Key Takeaways White patches in the oral cavity can be classified into normal variants, non-pathological patches, and potentially malignant disorders. It is important to identify the cause of the white patch and differentiate between different types. Referrals should be made based on the characteristics of the white patch and the urgency of the situation. Clinical photographs are valuable in referrals and can aid in triaging patients. Ongoing monitoring is important for potentially malignant disorders. Lichen planus can have different types and presentations, and a biopsy may be necessary for certain cases. Enlarged taste buds, particularly in the foliate papillae, are usually bilateral and not a cause for concern. Oral lichenoid lesions can be triggered by dental restorative materials or medications, and a change in dental material may sometimes improve the condition. Smoker's mouth can present with white patches and inflammation in areas where smoke gathers, and counseling patients to reduce smoking is important. Oral submucous fibrosis, often caused by areca nut chewing, requires regular review and counseling patients to stop chewing the nut.
