A captivating smile isn’t just a superficial attribute; it’s a testament to both oral well-being and self-assurance.

If you find yourself dissatisfied with your smile due to misaligned or crooked teeth, the culprit might be lurking in the form of overjet or overbite

These terms encapsulate two common malocclusions, or improper bites, which can impact not only your appearance but also your oral health and functionality.

Fear not – for there exists effective treatment capable of steering you towards a straighter and healthier smile.

Join us on an illuminating journey through the intricacies of overjet and overbite, as we unravel their origins, explore diverse treatment avenues, and uncover why clear aligners stand out as a revolutionary solution.

A review of studies in the Dental Press Journal of Orthodontics revealed the prevalence of overjet and overbite in the global population

Overjet is like a rebel among teeth, constantly pushing the upper front teeth outward, creating a horizontal gap when you bite down. 

It’s the dental equivalent of ‘buck teeth’ or ‘rabbit teeth’—terms that, let’s admit, sound a bit whimsical despite describing a real condition.

Now, let’s clear up a common misconception—overjet isn’t the same as overbite. Overbite involves a vertical overlap of the upper and lower teeth, a different kind of dental complication. 

Yet some folks end up with both overjet and overbite, turning their dental ordeal into a more complex and intriguing story.

Normal Overjet

An overjet, sometimes referred to as buck teeth, is a dental condition where the upper teeth protrude outward and sit over the bottom teeth. 

This condition can affect not only your appearance but also your ability to chew, drink, and bite. It may even cause jaw pain.

The normal range for an overjet is when the upper front teeth rest slightly in front of your lower teeth when closing your mouth, they’re usually 2 millimeters (mm) apart. 

However, if your upper front teeth extend in front of your lower teeth by more than 2 mm, it is considered an overjet.

Causes of Normal Overjet

There isn’t a single cause for an overjet, but rather different variables that can contribute to this condition. 

Sometimes, an overjet is hereditary. So if your mother or father has one, you might develop one, too. 

An overjet can also form if you had a habit of sucking your thumb or fingers as a child. Having a tongue thrust can also lead to an overjet, as can using a pacifier for an extended period.

Reverse Overjet

A reverse overjet, also known as an underjet, is a condition where the lower teeth protrude or splay out. 

This condition often occurs when the lower jaw is ‘oversized’, or the upper jaw is undersized or a combination of both. This usually results in the front teeth biting the wrong way around.

Celebrities with Overjet Teeth

Despite the challenges that come with having an overjet, many celebrities have embraced this unique feature. 

For instance, Freddie Mercury, the iconic Queen frontman, reportedly resisted fixing his teeth because he was concerned that it would change his voice. 

Other celebrities known to have overjets include actor Tom Cruise and supermodel Cindy Crawford.

Whether it’s a normal overjet or a reverse one, it’s important to remember that everyone’s smile is unique. 

And as our celebrity examples show, an overjet doesn’t have to hold you back from achieving greatness.

What causes overjet?

Overjet takes center stage in the intricate realm of dental dynamics. 

Delving into the origins of this condition requires a professional lens, examining the nuanced interplay of various factors:

Genetics: Inherited predisposition—small lower jaw or expansive upper jaw—contributes to teeth misalignment, establishing a familial link to overjet.

Habits: Thumb sucking, tongue thrusting, and prolonged use of pacifiers or bottles impact dental development, influencing jaw structure and teeth positioning.

Tooth Loss: Decay, injury, or intentional extraction leading to tooth loss creates voids, prompting remaining teeth to shift and fostering the emergence of overjet.

Trauma: Injuries to the jaw or face become defining moments, leaving a lasting impact on teeth alignment and the orchestration of the bite, positioning trauma as a significant influencer in the overjet narrative.

A study published in The Angle Orthodontist discussed a patient who had an overbite, which was primarily the result of a thumb-sucking habit

What are the problems caused by overjet? 

Let’s decode the impact of overjet, uncovering a spectrum of challenges that extend beyond the visible:

Aesthetic Concerns: Overjet affects self-esteem and confidence, leading to potential embarrassment or insecurity about one’s smile.

Oral Health Implications: Cleaning becomes challenging, elevating risks of plaque, cavities, and gum disease. Overjet accelerates teeth wear, causing sensitivity, cracks, or fractures.

Functional Hurdles: Biting, chewing, speaking, and breathing face disruptions. Stress on jaw muscles and joints may result in pain, headaches, or temporomandibular disorders (TMD).

Overjet isn’t just a cosmetic issue; it poses challenges to aesthetics, oral health, and functional aspects, demanding a comprehensive approach to resolution.

What is overbite?

Imagine you bite down, and your upper front teeth steal the show by covering a bit too much of their lower counterparts. 

This condition is what we call overbite, and it adds a vertical layer to the tale of our teeth. In the dental world, it’s affectionately known as a ‘deep bite,’ owing to the substantial depth of this tooth overlap.

Now, let’s clear up a common misconception—overbite isn’t a horizontal movement like its counterpart, overjet. 

Overbite is all about the vertical embrace of the upper teeth over the lower ones. 

Yet, here’s the intriguing twist: some individuals find themselves with both overbite and overjet, making their oral treatment more complex.

What causes overbite?

Several factors can contribute to overbite, these include:

Genetics: Inherited traits like a large upper jaw or a small lower jaw contribute to teeth misalignment, fostering overbite.

Habits: Habits, including thumb sucking and prolonged use of pacifiers, shape jaw development, and tooth positioning, influencing overbite.

Tooth Size: Small or crowded teeth create gaps, allowing upper teeth to gracefully overlap lower ones in the overbite scenario.

Jaw Growth: Uneven or abnormal jaw growth becomes a director, influencing teeth alignment and the intricate dance of the bite in an overbite.

Before and After: A Visual Journey

Navigating Overbite Challenges

Embarking on the journey through overbite unveils a spectrum of challenges that extend beyond the surface. 

These include:

Aesthetic Concerns: Impact on appearance and smile, potentially leading to a “gummy” smile or a distinctive “bulldog” look.

Oral Health Implications: Cleaning challenges elevate risks of plaque, cavities, and gum disease. Overbite accelerates teeth wear, causing sensitivity, cracks, or fractures.

Functional Hurdles: Disruption in biting, chewing, speaking, and breathing, with potential stress on jaw muscles and joints causing pain, headaches, or temporomandibular disorders (TMD).

How to Treat Overjet and Overbite?

The best treatment option depends on the severity of your condition, your age, your budget, and your preference.

Embarking on the journey to correct overjet and overbite unveils a range of orthodontic methods, each with its pros and shortcomings:

Braces: Traditional method with metal wires and brackets. Effective but comes with discomfort, cleaning challenges, dietary restrictions, and aesthetic concerns.

Appliances: Devices like headgear, palatal expanders, retainers, and bite plates. Used alone or with braces for mild to moderate cases. May cause discomfort, inconvenience, and social considerations.

Surgery: Reserved for severe cases. Involves cutting and reshaping jaw bones. Transformative but invasive and risky.

Clear Aligners: Modern, custom-made plastic trays. Removable, comfortable, easy to clean, and virtually invisible. Effective for mild to severe cases, often faster than braces or appliances.

Each method offers distinct benefits and considerations, paving the way to a beautifully aligned smile. Consult your orthodontist to verify the best option for you.
