Deep Bite vs Overbite – Understanding the Difference

Posted on August 3, 2025

At Lustig & Young Orthodontics, many patients come to us unsure about the difference between a deep bite vs overbite. The two terms are often used interchangeably, but they actually describe different bite conditions that can affect your smile, comfort, and long-term oral health.

If you’ve ever noticed that your top teeth overlap your bottom teeth more than usual, or you’ve been told you have one of these bite issues, this guide will help you understand what they mean—and how orthodontic treatment can correct them.

What Is an Overbite?

An overbite is a type of malocclusion where the upper front teeth vertically overlap the lower front teeth. A slight overbite is completely normal and necessary for proper function. Most people have an overbite of about 2–4 millimeters, which allows for an even bite and a natural appearance.

However, when the overlap is too large—covering more than 30% of the lower teeth, it becomes excessive. This can lead to problems such as uneven wear, gum irritation, or even jaw discomfort.

What Is a Deep Bite?

A deep bite, sometimes called a deep overbite, is a more severe form of overbite. In this case, the upper front teeth overlap the lower front teeth so much that the lower teeth may touch the gum tissue or roof of the mouth.

You might have a deep bite if you notice:

• Your upper front teeth cover most or all of your lower front teeth when you bite down.
• Your lower teeth appear shortened or hidden.
• You have jaw discomfort or uneven tooth wear.

A deep bite can cause both aesthetic and functional issues, making treatment important not just for appearance, but for long-term oral health.

Deep Bite vs Overbite: Which Is Worse?

When comparing a deep bite vs overbite, a deep bite is generally considered more serious. While a mild overbite is normal, a deep bite can lead to a variety of complications, such as:

• Tooth Wear and Damage: Excessive overlap causes friction that wears down the enamel, leading to sensitivity or chipped teeth.
• Gum Irritation: In severe cases, the lower teeth may press into the gum tissue behind the upper front teeth, causing discomfort or recession.
• Jaw Pain: Deep bites can contribute to jaw strain or temporomandibular joint (TMJ) discomfort.
• Facial Changes: A deep bite can make the lower face appear shorter and the chin more prominent.
• Difficulty Chewing or Speaking: Misalignment may make eating or speaking feel awkward or tiring.

While an overbite can often be managed with minor orthodontic treatment, a deep bite usually requires correction to prevent long-term damage.

Does a Deep Bite Need to Be Treated?

Yes. Correcting a deep bite isn’t just about aesthetics—it’s about protecting your teeth, gums, and jaw. Treatment helps:

• Prevent Tooth Wear: Reducing the overlap stops enamel erosion and uneven wear.
• Improve Oral Hygiene: Proper alignment makes brushing and flossing easier, lowering your risk of cavities and gum disease.
• Relieve Jaw Discomfort: Adjusting your bite can reduce strain on the jaw joint.
• Enhance Your Smile: Correcting a deep bite can restore balance and improve your facial profile.

At Lustig & Young Orthodontics, we often recommend treating deep bites early, especially in children and teens, to prevent future dental issues and support healthy jaw development.

Treatment Options for Deep Bite and Overbite

The best treatment for your bite depends on your age, the severity of the overlap, and your overall dental health. Here are some of the most common solutions we offer:

1. Braces

Traditional braces are one of the most effective treatments for correcting both deep bites and overbites. They gradually move teeth into better alignment using steady, gentle pressure.

For deep bites, we may use techniques such as:

• Bite ramps or plates to prevent lower teeth from hitting the gums.
• Special archwires that help level the bite and create proper spacing.

2. Clear Aligners

For mild to moderate bite issues, clear aligners (like Invisalign®) are a great option. They are removable, nearly invisible, and custom-made to guide your teeth into alignment. Aligners can correct an overbite and, in some cases, mild deep bites with consistent wear.

3. Functional Appliances

For younger patients, functional appliances help guide jaw growth and muscle development to correct the bite before it becomes more severe. Early intervention can often reduce the need for complex treatment later.

4. Tooth Extraction

If overcrowding contributes to the deep bite or overbite, selective extractions may be recommended to create space for proper alignment.

5. Orthognathic Surgery

In rare, severe cases—often involving jaw misalignment—jaw surgery (orthognathic surgery) may be required. This is typically combined with orthodontic treatment to achieve the best functional and aesthetic result.
