Hemangioma: The dark spots may be a hemangioma of tongue. They are often raised dark or purplish growths caused by swelling and outgrowing of veins, appear like blood bubbles. They are benign but can be removed if get in the way of eating or looks unpleasant. They can appear any time, at many places. We commonly see them on older adults on lips. See dentist to confirm what you see.

See your Dentist: Typically when you see something that looks similar on both sides, it is not a concern. However, it is impossible to diagnose without seeing these spots first hand. I would suggest you consult your dentist. Thanks.

Needs to be seen: These types of situations need to be actually seen in order to give you an accurate diagnosis, and whether or not these spots are normal or not. Anything else would be a disservice to you and unlikely the right answer. Call your dentist for an evaluation.

See a doctor: Dark patch on the tongue may be caused by the natural pigmentation of the tongue and no treatment is needed. If these spots is a cause of alarm or concern, see your doctor for advice and evaluation.
