Buccal Bifurcation Cysts: Diagnosis and treatment


A buccal bifurcation cyst is a bone cyst that grows in the mandible (jaw), adjacent to the first molars. Although rare, they are more likely to occur among children between the ages of four and fourteen.

The most common symptoms of buccal bifurcation cysts include:

  • Facial pain
  • Facial swelling
  • Swelling inside the mouth around the tooth

Once someone -- whether a pediatrician, dentist, or parent – suspects a problem in the jaw or mouth of a child, it’s best to be referred to an oral and maxillofacial surgeon for diagnosis and proper treatment. An untreated jaw cyst, such as a buccal bifurcation cyst, will grow larger and may end up compromising the tooth or surrounding teeth.

How are buccal bifurcation cysts diagnosed?

Buccal bifurcation cysts are usually identified just prior to eruption of the tooth. They can first be seen via panoramic x-ray or regular dental x-ray. CBCT (cone beam computed tomography) 3D imaging may then be used for more precise images.

At Park Avenue Oral and Maxillofacial Surgery, we offer our patients the significant benefits of these proven, precise and safe diagnostic tools.

What is the treatment for buccal bifurcation cysts?

Treatment of a buccal bifurcation cyst typically involves removal of the cyst, followed by immediate bone grafting of the defect. Sedation dentistry is commonly used to help ensure a comfortable, pain-free and safe procedure. Dr. Cohen is a widely recognized leader in sedation dentistry and the full range of sedation options.

Following the procedure, the patient will receive a prescription for antibiotics and return for a follow-up exam approximately two weeks later. See below before & after x-rays for recently treated patients:
