Find Clinics offering Cyst Removal in London & UK »

A dentigerous cyst is a benign, non-inflammatory cyst thought to be developmental in nature, and is found in the ondontogenic area (i.e.  the teeth). They most commonly develop around the crown of an unerupted tooth, in areas near the upper jaw, where wisdom teeth (sometimes known as third molars) and upper-jaw canines are found. The cyst can often displace a tooth. Most dentigerous cysts are very small and hence difficult to detect. Furthermore, they are by and large asymptomatic. Dentigerous cysts develop most commonly in your twenties, thirties, and forties. Males have a tendency to develop dentigerous cysts over woman.


Occasionally, dentigerous cysts pose a danger as they can become enlarged; to the point where you may be at risk from pathological jaw fracture should your cyst remain untreated. These cysts can lead to expansion of bone, and potentially could cause you facial asymmetry. There is also a risk of infection unless it is dealt with.


To treat a dentigerous cyst, the entire cyst and the cyst lining will both have to be removed; this is done in order to minimise any chance of recurrence. It should be noted that there is no medicine that can help heal your cyst, so surgery should definitely be considered as worthwhile. You will be put under general anaesthetic during this procedure.  As an alternative, and especially in cases where it would be an awful discomfort to you to have you the whole cyst removed, marsupialisation will have to be considered, where the cyst is cut open to be drained, without necessitating the need for removal. Marsupialisation is usually the recommended method of treatment simply due to the fact simple surgical removal could lead to hazardous jaw fracture. Therefore, it is essential that treatment is sought if you suspect you have developed a dentigerous cyst.
