I am sorry to hear you have been having bleeding gingiva (gums). You did not mention if the bleeding was spontaneous or if it occurred while you were brushing your teeth. If you could get back to me on that it would be helpful.
Typically bleeding gums are associated with gingivitis - inflammation of the gums without involvement of the bone - or periodontal disease which usually presents as gingivitis with associated bone loss.
You mentioned that you have good oral hygiene so I am assuming that you have been seeing your dentist regularly over the years. This means that you probably have a series of X-rays from past years. If you have not had a recent set you should consider having a full mouth series of X-rays taken now so your dentist can compare your current bone level to years past.
I would also consider having a consultation with a periodontist for a second opinion. Bring copies of your current and past X-rays for the periodontist to look at as well.
If the bleeding is not tooth related or it does not get better following dental hygiene treatment or periodontal treatment you should consider having a biopsy taken to get a diagnosis and confirm that the bleeding is a local problem confined to the mouth alone.
Thanks for providing a photo! Although I cannot diagnose on line what you are describing (and showing) seems consistent with a mucocele. Mucocele are some of the most common lesions seen inside the mouth, they are completely benign and most are secondary to trauma.
Everyone has between 700 and 1000 minor salivary glands - you can feel them if you push your tongue up against your lower lip, they feel like small bumps just under the skin - and three pairs of major salivary glands.
The minor salivary glands are easily traumatized and form a 'water balloon' either when the duct (the tube that connects the gland and the inside of the mouth) is either blocked or severed.
Normally mucocele will go away on there own within a week. If it does not go away it may need to be removed by an oral surgeon in a very minor surgical procedure.
I am sorry that your husband has been having a decrease/change in his taste sensation. Although I cannot diagnose online I can tell you that the likelihood of the decrease/change in taste is probably not due to his surgery as there are no taste buds on the gum tissue.
Unfortunately there is very little written about taste disturbances other than that they are often associated with changes in ability to smell as well.If your husband has not seen an Ear Nose and Throat (ENT) doctor you might want to have him make an appointment for an assessment.
The other possibility is to contact a dental school near you, you can look at the American Dental Educators Association website for specific school locations near you, and ask if they are doing any clinical research on taste disturbances or if they have a dentist in the faculty who is knowledgeable about the subject.
Unfortunately what you are describing is not specific enough for me to provide accurate guidance with respect to the red stripe on your tongue.
What I can tell you is that it is absolutely not caused by the same virus that causes cold sores. In healthy patients the virus that causes cold sores only develops on non movable mucosa specifically the gingiva (gum tissue) or hard palate.
The virus that causes cold sore is a non sexually transmitted human herpes virus and when 'cold sores' develop inside the mouth they never occur on movable mucosa (inside of the lips, cheek, tongue, floor of the mouth).
I suggest that you see your dentist or physician for a more definitive diagnosis and treatment suggestions.
I am sorry you have been having some discomfort on the underside of your tongue. Although I cannot diagnose online I hope to provide some guidance.
There are numerous structures that are normally seen under the tongue including frenum which attaches the mid-line of the posterior (back) part of the tongue to the floor of the mouth, these often have tissue tags similar to the appearance of a tissue tag on the skin.
The under surface of the tongue itself contains blood vessels, connective tissue, minor salivary glands, fat and nerve. Without seeing the affected area I cannot give you a definitive diagnosis.
The possibility exist that the are still hurts because you are playing with it and that the tissue is not dead at all, just irritated. I suggest you see an oral surgeon if you want a definitive diagnosis they will need to a biopsy. You can also show the affected area to your general dentist who should be able to give you a better idea of whether a biopsy is indicated and they can provide you with a referral if needed.
I am sorry you have been having difficulty finding a correct diagnosis and appropriate treatment plan. Unfortunately I cannot diagnose online. I strongly suggest that you see either an oral surgeon for a definitive diagnostic procedure (biopsy) or a dental specialist in either oral pathology or oral medicine.
If you have a Dental school near you this may be the best place to start as all three specialist will be at the same location. You can look on the American Dental Educators Association website to find either a dental school or a hospital with a general dental residency or a residency in oral surgery.
I hope that this helps and that you will soon be feeling better.
I am sorry you are having a difficult time however changes in the color of the tongue are relatively common and normal and generally pass quickly. They are often associated with the color of specific foods or lozenges and will fade as the 'stain' is washed out by the saliva.
Since you are having both oral and fecal color changes I suggest that you return to the physician who prescribed the anti fungal medications and show them the color change in your mouth and ask if they need a stool sample as well.
Although I cannot diagnose online what you are describing sounds like a variation of normal racial pigmentation. As long as the brown spots do not change in size, shape or color there is very little to worry about.
The next time you see your dentist for a check-up point out the dark spots and ask for a diagnosis. If it is important for you to have a definitive diagnosis you can request a biopsy of the affected area.
In general when my patients complain of bad breath I recommend that they first see a Dentist or Dental Hygienist who can remove calculus ("tarter") build up around the teeth and below the gum line. They can also address any infections or obvious sources of smell like gum disease, periodontal (bone) disease or broken teeth.
If seeing the Dentist or Hygienist has not solved the problem I typically recommend the patient see an Ear Nose and Throat doctor to confirm that the smell is not coming from a sinus infection and, if that does not solve the problem I would suggest seeing a gastroenterologist (GI) specialist and make sure the problem is not coming from the stomach.
Typically however the solution is local and related to gum disease and periodontal disease so see a dentist first. You can look on the American Dental Educators Association website to find out if there is a Dental School or Dental Hygiene School or Hospital with a dental department near where you live. They can offer a second opinion on your oral health and provide a lower cost alternative to private care.
