Food debris and bacteria are easily trapped in the space between the crown of the wisdom tooth and the overlying gingiva (gum), resulting in the infection of the periodontal tissues (Pericoronitis). Furthermore, the infected, swollen overlying gingiva is often bitten by the opposing tooth making it difficult to recover.

Pericoronitis has the following signs and symptoms:

Bad breath

Dental Caries

Since it is difficult to clean the surfaces between the impacted tooth and the adjacent tooth in front, dental plaque will accumulate there and cause Dental Caries on these tooth surfaces.

Root resorption of the neighbouring tooth

The inflammation of the periodontal tissues caused by the dental plaque, together with the pressure of the wisdom tooth pushing on the adjacent tooth in front, may cause the root of the adjacent tooth to resorb.

Causes pathological changes, such as cysts.
