Causes of reverse bite 

The way your teeth are aligned may be affected by several factors, the teeth usually grow in a way that makes the upper teeth consistent with the lower teeth, and your teeth must also fit (wide flat teeth at the back of your mouth) with each other, and the consistency of the correct teeth prevents you from biting your cheeks, lips or tongue when eating/ There are many factors that can cause a person to suffer from the lower bite, and these factors include:  

Childhood habits 

Some childhood habits may increase the risk of bad tooth bite or other dental abnormalities and factors contributing to the bite include 

  • Thumb sucking. 
  • Pressing the teeth with the tongue. 
  • Use the pacifier for children over 3 years old. 
  • Long-term lactation. 


  • Most often the bite is inherited, and your likelihood of getting a bite increases if at least one other person in your family also gets it, genes also determine the shape and size of the jaw and teeth
  • someone may be born with teeth that are too close to each other, have an abnormal shape, or do not fit together properly, and some defects may also appear at birth such as cleft lip or cleft palate. 

Injury to the face

  • Severe facial injuries may cause permanent damage to the jawbones, and often it is possible to repair broken jaw bones, but the jaws do not always fit together properly after being surgically realigned, and this can cause the bite. 
  • Tumors on the jaw bones or in the mouth may cause the jaws to protrude, causing a lower bite.

Treatment of inverted bite in teeth

  •  Most people are not born with perfectly coherent teeth, and slightly misaligned teeth usually do not require any medical treatment, but for the bite, especially when it is severe, treatment is necessary. 
  • Repairing a bite will make brushing teeth easier, reduce your risk of tooth decay and gum disease, and will also feel less stress on your teeth, jaw, and facial muscles this can reduce the risk of tooth fracture as well as the painful symptoms of temporomandibular disorders common with lower bites. 

Some common bite treatments include 

Home treatment 

Brushing and flossing regularly and visiting your dentist for checkups and cleanings are important to your dental hygiene routine. 

  • Those who suffer from a lower bite or other dental problems should take special care of their teeth to prevent further damage and decay. Brush your teeth at least twice a day for two minutes each time with fluoride toothpaste and pay attention to brushing along the gum line and on the inside, outside, and back of the mouth.
  •  Be sure to floss in addition to brushing. 

See your dentist at least twice a year for checkups and cleanings.

Medical treatment 

is the only way to correct the reverse bite and align the teeth correctly at the very least, and medical treatment can improve the appearance of the lower bite. In cases of less severe bites, the dentist may be able to use an orthodontic appliance and wire or plastic braces to move the teeth into place. 

  • Removing one or more teeth in the lower jaw may also help improve the appearance of the lower bite if overcrowding is contributing to the problem. 
  • The dentist can also use a grinding device to smooth large or protruding teeth. 
  • In more severe cases of bite, your dentist may recommend surgery to correct the condition. 

Reverse bite surgery

Most certified oral surgeons are able to successfully correct bumps, and many common types of surgery to correct the lower bite include reshaping to lengthen the upper jaw or shorten the lower jaw.

  • In some cases, the use of wires, plates, or screws may maintain the proper shape of the jawbone, and surgery comes with many risks including those associated with general anesthesia, infection, bleeding problems, and scarring. 
  • Surgery involves examination, X-rays, general anesthesia, bone cutting, bone reshaping, and jaw repositioning. 
  • Screws, plates, wires, and rubber bands also hold the jaw in place after surgery. 
  • Recovery from jaw surgery takes one to three weeks, and the dentist often recommends using braces or other dental devices after surgery to keep the teeth in place. 

Inverted bite is an uncommon dental condition that can affect not only your self-esteem but also your quality of life, it is possible to treat or even completely correct the deficiency, so visit your dentist to learn more about your treatment options and to determine what works best for you.
