A slight overbite can be normal, but in the case of a severe overbite, it might cause problems with your dental health. A dentist or orthodontist may be able to evaluate your bite and recommend treatment if necessary. Possible treatments include traditional braces, Invisalign, tooth extraction, and oral surgery.

What Is An Overbite?

An overbite, sometimes referred to as a “deep bite,” is the vertical misalignment of the teeth. With an overbite, the top teeth overlap the bottom teeth more than normal. Dental professionals consider an overbite of between two and four millimeters a potential concern. [1]

An overbite is sometimes confused with an overjet. However, an overjet is a horizontal malocclusion resulting in teeth that stick out from the mouth, also known as buck teeth.

Types of Overbites

Generally, there are two types of overbites: skeletal overbites and dental overbites. [2] Skeletal overbites are caused by abnormalities in jawbone development. Dental overbites are those that involve the emergence of adult teeth when baby teeth are lost.

Overbite Causes

Some overbites are genetic, while others may be caused by certain environmental factors. Some preventable risk factors for overbites include: [3]

• Prolonged thumb-sucking
• Pacifier use after the age of 3
• Drinking from traditional sippy cups
• Teeth grinding, also known as bruxism
• Tongue-thrusting
• Nail biting

Overbite Diagnosis

Overbites are typically observed during routine oral examinations by your dentist. In some cases, X-rays may be required to determine whether treatment is necessary. Many times, dentists will refer patients to an orthodontist to address this common type of misalignment.

Is An Overbite Bad? Why Fix Overbites?

Some people with overbites want them corrected because they want a more aesthetically pleasing smile. However, there may be other reasons to fix an overbite, including the risk of certain dental health issues: [4]

• Risk of Tooth Decay: An overbite can result in the erosion of the upper front teeth, which could lead to tooth decay over time.
• Gum Damage: An overbite can put excessive pressure on the gums behind both the upper and lower front teeth, causing periodontal issues such as gum recession.
• Chewing Problems: An overbite can make it hard to chew properly.
• Orthodontic Issues: An overbite is often considered an orthodontic issue itself, but it can cause other orthodontic issues, such as overcrowding or misaligned teeth.

Treatments for Overbite Correction

There are various ways to treat an overbite. Your dentist may recommend a treatment plan based on your age, the severity of the bite, and your preferences. Possible overbite treatments include: [5]

• Traditional or clear braces
• Invisalign
• Headgear
• Retainers
• Tooth extraction
• Jaw surgery
• Palate expanders

How to Manage an Overbite

If you’re living with an overbite and aren’t prepared to address it with a dental professional yet, there are some things you can do to prevent the situation from getting worse:[6]

• Practice good oral hygiene.
• Use a night guard for tongue-thrusting and teeth grinding during sleep.
• Use a mouth guard for sports.

Make A Dental Appointment

If you’re concerned about your overbite, or your child’s, the best course of action is to make an appointment with your dentist or orthodontist. They can evaluate the bite and make personalized recommendations for treatment. A brighter, healthier smile is within reach.
