FAQ
Frequently Asked Questions
No, most leucoplakia patches are benign. However, they are considered 'potentially pre-cancerous' because a small percentage can show early signs of cancer or develop into cancer over time, which is why medical evaluation is crucial.
The exact cause is unknown, but it is strongly linked to chronic irritation. The most common risk factors are tobacco use (smoking or chewing), excessive alcohol consumption, and chronic friction from rough teeth or ill-fitting dentures.
Oral thrush (candidiasis) is a fungal infection causing white patches that can usually be scraped off, leaving a red, raw area. Leucoplakia patches are firmly attached and cannot be wiped or scraped off.
The primary step is removing the source of irritation (e.g., quitting tobacco). The patch itself may be removed surgically, with a laser, or by freezing if it shows signs of cellular changes (dysplasia) or is suspicious, to prevent potential cancer development.
