updated on December 12, 2025

Are you wondering about the differences between overbite vs underbite in Drexel Hill, PA? An overbite occurs when the upper front teeth significantly overlap the lower front teeth, while an underbite is when the lower teeth extend past the upper teeth. Both conditions can impact not only the appearance of your smile but also your oral health. These bite alignment issues are common and can affect your teeth, jaw structure, and even your confidence.

This guide will help you understand their causes, treatments, and how Carpinello Orthodontics provides expert orthodontic care.

What Are Overbites and Underbites?

These bite problems are more than just a cosmetic concern. They can affect how you chew, speak, and even the health of your teeth and gums. Fixing them early can help prevent pain and dental issues later on.

Overbite

An overbite happens when your upper teeth stick out too far over your lower teeth. In some cases, it is called “overjet.” Overbites can make your smile look uneven and cause wear on your front teeth over time, impacting tooth alignment and jaw posture. As Dr. Jeryn Jacob, a well-known orthodontist in Sunnyvale, TX, explains, untreated overbites can also cause gum problems and strain in the jaw over time.

Underbite

An underbite is when your lower teeth extend past your upper teeth. Both overbites and underbites are types of malocclusion, meaning “bad bite.” Left untreated, they can cause chewing issues, jaw strain, or uneven tooth alignment.

What Causes Overbites and Underbites?

Bite problems don’t just happen by chance. They can be caused by many things, from the way your teeth and jaw grow to habits you had as a child. Understanding what leads to overbites or underbites can help you take steps to fix them early.

Genetics

Your genes largely dictate how your jaw and bite develop. If your family members have jaw position or bite alignment issues, you are more likely to face the same challenges.

Childhood Habits

Childhood habits, like thumb-sucking or prolonged pacifier use, can affect how the jaw develops. These habits may push teeth out of place and disrupt normal jaw alignment.

Jaw Development and Tooth Growth

Overbites and underbites may occur if teeth and jaws do not grow evenly. Crowded teeth, gaps, or abnormal alignment can all contribute to these bite issues.

Injuries

An injury to the jaw or teeth, such as from an accident or sports, can lead to bite misalignment. Getting quick dental care can prevent long-term problems.

Why Fix Overbites and Underbites?

Overbites and underbites aren’t just about how your smile looks; they can affect your daily life too. They can make chewing, speaking, or even smiling harder. Correcting your bite can improve your health and well-being in many ways:

Protects Your Teeth

Untreated overbites or underbites may cause cavities, gum disease, or tooth wear. Misaligned teeth can make it hard to fully clean your mouth, resulting in poor oral health. Fixing your bite helps keep your teeth strong and healthy for years to come.

Improves Speech

Bite problems may lead to speech issues, like lisping or mispronouncing words. Fixing your bite allows your tongue and teeth to work together smoothly, making it easier to speak clearly. Better speech can make school, work, and social life easier and more enjoyable.

Relieves Jaw Pain

Extreme bite problems can strain your jaw and lead to TMJ disorders. This can cause headaches, jaw clicking, or even chronic pain. Treatment can ease this discomfort and improve your quality of life. With proper care, your jaw can move more comfortably, and daily tasks like eating and talking become easier.

Boosts Confidence

A straight, well-aligned smile improves your appearance. Feeling confident in your smile has a positive effect on all areas of your life, from social situations to workplace interactions. When you feel good about your teeth, it shows in your smile and the way you carry yourself.

Treatment Options at Carpinello Orthodontics

At Carpinello Orthodontics in Drexel Hill, PA, we offer many treatment options tailored to your needs:

Braces

Braces are a reliable option for correcting bite issues. They guide teeth into proper alignment and are effective for both overbites and underbites. With today’s advances, braces are more comfortable and discreet than ever. Braces are suitable for people of almost all ages. Many patients see big changes within months.

Invisalign

Clear aligners, like Invisalign, offer a nearly invisible way to fix mild to moderate malocclusion. These aligners are removable, which helps you maintain good oral hygiene during treatment. They are easy to take out when eating or brushing, making daily care simple and stress-free.

Palate Expanders

For younger patients, palate expanders guide proper jaw growth and create space for teeth. This early treatment helps prevent crowding and bite problems as children grow. Using a palate expander can make future treatments faster and simpler.

Headgear

In some cases, headgear may be used to guide jaw alignment in children. While it is less common these days, headgear can still play an important role in certain bite correction plans. Your orthodontist will show how to wear it safely and comfortably for the best results.

Jaw Surgery

In severe cases of jaw misalignment or facial asymmetry, surgery may be needed. This option is reserved for extreme cases where braces or aligners alone cannot fix the issue. Carpinello Orthodontics works with skilled oral surgeons to deliver the best results.

Benefits of Fixing Bite Misalignments

Correcting overbites and underbites leads to:

  • Better oral health
  • Improved bite function
  • Enhanced chewing ability
  • Reduced risk of cavities or tartar
  • Fewer headaches or jaw pain
  • Increased confidence

Treatment Costs in Drexel Hill, PA

Costs for bite correction vary depending on the severity of the issue and your treatment plan. Mild problems treated with braces or Invisalign range between $3,500 and $7,500. Severe cases requiring surgery or additional appliances may cost more. At Carpinello Orthodontics, we discuss costs and insurance options at your consultation.

Life After Treatment

Once your treatment ends, retainers help keep your teeth in place. Here’s how to maintain your new smile:

  • Wear Your Retainer: Retainers prevent your teeth from shifting out of place.
  • Stay on Top of Oral Hygiene: Brushing and flossing daily ensures your teeth stay healthy.
  • Regular Checkups: See your orthodontist for routine cleanings and checkups.

Frequently Asked Questions

Can you fix an overbite completely?

Yes, an overbite can usually be corrected completely with the right orthodontic treatment. Depending on the severity, options may include braces, clear aligners (like Invisalign), or even jaw surgery for more complex cases. Your orthodontist will create a personalized treatment plan to realign your teeth and jaw for a healthy, balanced bite.

Does your face change when you fix your overbite?

Yes, correcting an overbite can subtly change your facial appearance, usually for the better. As your teeth and jaw move into proper alignment, your facial profile often looks more balanced and defined. This can enhance your smile, jawline, and overall facial harmony without looking unnatural.

What happens if you never fix your underbite?

If left untreated, an underbite can cause long-term dental and health problems. These may include uneven tooth wear, jaw pain, speech difficulties, and challenges with chewing. Over time, it can also affect facial symmetry and confidence. Early evaluation and treatment can help prevent these issues and improve both function and appearance.
