A lump in the oral mucosa

A lump on the mucosa of the cheek or lip is usually caused by a trauma, for example, excessive tissue growth due to biting in the cheek. Such growth can also be caused by an ill -fitting and chafing dental prosthesis. Especially on the lower lip, a lump can sometimes be a blueish eminence, a so-called mucocele, which is caused by damage to a salivary gland’s duct. Sometimes papillomas and warts are also encountered in the mouth. On rare occasions, there can also be tumours in the oral mucosa.

A lesion in the oral mucosa

A lesion in the oral mucosa is usually caused by a trauma, such as biting in the cheek or tongue, or a sharp edge of a tooth or a prosthesis chafing the location. Other causes for lesions include aphthae or lichen ruber planus. If a lesion has not healed within two weeks of eradicating the possible cause, it should be shown to a dentist.

A dark spot

A dark grey or brown spot in the gums is usually caused by amalgam entering the tissue during removal ofan amalgam filling or extraction of a tooth. Excessive pigmentation caused by smoking is usually found in the gums of the front area of the mouth. Rarely, also some other types of benign pigment changes, such as melanin spots or moles, can appear in the oral mucosa. Melanoma in the oral mu cosa is extremely rare, and if discovered, it is usually in the gums or in the palate.

A light-coloured lesion

A light-coloured area in the oral mucosa can be, for example, a thickening of the mucosa (hyperkeratosis) caused by a chafing tooth, oral lichen ruber planus, yeast infection, hairy tongue, or so -called leukoplakia. Using snus (moist snuff) can also cause a light-coloured change in the location where the tobacco is placed. If the lesion does not disappear within two weeks of eradicating the possible cause, it should be shown to a dentist.


The most common cause for redness in oral mucosa is a yea st infection. Symptoms can include sensitivityand stinging sensations of the mucosa. Factors exposing the mucosa to yeast infection include dryness of the mouth, smoking, prostheses, lichen ruber planus and courses of antibiotics. Other causes behind redness of the oral mucosa include geographic tongue, lichen ruber planus, so -called glossocele or, rarely, an allergic reaction. Generally, all lesions appearing as redness of the oral mucosa should be examined and diagnosed by a dentist.

Burning mouth syndrome

A burning sensation on the tongue, lips and/or in the hard palate is usually experienced by middle -aged women. The reason behind the symptoms is not known, but it can be caused by an interference in the function of the neurofibrils of the sensory nerve. The condition can also be accompanied by a feeling of dryness in the mouth and a change in the sense of taste or feel in the mouth. Normally the oral mucosa looks healthy, and the problem as such is not dangerous. Chewing gum or sucking on a mint can help to alleviate the symptoms. If required, the pain can also be alleviated by taking medication.
