small black spot on side of tongue pretty far back. black spot on lower gums. black spot on side of tongue that is small painless. have a black spot on my lower gums same side of mouth. been have neckaches and headaches. should i be worried?
worrying doesn't cure anything especially anxiety. it would be impossible to determine the nature of these black spots based on a vague description so you will need a hands-on professional opinion. your dentist is skilled in this area but your primary care provider or an ent can also render an opinion.
