Dentigerous cysts are a common type of odontogenic cysts. An odontogenic cyst is a fluid-filled sac that develops in the jaw bone over a tooth that hasn’t erupted yet. The cysts, in most cases, affect the molars or canines, and they’re second in prevalence after periapical cysts. These are cystic lesions that result from an infection in a tooth.

What are the symptoms?

Smaller dentigerous cysts might not cause any symptoms. However, if the cyst grows larger than 2 centimeters in diameter, you may notice:

• swelling

• tooth sensitivity

• tooth displacement

If you look inside your mouth, you may also notice a small bump. If the cyst causes tooth displacement, you might also see gaps slowly forming between your teeth.  

How to operate the Dental Cyst Surgery ?

After a thorough examination and X-rays, your dentist will decide which treatment is best for your particular dental cyst.  He/she may decide to remove it and the affected tooth. Alternatively, marsupialisation may be used. This is where a slit is made in the cyst and the slit is then sutured open so the cyst can freely drain itself.
