White upper gums

White areas on the upper gums may be normal anatomy, surface irritation, a fungal coating, a keratotic patch, or another lesion needing assessment.

The upper gingiva can look pale because of its normal keratinized surface, but a new white patch can follow friction, heat, tobacco, chemicals, or infection. Texture, duration, and whether it wipes away help guide examination.

Avoid tobacco, irritants, hot foods, and rubbing while observing it. Keep normal oral hygiene, but do not scrape the patch or apply household chemicals.

Arrange care for a patch that persists, enlarges, feels firm, bleeds, or does not wipe away. Rapid swelling or difficulty swallowing needs prompt attention.

Ask whether this is normal keratin, trauma, thrush, or another lesion, and whether a swab, photograph, or biopsy is needed.
