What could a painless white bump on my lip be?

When you see a small, white, and pain-free bump on your lip, one common explanation is that it may be a milia. Milia are tiny cysts that form when keratin—an inoffensive protein from your skin—gets trapped beneath the surface. They are harmless and can appear anywhere on the face, including the lips. These bumps are typically smooth, white, and don't cause any discomfort. In some cases, they can be confused with other benign white lesions, like Fordyce spots (small, yellowish bumps that are actually sebaceous glands) or even other types of white patches seen in the mouth. According to updated clinical guidelines, the appearance of such lesions is often evaluated by their location, size, and whether they cause pain. Most times, if they're asymptomatic and stable, no treatment is necessary. However, if the bump changes in size, color, or becomes painful, it's a good idea to get personalized insights by using a free symptom checker or consult with a doctor or dentist for proper evaluation and peace of mind.
