I have been plagued for many years with white stringy mucous inside my lips and gums.  I visit the Dentist at least twice per year and brush twice per day.  I usually dont use mouthwash and I do floss.  No-one can tell me what is causing this and how to get rid of it.  Please help!!  Regards, Lyn.
Hiwelcome to ChatDoctorAs you mentioned the white string in your mucous membrane must be a possibility of lichen plans. Be clear is it patch or string. If white patch then can be like candidiasis, leukoplakia. Or you have habit of chewing tobacco or smoking. If you don't have any habit of chewing or smoking then, check weather the white strings are only inside mouth or anywhere else on skin. Not to worry much, it will be lichen plans. Not to take stress, because it may increase because of that. Start anti oxidant Longer once a day. Visit your dentist for clarify the lesion. Hope it will help you thank you
