Understanding the Causes of Overjet and How to Fix It

表参道 歯並び矯正  is a common dental condition where the upper front teeth protrude significantly over the lower front teeth

While some use the terms interchangeably, overjet and overbite are fundamentally different

An overbite refers to the vertical overlap of the upper teeth over the lower teeth

While overjet is the horizontal distance between them

When the horizontal gap becomes abnormal, it may lead to functional challenges and increased risk of dental problems

Several factors can cause overjet

Genetic predisposition is among the leading causes of overjet

Children with relatives who had overjet are statistically more prone to it themselves

Habits including thumb-sucking, bottle-feeding beyond infancy, or tongue thrusting can misalign teeth over time

Over time, these actions guide the upper teeth into an increasingly protruded position

Delayed loss of baby teeth or early loss can also contribute

Early exfoliation may result in crowding or ectopic eruption of adult teeth

On the other hand, if baby teeth are retained too long, they can block the proper alignment of adult teeth

Differences in the size or position of the upper and lower jaws are significant contributors

A discrepancy where the upper jaw protrudes or the lower jaw is recessed creates an exaggerated horizontal gap

Treatment for overjet is tailored based on its origin and how pronounced it is

The adolescent growth phase offers optimal opportunities for non-surgical correction

Braces are the most common solution, helping to gradually move the teeth into their correct positions

Functional orthopedic appliances are effective in modifying jaw relationships during growth spurts

Treating overjet during childhood maximizes the potential for natural correction

Correcting overjet in adults often requires a multidisciplinary approach

Dental movement alone cannot resolve significant skeletal discrepancies in adults

Maxillary or mandibular osteotomies can correct severe jaw imbalances

For less severe cases, removable aligners can gradually retract protruding front teeth without metal brackets

It is important to address overjet not just for cosmetic reasons but for long-term oral health

Overjet increases vulnerability to chipping, fracturing, or complete avulsion of incisors

Lip incompetence due to overjet promotes bacterial growth and enamel erosion

Overjet can interfere with the mechanics of biting into food, reducing dietary variety

Overjet can cause articulation difficulties, particularly with “s” and “t” sounds

Routine pediatric dental visits are crucial for early malocclusion detection

If you or your child shows signs of protruding upper teeth, consult an orthodontist

Your orthodontist will consider skeletal maturity, dental crowding, and facial profile when designing your treatment

The sooner overjet is addressed, the less complex and costly treatment becomes

Treatment options like braces, Invisalign, or surgery restore proper occlusion, enhance appearance, and boost self-esteem
