Hi Dear, Welcome to HCM. Understanding your concern. As per your query you have white spots on lips . Well there can be many things that cause white bump on lips / Bu the most probable cause for white bump on lip is fordyce granule or spot . Fordyce granules or Sebaceous Prominence, are small raised, pale red, yellow-white or skin-colored bumps or spots .Fordyce spots are a type of ectopic sebaceous gland . Although they are harmless and require no treatment but If they persists for longer period then there is few treatment options like electro surgery , laser therapy ( Pulsed dye lasers ) and punch technique . I would suggest you to consult dermatologist for proper examination . Doctor may examine carefully and rule out causes like canker sore , cold sore , bacterial infection or oral cancer . For now give cold compresses and apply raw honey at night . Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
