

Gum or Soft Tissue Irritation

In severe deep-bite cases, lower teeth may contact the tissues behind the upper front teeth.

Smile Confidence

Patients may feel self-conscious about their bite or facial appearance.

Correcting a bite discrepancy can improve smile aesthetics and confidence.

It’s important to recognize that not every bite problem causes these complications. A professional evaluation helps determine whether treatment is recommended.

How Do Orthodontists Correct an Overbite?

Overbite treatment depends on the severity of the condition, the patient’s age, and whether the problem involves teeth, jaws, or both.

Traditional Braces

Braces are frequently used to correct excessive overbites.

Brackets and wires allow the orthodontist to control tooth movement and improve how the upper and lower teeth fit together.

Additional orthodontic appliances or elastics may be recommended depending on the case.

Invisalign Clear Aligners

Invisalign can correct certain overbite problems using a series of custom-made clear aligners.

For appropriate patients, clear aligners may provide a discreet alternative to traditional braces.

Some cases require additional features or elastics to help achieve the desired bite correction.

Growth-Related Orthodontic Treatment

For children and teenagers who are still growing, certain orthodontic appliances may help manage developing bite problems.

Treatment recommendations depend on the child’s stage of growth and individual needs.

How Do Orthodontists Correct an Underbite?

Underbite treatment can be more complex because the condition may involve differences in jaw structure.

Braces

Braces may correct certain underbites caused primarily by tooth positioning.

They can also be used as part of a more comprehensive treatment plan.

Clear Aligners

Some mild dental underbites may be treated with Invisalign or other clear aligner systems.

However, clear aligners are not appropriate for every underbite, particularly when substantial skeletal differences are present.

Early Orthodontic Intervention

For certain growing children, early orthodontic treatment may help address developing underbites.

Because jaw growth plays an important role, the timing of treatment can be especially significant.

Surgical Orthodontic Treatment

Severe skeletal underbites in adults may require a combination of orthodontic treatment and corrective jaw surgery to achieve comprehensive correction.

When necessary, an orthodontist can coordinate care with an oral and maxillofacial surgeon.

Not every patient with an underbite requires surgery.

A thorough evaluation is essential to determine the appropriate approach.

Can Invisalign Fix an Overbite or Underbite?

Many patients are interested in correcting bite problems without traditional braces.

Invisalign may be effective for certain bite discrepancies, depending on their complexity.

Clear aligners can be used to reposition teeth and improve selected bite relationships.

However, the success of treatment depends on factors such as:

Severity of the bite problem
Tooth movement requirements
Jaw relationships
Patient age
Consistent aligner wear
Need for additional orthodontic appliances

At Whitehead Orthodontics, Dr. Whitehead evaluates these factors before recommending Invisalign, Spark Aligners, braces, or another appropriate treatment option.

The goal is to select the treatment most likely to provide a healthy, stable result.

When Should Children Be Evaluated for Bite Problems?

The American Association of Orthodontists recommends that children receive their first orthodontic evaluation no later than age seven.

This is particularly important when parents notice an underbite, crossbite, or other developing jaw alignment concern.

An early evaluation allows an orthodontist to assess how the teeth and jaws are developing.

Some children benefit from early treatment, while others are best served through periodic monitoring.

Early evaluation does not automatically mean early braces.

Instead, it provides an opportunity to identify concerns and determine the most appropriate timing for care.

Can Adults Correct an Overbite or Underbite?

Yes. Many adults successfully undergo orthodontic treatment to improve bite alignment.

Adult treatment options may include:

Traditional metal braces
Ceramic braces
Invisalign
Spark Aligners
Other orthodontic appliances
Coordinated surgical treatment for selected severe skeletal cases

Although adults no longer have the same jaw growth potential as children, tooth movement can still produce meaningful improvements.

The treatment approach depends on the nature and severity of the bite discrepancy.

How Long Does Bite Correction Take?

Treatment time varies considerably.

Some relatively straightforward dental bite problems may be corrected within a typical comprehensive orthodontic treatment timeline, while more complex cases may require additional time.

Factors influencing treatment duration include:

Type and severity of malocclusion
Age and growth status
Treatment method
Need for additional appliances
Patient cooperation
Individual response to treatment

During your consultation, Dr. Whitehead can explain your diagnosis and provide an estimated treatment timeline.

Frequently Asked Questions About Overbites and Underbites

Is a small overbite normal?

Yes. Some vertical overlap between the upper and lower front teeth is normal. Treatment may be recommended when the overlap is excessive or causes functional, dental, or aesthetic concerns.

Can an underbite get worse with age?

An underbite may become more pronounced during childhood and adolescence as the jaws grow. Changes vary by individual, making early evaluation especially important when an underbite is suspected.

Do all overbites require braces?

No. Mild overbites may fall within a normal range and require no treatment. When correction is needed, braces or clear aligners may be appropriate depending on the case.

Can an underbite be fixed without surgery?

Many dental underbites and some developing skeletal underbites can be treated without surgery. Severe skeletal discrepancies in adults may require surgical correction for an optimal result.

How much does overbite treatment cost in Lexington SC?

The cost depends on the complexity of the bite problem, recommended treatment, expected duration, and insurance benefits. A personalized orthodontic consultation provides the most accurate estimate.
