The prognosis for<unk>  depends on the depth of the impaction. When they lack a communication to the mouth, the main risk is the chance of a cyst or neoplasm forming in the tissues around the tooth (such as the dental follicle), which is relatively uncommon. Once communicating with the mouth, the onset of disease or symptoms cannot be predicted but the chance of it does increase with age. Less than 2% of<unk><unk>  are free of either periodontal disease or caries by age 65. Further, several studies have found that between 30% – 60% of people with previously asymptomatic<unk>  will have them extracted due to symptoms or disease, 4–12 years after initial examination. Extraction of the<unk><unk>  removes the disease on the<unk>  tooth itself and also appears to improve the periodontal status of the second molar, although this benefit diminishes beyond the age of 25.
