An open bite is a form of malocclusion, or teeth misalignment, where the upper and lower teeth do not come into contact when the mouth is closed, leaving a visible gap. This condition can be either an anterior open bite, occurring at the front of the mouth, or a posterior open bite, occurring at the back.
Open bites can be caused by skeletal problems, thumb sucking or prolonged use of pacifiers during childhood, genetic factors, and temporomandibular joint (TMJ) disorders. Typically, this disorder can result in speech difficulties, problems with biting and chewing, and excessive wear on the remaining teeth that make contact.

An open bite can result from several underlying issues, such as skeletal, soft tissue, or dental problems, and sometimes a combination of these factors.
Additional factors contributing to an open bite include:
Regardless of the causes of an open bite, an orthodontist can assess the problem and provide an appropriate treatment plan.
The most apparent sign of an open bite is the inability to completely close the mouth, resulting in either the front or back teeth of the upper and lower arches not making contact. Additional symptoms of an open bite, along with other teeth misalignments, include:
If you suspect an open bite, it is important to see a specialist orthodontist who can assess your bite and teeth. They will diagnose the condition by performing dental exams and taking X-rays.
The X-rays allow the orthodontist to view beneath the gum line, assisting in detecting the underlying cause of the open bite. After making the diagnosis, your orthodontist will inform you about treatment options suitable for your situation so you can choose the best approach.
Yes, an open bite can lead to several complications affecting the teeth, mouth, and overall health, and it may result in an unattractive smile.
Over time, an open bite can worsen and increase the risk of complications such as periodontitis and excessive wear on the contacting teeth.
Other complications that may arise due to an open bite include:
These complications highlight the importance of addressing an open bite. Children with the condition should be assessed by an orthodontist once their front teeth have fully erupted, typically around the age of 7.
Treatment options for adults, such as braces or Invisalign, often yield excellent results when provided by a qualified orthodontist.
During your initial visit, your orthodontist will discuss various treatment options available to correct an open bite. Ensure that you consult a specialist who uses advanced technology for treatment.
Common treatments for correcting an open bite include:
Open bites are relatively uncommon, affecting around 0.6% of people. However, they can be effectively treated by a qualified orthodontist using braces or Invisalign.
Surgery may be necessary to correct severe open bites. However, standard orthodontic treatments such as braces or Invisalign can address many open bites. A complete dental examination and X-ray will help determine the best treatment approach.
An open bite is a type of malocclusion, or bad bite, where the upper and lower teeth do not meet when the mouth is closed, creating a noticeable gap between the top and bottom arches. If you have a space between your upper and lower teeth, consider consulting your orthodontist for evaluation and treatment.
Orthodontic treatments performed by an experienced orthodontist are generally effective for correcting an open bite. Common correction methods include braces or Invisalign. For severe cases, surgery performed by an oral surgeon may be required in addition to orthodontic treatment.
A night guard, also known as a nighttime mouthguard, is worn to prevent jaw clenching or teeth grinding during sleep. Occasionally, a night guard can cause teeth to shift over time, potentially leading to an open bite. If you use a night guard and are concerned about tooth movement, consult an orthodontist.
Yes, an open bite can worsen over time. It is essential to see an orthodontist for treatment to prevent gum and teeth damage and to alleviate pain when chewing, biting, or swallowing. Early treatment of open bites in children, particularly from the age of 7, can provide long-lasting and effective outcomes.
No, an open bite will not correct itself and may worsen over time, potentially requiring more invasive correction methods. Discuss effective long-term treatment options with a professional orthodontist, which in most cases can include braces or Invisalign.
Yes, thumb-sucking is a common cause of open bites, along with other behaviours like tongue thrusting or improper swallowing patterns that gradually push teeth out of alignment.
Yes, an open bite can lead to speech difficulties such as lisping. If the upper and lower teeth do not close properly, it can affect articulation and make speaking more challenging.
Yes, open bites in adults can be corrected by a professional orthodontist. Treatment can be more complex and may include jaw surgery in severe cases. However, less severe open bites can often be managed with Invisalign aligners or braces.
