What are Oral Cysts?
Several forms or types of cysts may develop in the mouth cavity. Oral cysts are
also called dental cysts, as well as periapical, odontogenic or radicular cysts.
Dental cysts are a very common form of an odontogenic cysts. In most cases, such
cysts are caused by infections that result in the pulp or inner portion of the tooth
becoming infected & causing resultant decay, as well as the development of fluid
filled sacs or inflamed tissue. Fluids contained within such as sacs or cysts may
be sterile or infected. If not treated, infectious fluids may be reabsorbed &
spread infection to other locations in the body.
Types of Oral Cysts
- Periapical cyst- also known as a radicular cyst, these are the most common of odontogenic
cyst types. The tooth becomes infected, leading to death of pulp tissues. Infected
matter & toxins may escape through the apex (bottommost portion) of the tooth,
leading to infection of surrounding tissues as well as the development of cysts
caused by skin or gum tissue caused by lack of adequate blood supply.
- Keratocyst- This cyst is often difficult to diagnose, & results pertaining to
content must rely on laboratory tests. They are rather aggressive & can be tricky
to remove, as the cyst can grow into bone formations of the jaw.
- Dentigerous cyst - this type of cyst is the second most common, & develops within
a dental follicle in close proximity to or surrounding an unerupted tooth. These
type of cysts are commonly found around the third molars. These cysts can grow &
alter positioning of teeth, but most do not cause symptoms or pain & often go
- Primordial cyst - this type of cyst develops instead of a tooth & is one of
the rare forms of oral cysts.
Common Treatment for Cyst Removal (Cyst Operations)
The most common & beneficial treatment for cysts is excision or removal of the
cyst. Before removing the cyst, the dentist or oral surgeon generally performs a
biopsy, which involves the removal of a small portion or piece of tissue from the
questionable cyst. The tissue sample is then sent to a laboratory where examination
& analysis will be performed.
Cysts in mouth commonly form around the wisdom teeth, around impacted wisdom teeth,
& in the pulp of teeth, & while the cyst itself might be benign, or harmless,
dentists & oral surgeons most frequently suggest their removal before surrounding
tissues or bone structures are damaged.
Cyst operations are generally performed under local anesthesia meaning the patient
is awake during the procedure. In most cases, cysts are removed quickly & efficiently
in under an hour. Large cysts a require more detailed or extensive surgery, which
may or may not require bone reconstruction.
Who Benefits from Cyst Operations?
Anyone who has noticed or been diagnosed with a cyst in any portion of the oral
cavity will benefit from its removal. If left untreated, cysts may cause ensuing
infection or spread of infection to surrounding teeth, gum, or other mouth tissues.
