Hi Dear,
Welcome to HCM.
Understanding your concern.
As per your query you have symptoms of black spots on tongue since almost 17 years which is a matter you should not worry about. It is because of two major reasons in your case. First of all its because of
hyperpigmentation which is a genetic trait that keeps resurfacing and secondly its because of hairy tongue which result from alcohol consumption, a soft diet, poor
oral hygiene,
fungal infection, dry mouth (xerostomia) or excessive use of tobacco.
Need not to panic about it, I would suggest you to try applying rosehip oil, potato juice of puree, aloe vera, lemon juice and cucumber juice to black spots. Sucking on small pieces of pineapple twice a day for one week will lighten spots.
If you want permanent removal of these then you should visit
dermatologist once and get it examined properly. Go for
laser treatment. Cryotherapy is also considered treatment option.
Hope your concern has been resolved.
Get Well Soon.
Best Wishes,
Dr. Harry Maheshwari
