What Is a Deep Bite?
A deep bite is a type of bite problem where the upper front teeth overlap the lower front teeth more than they should when the mouth is closed. A small amount of overlap is completely normal, but when it’s excessive, it’s known as a deep bite.
In some cases, the lower front teeth may contact the roof of the mouth behind the upper teeth or the lower teeth may become almost completely hidden. Depending on its severity, a deep bite can affect the way your teeth function and may contribute to excessive tooth wear, gum irritation or jaw discomfort over time.
What's the difference between a deep bite and an overbite?
A small overbite is a normal part of a healthy bite and describes the vertical overlap of the upper front teeth over the lower front teeth.
A deep bite is simply an excessive overbite, where the upper front teeth overlap the lower teeth more than they should. While the terms are sometimes used interchangeably, orthodontists often use deep bite to describe a more significant problem that may require treatment.
What Causes a Deep Bite?
Deep bites can develop for a number of reasons. Genetics is one of the most common causes, influencing the way the teeth and jaws grow. In some people, the upper and lower jaws develop differently, while in others the position of the teeth contributes to the problem.
Factors that may contribute to a deep bite include:
- Genetics
- Differences in jaw growth and development
- Tooth eruption patterns
- Tooth wear or missing teeth in some adults
How Can a Deep Bite Affect Your Teeth and Bite?
Tooth Wear
A deep bite can place excessive pressure on the front teeth, leading to increased wear over time.
Gum Irritation
In more severe cases, the lower front teeth may contact the gum behind the upper front teeth, causing irritation or trauma.
Jaw Pain and TMJ Disorders
A deep bite can affect the way the teeth and jaws work together, which may contribute to jaw discomfort for some people.
Biting and Chewing
When the bite doesn’t come together properly, biting into certain foods may become more difficult.
Smile Appearance
A deep bite can affect the appearance of your smile by making the lower teeth less visible when you smile or speak.
How Is a Deep Bite Treated?
Treatment depends on the cause and severity of the deep bite. In many cases, braces can gradually improve the position of the teeth and create a more balanced bite.
If jaw development is contributing to the problem, treatment may vary depending on your age and stage of growth. Following a comprehensive assessment, Dr Nino will explain what’s causing the deep bite and recommend the treatment approach that’s most appropriate for your individual needs.

When Should a Deep Bite Be Assessed?
If you or your child have a bite where the upper front teeth appear to cover most of the lower front teeth, it’s worth arranging an orthodontic assessment.
Early assessment doesn’t always mean treatment is needed immediately, but it allows Dr Nino to monitor growth, identify the underlying cause and recommend the most appropriate timing if treatment is required.
Adults can also benefit from assessment if they’re experiencing excessive tooth wear, gum irritation or concerns about the way their bite functions.
Frequently Asked Questions
What's the difference between a deep bite and an overbite?
An overbite describes the vertical overlap of the upper front teeth over the lower front teeth. A deep bite is an excessive overbite, where the upper teeth cover the lower teeth more than they should.
How do I know if I have a deep bite?
You may have a deep bite if your upper teeth significantly cover your lower teeth or if you notice jaw discomfort, tooth wear, or difficulty biting food. An assessment from Gullotta Orthodontics can confirm the diagnosis.
Is a deep bite bad if it doesn’t hurt?
Even if it is not painful, a deep bite can still cause long-term issues such as tooth wear, gum damage and jaw strain. Early assessment helps prevent these problems from developing over time.
Can adults have treatment for a deep bite?
Yes. Deep bites can be successfully treated in both teenagers and adults. After assessing your teeth and bite, Dr Nino will explain the treatment options that are most appropriate for your situation.
When should a child be assessed for a deep bite?
Children should have an orthodontic assessment by around age 7. Early intervention can guide jaw growth and reduce the need for more complex treatment later.
