A beautiful smile is a symbol of confidence and oral health, but some dental issues, like crowded, crooked, and uneven teeth, can affect its appearance and functionality. One of the common concerns is a deep bite, which differs from a normal bite in several ways.
In this guide, we’ll explore “deep bite vs normal bite” and what an exactly deep bite looks like, its causes, and treatment options, including whether ALIGNERCO can fix a deep bite. Why choose ALIGNERCO for professional guidance and a customized treatment to cure your deep bite issue to achieve a healthier smile?
What is a Normal Bite?
A normal bite occurs when the upper and lower teeth align correctly, allowing even pressure distribution during chewing and speaking. In an ideal occlusion:
- The upper front teeth slightly overlap your lower front teeth.
- The molars align properly to support perfect chewing.
- The teeth and jaw function smoothly without discomfort.
A proper bite ensures better oral hygiene, minimizes wear and tear on teeth, and prevents jaw pain or misalignment issues.

What is a Deep Bite?
A deep bite, also known as an overbite, occurs when the upper front teeth excessively overlap the lower front teeth. This condition can be mild to severe, depending on the extent of the overlap. According to studies, deep bites affect nearly 15-20% of the population and are often caused by genetic factors or poor oral habits. An overbite occurs when the upper front teeth excessively overlap the bottom anterior teeth. However, this condition can be mild to severe, depending on the extent of the overlap.
Is a deep bit normal?
A small degree of deep bite is normal. However, if the overlap is excessive, it can lead to various dental issues, and you may require suitable treatment to fix it.
Deep Bite Causes (H2)
Many factors contribute to the development of a deep bite. So, here are some listed that help you to avoid them to protect your beautiful smile:
1. Genetics:
Inherited jaw structure plays a significant role in bite alignment. You will likely have the deep bite issue if your parents have deep bites.
2. Poor Teeth Habits:
Thumb-sucking, prolonged pacifier use, and tongue thrusting during childhood can lead to bite misalignment.
3. Missing or Damaged Teeth:
Loss of molars or excessive enamel wear can cause the remaining teeth to shift, resulting in a deep bite.
4. Orthodontic Issues:
Improper dental development, such as overcrowding or misaligned teeth, can lead to an overbite.
Symptoms of a Deep Bite
- Excessive wear on lower front teeth.
- They may feel jaw pain and temporomandibular joint (TMJ) discomfort.
- Facing difficulties in speech and altered facial aesthetics.
- Also, they higher risk of gum irritation and injury.
A deep bite can lead to serious complications if not corrected early, making treatment essential.
Normal Bite Vs Deep Bite - Key Difference
Feature | Deep Bite | Normal Bite |
---|---|---|
Alignment | Top teeth excessively overlap lower teeth | Top teeth slightly overlap lower teeth |
Oral Health Impact | Increased jaw discomfort and enamel damage | Proper chewing and less wear on teeth |
Speech Difficulties & Appearance | Speech difficulties and beauty concern | No issue |
Risk Factors | Higher risk of gum injuries, TMJ pain, and misalignment | Lower risk of dental problems. |
Understanding these differences highlights why correcting a deep bite is crucial for maintaining oral health.
What is the Acceptable Range for a Deep Bite?
A normal bite, also called an ideal occlusion, occurs when the upper teeth slightly overlap the lower teeth by about 2-3 mm. Therefore, this slight overlap helps you protect the teeth and jaw from excessive pressure.
A deep bite, on the other hand, is characterized by an excessive overlap. It is typically greater than 4 mm, where the upper anterior teeth cover a portion of the lower front teeth. If the overlap is more than 6 mm, it is often considered a severe deep bite, which may lead to dental issues.
According to PMC , deep bites affect approximately 20% of the population with varying degrees of severity. While minor deep bites may not require treatment, moderate to severe cases often need orthodontic intervention to prevent long-term dental complications.
Understanding the difference between a deep bite and a normal bite is essential for maintaining optimal oral health. If you suspect you have a deep bite, consulting a dental professional can help determine the best course of action for your specific condition.
Best Treatment Options for Deep Bite
Correcting a deep bite requires proper orthodontic intervention. The right treatment depends on the severity of the condition and individual patient needs. Below are the most effective treatment options:
Orthodontic treatments
Orthodontic treatments are the best and most effective treatment of your deep bite.
Braces:
Over time, braces can help shift your teeth into the right position with controlled pressure. Brackets and wire are used to move your teeth. It's a costly and uncomfortable process. There are different types of braces, such as lingual braces and ceramic braces. Advanced braces work the same way as metal braces. They are just more subtle-looking. It takes more time to fix your deep bite.

Clear Aligners:
Clear aligners are the best method to cure mild deep bites. ALIGNERCO's nearly invisible aligners help you fix your bite gradually without the need for metal braces, enhancing your smile function as well as its aesthetics. Their clear aligners are made from BPA-free plastic, providing you with a comfortable and smooth treatment remotely. Studies show that clear aligners can effectively treat mild to moderate deep bites by applying controlled pressure on your teeth, ensuring an aligned and balanced bite.

Retainers & Night Guards
Retainers are important after orthodontic treatment to maintain the corrected bite. They prevent teeth from shifting back to their original position. Night guards can also be beneficial for individuals who grind their teeth (bruxism), which can contribute to bite misalignment over time.
Dental Crowns & Restorations
When the deep bite has caused excessive wear on teeth, veneers, dental crowns, or other restorative procedures are required in extreme cases. These treatments help recreate damaged teeth and improve overall bite function. According to PMC studies, properly placed restorations can restore normal bite function and prevent further complications related to deep bites.
