What is an Overbite?
An overbite 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 normal, but when it’s excessive, it can affect the way your teeth come together and function.
Some overbites are caused by the position of the teeth, while others are related to the way the upper and lower jaws have developed. The severity can vary from person to person, which is why an orthodontic assessment is the best way to understand what’s causing the problem and whether treatment is recommended.
What Causes an Overbite?
Overbites can develop for a number of reasons. Genetics is one of the most common causes, influencing the way the teeth and jaws grow. Differences in jaw development, the position of the teeth and certain childhood habits, such as prolonged thumb sucking or dummy use, may also contribute.
Understanding what’s causing the overbite is an important part of planning treatment, as the most appropriate approach depends on whether the problem involves the teeth, the jaws or both.
How Can an Overbite Affect Your Teeth and Bite?
An untreated overbite, especially if it’s pronounced, can lead to several concerns such as:
Tooth wear and damage: The disproportionate overlap of the upper teeth over the lower ones can lead to excessive wear on the tooth enamel. This wear can make teeth more vulnerable to chipping, cracking and sensitivity due to exposure of the underlying dentin.
Chewing and digestion concerns: An overbite can affect the alignment and function of the back molars, making chewing less efficient. Inefficient chewing can indirectly influence digestion, as the process of digestion begins in the mouth with adequately chewed food mixed with saliva.
Speech difficulties: Just as an underbite can affect speech, an overbite can as well. The misalignment might lead to lisps or other articulation challenges, making certain sounds difficult to pronounce.
Aesthetic concerns: From a cosmetic perspective, a pronounced overbite can affect the profile of an individual, making the chin look recessed or the lips appear protruded. This might lead to self-consciousness and reduced confidence.
How Is an Overbite Treated?
There isn’t a single treatment for every overbite. The most appropriate approach depends on what’s causing the problem, how severe it is and whether it’s related to the teeth, the jaws or a combination of both.
For many patients, braces can be used to gradually improve the position of the teeth and the way the bite comes together. For younger children, early orthodontic treatment may sometimes be recommended if jaw growth is contributing to the overbite. More complex cases may require additional treatment planning to achieve the best long-term outcome.

When Should an Overbite Be Assessed?
If you’re concerned about the way your teeth or your child’s teeth come together, it’s worth arranging an orthodontic assessment. While some overbites are mild, others can affect the way the teeth function or wear over time.
Dr Nino will assess the position of the teeth and jaws, explain what’s contributing to the overbite and recommend whether treatment, monitoring or simply reviewing the bite as it develops is the most appropriate next step.
Frequently Asked Questions
Are Overbites Common?
Yes. Overbites are one of the most common bite problems seen by orthodontists. A small amount of overlap between the upper and lower front teeth is completely normal, but when the overlap is excessive, it can affect the way the teeth function and come together.
What is the difference between an overbite and an overjet?
An overbite describes how much the upper front teeth vertically overlap the lower front teeth. An overjet refers to how far the upper front teeth protrude in front of the lower teeth. Some people have one condition, while others have both.
Will my child's overbite improve as they grow?
Some bite changes occur naturally as children develop, but a more significant overbite doesn’t always correct itself. An orthodontic assessment can help determine whether treatment is recommended or whether it’s appropriate to simply monitor your child’s development.
What happens if an overbite is left untreated?
Depending on its severity, an overbite may contribute to uneven tooth wear, increased pressure on certain teeth or gums, or affect the way your teeth come together when you bite. Dr Nino can assess whether treatment is recommended based on your individual situation.
Can an overbite get worse over time?
It can. As the teeth shift naturally and the jaws continue to develop, an overbite may become more noticeable. Early assessment can help determine the right time to begin treatment if it’s needed.
