It is a common experience to notice unusual textures or what might feel like small “flaps” on the inside of the cheeks. These observations are frequently benign and represent normal anatomical variations or minor irritations. Understanding these common features can help alleviate unnecessary worry.
Normal Features of the Inner Cheek
The inner lining of the cheek, known as the buccal mucosa, contains several normal structures. One common finding is the linea alba, which appears as a horizontal white line along the inside of the cheek. This line forms where the upper and lower teeth meet, and results from chronic friction or pressure from chewing habits. It is a harmless condition, often compared to a callus.
Another normal anatomical feature is the parotid papilla, a small, often subtle, bump located on the inner cheek. This papilla is typically situated opposite the second upper molar tooth. It is the opening of the parotid duct, transporting saliva into the mouth. Both the linea alba and the parotid papilla are natural parts of oral anatomy and are generally asymptomatic.
Common Reasons for Cheek Irregularities
Chronic cheek biting, medically termed morsicatio buccarum, is a frequent cause. This habit leads to a thickening and roughening of the buccal mucosa, which may appear as white, grey, or shredded patches. The affected tissue can sometimes have a ragged surface, and small sections may occasionally detach.
Irritation from dental appliances or sharp tooth edges can also cause noticeable changes to the cheek lining. Orthodontic braces, ill-fitting dentures, or even a chipped tooth can create persistent friction against the inner cheek. This continuous rubbing can lead to localized inflammation, redness, or the development of small, smooth, often pinkish, fibrous growths known as fibromas. These irritations are generally benign, though they can cause discomfort or tenderness.
When to Seek Medical Advice
Certain signs and symptoms warrant professional evaluation by a dentist or doctor. Seek medical attention if a sore or lesion on the inside of the cheek does not heal within two weeks. Persistent pain, bleeding, or a rapid increase in the size of any lump or patch are also concerning indicators.
Changes in color, such as new red or white patches that cannot be wiped away, should be investigated. Difficulty with chewing, swallowing, or speaking, along with any numbness or loss of sensation in the mouth, are additional symptoms that require prompt assessment. Early detection is important for any potentially serious conditions, even though the vast majority of cheek irregularities prove to be benign.
