Causes of irritation
Irritation may occur as a result of minor dental procedures. In addition the use of dentures or orthodontic appliances may result in soreness or canker sores. In some cases patients may be unable to maintain effective oral hygiene e.g. total care geriatrics, leading to irritation.
Orthodontic discomfort is a common response to the adjustment of braces. Patients may experience tooth sensitivity for three to five days after adjustment, and irritation of the lips, cheeks and tongue for one to two weeks1.
