The healthy lining of the mouth is generally a consistent pink colour. The appearance of red or white patches that cannot be wiped away may indicate changes in the cells of the oral mucosa. While some patches are harmless, others may be signs of chronic irritation or pre-cancerous conditions. It is important to monitor the mouth regularly for any such colour variations.
White patches, often referred to as leukoplakia, are frequently associated with long-term irritation from smoking, tobacco use, or friction from a sharp tooth or ill-fitting denture. These patches are usually painless but can vary in size and texture. Red patches, known as erythroplakia, are generally less common but carry a higher risk of being associated with serious cellular changes and should be evaluated promptly.
In some cases, a patch may be a mix of both red and white colours. These speckled patches require careful clinical assessment by a dentist. A registered professional will evaluate the history of the patch, its location, and any associated risk factors. They may recommend a biopsy, which involves taking a small sample of the tissue for laboratory analysis to determine the exact nature of the lesion.
Early identification of these patches is a key part of preventive dental care. Patients should not attempt to self-diagnose or treat these areas with over-the-counter remedies. If you notice a patch that lasts longer than two weeks, schedule an appointment with your dentist. Regular check-ups ensure that any changes in the mouth are documented and managed appropriately before they progress into more serious conditions.
