Understanding Overbites: Causes, Types, and When to Seek Treatment

Understanding Overbites: Causes, Types, and When to Seek Treatment

A confident smile can make a big difference in how we feel, and how others see us. But for many people, dental alignment issues like overbites can stand in the way of that perfect smile. While common, overbites are more than just a cosmetic concern. Left untreated, they can lead to jaw pain, tooth wear, and other long-term complications. The good news? With the right dental care and modern teeth straightening solutions, correcting an overbite has never been more accessible.

In this blog, we’ll break down what an overbite is, explore its causes and types, and help you understand when it’s time to consider dental treatment.

What is an Overbite?

An overbite occurs when the upper front teeth excessively overlap the lower front teeth. A slight overbite is completely normal, in fact, most people have a small one. But when the overlap becomes too large (typically more than 3 mm), it can affect both function and appearance.

There are two main types of overbites:

  • Skeletal overbite – Caused by the shape or position of the jaw.

  • Dental overbite – Caused by the position of the teeth rather than the jaw.

Identifying the type of overbite is the first step in determining the best course of dental treatment.

What Causes an Overbite?

Overbites can develop for a variety of reasons, many of which begin in childhood. Common causes include:

  • Genetics: Just like eye color or height, jaw structure is often inherited. A small lower jaw (mandible) can cause upper teeth to protrude more.

  • Thumb sucking or pacifier use: Extended habits during childhood can push teeth out of alignment, leading to an overbite.

  • Tongue thrusting: This occurs when the tongue presses too far forward in the mouth, which can affect tooth positioning.

  • Teeth grinding (bruxism): Over time, this habit can wear down teeth and change the bite structure.

  • Missing or overcrowded teeth: Both conditions can shift the alignment of surrounding teeth, contributing to bite issues.

Understanding the cause helps dental professionals create a tailored dental care plan to manage and correct the issue.

Signs You Might Have an Overbite

Some overbites are easy to spot just by looking in the mirror. Others might be more subtle. Here are a few signs:

  • Upper teeth significantly overlap the lower teeth when biting

  • Difficulty chewing or speaking clearly

  • Jaw pain or discomfort

  • Worn tooth enamel

  • Frequent headaches or tension in the jaw

If you notice any of these, it’s a good idea to consult with a dentist or orthodontist for a proper evaluation.

When Should You Seek Treatment?

Not all overbites need to be corrected, but many do. It's best to seek dental treatment if:

  • Your overbite is affecting your ability to chew or speak

  • You’re experiencing pain or discomfort in the jaw

  • Your teeth are wearing unevenly

  • The overbite is impacting your confidence or appearance

Early dental care can prevent further complications down the road. While traditional braces are a common solution, clear aligners like Smileie offer a convenient, discreet option for many people.

How Can You Fix an Overbite?

Treatment depends on the severity and the underlying cause of the overbite. Common options include:

  • Clear aligners (like those from Smileie): Ideal for mild to moderate dental overbites. These gradually shift the teeth into alignment without wires or metal brackets. Smileie aligners are especially convenient because they can be used at home under remote supervision, no clinic visits required.

  • Braces: Traditional braces are effective for more complex cases involving jaw structure.

  • Jaw surgery: In severe skeletal cases, especially for adults, corrective jaw surgery may be needed.

  • Tooth extraction: In cases of overcrowding, removing certain teeth may create the space needed to realign the bite.

Whatever the method, the goal is the same: restore balance and function to your smile while improving long-term dental health.
