Cyst on the Gums in Dogs

Dentigerous Cyst in Dogs

 

A dentigerous cyst is, literally, a cyst on the tooth. It is characterized by a fluid filled sac, similar in form to a blister, which has originated from the tissue surrounding the crown of an unerupted tooth. It occurs in any breed that is at an increased risk for impaired eruption, such as boxers and bulldogs. It tends to occur in the mandibular (lower jaw) first premolars, and often on both sides (bilateral). This condition is diagnosed if the teeth are unerupted at six months old, but a cyst may not form until later, if ever.

 

Symptoms and Types

 

The symptoms can include one or more of the following:

 

  • "Missing" tooth
  • Formation of a soft swelling at the site of a missing tooth, often fluctuant with fluid
  • The patient may show evidence of a pathological (abnormal) fracture of the lower jaw due to cystic damage to the surrounding bone, with no previous indication of a problem
  • Cystic changes may be initially unapparent

 

Causes

 

Unerupted teeth.

 

Diagnosis

 

Your veterinarian will search for an oral mass - a benign tumor that forms at the root of a tooth. Tooth structures (complex or compound) are sometimes contained within a cystic structure, that is, the tooth is covered in gum tissue that resembles a sac, but with different levels of organization. Radiographic imaging is essential in any instance of missing or unerupted teeth, and is often used to get a definitive diagnosis. Radiographic results may show evidence of a radiolucent (invisible to x-ray) cyst originating from the remaining enamel organ at the neck of the tooth, and enveloping the crown (a halo).
