An overbite is one of the most common orthodontic concerns, and the good news is that it is also one of the most treatable.
Whether you have noticed that your upper teeth overlap your lower teeth more than usual, or a dental professional has pointed it out during a routine checkup, understanding how to fix an overbite starts with knowing what causes it and what your treatment options look like.
What Is an Overbite and How to Fix It?
An overbite refers to the vertical overlap between your upper and lower front teeth. When you close your mouth, your upper teeth naturally sit slightly in front of and over your lower teeth. This is normal. However, when that overlap is too deep, meaning the upper teeth cover a significant portion of the lower teeth, it is classified as a malocclusion that often benefits from orthodontic attention.
Overbites are measured as a percentage of how much the upper teeth overlap the lower ones. A mild overbite of up to 25 percent is generally considered within a normal range. An overbite of 50 percent or more is typically categorized as significant, and an extreme overbite, where the upper teeth nearly or completely cover the lower teeth, usually requires active treatment.
What Causes an Overbite?
Several factors can contribute to the development of an overbite, and many of them begin in childhood.
-
Genetics: Jaw size and tooth positioning are inherited, so if a parent had an overbite, children may be more likely to develop one as well.
-
Thumb sucking and pacifier use: Prolonged habits during early childhood can push the upper teeth forward and alter jaw development.
-
Tongue thrusting: Pressing the tongue against the front teeth consistently over time can shift tooth positioning.
-
Tooth loss: Missing teeth, particularly molars, can cause the remaining teeth to shift in ways that affect bite alignment.
-
Jaw growth patterns: In some cases, the upper or lower jaw develops in a way that naturally creates a deeper bite relationship.
How to Tell If You Have an Overbite
The most accurate way to assess whether you have an overbite is through a professional orthodontic evaluation, where X-rays and bite measurements are used to determine the extent of the overlap.
However, there are some signs you might notice on your own. If your upper front teeth seem to cover most or all of your lower front teeth when you bite down, or if your lower teeth appear to bite into the roof of your mouth, these are both indicators that your bite may benefit from assessment.
Overbite vs. Normal Bite
Understanding the difference between an overbite and a normal bite can be helpful. In a normal bite, the upper teeth sit slightly in front of the lower teeth, and there is a small, measured overlap. In an overbite, that overlap is deeper than ideal, which can affect how the teeth meet and how chewing forces are distributed. Over time, a significant overbite can contribute to uneven tooth wear, jaw discomfort, and sometimes changes in facial appearance.
Can Braces Fix an Overbite?
Yes, braces are one of the most effective tools for correcting an overbite. Traditional metal braces work by applying continuous, carefully controlled pressure to move teeth into their ideal positions and, over time, to address the underlying bite relationship. Orthodontists may use elastic bands worn between upper and lower brackets to help guide the jaw into a better position as part of overbite correction with braces.
The length of treatment depends on the severity of the overbite, the patient's age, and the specific approach the orthodontist uses. In general, more significant overbites take longer to fully correct.
Overbite Correction with Clear Aligners
Can Invisalign fix an overbite? In many cases, yes. Clear aligners have become an increasingly effective option for overbite correction, particularly for mild to moderate cases. Aligners use a series of custom-fit trays to move teeth gradually, and they can also incorporate features like precision bite ramps that help improve the vertical relationship between the upper and lower teeth.
For more detailed information on this option, you can explore whether Invisalign can fix an overbite and what adults and teens should know about this approach.
Different Types of Overbites and How They Affect Treatment
Not all overbites are the same, and the appropriate treatment approach depends on the type.
Dental Overbite
A dental overbite involves the positioning of the teeth themselves, rather than the jaw. In these cases, orthodontic treatment with braces or aligners is often sufficient to bring the teeth into proper alignment.
Skeletal Overbite
A skeletal overbite involves the relationship between the upper and lower jaws. When the upper jaw is significantly larger or protrudes more than the lower jaw, the resulting overbite may require treatment that addresses jaw growth or position. In younger patients, orthodontic appliances that influence jaw development can be used effectively. In adults, severe skeletal overbites may sometimes require surgical consultation in addition to orthodontic treatment.
Correcting an Overbite at Different Ages
Overbite correction tends to be most straightforward in children and adolescents, because the jaw is still growing and can be more readily guided into better alignment. That said, adults can and do achieve excellent results with orthodontic treatment. The key is seeking a professional evaluation, since the approach will differ based on age and jaw development.
What Happens If an Overbite Is Left Untreated?
An extreme overbite that is not treated can lead to a range of issues over time. These may include accelerated wear on specific teeth, increased risk of chipping or fracture, jaw discomfort, and in some cases, difficulty chewing or speaking comfortably. Addressing an overbite with the guidance of an orthodontist helps protect both your dental health and your long-term bite function.

Frequently Asked Questions
Is it possible to fix an overbite without braces?
Clear aligners can be an effective alternative to braces for many patients with mild to moderate overbites. Severe or skeletal overbites may require more comprehensive treatment approaches. An orthodontic consultation is the best way to determine what is right for your specific situation.
How long does overbite correction take?
Treatment duration varies depending on the severity of the overbite and the method used. Mild corrections may take around twelve months, while more significant overbites may require longer treatment periods. Your orthodontist can provide a more accurate estimate after evaluating your bite.
