Another very common cause of white patches in the mouth is frictional or irritational trauma leading to keratosis. Examples include nicotine stomatitis, which is keratosis in response to heat from tobacco smoking (rather than a response to the carcinogens in tobacco smoke). The risk of malignant transformation is similar to normal mucosa.
White sponge nevus (WSN) is an extremely rare autosomal dominant [4] condition of the oral mucosa (the mucous membrane lining of the mouth). It is caused by one or more mutations in genes coding for keratin , which causes a defect in the normal process of keratinization of the mucosa.
Frictional keratosis: This typically presents as white plaques on the oral mucosa due to mechanical trauma. When the cause of frictional keratosis is removed the white patch may resolve. Hyperplastic reactive lesions or nodular swellings: These occur in the oral mucosa due to low grade inflammation or trauma. They develop where the mucosa is ...
The causes vary, but are often rooted in excess oil and bacteria on the face, chest, or back, which can be triggered by hormonal issues, stress, certain foods, and irritating products.
Dental plaque is a biofilm of microorganisms (mostly bacteria, but also fungi) that grows on surfaces within the mouth. It is a sticky colorless deposit at first, but when it forms tartar , it is often brown or pale yellow.
It is caused by Coxsackie A and B virus, and lesions or blisters are found bilaterally on the hands, feet and mouth of the patient. [16] Oral candidiasis: Also known as thrush, herpetic gingivostomatitis can often be differentiated from these microorganism/bacterial causing white plaques on the palate, buccal mucosa, tongue, oropharynx etc. [16]
Acute atrophic candidiasis may feel like the mouth has been scalded with a hot liquid. [5] Another potential symptom is a metallic, acidic, salty or bitter taste in the mouth. [5] [8] The pseudomembranous type rarely causes any symptoms apart from possibly some discomfort or bad taste due to the presence of the membranes.
