What is overbite? Causes, harms and treatment method?

Overbite is a malocclusion case that causes the upper and lower jaw to lose balance. Overbite affects chewing ability and facial aesthetics. To better understand this malocclusion as well as find the right treatment, readers can refer to the summary of experts' sharing through the article below. 

What is overbite? 

Overbite is a term used to describe malocclusion caused by an asymmetry between the two jaws. That is, the upper and lower jaws are not the same, the upper jaw will fold inward compared to the other. This condition can be found in both children and adults. 

The severity of the overbite is based on the ratio of the upper tooth surface to the opposite jaw. The higher the percentage, the more serious the overbite. Therefore, it is necessary to treat immediately to avoid negative effects on dental health. 

Features of identifying overbite

  • The correlation between 2 jaws does not reach the standard ratio. When the mouth is at rest, the upper jaw almost obscures the lower jaw, so the lower teeth are often invisible.
  • The lower teeth may or may not touch the upper teeth. If overbite is severe, the upper teeth will be in contact with the inner gum instead of the lower teeth.
  • Molar teeth are still in contact with each other, but the contact area is more or less dependent on the light or heavy overbite.
  • The line between the forehead - nose - chin can be straight or broken depending on each person's overbite level 


There are 3 main causes:

  • Genetic

If one parent has overbite, 70% of babies are born with this trait. 

  • Jaw bone

When the teeth and upper jaw bone grow too strong or the jaw bone is underdeveloped (or stops growing), it will lead to the lower jaw falling inward, causing cosmetic loss. 

  • Bad habit

Certain childhood habits that involve pushing the tongue against the back of the front teeth can cause overbite. These are: using a pacifier, a bottle for a long time, a habit of thumb sucking or tongue thrusting. If a child has had a genetic over bite, these bad habits can make the disease worse.

Some other causes: nail biting, excessive teeth grinding or sucking, biting hard objects such as pens at a growing age... can also lead to overbite.

Is overbite dangerous?

Similar to other malocclusion conditions, overbite can also lead to some serious damage to dental health. Such as:

  • Aesthetic loss 

The protruded upper jaw covering the lower jaw will make the smile less charming and unnatural. At that time, the patient always feels self-deprecating, afraid in communication, making life and work difficult. 

  • Chewing function is decreased

The two jaws are hard to touch, making it difficult to bite and chew. Over time, it seriously affects the digestive system, causing diseases such as stomach pain, stomach ...

  • Upper teeth are worn

If not being treated early, overbite will cause enamel wear on the upper teeth. At that time, the dentin will be exposed causing sensitivity, pain when eating, dental hygiene.

  • Increasing risk of dental disease

When tooth enamel is worn away, bacteria will attack and cause dental diseases.

  • Temporomandibular joint injury

Overbite that takes place for a long time also causes temporomandibular joint disorders, jaw joint pain. 

Therefore, overbite treatment is extremely necessary. However, you should be careful when choosing clinic for treatment as well as an appropriate method to ensure good results and safety for health.

Effective and safe treatment method

Before treating overbite, the patient needs to perform some basic dental procedures to determine whether overbite is caused by the teeth or by the jawbone. From there, the doctor comes up with an appropriate treatment plan.

  • By teeth

If overbite is caused by teeth, doctor will consult patient to take orthodontics for the best result. 

Orthodontics is a solution that uses orthodontic appliances such as brackets, wires or clear aligners to move misaligned teeth to the correct position on the jaw. At the same time, it can create a balance and harmony for the upper and lower jaw. 

Treatment time can take about 1-2 years, can also be faster or longer depending on overbite level.

  • By jawbone

Overbite caused by the jaw bone is considered more serious than that caused by the teeth. At this time, bracing only partially meets, or sometimes do not work.
